Lisfranc injuries were previously described as fracture-dislocations of the tarsometatarsal joints. With advancements in modern imaging, subtle Lisfranc injuries are now more frequently recognized, revealing that their true incidence is much higher than previously thought. Injury patterns can vary widely in severity and anatomy. Early diagnosis and treatment are essential to achieve good outcomes. The original classification systems were anatomy-based, and limited as tools for guiding treatment. The current review, using the best available evidence, instead introduces a stability-based classification system, with weightbearing radiographs and CT serving as key diagnostic tools. Stable injuries generally have good outcomes with nonoperative management, most reliably treated with immobilization and non-weightbearing for six weeks. Displaced or comminuted injuries require surgical intervention, with open reduction and internal fixation (ORIF) being the most common approach, with a consensus towards bridge plating. While ORIF generally achieves satisfactory results, its effectiveness can vary, particularly in high-energy injuries. Primary arthrodesis remains niche for the treatment of acute injuries, but may offer benefits such as lower rates of post-traumatic arthritis and hardware removal. Novel fixation techniques, including suture button fixation, aim to provide flexible stabilization, which theoretically could improve midfoot biomechanics and reduce complications. Early findings suggest promising functional outcomes, but further studies are required to validate this method compared with established techniques. Future research should focus on refining stability-based classification systems, validation of weightbearing CT, improving rehabilitation protocols, and optimizing surgical techniques for various injury patterns to ultimately enhance patient outcomes.

Introduction. Charcot neuroarthropathy (CN) of foot and ankle presents significant challenges to the orthopaedic foot and ankle surgeon. Current treatment focuses on conservative management during the acute CN phase with offloading followed by deformity correction during the chronic phase. However, the deformity can progress in some feet despite optimal offloading resulting ulceration, infection, and limb loss. Our aim was to assess outcomes of primary surgical management with early reconstruction. Methods. Between December 2011 and December 2019, 25 patients underwent operative intervention at our specialist diabetic foot unit for CN with progressive deformity and or instability despite advanced offloading. All had peripheral neuropathy, and the majority due to diabetes. Twenty-six feet were operated on in total - 14 during Eichenholtz stage 1 and 12 during stage 2. Fourteen of these were performed as single stage procedures, whereas 12 as two-stage reconstructions. These included isolated hindfoot reconstructions in seven, midfoot in four and combined in 14 feet. Mean age at the time of operation was 54. Preoperative ulceration was evident in 14 patients. Results. Mean follow up was 45 months (Range 12–98). There was 100% limb salvage. One-year ambulation outcomes demonstrate FWB in bespoke footwear for 17 patients and in an ankle foot orthosis (AFO), Charcot restraint orthopaedic walker (CROW) or bivalve cast for seven. All preoperative ulceration had healed. Union was achieved in 18/21 hindfoot reconstructions and 7/18 midfoot reconstructions. There were nine episodes of return to theatre, of which five were within the first 12 months. There was one episode of new ulceration. Conclusion. Surgical management of acute CN (Eichenholtz one and two) of the foot provides functional limb salvage. In particular, hindfoot reconstruction shows good rates of bony union. It should be considered in ‘foot at risk’ presentations of acute CN foot

Background. Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children, or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severe neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has excellent functional outcome. Objective. To assess the functional outcome of acute correction of neglected Talipes-quino-varus deformity in adults. Methods. This is cross sectional, hospital–based study that took place in Khartoum, Sudan. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed to all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopaedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one years after surgery. Results. The mean age was 19.9±4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7±7.1 (poor). This score improved to 80.7±13.7 (good to excellent), two years after surgery. However, this indicates significant change in the functional outcome after the operation (P value < 0.05). Excellent post-operative functional outcome was found among patients aged 18 – 23 years 18 (50%) P. value: 0.021. The majority of patients 36(90%) were fully satisfied with the operation, 2(5%) partially satisfied and 2(5%) were unsatisfied. Conclusion. Acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure

Introduction. Tibial Pilon fractures are potentially limb threatening, yet standards of care are lacking from BOFAS and the BOA. The mantra of “span, scan, plan” describes staged management with external fixation to allow soft tissue resuscitation, followed by a planning CT-scan. Our aim was to evaluate how Tibial Pilon fractures are acutely managed. Methods. ENFORCE was a multi-centre retrospective observational study of the acute management of partial and complete articular Tibial Pilon fractures over a three-year period. Mechanism, imaging, fracture classification, time to fracture reduction and cast, and soft tissue damage control details were determined. Results. 656 patients (670 fractures) across 27 centres were reported. AO fracture classifications were: partial articular (n=294) and complete articular (n=376). Initial diagnostic imaging mobilities were: plain radiographs (n=602) and CT-scan (n=54), with all but 38 cases having a planning CT-scan. 526 fractures had a cast applied in the Emergency Department (91 before radiological diagnosis), with the times taken to obtain post cast imaging being: mean 2.7 hours, median 2.3 hours, range 28 mins – 14 hours). 35% (102/294) of partial articular and 57% (216/376) of complete articular (length unstable) fractures had an external fixator applied, all of which underwent a planning CT-scan. Definitive management consisted of: open reduction internal fixation (n=495), fine wire frame (n=86), spanning external fixator (n=25), intramedullary nail (n=25), other (n=18). Conclusion. The management of Tibial Pilon fractures is variable, with prolonged delays in obtaining post cast reduction radiographs, and just over half of length unstable complete articular fractures being managed with the gold standard “span, scan, plan” staged soft tissue resuscitation. A BOFAS endorsed BOAST (British Orthopaedic Association Standard for Trauma) for Tibial Pilon fractures is suggested for standardisation of the acute management of these potentially limb threatening injuries, together with setting them apart from more straightforward ankle fractures

Aims. This prospective cohort study aimed to determine if the size of the tendon gap following acute tendo Achillis rupture influences the functional outcome following non-operative treatment. Patients and methods. All patients presenting with acute unilateral tendo Achillis rupture were considered for the study. Dynamic ultrasound examination was performed to confirm the diagnosis and measure the gap between ruptured tendon ends. Outcome was assessed using dynamometric testing of plantarflexion and the Achilles tendon rupture score (ATRS) six months after the completion of a rehabilitation programme. Results. 38 patients (mean age 52 years, range 29–78 years) completed the study. Patients with a gap ≥10mm with the ankle in the neutral position had significantly greater peak torque deficit than those with gaps < 10mm (mean 23.3% vs 14.3%, P=0.023). However, there was no overall correlation between gap size and torque deficit (τ=0.103), suggesting a non-linear relationship. There was also weak correlation between ATRS and peak torque deficit (τ=−0.305), with no difference in ATRS between the two groups (mean score 87.2 vs 87.4, P=0.467). Conclusion. This is the first study to identify tendon gap size as a predictor of functional outcome in acute tendo Achillis rupture, although the precise relationship between gap size and plantarflexion strength remains unclear. Large, multi-centre studies will be needed to clarify this relationship and identify population subgroups in whom deficits in peak torque are reflected in patient-reported outcome measures

Introduction:. Charcot arthropathy is a complex condition affecting diabetic patients with neuropathy. Diagnosis of acute Charcot arthropathy particularly in absence of any perceptible trauma is very challenging as clinically it can mimic osteomyelitis and cellulitis. Delay in recognition of Charcot arthropathy can result in gross instability of foot and ankle. Early diagnosis can provide an opportunity to halt the progression of disease. We report the role of SPECT /CT in the early diagnosis and elucidation of the natural progression of the disease. Methods:. Our multidisciplinary team analysed the scans of neuropathic patients presented with acute red, hot, swollen foot with normal radiological findings (Eichenholtz stage 0), attending the diabetic foot clinic from 2009–2013. The patients were selected from our database, clinic and nuclear medicine records. Initial workup included the assessment of peripheral neuropathy, temperature difference, between the feet, serum inflammatory markers and weight bearing dorsoplantar, lateral and oblique x-rays. All patients had three dimensional triple Phase Bone Scan using 800Mbq . 99m. Tc HDP followed by CT scan. Those patients with obvious radiological findings and signs of infection were excluded. Results:. We evaluated 193 scans in 189 patients. One hundred and forty nine patients showed increase in focal radionuclide uptake at ligament insertion or subchondral bone with a positive predictive value of 77 percent. Forty four out of 193 were negative for Charcot changes and they were not treated as Charcot. These patients did not develop any Charcot changes in the mean follow up of 8 months, indicating a clinically false positive rate of 23%. Conclusion:. SPECT/CT scan is a highly sensitive and specific tool for early diagnosis and accurate localisation of Charcot neuroarthropathy as clinical examination results in high false positive rate. SPECT/CT also helps to understand the natural progression of this disease

The aim of this project was to look at time taken to achieve clinical resolution of diabetic charcot neuroarthropathy (CN) and to see if there was a correlation with location within the foot and overall outcomes. A retrospective analysis of newly presenting acute CN patients between 2007 & 2012 was performed. Clinic records were examined to determine the site of the CN; total time treated in a TCC or other removable offloading devices; the presence of co-morbidities. Fifty CN cases presented during this time. The mean age was 62.5±11.7 (SD) years. Eleven patients had type 1 diabetes mellitus (T1DM). The mean duration of diabetes was 29.7±12.9 years for T1DM, and 14.4±10.7 years for type 2 diabetics. All had palpable foot pulses & peripheral neuropathy at diagnosis. 82% had retinopathy; 34% had CKD stage 3–4. For the 42 patients who completed treatment, the mean duration was 53.9±28.0 weeks, of which a mean of 30.2±25.0 weeks was spent in a TCC. 23.7±16.2 weeks were spent in other offloading devices. Mean duration of treatment for forefoot, mid-foot & hind-foot was 47.2±22.6, 55.9±30.6 & 51.8±23.1 weeks respectively. Thirty-six patients were treated with TCC & other removable offloading devices, 6 were treated with one modality. Fourteen of the 36 (38.9%) required re-casting. Eight patients did not complete treatment: 4 underwent below knee amputation, 2 died, 2 were still undergoing treatment. In our cohort the mean length of treatment is dependent on the position of the CN. The mean time to resolution is just over 1 year. However, a high percentage (38.9%) deteriorated after coming out of a TCC. This study highlights the need to develop more precise measures to help manage acute CN

Injury to the syndesmosis occurs in approximately 10% of all patients with ankle fractures. Anatomic restoration of the syndesmosis is the only significant predictor of functional outcome. Several techniques of syndesmosis fixation are currently used such as cortical screws, bioabsorbable screws and more recently introduced suture-button fixation. No single technique has been shown to be superior to the others. The objective of this research project is to investigate whether treatment with a tightrope (suture-button fixation) gives superior results than the use of a cortical screw in the treatment of acute syndesmotic ankle injuries with regards to function, pain, satisfaction and return to normal activities. Research Ethics Committee approval was obtained. 40 patients with syndesmotic ankle injuries associated with diastasis were prospectively recruited, 20 in each group. Patients were randomized to one of the 2 groups. At 12 weeks, American Orthopaedic Foot and Ankle Society (AOFAS) scores and a computerized tomography (CT) scan of both the ankles was obtained. At 1 year, AOFAS scores and satisfaction was assessed. 32 patients have been recruited so far, 20 in the tightrope group and 12 in the cortical screw group. Mean AOFAS scores at 3 months post-op were 90.67 in the Tightrope group and 84 in the screw group. The difference was not significant (p= 0.096). CT scans revealed that the quality of syndesmosis reduction was equally good with both the techniques. Metalwork prominence was common with both the devices. Discussion and Conclusion. Both the devices achieved good reduction of the syndesmosis. Our CT scan protocol has insignificant radiation risk and allows more accurate assessment of the syndesmosis. Early clinical results do not show a significant difference in the functional outcome with the use of either device. Long-term (1 year) follow-up has been planned

Introduction

Active patients may benefit from surgical repair of the achilles tendon with the aim of preserving functional length and optimising push-off power. A mini-open device assisted technique has the potential to reduce wound complications, but risks nerve injury. We present the largest published series of midsubstance achilles tendon repairs using the Achillon® device.

The best method of stabilisation of the ankle syndesmosis remains a topic of debate; a relatively recent development is the ankle tightrope – a tensionable fibrewire suture device. Despite over 30,000 successful surgeries reported, evidence supporting its use when compared with screw fixation remains extremely limited. We retrospectively compared two consecutive groups of patients whose syndesmotic injuries were stabilised either with a tightrope or screws. The aim of our study was to compare complications arising after insertion of these devices.

All patients undergoing tightrope stabilisation of the syndesmosis between January 2006 and February 2009 were included as the treatment group. The control group was made up of a similar number of consecutive patients who underwent screw stabilisation between November 2010 and January 2011. Data was obtained through theatre records, case notes and from the local PACS X-ray system. Eighteen eligible cases were identified in the tightrope group compared with sixteen eligible cases treated with screws. Both groups had similar baseline demographics with respect to distribution of age and gender.

Twenty two percent (n = 4) of tightropes were removed secondary to wound breakdown or knot prominence. Other complications included persistent syndesmotic widening (n = 2, 11%), knot prominence without removal (n = 1, 5.5%) and synostosis (n = 1, 5.5%). In comparison, only 1 patient (6.3%) experienced a complication (pain and decreased RoM) in the control group. A total of 14 screws were removed. Thirteen screws were removed uneventfully. One patient was discharged to another hospital for a planned removal of screw, but was lost to follow-up. The remaining two patients elected not to have their screws removed.

Introduction

Lisfranc joint injuries are increasingly recognised in elite soccer and rugby players. Currently no evidence-based guidelines exist on timeframes for return to training and competition following surgical treatment. This study aimed to see whether return to full competition following surgery for Lisfranc injuries was possible in these groups and to assess times to training, playing and possible related factors.

Aim. Our collaborative study aims to demonstrate that acute partial Achilles Tendon Tears (ATTs) are not separate diagnostic entities from full ATTs. and should be thought of as a continuum rather than binary partial or full. Methods. We pooled anonymised data from four hospitals, identifying patients with acute partial ATTs on USS reports from 2019–2021. Patients were only included if they had an acute injury and no previous background Achilles tendinopathy. Results. 91 patients had acute partial ATTs reported on USS. 74/91 (81%) of patients had clinical findings in keeping with a full ATT (positive Simmonds test, palpable gap). 88/91 (97%) of patients were managed according to local full ATT protocols. 2 patients had MRIs – one showed no tear, the other showed a full rupture. 2 patients underwent surgical repair and both intra-operatively were found to have full ATTs. Conclusion. Our regional data suggests that a significant proportion (81%) of USS diagnosed partial ATTs may in fact be misdiagnosed full ATTs. All injuries clinically suspicious for an ATT should be managed according to local Achilles Protocol. USS is useful to diagnose the presence or absence of a tear but is not good at differentiating partial vs full tear. There is significant tendon end fibrillation and overlap on USS of an acute full ATT, which can give the impression of a partial ATT. More research is needed into whether any threshold exists to support the current distinction of “partial” and “full” as relates to management and outcomes

Aims. Although absorbable sutures for the repair of acute Achilles tendon rupture (ATR) have been attracting attention, the rationale for their use remains insufficient. This study prospectively compared the outcomes of absorbable and nonabsorbable sutures for the repair of acute ATR. Methods. A total of 40 patients were randomly assigned to either braided absorbable polyglactin suture or braided nonabsorbable polyethylene terephthalate suture groups. ATR was then repaired using the Krackow suture method. At three and six months after surgery, the isokinetic muscle strength of ankle plantar flexion was measured using a computer-based Cybex dynamometer. At six and 12 months after surgery, patient-reported outcomes were measured using the Achilles tendon Total Rupture Score (ATRS), visual analogue scale for pain (VAS pain), and EuroQoL five-dimension health questionnaire (EQ-5D). Results. Overall, 37 patients completed 12 months of follow-up. No difference was observed between the two groups in terms of isokinetic plantar flexion strength, ATRS, VAS pain, or EQ-5D. No re-rupture was observed in either group. Conclusion. The use of absorbable sutures for the repair of acute ATR was not inferior to that of nonabsorbable sutures. This finding suggests that absorbable sutures can be considered for the repair of acute ATRs. Cite this article: Bone Joint J 2022;104-B(8):938–945

Aims. The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture. Methods. This is a secondary analysis of a multicentre randomized controlled trial comparing adults with an acute ankle fracture, initially managed either by operative or nonoperative care. Patients were randomly allocated to receive either a cast immobilization or a fixed-angle removable orthosis (removable brace). Data were collected on baseline characteristics, ankle function, quality of life, and complications. The Olerud-Molander Ankle Score (OMAS) was the primary outcome which was used to measure the participant’s ankle function. The primary endpoint was at 16 weeks, with longer-term follow-up at 24 weeks and two years. Results. Overall, 436 patients (65%) completed the final two-year follow-up. The mean difference in OMAS at two years was -0.3 points favouring the plaster cast (95% confidence interval -3.9 to 3.4), indicating no statistically significant difference between the interventions. There was no evidence of differences in patient quality of life (measured using the EuroQol five-dimension five-level questionnaire) or Disability Rating Index. Conclusion. This study demonstrated that patients treated with a removable brace had similar outcomes to those treated with a plaster cast in the first two years after injury. A removable brace is an effective alternative to traditional immobilization in a plaster cast for patients with an ankle fracture. Cite this article: Bone Joint J 2023;105-B(4):382–388

Introduction. Early clinical examination combined with MRI following a high ankle sprain allows accurate diagnosis of syndesmosis instability. However, patients often present late, and for chronic injuries clinical assessment is less reliable. Furthermore, in many centres MRI may be not be readily available. The aims of the current study were to define MRI characteristics associated with syndesmosis instability, and to determine whether MRI patterns differed according to time from injury. Methods. Retrospectively, patients with an unstable ligamentous syndesmosis injury requiring fixation were identified from the logbooks of two fellowship trained foot and ankle surgeons over a five-year period. After exclusion criteria (fibula fracture or absence of an MRI report by a consultant radiologist), 164 patients (mean age 30.7) were available. Associations between MRI characteristics and time to MRI were examined using Pearson's chi-square tests or Fisher's exact tests (significance set at p< 0.05). Results. Overall, 100% of scans detected a syndesmosis injury if performed acutely (within 6 weeks of injury), falling to 83% if performed after 12 weeks (p=0.001). In the acute group, 93.5% of patients had evidence of at least one of either PITFL injury (78.7%), posterior malleolus bone oedema (60.2%), or a posterior malleolus fracture (15.7%). In 20% of patients with a posterior malleolus bone bruise or fracture, the PITFL was reported as normal. The incidence of posterior malleolus bone bruising and fracture did not significantly differ according to time. Conclusion. For unstable ligamentous syndesmosis injuries, MRI becomes less sensitive over time. Importantly, posterior malleolus bone oedema or fracture may be the only evidence of a posterior injury. Failure to recognise instability may lead to inappropriate management of the patient, long term pain and arthritis. We therefore advocate early MRI as it becomes more difficult to ‘grade’ the injury if delayed

Aims. This study evaluated the effect of treating clinician speciality on management of zone 2 fifth metatarsal fractures. Methods. This was a retrospective cohort study of patients with acute zone 2 fifth metatarsal fractures who presented to a single large, urban, academic medical centre between December 2012 and April 2022. Zone 2 was the region of the fifth metatarsal base bordered by the fourth and fifth metatarsal articulation on the oblique radiograph. The proportion of patients allowed to bear weight as tolerated immediately after injury was compared between patients treated by orthopaedic surgeons and podiatrists. The effects of unrestricted weightbearing and foot and/or ankle immobilization on clinical healing were assessed. A total of 487 patients with zone 2 fractures were included (mean age 53.5 years (SD 16.9), mean BMI 27.2 kg/m. 2. (SD 6.0)) with a mean follow-up duration of 2.57 years (SD 2.64). Results. Overall, 281 patients (57.7%) were treated by orthopaedic surgeons, and 206 patients (42.3%) by podiatrists. When controlling for age, sex, and time between symptom onset and presentation, the likelihood of undergoing operative treatment was significantly greater when treated by a podiatrist (odds ratio (OR) 2.9 (95% CI 1.2 to 8.2); p = 0.029). A greater proportion of patients treated by orthopaedic surgeons were allowed to immediately bear weight on the injured foot (70.9% (178/251) vs 47.3% (71/150); p < 0.001). Patients treated by podiatrists were immobilized for significantly longer (mean 8.4 weeks (SD 5.7) vs 6.8 weeks (SD 4.3); p = 0.002) and experienced a significantly longer mean time to clinical healing (12.1 (SD 10.6) vs 9.0 weeks (SD 7.3), p = 0.003). Conclusion. Although there was considerable heterogeneity among zone 2 fracture management, orthopaedic surgeons were less likely to treat patients operatively and more likely to allow early full weightbearing compared to podiatrists.

Aims. Venous thromboembolism (VTE) is a potential complication of foot and ankle surgery. There is a lack of agreement on contributing risk factors and chemical prophylaxis requirements. The primary outcome of this study was to analyze the 90-day incidence of symptomatic VTE and VTE-related mortality in patients undergoing foot and ankle surgery and Achilles tendon (TA) rupture. Secondary aims were to assess the variation in the provision of chemical prophylaxis and risk factors for VTE. Methods. This was a multicentre, prospective national collaborative audit with data collection over nine months for all patients undergoing foot and ankle surgery in an operating theatre or TA rupture treatment, within participating UK hospitals. The association between VTE and thromboprophylaxis was assessed with a univariable logistic regression model. A multivariable logistic regression model was used to identify key predictors for the risk of VTE. Results. A total of 13,569 patients were included from 68 sites. Overall, 11,363 patients were available for analysis: 44.79% were elective (n = 5,090), 42.16% were trauma excluding TA ruptures (n = 4,791), 3.50% were acute diabetic procedures (n = 398), 2.44% were TA ruptures undergoing surgery (n = 277), and 7.10% were TA ruptures treated nonoperatively (n = 807). In total, 11 chemical anticoagulants were recorded, with the most common agent being low-molecular-weight heparin (n = 6,303; 56.79%). A total of 32.71% received no chemical prophylaxis. There were 99 cases of VTE (incidence 0.87% (95% CI 0.71 to 1.06)). VTE-related mortality was 0.03% (95% CI 0.005 to 0.080). Univariable analysis showed that increased age and American Society of Anesthesiologists (ASA) grade had higher odds of VTE, as did having previous cancer, stroke, or history of VTE. On multivariable analysis, the strongest predictors for VTE were the type of foot and ankle procedure and ASA grade. Conclusion. The 90-day incidence of symptomatic VTE and mortality related to VTE is low in foot and ankle surgery and TA management. There was notable variability in the chemical prophylaxis used. The significant risk factors associated with 90-day symptomatic VTE were TA rupture and high ASA grade. Cite this article: Bone Joint J 2024;106-B(11):1249–1256

Aims. Diabetic foot care is a significant burden on the NHS in England. We have conducted a nationwide survey to determine the current participation of orthopaedic surgeons in diabetic foot care in England. Methods. A questionnaire was sent to all 136 NHS trusts audited in the 2018 National Diabetic Foot Audit (NDFA). The questionnaire asked about the structure of diabetic foot care services. Results. Overall, 123 trusts responded, of which 117 admitted patients with diabetic foot disease and 113 had an orthopaedic foot and ankle surgeon. A total of 90 trusts (77%) stated that the admission involved medicine, with 53 (45%) of these admissions being exclusively under medicine, and 37 (32%) as joint admissions. Of the joint admissions, 16 (14%) were combined with vascular and 12(10%) with orthopaedic surgery. Admission is solely under vascular surgery in 12 trusts (10%) and orthopaedic surgery in 7 (6%). Diabetic foot abscesses were drained by orthopaedic surgeons in 61 trusts (52%) and vascular surgeons in 47 (40%). Conclusion. Orthopaedic surgeons make a significant contribution to both acute and elective diabetic foot care currently in the UK. This contribution is likely to increase with the movement of vascular surgery to a hub and spoke model, and measures should be put in place to increase the team based approach to the diabetic foot, for example with the introduction of a best practice tariff.

Introduction. Acute ankle injuries are commonly seen in musculoskeletal practice. Surgical management is the gold standard for lateral ligament injury in those with failed conservative treatment for a minimum of six months. Several studies have shown good functional outcome and early rehabilitation after MBG repair with an internal brace augmentation which is a braided ultrahigh molecular weight polyethylene ligament used to enhance the repair that acts as a secondary stabiliser. Hence the aim of the study was to compare the results with and without augmentation. Methods. A single centre retrospective review conducted between November 2017 and October 2019 and this included 172 patients with symptomatic chronic lateral ligament instability with failed conservative management. The diagnosis was confirmed by MRI. All patients had an ankle arthroscopy followed by open ligament repair. Patients were grouped into isolated MBG and internal brace groups for analyses and all had dedicated rehabilitation. Results. A total of 148 patients were available for final follow up with 87 patients in the MBG group and 61 patients in the IBA group. Mean Age was 38 years and mean follow up was 22 months. The internal brace group showed better Manchester Oxford foot and ankle score (19.7 vs 18.2) and more patients returning to preinjury activity levels (73 vs 55) as compared to isolated repair. Conclusion. Internal brace augmentation with MBG repair facilitated early rehabilitation and return to pre injury activity level in majority of patients compared to isolated MBG repair

Background. Venous Thrombo-Embolism is a recognized complication of lower limb immobilization. In the neuropathic patient total contact casting (TCC) is used in the management of acute charcot neuroathropathy and/or to off-load neuropathic ulcers, frequently for long time periods. To our knowledge there is no literature stating the prevalence of VTE in patients undergoing TCC. We perceive that neuropathic patients with active charcot have other risk factors for VTE which would predispose them to this condition and would mandate the use of prophylaxis. We report a retrospective case series assessing the prevalence of VTE in the patients being treated with TCCs. Methods. Patients undergoing TCC between 2006 and 2018 were identified using plaster room records. These patients subsequently had clinical letters and radiological reports assessed for details around the TCC episode, past medical history and any VTE events. Results. There were 143 TCC episodes in 104 patients. Average age at cast application was 55 years. Time in cast averaged 45 days (range 5 days – 8 months, median 35 days). 3 out of 4 patients had neuropathy as a consequence of diabetes. One TCC related VTE (0.7% of casting episodes) was documented. This was a proximal DVT confirmed on USS 9 days following cast removal. No patient received VTE prophylaxis while in TCC. Conclusion. Despite these complex patients having a multitude of co-morbidities the prevalence of VTE in the TCC setting remains similar to that of the general population. This may be due to the fact that TCCs permit weight bearing. This case series suggests that, while all patients should be individually VTE risk assessed as for any lower limb immobilization, chemical thromboprophylaxis is not routinely indicated in the context of TCCs
