Introduction. Despite the established guidelines on lower extremity free flap reconstruction by the British Orthopaedic Association Standard for Trauma (BOAST-4) the post-operative care has yet to be standardised. There is currently no coherent evidence in the literature regarding clinical monitoring, warming, dangling and compression; the optimal regimes and their respective physiological benefits. The aim of this study is to survey all UK Major Trauma Centres (MTCs) with regards to the post-operative care of lower extremity free flaps and elucidate the current protocols for clinical monitoring, warming, dangling and compression. Materials & Methods. All UK-based adult MTCs were surveyed. We formulated a detailed questionnaire to enquire about the post-operative care of lower extremity free flap reconstructions; the number of free flap reconstructions per month and take backs per month and for which post-operative methods a protocol is used in each MTC. We asked specific questions concerning: clinical monitoring, warming, dangling and compression. This questionnaire was distributed to consultant leads in the form of multiple choice questions, with an option of free-text box for further comments, using JISC online surveys. Results were analysed in Excel and presented in percentages. Results. The 28 adult MTCs were contacted. The results showed a lack of formal regional protocols with great variability, suggesting there is no general consensus on post-operative care of lower extremity free flap reconstructions with regards to clinical monitoring, warming, dangling and compression. Conclusions. This survey of UK MTCs on the post-operative protocols for lower extremity free flap reconstruction demonstrated lack of evidence, consensus and large variability in common practice which requires standardisation

Aim. To report outcomes of soft tissue reconstruction using free tissue transfer for the treatment of tibial osteomyelitis as part of a single-stage, ortho-plastic procedure. Method. Patients who underwent ortho-plastic reconstructive surgery to excise tibial osteomyelitis in combination with free tissue transfer in one stage were included. Patients underwent surgery between 2015 and 2024 in a single specialist centre within the UK. Baseline patient information, demographics, and infection information was recorded. Adverse outcomes were defined as (i) flap salvage required, (ii) flap failure and (iii) recurrence of infection. Patient reported quality of life was measured using the EuroQol EQ-5D-5L index score. Pre-operative QoL was compared to QoL at 1 year with a control group of 53 similar patients who underwent surgical treatment for tibial osteomyelitis without a free flap (local flap or primary closure). Results. Ninety-three patients were eligible for inclusion, with a mean age of 52 years (range 18–90). 77/93 (82.8%) had a free muscle flap with the remainder (17.2%) receiving a fasciocutaneous flap. The donor tissue was defined as 57 gracilis, 6 latissimus dorsi, 14 hemi-latissimus dorsi, and 16 anterolateral thigh. The recipient area of the tibia was distal 1/3 in 52 cases, middle 1/3 in 27 cases and proximal 1/3 in 12 cases. The average flap ischaemic time was 70 minutes (range 28 to 125). Seven patients (7.5%) required urgent flap salvage at a median time of 1.0 day (range 0.5 – 4.0). Of these, 4 (4.3%) went on to have total flap failure, of which 2 patients underwent below knee amputation subsequently. Flap failure was due to either arterial (n=2) or venous (n=2) anastomotic thrombus. There were 3 (3.2%) episodes of confirmed infection recurrence within the first year after the index procedure. EQ-index scores at 1-year post-operatively were significantly improved when compared to pre-operative scores (p=0.008). At 1-year post-operatively, EQ-index scores in patients who underwent free flap was similar compared to local flaps (p=0.410) and in those who underwent primary closure for tibial osteomyelitis (p=0.070). Conclusions. Microsurgical single stage surgery can achieve high flap survival rate (95.7%). Free flaps fail early due to anastomotic thrombus with no late failures seen. Free tissue transfer does not appear to give inferior QoL compared to matched patients with local flaps or direct closure in tibial osteomyelitis

Open tibial fractures have a high infection risk making treatment difficult and expensive. Delayed skin closure (beyond 7 days) has been shown to increase the infection rate in several studies (1). We aim to calculate the cost of infection as a complication of open tibial fractures and to determine the effect of delayed skin closure on this cost. We retrospectively reviewed all records of patients treated with a free flap in our institution for an open tibial fracture from 2002 to 2013. We calculated direct costs of treatment by the DRG-values (2014 figures), based on length of stay (LOS), diagnosis, orthopaedic and plastic surgical procedures and the corresponding reimbursement. The primary goal was to establish the extra cost incurred by an infection, compared to treating an uninfected open tibial fracture. The cost efficiency saving of early soft tissue cover was also investigated. We analysed 45 injuries in 44 patients. All patients were treated with debridement, stabilization, prophylactic antibiotics and free flap cover. Infection increased the mean total LOS in hospital from 28.0 to 63.8 days. The presence of an infection increased the cost of treatment from a mean of €49.301 for uninfected fractures compared to a mean of €67.958 for infected fractures. Achieving skin cover within 7 days of injury decreased the infection rate from 60% to 27% (total series rate 48%). The provision of early soft tissue cover (before 7 days) for all patients would have saved an average of €18.658 per patient. The development of an infection after a severe open tibial fracture greatly increases the cost of treatment. Early soft tissue cover is one aspect of care which has been shown to improve clinical outcomes. This study confirms that it will also reduce the cost of treating these complex fractures – underscoring the need for rapid referral and an ortho-plastic setup to handle them. We have only calculated the direct costs of treatment. Infected fractures will also consume extra costs in rehabilitation and absenteeism from later infection recurrence and non-union. Therefore, our estimate of the potential saving is likely to be conservative

The Orthopaedic Unit at The Alfred has been using an external fixator in a novel configuration for protecting lower limb wounds after free flap surgery (sometimes even in the absence of a concomitant bony injury). This soft-tissue frame allows the limb to be elevated without contact so that there is no pressure on the flap and its pedicle. Thus, optimising the arteriovenous circulation. We report our initial experience with these soft tissue frames. The soft tissue frame is not necessarily applied for definitive fracture care, but constructed or modified to optimise elevation of the leg, remove direct pressure from the soft tissues, and stabilise the muscles adjacent to the flap. All ankle-spanning frames held the foot in a plantargrade position to optimise blood flow and recovery (prevent equinus), and minimise intra-compartmental pressure. During 2007, the Plastic Surgery Unit performed 23 free flaps to the lower limbs of 22 patients. Five of these patients had a soft-tissue frame constructed. One patient had a frame applied purely to manage the soft tissue injury, and the other four, who required an external fixator for a bony injury, had their frame modified. Four of the five patients study patients were injured in motor vehicle accidents and one was injured in a simple fall. All five free flaps survived and none required any further surgery. No patients suffered complications (such as bleeding, pin-track infections, or osteomyelitis) related to the soft tissue frame. We strongly recommend considering an external fixator in a modified configuration after lower limb free flap surgery. Constructing a soft tissue frame has no added risks if the fixator is already required. In the case where there is no bony injury, a soft tissue frame has the benefits of providing optimal flap conditions and maintaining anatomical joint alignment. However, this must be balanced against the small risk associated with the insertion of pins (such as infection) and the need for an extra procedure to remove the frame. As always, treatment must be tailored to the individual patient

Chronic osteomyelitis is a challenging clinical problem. Aggressive debridement, bony fixation, obliteration of dead space and vascularised soft tissue coverage with appropriate antimicrobial therapy are essential to successful management of this condition. The gracilis muscle flap is the workhorse flap in our unit for reconstruction of limb osteomyelitis. We describe the experience and use of this flap in our unit over a 3 year period. Clinical records were reviewed from a prospectively-maintained Oxford Free Flap Database and patient notes. All patients who received a free gracilis flap reconstruction as part of the treatment of osteomyelitis between 2011 and 2014 were included in the study. 40 patients received free gracilis flaps; 38/40 for lower limb and 2/40 for upper limb osteomyelitis. Two were myocutaneous flaps, and the remainder were muscle only. The return to theatre rate was 12.5% with a total flap loss rate of 5%. Other flap-specific complications include partial flap loss (2.5%), flap site haematoma (2.5%), donor site haematoma (2.5%) and seroma (2.5%). General complications included pulmonary embolism (2.5%) and death from sepsis (2.5%). All but 2 patients were treated successfully and remain disease free following their initial surgery, with a mean follow up of 12.4 months (range 1–23 months). We have found that the free gracilis muscle flap is effective in the successful treatment of osteomyelitis, with a low complication rate

Introduction. We aimed to determine whether there are differences in patient-reported quality of life (QoL) outcome between local flap versus free flap. Materials and Methods. All patients admitted with lower limb open fractures were retrospectively reviewed. Patient notes were assessed for demographics, time to fracture union, wound healing and patient-reported QoL with EQ-5D-5L, alongside a novel flap assessment tool. Results. A total of 40 patients had flap reconstruction of their lower limb injury; 23 local flap (Group I) and 17 free flaps (Group II). The average length of follow-up was 33.8 months. Group I - 10 revisions of flaps (43.5%) and 14 surgical complications (60.9%). Fracture union was 171 days and wound healing 130 days. EQ-5D index and EQVAS scores were 0.709 and 79.3, respectively. Group II – 8 revision of flaps (47.1%) and 12 surgical complications (70.6%). Fracture union was 273 days and wound healing 213 days. EQ-5D index and EQ-VAS scores were 0.525 and 57.2, respectively. Aesthetic appeal - 48% Group I vs. 66% Group II. Significant differences were found between the two flap groups with higher scores for daily living in Group I (p–0.007) compared to higher overall flap ratings in Group II (p–0.049). Both groups were comparable in terms of complications, while flap congestion and dehiscence were more common with free flaps. statistical interrogation did not elicit significance (p > 0.05). Conclusions. Local flap and free flap techniques offer distinct advantages. Local flaps have a better surgical outcome and patient-reported QoL in the first few years post soft tissue reconstruction. Differences between local and free reconstructive techniques in terms of patient health and function are ameliorated in the longer term

Aim. Bone infections often manifest with soft tissue complications such as severe scarring, fistulas, or ulcerations. Ideally, their management involves thorough debridement of infected bone and associated soft tissues, along with achieving stable bone structure, substantial tissue coverage, and long-term antibiotic therapy. The formation of a multidisciplinary team comprising orthopedic surgeons, plastic surgeons, and infectious disease specialists is essential in addressing the most complex cases. Method. We conducted a retrospective study during six years (2018-2023) at our university center. Focusing on the most challenging cases, we included patients with bone infections in the leg and/or foot requiring free flap reconstruction. Each patient underwent simultaneous bone debridement and reconstruction by the orthopedic team, alongside soft tissue debridement and free flap reconstruction by the plastic surgery team. Targeted antibiotic therapy for either 6 weeks (acute) or 12 weeks (chronic osteitis) was initiated based on intraoperative cultures. Additional procedures such as allografts, arthrodesis, or autografts were performed if necessary. We analyzed the rates of bone union, infection resolution, and limb preservation. Results. Forty-five patients were enrolled. Twenty-four patients (53.3%) had urgent indications (e.g., open infected fractures, osteitis, acute osteoarthritis, or wound dehiscence), while 21 (46.7%) underwent elective surgery (e.g., septic pseudarthrosis or chronic osteitis). Two patients underwent amputation due to flap failure (4.4%), and one patient was lost to follow-up. Follow-up of the remaining 42 patients averaged 28 months (range: 6–60 months). During this period, 35 patients (83.4%) experienced no recurrence of infection. Similarly, 35 patients (83.4%) achieved bone union. Overall, the rate of lower limb preservation was 93.3%. Conclusions. Managing bone infection coupled with soft tissue defects brings significant challenges. Although the majority of patients treated here belong to a complex framework based on the BACH classification, the outcomes achieved here appear to align with those of the simpler cases, thanks to optimal care with a dedicated septic ortho-plastic team. Our study demonstrates a notable success rate in treating infection, achieving bone consolidation, and preserving lower limb function

Aim. Calcaneal osteomyelitis remains a difficult condition to treat with high rates of recurrence and below knee amputation; particularly in cases of severe soft tissue destruction. This study assesses the outcomes of combined ortho-plastics treatment of complex calcaneal osteomyelitis. Method. A retrospective review was performed of all patients who underwent combined single stage ortho-plastics treatment of calcaneal osteomyelitis (2008- 2022). Primary outcome measures were osteomyelitis recurrence and BKA. Secondary outcome measures included flap failure, operative time, complications, length of stay. Results. 33 patients (16 female, 17 male, mean age = 54.4 years) underwent combined ortho-plastics surgical treatment for BACH “complex” calcaneal osteomyelitis with a median follow-up of 31 months (s.d. 24.3). 20 received a local flap, 13 received a free flap. Fracture-related infection (39%) and diabetic ulceration (33%) were the commonest causes. 54% of patients had already undergone at least one operation elsewhere. There were seven cases of recurrent osteomyelitis (21%); all in the local flap group. One patient required a BKA (3%). Recurrence was associated with increased mortality risk (OR 18.8 (95% CI 1.5–227.8), p=0.004) and reduced likelihood of walking independently (OR 0.14 (95% CI 0.02–0.86), p=0.042). Local flap reconstruction (OR 15 (95% CI 0.8–289.6), p=0.027) and peripheral vascular disease (OR 39.7 (95% CI 1.7–905.6), p=0.006) were associated with increased recurrence risk. Free flap reconstruction took significantly longer intra-operatively than local flaps (443 vs 174 minutes, p<0.001), but without significant differences in length of stay or frequency of out-patient appointments. Conclusions. Single stage ortho-plastic management was associated with 79% eradication of infection and 3% amputation in this complex and co-morbid patient group. Risk factors for failure were peripheral vascular disease and local flap reconstruction. Whilst good outcomes can be achieved, this treatment requires high levels of in-patient and out-patient care

Aim. This study investigated the management and clinical outcomes of patients treated for confirmed fracture-related infection (FRI) at 3 centres, in the UK and the Netherlands between 2015 and 2019. Method. All patients with FRI, confirmed by the FRI Consensus Definition. 1. and treated surgically, were included. Data were collected on patient characteristics, time from injury to FRI surgery, soft tissue reconstruction, type of stabilization and use of local antibiotics. All patients were followed up for at least one year. The rates of eradication of infection and union were assessed. The associations between treatment methods, time from injury and outcomes were determined. Results. 433 FRIs were treated in patients with mean age 49.7 years (range 14–84). FRI affected the tibia in 226(52.2%), femur in 94(21.7%), pelvis in 26(6%), humerus in 20(4.6%) and foot bones in 19(4.4%). Patients were followed up for a mean of 26 months (range 12–72). Overall, eradication of infection was successful in 86.4% of cases and 86% of unhealed infected fractures were healed at final review. 3.3% required amputation. Successful outcome was not dependent on age, or time from injury (recurrence rate 16.5% in FRI treated at 1–10 weeks after injury; 13.1% at 11–52 weeks; 12.1% at >52 weeks: p=0.52). Method of stabilization had a major affect on outcome. Debridement and retention of a stable infected implant (DAIR) had a failure rate of 22.3%, implant exchange (to new internal fixation) 16.7%, conversion to external fixation 7.4%. DAIR was significantly worse than conversion to external fixation (p=0.01). There was no effect of the time from injury on the outcome of DAIR or any other fixation method. The use of a free flap in the tibia improved the success rate from 80.4% to 92.1% (p=0.044). Outcome was adversely affected by use of a split skin graft alone in soft tissue reconstruction (44% failure) (p=0.006). The use of local antibiotics reduced the recurrence rate from 18.3% to 10.3% (p=0.022). Conclusions. This study is the first to consider outcome for all FRIs, at all-time points, with all treatment modalities. Treatment was mostly successful but may be improved with better directed use of free flaps, local antibiotics, and limitation of DAIR. The results suggest that the division of FRIs into categories based on time from injury, may not be helpful with modern treatment

Background. Infected total knee arthroplasties present in a variety of different clinical settings. With severe local compromise and draining sinus tract around the knee, after adequate debridement, the resultant patellectomy with need for free muscle transfer and split thickness skin graft for closure, usually results in loss of quadriceps function. This necessitates the need for drop lock brace. No good mechanisms are available for reconstruction of large anterior defects in total infected total knees where this occurs. Questions. Can proximal placement of the knee joint with longer tibial segments aid in closure in patients with large anterior skin defects, and can this placement aid in quadriceps reconstruction to alleviate the need for drop lock braces while ambulating?. Methodology. 10 patients with 2 year follow-up with stage III-C-3 McPherson infected total knees presented with large soft tissue defects over the anterior aspect of the knee with sinus tract and scarring from multiple surgeries. The patients underwent a one stage treatment of the infected total joint. 4 required a free muscle flap and split thickness skin graft. Patellectomy with some quadriceps resection was required in the debridement process. Distal femur and proximal tibial replacements were performed with proximal placement of the knee joint. The patients were analyzed for extension control in gait and soft tissue closure over the operational knee joint. The quadraceps mechanism was over attached to the proximal tibial component. Results. Of 10 with 2 year follow up, none recurred with infection. There was no erosion of the soft tissue over the knee joint commonly seen in free flaps directly over the joint in these type of resection –replacements. 50% of the patients had enough extensor use to walk with a cane or walker as opposed to needing a drop lock knee brace. Discussion. Proximal placement of the knee joints in patients with large anterior soft tissue defects may lessen need for free flaps and provide for extension to lock hinges. Conclusion. Proximal placement of the total knee in case of infected total knees with large anterior soft tissue defect, provides for more quadriceps function and soft tissue coverage and lessened the need for free flaps

Introduction. Fracture related infection (FRI) is a challenging complication to manage in an orthoplastic setting. Consensus guidelines have been created to standardise the diagnosis of FRI and comprise confirmatory and suggestive criteria. In this study, the aim is to assess the diagnostic criteria and management of FRI with a particular focus on soft tissue reconstruction. Materials & Methods. A retrospective study to identify the outcomes of FRI in the lower limb over a five year period at a Major Trauma Centre. Fracture specific information that was analysed includes: open versus closed, fractured bone(s) and site, initial fracture management, method of diagnosis and soft tissue management. Results. A total of 40 patients were identified, 80% of whom were male (n= 32). The mean age for FRI diagnosis was 54 years (range 18–83 years). In our patient cohort, 10% were immunosuppressed and another 12.5% had a formal diagnosis of Diabetes Mellitus. A diagnosis of acute FRI (i.e. < six weeks from time of injury) was made in 9 patients (22.5%). Chronic FRI was noted in 25 patients (62.5%). There was equal incidence of FRI in patients with closed fractures and open fractures (42.5%). Tibia and fibula fractures were most common (87.5%, n=35). Regardless of fractured bone(s), the more distal the fracture the higher the incidence of FRI (60% distal versus 12.5% proximal). Gram-positive cocci were the most commonly identified pathogens, identified in 25% of patients. Five patients underwent free flap reconstruction, two patients received pedicled muscle flaps and another two patients received split thickness skin grafts. Conclusions. The diagnosis of FRI can be confirmed through the presence of a combination of confirmatory and suggestive criteria. We advocate a staged approach in the management of FRI with radical wound excision and temporary coverage followed by definitive soft tissue reconstruction

Introduction. Open fragility ankle fractures involve complex decision making. There is no consensus on the method of surgical management. Our aim in this study was to analyse current management of these patients in a major trauma centre (MTC). Materials & Methods. This cohort study evaluates the management of geriatric (≥65years) open ankle fractures in a MTC (November 2020–November 2022). The method, timing(s) and personnel involved in surgical care were assessed. Weightbearing status over the treatment course was monitored. Patient frailty was measured using the clinical frailty score (CFS). Results. There were 35 patients, mean age 77 years (range 65–97 years), 86% female. Mean length of admission in the MTC was 26.4 days (range 3–78). Most (94%) had a low-energy mechanism of injury. Only 57% of patients underwent one-stage surgery (ORIF n=15, hindfoot nail n=1, external frame n=4) with 45% being permitted to fully weightbear (FWB). Eleven (31.4%) underwent two-stage surgery (external fixator; ORIF), with 18% permitted to FWB. Of those patients with pre-injury mobility, 12 (66%) patients were able to FWB following definitive fixation. Delay in weightbearing ranged from 2–8weeks post-operatively. Seven patients (20%) underwent an initial Orthoplastic wound debridement. Ten patients (28.6%) required plastic surgery input (split-skin grafts n=9, local or free flaps n=3), whereby four patients (40%) underwent one stage Orthoplastic surgery. Eighteen (51.4%) patients had a CFS ≥5. Patients with a CFS of ≥7 had 60% 90-day mortality. Only 17% patients had orthogeriatrician input during admission. Conclusions. These patients have high frailty scores, utilise a relatively large portion of resources with multiple theatre attendances and protracted ward occupancy in an MTC. Early FWB status needs to be the goal of treatment, ideally in a single-staged procedure. Poor access to orthogeriatric care for these frail patients may represent healthcare inequality

Aim. To classify Fracture-related Infection (FRI) allowing comparison of clinical studies and to guide decision-making around the main surgical treatment concepts. Method. An international group of FRI experts met in Lisbon, June 2022 and proposed a new FRI classification. A core group met during the EBJIS Meeting in Graz, 2022 and on-line, to determine the preconditions, purpose, primary factors for inclusion, format and the detailed description of the elements of an FRI Classification. Results. Historically, FRI was classified by time from injury alone (early, delayed or late). Time produces pathophysiological changes which affect the bone, the soft-tissues and the patient general health, over a continuum. No definitive cut-off is therefore possible. Also, in several studies, time was not identified as an independent predictor of outcome. The most important primary factors were characteristics of the fracture (F), relevant systemic co-morbidities of the patient (R) and impairment of the soft-tissue envelope (I). These factors determine FRI severity, choice of treatment method and are predictors of outcome. For the fracture (F), the state of healing, the potential for bone healing and the presence or absence of a bone defect are critical factors. Co-morbidities are listed and the degree of end-organ damage is important (R). The ability to close the wound directly or the need for soft tissue reconstruction determines the impairment of the soft tissue component (I). Hence the FRI Classification was designed. The final proposal of the FRI Classification is presented here. The new classification has five stages; from simple cases of infected healed fractures, in healthy individuals with good soft tissues (Stage 1), through unhealed fractures with variable potential for bone healing (Stages 2, 3 or 4) to Stage 5, with no limb-sparing or reconstructive options. For instance, the need for a free flap (I4), over a well-healed fracture (F1), in a patient with 2 co-morbidities (R2) gives a classification of F1R2I4 for that patient. Conclusions. This novel approach to FRI classification builds on previous work in osteomyelitis, PJI and chronic medical conditions. It focusses attention on the elements of the disease which need treatment. It now requires validation in large patient cohorts. On behalf of the FRI Classification Consensus Group

Aim. This retrospective study evaluated the outcome of treatment for unhealed fracture-related infections (FRI). Methods. We identified a consecutive, single-centre cohort of patients having treatment for an FRI Consensus confirmed FRI. All fractures were unhealed at the time of treatment. Patients were followed up for at least one year. Successful outcome was a healed fracture without recurrent infection. Lack of union, persistent infection and/or unplanned reoperation defined failure. Results. Demographics: 183 patients (184 FRIs) with mean age 52.1 years (range 17-96) were treated and followed up for a mean of 2.8 years (range 1-9.4). Mean duration of FRI was 1.1 years with 65 (35.5 %) presenting within 6 months of injury. 118 patients had established infected non-union. FRI was most frequent in the tibia (74), femur (48) and humerus (24). 171 patients were BACH Complex. 75.5% of FRIs were culture positive, with Staph. aureus being the most frequent organism. Polymicrobial infection and Gram negative cultures were common (25.5% and 33.6%). Treatment: 98.3% of surgeries were performed in one stage with just 3 planned 2-stage procedures (2 endoprosthetic replacements and 1 free fibular flap). No bone graft was used in any surgery and all wounds were closed at first operation. 48 cases (26%) required flap coverage (29 free flaps and 19 local flaps). Local antibiotics were used in 124 cases (67.4%) of primary surgeries. All patients had sampling, debridement, systemic antibiotics and wound closure. 40 (21.7%) had DAIR, 31 (16.8%) had new internal fixation and 105 (57.1%) had external fixation (including 79 Ilizarov fixators). Outcomes: After primary surgery, 84.6% of all patients were infection-free and 77.2% had united. After further surgery, 98.8% were infection-free and 98.1% had united. External fixation techniques achieved infection eradication in 89.1% compared to 71.7% with any internal fixation (p=0.005). Primary internal fixation achieved union in 81.7% compared to 74.3% with external fixation (p=0.27). Secondary surgery after external fixation was mainly docking site fixation. Conclusion. Unhealed FRIs present a difficult challenge for treatment. This large series demonstrated that single-stage treatment, without bone grafting, gave acceptable results with few reoperations. Primary external fixation gave more certainty of infection eradication but required more reoperations to secure union. However, this difference in reoperation was not statistically significant. We strongly advocate managing these patients with a multidisciplinary team which can treat all aspects of the condition

Aim. Soft tissue defects of the lower leg can be closed - following the reconstructive ladder - with a pediculated fasciocutaneous suralis flap, but a free flap is gold standard in most of the cases. Aim of the study was to evaluate complications, risk factors for failure and the reasonableness of this procedure. Method. 91 patients (92 flaps, 70 males, 21 females) with a mean Age of 55 years (16 to 87) were included in the study. The patients had mean four surgical procedures before the flap, the follow-up was mean 407 days. 70 patients were classified ASA I or ASA II. Results. There were many complications, mostly wound healing Problems or hematoma. Only 40% of the patients received no Revision surgery, 71% of the flaps reached healing with Maximum two revisions (22% with one, 9% with two revisions, respectively). Necrectomy and new meshgraft were main reasons for Revision. Long term complications were swelling or disturbance of sensitivity. We lost seven flaps, eight free flaps were necessary. Three amputations were performed, but only one because of the lost flap. Conclusions. All patients with lost flaps showed relevant comorbidities. 71% of the flaps healed with Maximum two revisions and the overall flap loss rate was 6%. The Advantages of this flap are short surgery time without the need of a microvascular anastomosis and a relatively simple surgical technique. The flap loss rate of 6% seems to be acceptable and, however, the flap is a good Option and an important step of the reconstructive ladder for soft tissue defect closure of the lower leg

Traditional teaching, and indeed the impression from the BOA BAPS working party report on open tibial fractures, suggests that soft tissue cover of the distal third of the leg will often need a free flap. However, more recently with the introduction of propeller flaps by Quaba, and the reintroduction of the concept of Ponten's nerve oriented flaps with the reverse sural artery flap, the role of free tissue transfer comes into question. The attraction of local flaps for distal third fractures is the reduced operating time, reduced morbidity of donor site, versatility and reliability. However, detractors would argue that muscle enhances bone union and reduces local infection. Previous reviews of lower limb soft tissue cover look at all areas of the leg. This series of 30 (14 free and 16 local flaps) cases looks exclusively at the distal third fractures, compares the complication rate of free versus local flaps and looks at the change in approach to distal third fractures with the more recently described fascio-cutaneous flaps. Our results challenge the conventional teaching and indicate that fasciocutaneous flaps can play a more active role in distal third fractures. Our study shows that the local flaps are a valuable alternative to free flaps for managing soft tissue defects in distal third fractures of tibia especially in smaller wound size and low energy fractures. The advantages are lesser operating time, reliability, versatility, lesser wound complication and osteomyelitis incidence, earlier flap cover and lesser post op morbidity leading to shorter hospital stay. The free flaps on balance are probably better with larger soft tissue defects and with more severe limb injury. This supports the use of fascio-cutaneous flaps in distal third tibial fractures

The literature states pre-operative angiography of open tibial fractures (OTFs) should only be considered if abnormal pedal pulses are present. Aim. Does pre-operative angiography of OTFs benefit patient management?. Method. 43 patients were admitted with OTFs to Charing Cross Hospital, London between 3/2004 and 6/2005. Pedal pulses were documented and routine pre-operative angiography performed following primary surgical debridement. At definitive operation, data was collected prospectively assessing vasculature and the microsurgical findings. All patients underwent free flap reconstruction or amputation. Comparison was made with angiographic findings and whether surgical management had been affected. Retrospective audit of all angiograms was performed by a consultant radiologist establishing the sensitivity/specificity. Results. Patients' mean age was 36 (18-86) with ratio 31M:12F. 40 patients had normal pedal pulses; 3 abnormal. 26 had normal angiography and 17 abnormal. 13/17 were due to injury, 2 anatomical variants and 2 atherosclerotic disease. Commonest vessel damaged was the anterior tibial (AT) n=8. Posterior tibial artery (PT) was not damaged alone but with AT n=3. AT damaged alone n=4 and AT with peroneal n=1. Popliteal artery was damaged alone n=1. 4/13 vessels with injury-induced damage required adjustment of pedicle anastomosis along with 1 from the variant group and 1 from the atherosclerotic group. Therefore 6/43 (14%) patients had surgery adjusted and the findings detected angiographically were confirmed clinically. 40 free flaps were performed and 3 amputations. All free flaps survived. 2 cases had abnormal vasculature not detected by angiogram (thrombosed venae commitans n=1 and distal PT ligated n=1). Audit of the angiograms when compared to clinical findings revealed sensitivity 90% and specificity 100%. Conclusion. A six times increase in vessel damage was discovered after angiography compared with clinical assessment alone. The findings significantly affected surgical practice. A high degree of sensitivity/specificity was seen with angiography. The authors advocate routine angiography for all OTFs

Aim. Fracture-related infection (FRI) is a severe post-traumatic complication which can be accompanied with a soft-tissue defect or an avital soft-tissue envelope. In these cases, a thoroughly planned orthoplastic approach is imperative since a vital soft-tissue envelope is mandatory to achieve fracture union and infection eradication. The aim of our study was to analyse plastic surgical aspects in the management of FRIs, including the type and outcome of soft-tissue reconstruction (STR), and to investigate the long-term outcome of FRI after STR. Method. Patients with a lower leg FRI requiring STR that were treated from 2010 to 2018 at our center were included in this retrospective analysis. STR involved the use of local, pedicled and free flaps. The primary outcome was the success rate of STR, and the secondary outcome was long-term fracture consolidation and cure of infection. Results. Overall, 145 patients with lower leg FRI were identified, of whom 58 (40%) received STR. Muscle flaps were applied in 38, fascio-cutaneous flaps in 19 and a composite osteo-cutaneous flap in one case. All patients underwent successful STR (primary STR in 51/58 patients, 7/58 patients needed secondary STR). A high Charlson Comorbidity Index Score was a significant risk factor for flap failure (p=0.011). Patients with free-flap STR developed significantly more severe complications and needed more surgical interventions (Clavien-Dindo ≥IIIa; p=0.001). Out of the 43 patients that completed long-term follow-up (mean 24 months), fracture consolidation was achieved in 32 and infection eradication in 31. Polymicrobial infection was a significant risk factor for fracture non-union (p=0.002). American Society of Anesthesiologists (ASA) classification of 3 or higher (p=0.040) was a risk factor for persistence or recurrence of infection. Conclusions. In our population, 58/145 patients with FRI required STR. STR was successful in all patients eventually, in 7/58 patients secondary STR was necessary. Therefore, STR should be sought even if primary STR fails. Despite successful STR, the long-term composite outcome showed a high rate of failed fracture consolidation and failed eradication of infection, which was independent of primary STR failure

Introduction and aims. We present a series of patients who have had secondary reconstruction of war injuries to the upper and lower limbs, sustained during the Iraq and Afghanistan conflicts. Material and Methods. All patients were seen at the combined Peripheral Nerve Injuries Clinic at the Defence Medical Centre for Rehabilitation, Headley Court. All surgery was performed at Odstock Hospital. Procedures include scar excision and neurolysis (all patients), release of scar contractures, tenolysis, tendon transfers, revision nerve grafts, excision of neuroma, and soft tissue reconstruction using pedicled or free flaps. Results. 24 patients have been treated at the time of submission. We have used 13 free flaps (1 free groin flap, 9 anterolateral thigh, 3 parascapular, with 4 as through-flow flaps) and 1 pedicled groin flap, with no flap losses. There were 6 amputation stump revisions (1 above elbow, 5 below knee). The majority (n=23) have had nerve recovery distal to the level of injury following revision surgery. Conclusions. Nerve repairs recover following neurolysis (and revision nerve graft if necessary) with provision of good soft tissue cover. Release of scar contractures with flap cover allows healing of chronic wounds and permits mobilisation of joints. Thin fascio-cutaneous flaps provide good contour and can be elevated more easily than skin grafted muscle flaps for secondary surgery. Free or regional flaps are preferable to local flaps in high energy-transfer military wounds. Immediate complex reconstruction is not always appropriate in multiply-injured patients

Aim. This study aimed to define the increased costs incurred by a return to theatre for cases requiring free tissue transfer for surgical treatment of chronic osteomyelitis. We hypothesised that there would be a significantly greater cost when patients required re-exploration of the free flap. Method. We retrospectively analysed the costs of a consecutive series of sixty patient episodes treated at the Bone Infection Unit in Oxford from 2012 to 2015. Treatment involved excision of osteomyelitis with free tissue transfer for immediate soft tissue cover. We compared the costs of uncomplicated cases with those who returned to theatre and determined the profit/loss for the hospital from remuneration through the UK National Health Service Tariff Structure. Results. Hospital income according to UK HRG tariff was compared to the actual cost of treatment and these 60 cases were significantly underfunded overall (P < 0.005). In just 1 case, the cost to the hospital was completely covered by tariff. Six patients (10%) returned to theatre for urgent flap re-exploration with five flaps salvaged and one failed, requiring another free flap reconstruction (1.7%). These six patient episodes had a significantly higher mean cost compared to the uncomplicated cases. The average financial loss to the hospital for patients who did return to theatre was £18992 (range £8103 to £48380) and in those who did not was £9600 (range – £600 to £23717). The case requiring further free tissue transfer cost a total of £74158, £48380 more than the hospital was paid: the most extreme discrepancy. The overall loss for this group of 60 patients was £590766. Conclusions. Surgery for chronic osteomyelitis is multidisciplinary, complex and therefore expensive. However, this study demonstrates that the hospital currently makes a financial loss on almost all patients but especially if flap complications occur. This study has implications for the long term viability of specialist units treating this important disease
