TKA (Total Knee Arthroplasty) is a successful operation. Soft tissue problems with TKA are difficult to treat. Flap surgery is successful in treating this problem and salvaging the prostheses. We present results of flap surgery for complicated TKAs over a ten year period, performed by a single surgeon. Between 1996 and 2005, 31 patients (32 knees) underwent flap surgeries for TKAs. Four of these procedures were done prophylactically in patients with previous knee surgeries. Gastrocnemius, medial fasciocutaneous and anterior compartment flaps were used either solely or in combination based on the size of the defect. The data was collected retrospectively from case-notes and correspondence from the treating orthopaedic surgeons. All the knees included in the study had a minimum follow up of 6 months. The patients were aged between 50 and 94 years. Indication for primary TKA was osteoarthritis in 26 patients and rheumatoid arthritis in 5. The index orthopaedic surgery was a primary knee arthroplasty in 14 and revision in 13. The average duration between the TKA and flap surgery was 11 weeks (range 1 – 52). Gastrocnemius was the most commonly used local flap (17 cases). Anterior compartment flap was used in 5 cases and in the rest combination of flaps was used. Coagulase -ve Staph. aureus was the most commonly isolated organism from the perioperative wound swabs. Successful soft tissue cover was achieved in 29 of 32 knees (92%). Overall, TKA was salvaged in 23 of 32 knees (72%) and 3 knees (9.7%) underwent arthrodesis. Three (9.7%) patients had above knee amputation, two of these had post op MRSA infection. We could not use a functional knee scoring system due to inadequate information available. We conclude local flap surgery is a viable and successful procedure for providing soft tissue cover for complicated TKAs with good results

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

Aims. Calcaneal osteomyelitis remains a difficult condition to treat with high rates of recurrence and below-knee amputation, particularly in the presence of severe soft-tissue destruction. This study assesses the outcomes of single-stage orthoplastic surgical treatment of calcaneal osteomyelitis with large soft-tissue defects. Methods. A retrospective review was performed of all patients who underwent combined single-stage orthoplastic treatment of calcaneal osteomyelitis (01/2008 to 12/2022). Primary outcome measures were osteomyelitis recurrence and below-knee amputation (BKA). Secondary outcome measures included flap failure, operating time, complications, and length of stay. Results. A total of 30 patients (14 female, 16 male; mean age 53.7 years (95% CI 48.0 to 59.5)) underwent combined orthoplastic surgical treatment for BACH “complex” calcaneal osteomyelitis with a median follow-up of 31 months (IQR 11.75 to 49.25). Of these, 19 received a local flap and 11 received a free flap. The most common causes were fracture-related infection (n = 12; 40%) and ulceration (n = 10; 33%); 21 patients (70%) had already undergone at least one operation elsewhere. Osteomyelitis was eradicated in 23 patients (77%). There were seven patients who developed recurrent osteomyelitis (23%), all in the local flap group. One patient required a BKA. Univariate analysis revealed that local flap reconstruction (OR 13.5 (95% CI 0.7 to 269.7); p = 0.029) and peripheral vascular disease (OR 16.5 (95% CI 1.35 to 203.1); p = 0.008) were associated with increased risk of recurrence. Free flap reconstruction took significantly longer intraoperatively than local flaps (mean 481 minutes (408 to 554) vs mean 168 minutes (119 to 216); p < 0.001), but without significant differences in length of stay or frequency of outpatient appointments. Conclusion. In our study involving 30 patients, single-stage orthoplastic management was associated with 77% (n = 23) eradication of infection and only one amputation in this complex and comorbid patient group. Risk factors for failure were peripheral vascular disease and local flap reconstruction. While good outcomes can be achieved, this treatment requires high levels of inpatient and outpatient care.

Introduction and aims: Soft tissue defects after total knee arthroplasty (TKA) are difficult problems to treat. Flap surgery has been successful in salvaging the prostheses. We present results of flap surgery for exposed TKAs over a 10 year period performed by single surgeon. Material and Methods: Between 1996 and 2005, 31 patients (32 knees) underwent flap surgeries for TKAs. Four of these procedures were done prophylactically in patients with previous knee surgeries. Gastrocnemius, medial fasciocutaneous and anterior compartment flaps were used either solely or in combination based on the size of the defect. The data was collected retrospectively from case-notes and correspondence from the treating orthopaedic surgeons. Results: The patients were aged between 50 and 94 years. Indication for primary TKA was osteoarthritis in 25 patients and rheumatoid arthritis in 5. Coagulase negative Staph. aureus was the most commonly isolated organism. In patients using steroids, 4 of 6 (71.4%) knees had good or satisfactory outcome compared to 22 of 24 (91.7%) knees in patients not on steroids. Smoking did not influence the outcome of flap surgery . The average duration between the TKA and flap surgery was 11 weeks (range 1 – 52). Successful soft tissue cover was achieved in 30 of 32 knees (94%). Overall, TKA was salvaged in 20 of 28 knees (71.4%) knees, 3 knees (9.7%) underwent arthrodesis and above knee amputation was performed in 4 (12.4%). The information gathered from case notes and orthopaedic surgeons was insufficient to use a knee score for evaluating the functional outcome of the procedure. Conclusion: Local flap surgery for providing soft tissue cover for exposed TKA is a viable and successful procedure with good results

Background. 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. Aim. Assess 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

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. 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

Sternoclavicular joint infections are uncommon but severe and complex condition usually in medically complex and compromised hosts. These infections are challenging to treat with risks of infection extending into the mediastinal structures and surgical drainage is often faced with problems of multiple unplanned returns to theatre, chronic non-healing wounds that turn into sinus and the risk of significant clinical escalation and death. Percutaneous aspirations or small incision drainage often provide inadequate drainage and failed control of infection, while open drainage and washout require multidisciplinary support, due to the close proximity of the mediastinal structures and the great vessels as well as failure to heal the wounds and creation of chronic wound or sinus. We present our series of 8 cases over 6 years where we used the plan of open debridement of the Sternoclavicular joint with medial end of clavicle excision to allow adequate drainage. The surgical incision was not closed primarily, and a suction vacuum dressing was applied until the infection was contained on clinical and laboratory parameters. After the infection was deemed contained, the surgical incision was closed by local muscle flap by transferring the medial upper sternal head of the Pectoralis Major muscle to fill in the sternoclavicular joint defect. This technique provided a consistent and reliable way to overcome the infection and have the wound definitively closed that required no secondary procedures after the flap surgery and no recurrence of infections so far. We suggest that open and adequate drainage of Sternoclavicular joint staged with vacuum dressing followed by pectoralis major local flap is a reliable technique for achieving control of infection and wound closure for these challenging infections

Aims. Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest. Methods. A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS). Results. In the first stage, there were 36 respondents to the survey, with over 70% stating their unit treats more than 20 such cases per year. There was a 50:50 split regarding if the timing of surgery should be within 36 hours, as per the hip fracture guidelines, or 72 hours, as per the open fracture guidelines. Overall, 75% would attempt primary wound closure and 25% would utilize a local flap. There was no orthopaedic agreement on fixation, and 75% would permit weightbearing immediately. In the second stage, performed at the BLRS meeting, experts discussed the survey results and agreed upon a consensus for the management of open elderly ankle fractures. Conclusion. A mutually agreed consensus from the expert panel was reached to enable the best practice for the management of patients with frailty with an open ankle fracture: 1) all units managing lower limb fragility fractures should do so through a cohorted multidisciplinary pathway. This pathway should follow the standards laid down in the "care of the older or frail orthopaedic trauma patient" British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guideline. These patients have low bone density, and we should recommend full falls and bone health assessment; 2) all open lower limb fragility fractures should be treated in a single stage within 24 hours of injury if possible; 3) all patients with fragility fractures of the lower limb should be considered for mobilisation on the day following surgery; 4) all patients with lower limb open fragility fractures should be considered for tissue sparing, with judicious debridement as a default; 5) all patients with open lower limb fragility fractures should be managed by a consultant plastic surgeon with primary closure wherever possible; and 6) the method of fixation must allow for immediate unrestricted weightbearing.

Aims. Reconstruction after osteoarticular resection of the proximal ulna for tumours is technically difficult and little has been written about the options that are available. We report a series of four patients who underwent radial neck to humeral trochlea transposition arthroplasty following proximal ulnar osteoarticular resection. Methods. Between July 2020 and July 2022, four patients with primary bone tumours of the ulna underwent radial neck to humeral trochlea transposition arthroplasty. Their mean age was 28 years (12 to 41). The functional outcome was assessed using the range of motion (ROM) of the elbow, rotation of the forearm and stability of the elbow, the Musculoskeletal Tumor Society score (MSTS), and the nine-item abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH-9) score. Results. All patients were available for follow-up at a mean of 33 months (25 to 43) and were disease-free. The mean flexion arc was 0° to 105°. Three patients had complications. One had neuropraxia of the ulnar nerve. The symptoms resolved after three months. In one patient, the screw used for fixation of the triceps tendon became exposed and was removed, six months postoperatively. One patient with wound dehiscence required a local flap for soft-tissue cover, four months postoperatively. At a mean follow-up of 33 months (25 to 43), the mean flexion arc was 0° to 105°. All patients had full supination (85°) but none had any pronation. The mean MSTS score was 23.5 (23 to 24) and mean QuickDASH-9 score was 26.13 (16.5 to 35.75). Three patients had varus-valgus instability on examination, although only one had a sense of instability while working. Conclusion. Radial neck to humeral trochlea transposition offers a satisfactory and cost-effective biological reconstructive option after osteoarticular resection of the proximal ulna, in the short term. It provides good elbow function and, being a biological reconstruction option using native bone, is likely to provide long-term stability and durability.

Open limb fractures are typically due to a high energy trauma. Several recent studied have showed treatment's superiority when a multidisciplinary approach is applied. World Health Organization reports that isolate limb traumas have an incidence rate of 11.5/100.000, causing high costs in terms of hospitalization and patient disability. A lack of experience in soft tissue management in orthopaedics and traumatology seems to be the determining factor in the clinical worsening of complex cases. The therapeutic possibilities offered by microsurgery currently permit simultaneous reconstruction of multiple tissues including vessels and nerves, reducing the rate of amputations, recovery time and preventing postoperative complications. Several scoring systems to assess complex limb traumas exist, among them: NISSSA, MESS, AO and Gustilo Anderson. In 2010, a further scoring system was introduced to focus open fractures of all locations: OTA-OFC. Rather than using a single composite score, the OTA-OFC comprises five components grades (skin, arterial, muscle, bone loss and contamination), each rated from mild to severe. The International Consensus Meeting of 2018 on musculoskeletal infections in orthopaedic surgery identified the OTA-OFC score as an efficient catalogue system with interobserver agreement that is comparable or superior to the Gustilo-Anderson classification. OTA-OFC predicts outcomes such as the need for adjuvant treatments or the likelihood of early amputation. An orthoplastic approach reconstruction must pay adequate attention to bone and soft tissue infections management. Concerning bone management: there is little to no difference in terms of infection rates for Gustilo-Anderson types I–II treated by reamed intramedullary nail, circular external fixator, or unreamed intramedullary nail. In Gustilo-Anderson IIIA-B fractures, circular external fixation appears to provide the lowest infection rates when compared to all other fixation methods. Different technique can be used for the reconstruction of bone and soft tissue defects based on each clinical scenario. Open fracture management with fasciocutaneous or muscle flaps shows comparable outcomes in terms of bone healing, soft tissue coverage, acute infection and chronic osteomyelitis prevention. The type of flap should be tailored based on the type of the defect, bone or soft tissue, location, extension and depth of the defect, size of the osseous gap, fracture type, and orthopaedic implantation. Local flaps should be considered in low energy trauma, when skin and soft tissue is not traumatized. In high energy fractures with bone exposure, muscle flaps may offer a more reliable reconstruction with fewer flap failures and lower reoperation rates. On exposed fractures several studies report precise timing for a proper reconstruction. Hence, timing of soft tissue coverage is a critical for length of in-hospital stay and most of the early postoperative complications and outcomes. Early coverage has been associated with higher union rates and lower complications and infection rates compared to those reconstructed after 5-7 days. Furthermore, early reconstruction improves flap survival and reduces surgical complexity, as microsurgical free flap procedures become more challenging with a delay due to an increased pro-thrombotic environment, tissue edema and the increasingly friable vessels. Only those patients presenting to facilities with an actual dedicated orthoplastic trauma service are likely to receive definitive treatment of a severe open fracture with tissue loss within the established parameters of good practice. We conclude that the surgeon's experience appears to be the decisive element in the orthoplastic approach, although reconstructive algorithms may assist in decisional and planification of surgery

Introduction. Osteomyelitis (OM) is a challenging condition to diagnose and treat. The multidisciplinary team (MDT) approach is used in managing complex diseases such as cancer and diabetes. The Hull Regional Bone Infection MDT team was established to provide coordinated care for patients suspected to have OM. This study reviews the orthoplastic treatment and outcomes of patients with non-periprosthetic OM. Materials and Methods. Retrospective review of patients presenting to the MDT team who had orthoplastic intervention with debridement and flap coverage between 1/6/2014 - 30/11/2018. We describe our MDT approach of assessment, planning for surgical intervention and antibiotic protocol. Data was obtained from electronic and paper patient records, and PACS. Results. Twenty-nine patients were identified (75.9% male). Mean age was 52.7 (23–82). Median duration of symptoms at surgery was 10 months (IQR 4.0–34.3). Cierny-Mader (CM) Host Type B. (L). (41.4%), type B. (S). (34.5%), and type B. (S+L). (17.2%). Twenty-four patients (82.8%) were CM anatomical class IV. Twenty-four patients (82.8%) had single-stage surgical treatment. Twenty-one patients received 23 free flaps. Anterolateral thigh flap (9/23) and gracilis muscle flap (7/23) were most commonly used. Tibialis anterior flap was the most commonly used local flap. Stimulan was used in 65.5%. Staphylococcus aureus was seen in 60% of patients. Mean follow-up time was 21 months (1–62). There were 2 (6.9%) OM recurrence. Both patients were CM anatomical class IV. Conclusions. Our study showed that our MDT management of patients with OM can achieve a low recurrence rate despite a high proportion of patients with severe OM. We recommend considering an MDT approach for these complex OM patients

Background. To improve patient pathways we have, in selected patients, begun to acutely apply circular (rather than temporary monolateral) fixators with simultaneous or subsequent soft tissue closure. We present early results. Methods. Adult patients treated using an Ilizarov frame prior to soft tissue management were identified from our Ilizarov database. This data was supplemented by medical record review. Results. 26 cases were identified (22 open fractures (11 IIIA, 11 IIIB), 1 compartment syndrome and 3 infected salvage). All IIIA injuries were closed acutely alongside frame application. In IIIB fractures, 3 were closed following acute shortening, 1 required a local flap and 7 free tissue transfer. Soft tissue reconstruction was simultaneous to frame application in 5 patients, the remainder within 72 hours. In salvage cases, 2 required free and one a local muscle flap, all after frame application. There were no soft tissue cover failures. One patient underwent evacuation of a flap haematoma, there were no other unexpected returns to theatre for soft tissue problems. No patients required adjustment of frame components to allow soft tissue access. Conclusion. This approach appears to simplify treatment, reducing length of stay. We are collecting a matched patient series treated by traditional pathways for comparison

Aim. The reconstruction of bone critical size defects of the tibia is one of the most complex therapeutic challenges in the orthopedic field. This study aims to describe and evaluate our three-staged surgical protocol of reconstruction of infected defects of the tibia emphasizing in limb salvage rate, resolution of infection, functional outcome and patient satisfaction. Method. A retrospective review was performed in all cases of complex infected tibia fracture with combined soft and bone tissue loss treated in a specialized limb reconstruction center between 2010 and 2018. In all cases, a three-stage protocol was performed: 1) Infected-limb damage control with radical debridement, 2) Soft tissue coverage with vascularized or local flap 3) Bone reconstruction procedure. The minimum follow-up required was 12 months after external fixator removal. Results. Twenty-eight patients with a mean age of 42 years were included. The mean soft tissue defect was 91.7 cm2 and the mean bone defect was 5.8 cm. 67.85% of the cases were classified as a type IV B-local osteomyelitis. The median global treatment time was 456 days. The External Fixator Time (EFT) was 419, 284, 235 for bone transport, shortening-lengthening and acute shortening groups respectively. The median Bone Healing Index (BHI) was 1.82 months/cm in bone transport group and 2.15 months/cm in shortening-lengthening group. The limb salvage rate was 92.85%. Infection resolution rate was 96,42%. We achieved bone union in 92,85% of the cases. Regarding ASAMI bone score, 92.8% of the cases were “good-or-excellent”. Two patients underwent a delayed amputation. Eight cases of non-progressive Docking Site (DS) healing were observed. Nineteen non-expected reinterventions were performed. Functional data: the mean VAS score was 1.0. The mean LEFS score was 55.88 (55.88/80). Regarding ASAMI functional score, 78,6% of the cases were “good-or-excellent”. More than 80% of the patients could return to work. 100% of the patients were “very satisfied” or “moderately satisfied” (75% and 25% respectively). Conclusions. Our results demonstrate that our three-stage surgical approach in infected tibial bone defects with soft tissue damage can result in high infection resolution, good functional outcome, good patient satisfaction and an acceptable limb salvage rate despite the large time of treatment and unexpected reinterventions

Aim. Melioidosis is a significant public health problem in endemic regions such as India. Lack of awareness, predominant empiric antibiotic use reducing culture yields, morphotypic variability of cultures and frequent misidentification by automated blood culture systems, pose myriad challenges in diagnosis and treatment. Through this series, we present our experience of Hematogenous Osteomyelitis with Burkholderia pseudomallei. Method. This was a single centre, retrospective, observational study performed at a tertiary case hospital in Mumbai, India from June 2011 to June 2021. Results. The study comprised of 7 cases (6:1, M: F). Mean age was 53.7 years (5 to 75). All had an underlying co- morbidity or were immunosuppressed. 3 patients were misidentified by automated systems prior to presentation (e coli, burkholderia cepacieae, acinetobacter). Most common site of infection was femur (n= 3), followed by tibia and foot and ankle (n= 2, each). One had disseminated meliodosis involving the spleen, lymph nodes, pulmonary) in addition to involvement of bilateral feet and ankles. B. pseudomallei was identified in all following surgical debridement at our institute. Each patient underwent mean 2 procedures. 3 needed local rotation flap surgeries for wound cover. All were treated with ceftazidime along with trimethoprim- sulfamethoxazole (TMP- SMX) during the 6 week induction phase. TMP- SMX was continued for a further 6 months in the consolidation phase. All patients had infection remission at a mean 19.3 months follow up. There were no mortalities in our series. Conclusions. Clinically Burkholderia infections mimic other pyogenic infections, Gram-negative sepsis, tuberculosis and has been referred to as the “remarkable imitator” and the “mimicker of maladies”. Diabetes and alcoholism are risk factors. The need for diagnosing this entity is due to the fact that the septicemic form has a mortality rate that exceeds 90%. Melioidosis is frequently misidentified. A high clinical suspicion, communication with microbiologist, knowledge about the biochemical, cultural and phenotypic susceptibility patterns may help in optimising diagnosis. Adequate debridement coupled with targeted prolonged antibiotics help achieve good outcomes

Aims. Following the introduction of national standards in 2009, most major paediatric trauma is now triaged to specialist units offering combined orthopaedic and plastic surgical expertise. We investigated the management of open tibia fractures at a paediatric trauma centre, primarily reporting the risk of infection and rate of union. Patients and Methods. A retrospective review was performed on 61 children who between 2007 and 2015 presented with an open tibia fracture. Their mean age was nine years (2 to 16) and the median follow-up was ten months (interquartile range 5 to 18). Management involved IV antibiotics, early debridement and combined treatment of the skeletal and soft-tissue injuries in line with standards proposed by the British Orthopaedic Association. Results. There were 36 diaphyseal fractures and 25 distal tibial fractures. Of the distal fractures, eight involved the physis. Motor vehicle collisions accounted for two thirds of the injuries and 38 patients (62%) arrived outside of normal working hours. The initial method of stabilisation comprised: casting in nine cases (15%); elastic nailing in 19 (31%); Kirschner (K)-wiring in 13 (21%); intramedullary nailing in one (2%); open reduction and plate fixation in four (7%); and external fixation in 15 (25%). Wound management comprised: primary wound closure in 24 (39%), delayed primary closure in 11 (18%), split skin graft (SSG) in eight (13%), local flap with SSG in 17 (28%) and a free flap in one. A total of 43 fractures (70%) were Gustilo-Anderson grade III. There were four superficial (6.6%) and three (4.9%) deep infections. Two deep infections occurred following open reduction and plate fixation and the third after K-wire fixation of a distal fracture. No patient who underwent primary wound closure developed an infection. All the fractures united, although nine patients required revision of a mono-lateral to circular frame for delayed union (two) or for altered alignment or length (seven). The mean time to union was two weeks longer in diaphyseal fractures than in distal fractures (13 weeks versus 10.8 weeks, p = 0.016). Children aged > 12 years had a significantly longer time to union than those aged < 12 years (16.3 weeks versus 11.4 weeks, p = 0.045). The length of stay in hospital for patients with a Gustilo-Anderson grade IIIB fracture was twice as long as for less severe injuries. . Conclusion. Fractures in children heal better than those in adults. Based on our experience of deep infection we discourage the use of internal fixation with a plate for open tibial fractures in children. We advocate aggressive initial wound debridement in theatre with early definitive combined orthopaedic and plastic surgery in order to obtain skeletal stabilisation and soft-tissue cover.

We evaluated the effectiveness of local and free flap cover done at revision surgery for infected endoprosthetic replacement (EPR) in achieving ultimate control of infection. Methods: Ten patients needed plastic surgical input in the form of flap cover at the time of revision surgery for infective endoprosthetic failure between March 1999 and March 2005. The revision of EPR itself was undertaken in 2 stages. The 1st stage involved removal of the endoprosthesis, insertion of antibiotic spacer and flap cover. After achieving adequate control of infection, 2nd stage revision was carried out, in which the spacer was exchanged for an endoprosthesis. Results: Average age at time of flap surgery was 29 years (range 14 – 58 years). Average follow up was 23 months (3 to 72 months) for patients who remained free of infection and 19 months (5 to 52 months) for those who underwent amputation. 9 out of 10 patients underwent some form of muscle flap (6 free LD flaps, 2 gastrocnemius flaps and 1 pedicled LD flap). Infection was adequately controlled in 5 out of 6 patients in free flap group. Out of 4 patients who underwent local flaps, 2 ended up having amputation. Conclusion: Reconstructive surgery in the form of flap cover has an important role in limb salvage in patients with endoprosthetic failure due to infection. The aim of such surgery should be to provide as much new vascularized tissue over the dependent portions with sinuses and areas of radiotherapy with scarring. Results of cover by a broad flat musculocutaneous flaps seem to be better in comparison to local flaps

Aims. To evaluate the place of the massive prostheses in the most complex periprosthetic infections cases (PJis). Method. Between 2011 and 2017, 516 hip and knee revisions for periprosthetic infections had been performed in our hospital by the same senior surgeon. We report a prospective series of 58 patients treated between 2011 and the end of 2017. 26 males and 32 females with on average 69,4 years old (38–86). Infection involved TKA in 39 cases (26 TKA revisions, 11 primary TKA), THA in 18 cases (10 revisions, 7 primary THA), a femoral pseudoarthrosis with posttraumatic gonarthrosis in one case and a septic humeral pseudoarthrosis in one case. We used one stage procedures in 38 cases (14 hips, 23 knees, 1 shoulder) and 20 two stages surgeries (16 knees and 4 hips). Additional technics used with massive prostheses, all for TKA PJis: 4 massive extensor systemallografts performed two times in a one stage procedure, two local flaps (medial gastronecmienmuscle). Two perioperative hyperbaric procedures used to limit the risks of wound complications. Results. The average follow-up is 38 months (12–62 months). The rate of sucess to treat the infection at this follow-up is 89,7 %. We report our feedback of the different massive components uses and the qualities/defaults we noted. The most frequent complication was skin events like wound swelling and delayed cicatrisations in 13 cases. 3 cases of one stages needed a complementary debridement in the three weeks after the surgery with always a good local and infectious evolution. This series report 5 failures of two stages TKA revisions. In 4 cases, the initial local soft tissues conditions were compromised. Conclusions. The use of massive prostheses to treat PJIs is a good option for the complex cases. It can be a good alternative of knee arthrodesis. These components must be used, preferentially for oldest patients, in cases of extreme bone loss or extensed osteitis to secure the bone debridement and the quality of the reconstruction. In our series, the one stage procedure is a validated option even by using complementary technics as bone allografts, extensor system allografts or flaps. The two stages procedure is a secondary option, particularly when softtissues status is compromised before or after the debridement, and mostly for the knees

This study aimed to ascertain whether stabilising only the AITFL is enough to prevent talar shift, and to test a simple, novel technique to reconstruct the AITFL. Twelve cadavers were used. Talar shift was measured following: 1- no ligaments cut; 2- entire deltoid ligament division; 3- group A (5 specimens) PITFL cut whilst group B (7 specimens) AITFL cut; 4- group A had AITFL divided whilst group B had the PITFL cut. Reconstruction of the AITFL was performed using part of the superior extensor retinaculum as a local flap. Measurement of talar shift was then repeated. With no ligaments divided, mean talar shift was 0.8mm for group A and 0.7mm for group B. When the deltoid ligament was divided, mean talar shift for group A was 4.8mm compared to 4.7mm in group B (P=1.00). The mean shift in group A after PITFL division was 6.0mm, increasing the talar shift by an average of 1.2mm. In group B after AITFL division mean talar shift was 8.3mm (P=0.06), increasing talar shift by an average of 3.6 mm. After division of the second tibiofibular ligament, mean talar shift in group A measured 10.0mm and in group B was 10.9mm(P=0.29). Three times more talar shift occurred after the AIFTL was divided compared to the PITFL. Repairing just the PITFL (for example by fixation of the posterior malleolus avulsion fracture) may not adequately prevent talar shift while reconstruction of the AITFL potentially restores ankle stability
