Introduction:. TTC fusion for the salvage of failed TARs with significant bone loss using a hindfoot nail and femoral head allograft has been reported in a number of small series. We present our experience of this procedure. Method:. Review of the theatre records from 2006 to July 2011 identified twenty four cases using this technique. The case notes and imaging were retrospectively reviewed. Results:. Overall eighteen of the twenty four cases had achieved union (mean time 18.8 months). Of this number two had under gone a revision hindfoot nailing and another case needed revision with a circular frame. A further three cases required dynamisation to unite. There were five non unions and one loss to follow up (at two months). Complications included one deep infection (non union) and one case with chronic regional pain syndrome. Metalwork complications included five nail fractures and five cases that required prominent screw removal. Conclusions:. This is the largest series reported using this technique for the salvage of failed TARs with significant bone loss. Other smaller series using this technique have reported union rates around fifty per cent. The time to union is long and half of these cases required further procedures during this course. This is important to reflect when consenting the patient for this type of surgery

Introduction:. This study presents a series of 64 patients undergoing tibio-talo-calcaneal (TTC) fusions with a hindfoot nail to compare the times to union and complications comparing use of allograft with no allograft. Methods:. We conducted a retrospective review of patients undergoing a TTC fusion with a hindfoot nail from a period from 2010 to 2013. A total of 64 patients were collated which were performed by 3 surgeons across two centres. We reviewed the medical notes to determine the complications associated with the procedures and the radiographs to assess the time to clinical/radiological union. A comparison between the patients who had undergone a TTC fusion with allograft versus patients who had not received any allograft was made. Results:. Within our group, n = 15 (23%) patients had allograft utilised and n = 49 (77%) patients underwent TTC fusion without allograft. Within the allograft group, the mean time to union was longer and the complications included deep infection n = 2 (13%), prominent metalwork n = 2(13%). The mean number of operations per patient was 1.33. Within the group not receiving allograft, the mean time to union was shorter than that of allograft group and the complications noted were fracture n = 1 (2%), prominent metal work n = 1 (2%) & non-union n = 5 (10%), with the mean number of operations per patient being 1.18. Conclusions:. In our study we have found that patients undergoing TTC fusion with bulk allograft had longer times to union with a higher rate of complication p=0.22 and increased number of surgeries. When managing patients with bone loss, the benefits of utilising allograft to maintain limb length versus the longer time to union and increased rate of secondary surgeries needs to be balanced, but appears justified in our series

Ankle fractures represent the third most common fragility fracture seen in elderly patients following hip and distal radius fractures. Non-operative management of these see complication rates as high as 70%. Open reduction and internal fixation (ORIF) has complication rates of up to 40%. With either option, patients tend to be managed with a non-weight bearing period of six weeks or longer. An alternative is the use of a tibiotalocalcaneal (TTC) nail. This provides a percutaneous treatment that enables the patient to mobilise immediately. This case-series explores the efficacy of this device in a broad population, including the highly comorbid and cognitively impaired.

We reviewed patients treated with TTC nail for acute ankle fractures between 2019 and 2022. Baseline and surgical data were collected. Clinical records were reviewed to record any post-operative complication, and post-operative mobility status and domicile. 24 patients had their ankle fracture managed with TTC nailing. No intra-operative complications were noted. There were six (27%) post-operative complications; four patients had loosening of a distal locking screw, one significant wound infection necessitating exchange of nail, and one pressure area from an underlying displaced fracture fragment. All except three patients returned to their previous domicile. Just over two thirds of patients returned to their baseline level of mobility.

This case-series is one of the largest and is also one of the first to include cognitively impaired patients. Our results are consistent with other case-series with a favourable complication rate when compared with ORIF in similar patient groups. The use of a TTC nail in the context of acute, geriatric ankle trauma is a simple and effective treatment modality. This series shows acceptable complication rates and the majority of patients are able to return to their baseline level of mobility and domicile.

Introduction

With an aging population, the prevalence of fragility ankle fractures is rising. The surgical management of these injuries is challenging and associated with high rates of complications. The incidence of fragility ankle fractures is currently estimated to be around 150 per 100,000 people annually and is anticipated to rise to around 269 per 100,000 by 2030. The aim of surgery is to restore mobility, preserve function and to prevent complications related to non-weight-bearing and the application of hind foot nail (HFN) seems to provide these advantages. This systematic review aims to investigate the role of HFN in the treatment of fragility ankle fractures. We aim to review the available evidence published on the functional recovery observed in patients following treatment with HFN and the observed complications in the literature.

Ankle osteomyelitis after open pilon-fractures remain one of the most challenging scenarios. Ankle-fusion using an external frame is a classical option but in some cases of non-compliance patients could be not ideal. The purpose of this report was to evaluate our results using a new staged salvage protocol in cases where an external-frame arthrodesis is not recommended due to the issue of a non-compliance patient. During the first stage we resect all the infected tissues and an antibiotic-loaded cement spacer is used to obliterate the dead space, to reach some kind of stability and to achieve a high concentration of local antibiotic. A free or keystone flap is used if needed and a posterior splint is placed. After a course of targeted systemic antibiotics the second stage is schedule. During the second stage after the spacer removal, a self-made antibiotic coating retrograde hindfoot arthrodesis nail is used in order to achieve ankle fusion. We use a bone-substitute loaded with gentamicin (Cerament-G®) to fill the bone defects and to achieve high concentration of local gentamicin, to protect bone healing and to decrease the risk of relapse. We present four patients with ankle-osteomyelitis after open pilon fracture treated by such protocol. We receive all patients > 6 months after the initial fracture. In all cases type III-B open pilon fracture was the initial injury. All the patients presented psychological disturbances and the possibility of perform an external frame reconstruction was considered not indicated. At presentation, all patients have compromised skin around the distal tibia area. According to the Cierny/Mader osteomyelitis classification all patients were Type IV-Blocal. Compromises soft tissues were treated with an ALT free flap in two cases and with a Keystone flap in two cases. 10 mL paste of Cerament-G® was used in each case with a single case where a white-draining event was present without further complication. Tibiotalocalcaneal fusion was achieved after 4 months in all cases. At average of 7 months of follow-up, none of the four fused ankles has required further surgery and no infection relapse was observed. The use of this salvage treatment protocol has proven safe and useful for such difficult problem in these difficult patients, with a relatively low associated complication rate. Cerament-G® is a useful tool in order to fill all the bone voids, promote bone healing and simultaneously to protect the surgical area due to the high local concentration of gentamicin

Introduction

Hindfoot intramedullary nail fixation (HFN) or fibula pro-tibial screw fixation (PTS) are surgical options for ankle fractures in patients with multiple co-morbidities; we compared their outcomes.

We report the outcomes of 20 patients (12 men, 8 women, 21 feet) with Charcot neuro-arthropathy who underwent correction of deformities of the ankle and hindfoot using retrograde intramedullary nail arthrodesis. The mean age of the patients was 62.6 years (46 to 83); their mean BMI was 32.7 (15 to 47) and their median American Society of Anaesthetists score was 3 (2 to 4). All presented with severe deformities and 15 had chronic ulceration. All were treated with reconstructive surgery and seven underwent simultaneous midfoot fusion using a bolt, locking plate or a combination of both. At a mean follow-up of 26 months (8 to 54), limb salvage was achieved in all patients and 12 patients (80%) with ulceration achieved healing and all but one patient regained independent mobilisation. There was failure of fixation with a broken nail requiring revision surgery in one patient. Migration of distal locking screws occurred only when standard screws had been used but not with hydroxyapatite-coated screws. The mean American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS-FAO) score improved from 50.7 (17 to 88) to 65.2 (22 to 88), (p = 0.015). The mean Short Form (SF)-36 Health Survey Physical Component Score improved from 25.2 (16.4 to 42.8) to 29.8 (17.7 to 44.2), (p = 0.003) and the mean Euroqol EQ‑5D‑5L score improved from 0.63 (0.51 to 0.78) to 0.67 (0.57 to 0.84), (p = 0.012).

Single-stage correction of deformity using an intramedullary hindfoot arthrodesis nail is a good form of treatment for patients with severe Charcot hindfoot deformity, ulceration and instability provided a multidisciplinary care plan is delivered.

Conventional methods of treating ankle fractures in the elderly are associated with high rates of complication. We describe the results of treating these injuries in 48 frail elderly patients with a long calcaneotalotibial nail.

The mean age of the group was 82 years (61 to 96) and 41 (85%) were women. All were frail, with multiple medical comorbidities and their mean American Society of Anaesthesiologists score was 3 (3 to 4). None could walk independently before their operation. All the fractures were displaced and unstable; the majority (94%, 45 of 48) were low-energy injuries and 40% (19 of 48) were open.

The overall mortality at six months was 35%. Of the surviving patients, 90% returned to their pre-injury level of function. The mean pre- and post-operative Olerud and Molander questionnaire scores were 62 and 57 respectively. Complications included superficial infection (4%, two of 48); deep infection (2%, one of 48); a broken or loose distal locking screw (6%, three of 48); valgus malunion (4%, two of 48); and one below-knee amputation following an unsuccessful vascular operation. There were no cases of nonunion, nail breakage or peri-prosthetic fracture.

A calcaneotalotibial nail is an excellent device for treating an unstable fracture of the ankle in the frail elderly patient. It allows the patient to mobilise immediately and minimises the risk of bone or wound problems. A long nail which crosses the isthmus of the tibia avoids the risk of peri-prosthetic fracture associated with shorter devices.

Abstract. Background. Tibiotalocalcaneal (TTC) fusion is indicated for severe arthritis, failed ankle arthroplasty, avascular necrosis of talus and as a salvage after failed ankle fixation. Patients in our study had complex deformities with 25 ankles having valgus deformities (range 50–8 degrees mean 27 degrees). 12 had varus deformities (range 50–10 degrees mean 26 degrees) 5 ankles an accurate measurement was not possible on retrospective images. 10 out of 42 procedures were done after failed previous surgeries and 8 out of 42 had talus AVN. Methods. Retrospective case series of patients with hindfoot nails performed in our centre identified using NHS codes. Total of 41 patients with 42 nails identified with mean age of 64 years. Time to union noted from X-rays and any complications noted from the follow-up letters. Patients contacted via telephone to complete MOXFQ and VAS scores and asked if they would recommend the procedure to patients suffering similar conditions. 17 patients unable to fill scores (5 deceased, 4 nails removed, 2 cognitive impairment and 6 uncontactable). Results. In our cohort 33/38 of hindfoot nails achieved both subtalar and ankle fusion in a mean time of 7 months. 25 patients with 26 nails had mean follow up with post op scores of 4 years. Their Mean MOXFQ scores were (Pain: 12.8 Walking: 12 Social: 8) and visual analogue pain score was 3. 85% of patients wound recommend this surgery for a similar condition. 20 complications with 15 requiring surgery(5 screw removals, 1 percutaneous drilling, 1 fusion site injection, 8 nail revisions). Conclusion. In our experience hindfoot nail TTC fusion reliably improves the function of patients with severe symptoms in a variety of pathophysiological conditions and complex deformities. Most of our patients would recommend this procedure. There is a lack of studies with long-term follow-up

Introduction. The management of open or unstable ankle and distal tibial fractures pose many challenges. In certain situations, hindfoot nailing (HFN) is indicated, however this depends on surgeon preference and regional variations exist. This study sought to establish the current management and outcomes of complex ankle fractures in the UK. Methods. A National collaborative study in affiliation with BOTA was conducted and data retrospectively collected between January 1. st. – June 30. th. 2019. Adult patients with open and closed complex ankle fractures (AO43/44) were included. Complex fractures included the following patient characteristics: diabetes ± neuropathy, rheumatoid arthritis, alcoholism, polytrauma and cognitive impairment. We obtained data on fixation choice and patient outcomes. Institutional approval was obtained by all centres, and statistical analysis was performed including propensity matching. Results. Fifty-six centres provided data for 1360 patients. The average age of the cohort was 53.9 years ±19 (SD) with a male/female ratio of 1:1.3. 920 patients were ASA 1/2, 440 were ASA 3/4; 316 had diabetes, and 275 were open fractures. Most fractures were AO44 (71.2%) and more commonly associated with diabetes (P<0.001), alcoholism (P<0.007), open (P<0.013), and advanced age (55.7 vs. 46.3). 1227 patients underwent primary-fixation (111 HFN), with the remainder treated with external-fixation (84 definitive). Of the 111 HFN, 35% underwent primary fusion. Wound complication and thromboembolic rates were greater in the HFN group compared to ORIF groups (P<0.003), being more evident in the HFN group with primary fusion even after propensity matching. However, 1081 patients were non-weightbearing post-op contrary to the BOAST guidance. Conclusion. This is the first National collaborative audit of complex ankle fractures. Hindfoot nails were used in 9% of patients and we observed more complications in this group when compared to other cohorts. Despite BOAST guidance, only 21% of patients undergoing operative management were instructed to fully weightbear post-operatively

Aims. In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method. Methods. We conducted a retrospective analysis of prospectively collected data of all patients with infected Charcot foot deformity who underwent two-stage reconstruction with internal fixation between July 2011 and November 2019, with a minimum of 12 months’ follow-up. Results. We identified 23 feet in 22 patients with a mean age of 56.7 years (33 to 70). The mean postoperative follow-up period was 44.7 months (14 to 99). Limb salvage was achieved in all patients. At one-year follow-up, all ulcers have healed and independent full weightbearing mobilization was achieved in all but one patient. Seven patients developed new mechanical skin breakdown; all went on to heal following further interventions. Fusion of the hindfoot was achieved in 15 of 18 feet (83.3%). Midfoot fusion was achieved in nine of 15 patients (60%) and six had stable and painless fibrous nonunion. Hardware failure occurred in five feet, all with broken dorsomedial locking plate. Six patients required further surgery, two underwent revision surgery for infected nonunion, two for removal of metalwork and exostectomy, and two for dynamization of the hindfoot nail. Conclusion. Two-stage reconstruction of the infected and deformed Charcot foot using internal fixation and following the principle of ‘long-segment, rigid and durable internal fixation, with optimal bone opposition and local antibiotic elusion’ is a good form of treatment provided a multidisciplinary care plan is delivered.

Abstract. Objectives. Currently, the golden standard for the management of ankle fractures is open reduction and internal fixation (ORIF), a procedure which preserves joint anatomy and function. However, ORIF is associated with high risk of infection, especially in the elderly population, who tend to suffer from osteoporosis and vascular disease. Studies recommend hindfoot nailing (HFN) as a safe and efficient management alternative for this demographic. Unlike ORIF, HFN allows immediate weight-bearing, which has been linked to a lower rate of complications. This study aims to evaluate the outcomes of hindfoot nailing in ankle fractures using a case series of 43 patients. Methods. This is a retrospective study with a sample size of 43 patients, that have a mean age of 77.3 years and several medical conditions. These patients experienced ankle fractures that were treated with HFN. Data collected included injury patterns, operative complications, rate of radiological union, comorbidities and changes in mobility and housing before and after surgery. Results. Before their fracture, 62.8% of patients mobilised using a walking stick or a wheeled frame. Following surgery, 52.4% experienced decreased level of mobility. 50% of patients achieved radiological union at the time of data analysis, whereas 52.4% of patients reported a post-operative complication, most commonly soft tissue or bone infection. Conclusions. Our study has a large sample size compared to previous research. The follow-up period varies depending on patient attendance to follow-up clinical appointments. Our patient cohort exhibits significantly lower rates of radiological union, higher incidence of complications and poor post-operative functional outcomes associated with HFN. These data contradict previous studies suggesting HFN for the surgical management of ankle fractures in the elderly and frail population and demonstrate that a more thorough evaluation of HFN is needed

Tibiotalocalcaneal arthrodesis (TTCA) is a salvage procedure to functionally block the ankle and subtalar joints to treat severe ankle and hindfoot disease. Complication rates range between 20-40%, with below-knee amputation rate 1.5-19%. The heterogeneous patient cohort and indication(s) for surgery make post-operative outcomes difficult to predict. Consulting patients about potential pain and functional outcomes is difficult. When researching this area commonly, PROM data is used, less frequently functional objective measures like the 2-minute-walk-test (2MWT) are used. The aim was to compare the PROMs and objective outcomes between patients who underwent TTCA and BKA. Fifty-two patients underwent a TTCA using an intramedullary hindfoot nail. Indications for TTCA, post-traumatic OA, failed arthrodesis and malalignment. These patients were compared to 11 patients who underwent unilateral below knee amputation (BKA) due to trauma. Outcomes measures PROMs AOFAS ankle hindfoot scale and Shor-Form 36 (SF-36). Objective measures; 2MWT, Timed-up-and-go (TUG). Mean age TTCA 55.9, BKA 46.4. Average follow-up time 53 months. TTCA group had average 6.3 operations prior to arthrodesis (range 1-23). Of the TTCA group two ankles did not unite (7%), all complication rate 35%, 18% reported no pain. A significant negative correlation was demonstrated between the clinical outcome and the number of surgeries prior to the TTCA. TUG and 2MWT had significantly (p<0.05) better outcomes for the BKA group compared to TTCA. SF-36 BKA patients scored higher than the TTCA patients on physical functioning (p<0.01) and mental health (p<0.05) subscales as well as the mental component score (p<0.05). This study gives clinicians evidence about the natural history of hindfoot arthrodesis and functional outcomes from BKA. Hopefully this study will improve evidence to help patients and surgeons make decisions about expected surgical outcomes from TTCA and BKA procedures

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

Introduction. Ankle fractures represent approximately 10% of the fracture workload and are projected to increase due to ageing population. We present our 5 years outcome review post-surgical management of ankle fractures in a large UK Trauma unit. Methods. A total of 111 consecutive patients treated for an unstable ankle fracture were entered into a database and prospectively followed up. Baseline patient characteristics, complications, further intervention including additional surgery, functional status were recorded during five-year follow-up. Pre-injury and post-fixation functional outcome measures at 2-years were assessed using Olerud-Molander Ankle Scores (OMAS) and Lower Extremity Functional Scales (LEFS). A p value < 0.05 was considered significant. Results. The mean age was 46 with a male:female ratio of 1:1.1. The distribution of comorbidities was BMI >30 (25%), diabetes (5%), alcohol consumption >20U/week (15%) and smoking (26%). Higher BMI was predictive of worse post-op LEFS score (p = 0.02). Between pre-injury and post fixation functional scores at 2 years, there was a mean reduction of 26.8 (OMAS) and 20.5(LEFS). Using very strict radiological criteria, 31 (28%) had less than anatomical reduction of fracture fragments intra-operatively. This was, however, not predictive of patients' functional outcome in this cohort. Within 5-year period, 22 (20%) patients had removal of metalwork from their ankle, with majority 13 (59%) requiring syndesmotic screw removal. Further interventions included: joint injection (3), deltoid reconstruction (1), arthroscopic debridement (1), superficial sinus excision (2), and conversion to hindfoot nail due to failure of fixation (1). Reduction in OMAS was predictive of patients' ongoing symptoms (p=0.01). Conclusion. There is a significant reduction in functional outcome after ankle fracture fixation and patients should be counselled appropriately. Need for removal of metalwork is higher in patients who require syndesmosis stabilisation with screw(s)

Introduction. Ankle fractures in the elderly are an increasing problem with our aging population. Options for treatment include non-operative and operative with a range of techniques available. Failure of treatment can lead to significant complications, morbidity and poor function. We compared the outcomes of two operative techniques, intramedullary hindfoot nailing (IMN) and fibular-pro-tibia fixation (FPT). This is the largest analysis of these techniques and there are no comparative studies published. Method. We retrospectively reviewed patients over the age of 60 with ankle fractures who were treated operatively between 2012 and 2017. We identified 1417 cases, including 27 patients treated with IMN and 41 treated with FPT. Age, sex, co-morbidities and injury pattern were collected. Primary outcome was re-operation rate. Secondary outcomes included other complications, length of stay and functional status. Results. The IMN group had a higher average co-morbidity score compared with the FPT group (estimated 10-year survival, 21% vs 53%, p=0.03). Re-operation rate was higher in the IMN group compared with FPT (12 v 1, p< 0.0001). There were more complications in the IMN group compared with the FPT group (23 v 11, p< 0.0001). Length of stay was longer in the IMN group (17 v 29 days, p=0.02). Mobility tended to return to baseline in the FPT patients but decreased in the IMN patients. Conclusion. Outcomes were worse in the IMN group compared with the FPT group in terms of re-operation, complications and length of stay. However, the IMN group tended to have increased comorbidities and poorer soft tissues. We believe that both techniques have a role in the management of elderly ankle fractures, but patient selection is key. We suggest FPT should be the first-choice technique when soft tissues permit. We discuss the indications, risks and benefits of each method based on our experience and literature review

Fragility ankle fractures are traditionally managed conservatively or with open reduction internal fixation (ORIF). Tibiotalocalcaneal (TTC) fusion is an alternative option for the geriatric patient. This systematic review and meta-analysis provides a detailed analysis of the functional and clinical outcomes of hindfoot nailing for fragility ankle fractures presented so far in the literature. A systematic search was performed on MEDLINE, EMBASE, Cochrane Library, Scopus, Web of Science, identifying fourteen studies for inclusion. Studies including patients over 60 with a fragility ankle fracture, treated with TTC nail were included. Patients with a previous fracture of the ipsilateral limb, fibular nails, and pathological fractures were excluded. Subgroup analyses were performed according to (1) open vs closed fractures, (2) immediate post-operative FWB vs post-operative NWB, (3) majority of cohort are diabetics vs minority of cohort are diabetics. Meta-regression analyses were done to explore sources of heterogeneity, and publication bias was assessed using Egger's test. The pooled proportion of superficial infection, deep infection, implant failure, malunion, and all-cause mortality was 0.10 (95%CI:0.06-0.16; I2=44%), 0.08 (95%CI:0.06-0.11, I2=0%), 0.11 (95%CI:0.07-0.15, I2=0%), 0.11 (95%CI:0.06-0.18; I2=51%), and 0.27 (95%CI:0.20-0.34; I2=11%), respectively. The pooled mean post-operative OMAS score was 54.07 (95%CI:48.98-59.16; I2=85%). The best-fitting meta-regression model included age and percentage of male patients as covariates (p=0.0263), and were inversely correlated with higher OMAS scores. Subgroup analyses showed that studies with a majority of diabetics had a higher proportion of implant failure (p=0.0340) and surgical infection (p=0.0096), and a lower chance of returning to pre-injury mobility than studies with a minority of diabetics (p=0.0385). Egger's test (p=0.56) showed no significant publication bias. TTC nailing is an adequate alternative option for fragility ankle fractures. However, current evidence includes mainly case series with inconsistent outcome measures reported and post-operative rehabilitation protocols. Prospective RCTs with long follow-up times and large cohort sizes are needed to clearly guide the use of TTC nailing for ankle fractures

Introduction. Primary ankle arthroplasty (TAR) is increasingly used to treat end-stage ankle arthritis. Reported revision rates of TAR vary from 8.5% to 11.1% at 9 years. Revision surgery remains technically challenging with options ranging from simple joint debridement to tibio-talar-calcaneal fusion. The efficacy of these procedures remains unclear and there is no consensus on optimal revision options. Methods. A retrospective cohort study was performed of all patients undergoing surgery for a failed primary TAR at the Nuffield Orthopaedic Centre (2004–2021). TAR failure was determined by clinical assessment, serial radiographs and CT scans. Primary outcome measures included type and time of index surgery post TAR. Secondary outcomes included frequency of re-operations, post-operative complications, patient reported outcomes and union rate (for revision arthrodesis procedures). Results. 70 failed TARs in 69 patients (35M:34F, mean 65.7 years, s.d.=11.6) underwent re-operation a mean of 6.24 years (range 1–30) post primary. In total, 107 operations were performed including revision fusion (n=50), revision arthroplasty (n=14), bearing exchange (n=9) and joint clearance (n=9). The overall revision fusion union rate was 73.5% over a mean of 12.5 months (s.d.=7.6). 16/23 (69.6%) Tibio-Talo-Calcaneal and 9/12 (75%) ankle fusions (previous subtalar/triple fusion) using a hindfoot nail united over a mean 11.4 months (s.d.=6.0) and 15 months (s.d.=9.48) respectively. Only 64% of ankle fusions using screws alone united (mean=10.6 months, s.d.=8.14). The average post-operative MOXFQ score was 28.3 (s.d.=19.3). 73% said the operation improved their function and would recommend it to a friend/family member. Conclusion. Despite low post-operative MOXFQ scores, over 70% of patients were satisfied with re-operation for a failed TAR. Over 26% of all TAR revision fusions fail to unite with the highest non-union rates observed post ankle arthrodesis with screws alone (36.4%)

The August 2013 Foot & Ankle Roundup. 360 . looks at: mobility, ankles and fractures; hindfoot nailing: not such a bad option after all?; little treatment benefit for blood injection in tendonitis; fixed bearing ankles successful in the short term; hindfoot motion following STAR ankle replacement; minimally invasive calcaneal fracture fixation?; pes planus in adolescents; and subluxing peroneals and groove deepening

Introduction. Open fractures are fortunately rare but pose an even greater challenge due to poor soft tissues, in addition to poor bone quality. Co-morbidities and pre-existing medical conditions, in particular, peripheral vascular diseases make them often unsuitable for free flaps. We present our experience in treating severe open fractures of tibia with Acute Intentional Deformation (AID) to close the soft tissues followed by gradual correction of deformity to achieve anatomical alignment of the tibia and fracture healing with Taylor Spatial Frame. Materials and Methods. We treated 4 geriatric (3 female and 1 male) patients with Gustillo-Anderson III B fractures of the tibia between 2017–18. All were unfit to undergo orthoplastic procedures (free flap or local flaps). The age range is 69 yrs to 92 years. Co-morbidities included severe rheumatoid arthritis, multiple sclerosis and heart failure. The procedure involved wound debridement, application of two ring Taylor Spatial Frame, acute deformation of the limb on the table to achieve soft-tissue closure/approximation. Regular neurovascular assessments were performed in the immediate post-operative period to monitor for compartment syndrome and nerve compression symptoms. After 7–10 days of latent period, the frame was gradually manipulated, according to a method we had previously published, to achieve anatomical alignment. The frame was removed in clinic after fracture healing. Results. Time in frame ranged from 1.5 months to 7 months. In one patient (92 yr old with an open fracture of the ankle) hindfoot nail was inserted after soft-tissue closure was achieved at 1.5 months, and frame removed. We achieved complete healing of soft tissue wounds without any input from plastic surgeons in all patients. All fractures healed in anatomical alignment. 3 patients had one episode of superficial pin infection each requiring 5 days of oral antibiotics. None of the patients developed a deep infection. Conclusions. Acute intentional deformation (AID) with Taylor Spatial Frame achieves good closure of soft tissues in physiologically compromised geriatric patients who were deemed unfit for plastic surgery. We also achieved fracture healing in all four cases without any major complications
