Introduction. Venous thromboembolism (VTE) represents a major cause of morbidity, mortality and financial burden to the NHS. Acquired risk factors are well documented, including immobilisation, lower limb plaster cast and surgery. NICE guidance on VTE prophylaxis within orthopaedics currently excludes operative ankle fracture fixation (ankle ORIF). Aims. Ascertain the local incidence of VTE; compare our local VTE rates with published data from other institutions; review guidelines, scientific literature and other hospitals policies; formulate a local policy for VTE prophylaxis. Method. Retrospective analysis of records of all patients undergoing ankle ORIF in our hospital over a continuous 5 year period, identifying cases of VTE, individual risk factors and surgical duration. Results. 380 patients underwent ankle ORIF; 3 developed VTE; no mortality. VTE incidence 0.79% (0.26%DVT; 0.53%PE). Operative duration 88 +/− 34mins (mean +/− 1S.D); in those with VTE, duration was 35, 90&85min. There is no statistically significant difference (p=0.18) observed between our local and national VTE incidence rates. Operative duration was not a significant factor in those developing VTE. Additional risk factors were identified in one patient with VTE. Discussion. The incidence of heparin induced thrombocytopenia is 0.5%, its associated mortality 10% (i.e. 1:2000). To prevent one fatal PE in foot & ankle surgery, 10,000 must receive VTE prophylaxis. Therefore, heparin associated mortality exceeds VTE associated mortality in foot & ankle surgery. Conclusion. Our local VTE rates are comparable to national rates. Risk of pharmacological prophylaxis exceeds benefit; therefore routine use not justified. Individual risk should be assessed; higher risk patients may benefit

This is a case series report on the outcomes of patients that have received ORIF of their calcaneal fractures at Craigavon Hospital, Northern Ireland, for the first 2 years since it opened. It is a one surgeon series. Methods. Patients were identified from the theatre logbook. The patient recalled to clinic for interview and examination. Outcome was assessed using The Ankle-Hindfoot Scale devised by the American Orthopaedic Foot and Ankle Society. This was recorded with data for the patient's notes and CT scans. These data included age, date of surgery, mechanism of injury, associated injuries and previous function. The calcaneal fractures were classified according to the Sanders Classification. Results. Sixteen patients identified from the theatre register. Of these patients, 10 patients were contactable and attended for evaluation. The data from these 10 patients was then analysed. There 9 male patients and one female. Time from operation from 9.5 months to 33 months. All patients had fractures classified as Sanders Type IV. All implants were Variax calcaneal plates. One patient had metalwork removed at 15 months. All patients had commenced weightbearing at 3 months. Outcome scores ranged from 52–97 (mean 78.3, median 79). Six of the ten had returned to work at this review. Subtalar motion was universally affected. Discussion. This one surgeon case series reflects the current literature on calcaneal fractures, in that there is a variation in outcome which is multifactorial. There is also a difficulty in defining a classification system which can reflect outcome. The results of this series suggest that there is a trend of improving outcome scores as time from injury progresses, and that outcome score tends to decrease as age at injury increases

Objectives. The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Methods. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared. Results. The relative displacement of the EFLIF was less than that of the plate (0.1363 mm to 0.1808 mm). The highest von Mises stress value on the plate was 33% higher than that on the EFLIF. A normal restoration of the Böhler angle was achieved in both groups. No significant difference was found in the clinical outcome on the American Orthopedic Foot and Ankle Society Ankle Hindfoot Scale, or on the Visual Analogue Scale between the two groups (p > 0.05). Wound complications were more common in those who were treated with ORIF (p = 0.028). Conclusions. Both EFLIF and ORIF systems were tested to 160 N without failure, showing the new construct to be mechanically safe to use. Both EFLIF and ORIF could be effective in treating Sanders type 2 calcaneal fractures. The EFLIF may be superior to ORIF in achieving biomechanical stability and less blood loss, shorter surgical time and hospital stay, and fewer wound complications. Cite this article: M. Pan, L.

Background. Studies have compared open reduction internal fixation (ORIF) with fibular nail fixation (FNF) and shown reduced wound complications with minimal difference to PROMS in the short term. Our aim is to compare long-term outcomes for unstable ankle fractures at 10 year follow up. Methods. Patients from a previously conducted RCT were contacted at a minimum of 10 years post intervention at a single study centre. Case notes were reviewed, and patient reported outcome measures acquired at 10 years. Results. Ninety-nine patients were included (48 FNF and 51 ORIF). After 10 years 75% (33/44) of patients in the FNF group required no further follow up versus 81% (39/48) in the ORIF group. Radiographically at 2 years post-injury, there was no statistically significant difference between groups for development of osteoarthritis (p=0.851). There was one tibio-talar fusion in each group secondary to osteoarthritis, but no statistically significant difference in overall re-operation rate (p=0.518). Fifty-one percent (n=50) of patients have so far returned patient reported outcome measures at a minimum of 10 years (Fibular nail n=23, plate fixation n=27). No significant difference was found between groups for the mean scores of Olerud and Molander Ankle Score (FNF 84.78 vs ORIF 84.07; p=0.883), the Manchester-Oxford Foot Questionnaire (MOXFQ) (FNF 89.54 vs ORIF 96.47; p=0.112), Euroqol-5D Index (FNF 0.88 vs ORIF 0.87; p=0.701) and Euroqol-5D Visual Analogue Score (FNF 77.30 vs ORIF 77.52; p=0.859). Conclusion. The current study illustrates that both methods of treatment result in a satisfactory long-term outcome with no difference in late complications or PROM scores at up to 10 years in patients under 65 years old, although the study is currently under powered

Background. Ankle fractures associated with diabetes experience more complications following standard Open-Reduction-Internal-Fixation (ORIF) than those without diabetes. Augmented fixation strategies namely extended ORIF and hind-foot-nail (HFN) may offer better results, and early weightbearing in this group. The aim of this study was to define the population of patients with diabetes undergoing primary fixation for ankle fractures. Secondarily, to assess the utilisation of standard and augmented strategies and the effect of these choices on surgical outcomes including early post-operative weight bearing and surgical complications. Methods. A national-multicentre retrospective cohort study was conducted between January to June 2019 in 56 centres (10 Major- Trauma-Centres and 46 Trauma-Units) in the United Kingdom; 1360 specifically defined complex ankle-fractures were enrolled. Demographics, fixation choice, surgical and functional outcomes were recorded. Statistical analysis was performed to compare high-risk patients with/without diabetes. Results. There were 316 patients in the diabetes cohort with mean age 63.9yrs (vs. 49.3yrs in non-diabetes cohort), and greater frailty score >4 (24% vs.14% (non-diabetes cohort) (p<0.03); 7.5% had documented neuropathy. In the diabetes cohort, 79.7% underwent standard ORIF, 7.1% extended ORIF and 10.2% a HFN compared to 87.7%, 3.0% and 10.3% in the non-diabetes cohort. Surgical wound complications after standard-ORIF were higher in the diabetes cohort (15.1% vs. 8.7%) (p<0.02) but patients with diabetes who underwent augmented techniques showed little difference in surgical outcomes/complications to non-diabetes, even though early-weight- bearing rates were greater than standard-ORIF. Conclusion. Ankle fractures in diabetes occur in older, frailer patients; whilst lower than expected neuropathy rates suggest a need for improved assessment. Augmented surgical techniques may allow earlier weight-bearing without increasing complications in keeping with modern guidelines in ankle fracture management

Aims. This study aimed to compare the outcomes of two different postoperative management approaches following surgical fixation of ankle fractures: traditional cast immobilization versus the Early Motion and Directed Exercise (EMADE) programme. Methods. A total of 157 patients aged 18 years or older who underwent successful open reduction and internal fixation (ORIF) of Weber B (AO44B) ankle fractures were recruited to this randomized controlled trial. At two weeks post-surgical fixation, participants were randomized to either light-weight cast-immobilization or the EMADE programme, consisting of progressive home exercises and weekly advice and education. Both groups were restricted to non-weightbearing until six weeks post-surgery. The primary outcome was assessed using the Olerud-Molander Ankle Score (OMAS) questionnaire at 12 weeks post-surgery, with secondary measures at two, six, 24, and 52 weeks. Exploratory cost-effectiveness analyses were also performed. Results. Overall, 130 participants returned their 12-week OMAS questionnaires. The mean OMAS was significantly higher in the EMADE group compared with the immobilized group (62.0 (SD 20.9) vs 48.8 (SD 22.5)), with a clinically meaningful mean difference of 13.2 (95% CI 5.66 to 20.73; p < 0.001). These differences were maintained at week 24, with convergence by week 52. No intervention-related adverse events, including instability, were reported. Conclusion. The EMADE programme demonstrated an accelerated recovery compared to traditional six-week cast immobilization for those who have undergone ORIF surgery to stabilize Weber B (AO44B) ankle fractures. The study found the EMADE intervention to be safe. Cite this article: Bone Joint J 2024;106-B(9):949–956

Background. Supination-external rotation (SER) injuries make up 80% of all ankle fractures. SER stage 2 injuries (AITFL and Weber B) are considered stable. SER stage 3 injury includes disruption of the posterior malleolus (or PITFL). In SER stage 4 there is either medial malleolus fracture or deltoid injury too. SER 4 injuries have been considered unstable, requiring surgery. The deltoid ligament is a key component of ankle stability, but clinical tests to assess deltoid injury have low specificity. This study specifically investigates the role of the components of the deep deltoid ligament in SER ankle fractures. Aim. To investigate the effect of deep deltoid ligament injury on SER ankle fracture stability. Methods. Four matched pairs (8 specimens) were tested using a standardised protocol. Specimens were sequentially tested for stability when axially loaded with a custom rig with up to 750N. Specimens were tested with: ankle intact; lateral injury (AITFL and Weber B); additional posterior injury (PITFL); additional anterior deep deltoid; additional posterior deep deltoid; lateral side ORIF. Clinical photographs and radiographs were recorded. In addition, dynamic stress radiographs were performed after sectioning the deep deltoid and then after fracture fixation to assess tilt of the talus in eversion. Results. All specimens with an intact posterior deep deltoid ligament were stable when loaded and showed no talar tilt on dynamic assessment. Once the posterior deep deltoid ligament was sectioned there was instability in all specimens. Surgical stabilisation of the lateral side prevented talar shift but not talar tilt. Conclusion. If the posterior deep deltoid ligament is intact SER fractures may be managed without surgery in a plantigrade cast. Without immobilisation the talus may tilt, risking deltoid incompetence

Introduction. Following publication of the Ankle Injury Management (AIM) trial in 2016 which compared the management of ankle fractures with open reduction and internal fixation (ORIF) versus closed contact casting (CCC), we looked at how the results of this study have been adopted into practice in a trauma unit in the United Kingdom. Methods. Institutional approval granted to identify eligible patients from a trauma database. 143 patients over 60 years with an unstable ankle fracture between 2017 and 2019 (1 year following publication of the AIM trial) were included. Open fractures, and patients with insulin-dependent diabetes or peripheral vessel disease were excluded (as per AIM criteria). Radiographs were reviewed for malunion and non-union. Clinical notes were reviewed for adverse events. Minimum follow up was 24 months. Results. Of the 143 patients, 42 patients (29.4%) received a moulded cast with a return to theatre rate of 21.4%, malunion rate of 30.1%, and infection or wound problem rate of 4.8%. When the exact phrase “close contact cast” was specified in 21 patients (14.7%), there was a 19.0% return to theatre rate, 28.6% malunion rate, and a 4.8% infection or wound problem rate. 101 patients (70.6%) had ORIF with a return to theatre rate of 10.9%, malunion rate of 5.0%, and infection or wound problem rate of 13.9%. Discussion. Our results show a high rate of complication with cast management of unstable ankle fractures in this older population. This was improved where CCC was specified, but remains higher even than those published in the AIM trial. Whilst there is certainly a role for CCC in carefully selected patients, we would advise caution in the widespread adoption of a close contact casting technique

Introduction. We report the functional outcome and survivorship of the Hintegra Total Ankle Replacement (TAR), in consecutive cases by multiple surgeons in a single UK institution. Between 2010–2014 the Hintegra TAR held 7.1% UK market share and surgeons should be aware of failure mechanisms. Methods. We conducted a retrospective review of prospectively collected data for 70 consecutive Hintegra TAR cases in a single institution between 2010–2014. Data collected included patient demographics, complications, reoperations, patient reported outcome measures (PROMS: AOS, MOX-FQ, pain VAS) and patient satisfaction. Results. The 70 patients (54 male/ 16 female) had an average age of 69 (range 48–84 years). Mean follow up was 76 months (range 60–04), 10 patients died during the follow up. Implant survivorship was 81.4% at most recent follow up. The commonest radiographic finding was periprosthetic cysts (n=28, 40%), size range (7–40mm), location of cysts: isolated talus (n=14), isolated tibia (n=6), mixed (n=8). 10 failed TARs were revised to Inbone TAR at a mean of 48 months (range 9–69). 3 Failed TARs were revised to arthrodesis (2 tibiotalar fusions, 1 hindfoot nail). 11 patients required reoperation with implant retention: 8 periprosthetic cyst debridement and grafting at a mean of 61 months (range 27–91), 1 lateral gutter debridement and 1 periprosthetic fracture ORIF. PROMS data was available for all patients. Overall patients showed marked improvement in functional outcome scores between pre-operative and final follow up questionnaires. Mean pre-op AOS: 62, MOX-FQ: 68 and pain VAS: 67.5 with mean final follow up scores of: AOS: 35, MOX-FQ: 36 and pain VAS: 30. Conclusion. Our experience demonstrates improved PROMS following ankle arthroplasty for patients with a mean follow up of 6.4 years. Implant survivorship is similar to other TAR studies. We have identified a high incidence of periprosthetic cysts and would recommend ongoing surveillance of these patients

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

Introduction. Ankle fractures are common injuries presenting to trauma departments and ankle open reduction and internal fixation (ORIF) is one of the first procedures targeted in early orthopaedic training. Failure to address the fracture pattern with the appropriate surgical technique and hardware may lead to early failure resulting in revision procedures or premature degenerative change. Patients undergoing revision ORIF are known to be at much greater risk of complications, and many of these secondary procedures may be preventable. Method. A retrospective analysis of all patients attending our unit for ankle ORIF over a two year period was undertaken. Patients were identified from our Bluespier database and a review of X rays was undertaken. All patients undergoing re-operation within eight weeks of the primary procedure were studied. The cause of primary failure was established and potential contributing patient and surgical factors were recorded. Results. 236 patients undergoing ankle ORIF were identified. 13 patients (5.5%) returned to theatre for a secondary procedure within eight weeks. Within this group, 7 (54%) patients returned for treatment of a neglected or under treated syndesmotic injury, 3 (23%) for complete failure of fixation, 2 (15%) with wound problems and 1 (8%) for medial malleoulus mal-reduction. Of the patient group, 5 (38%) were known type 2 diabetics. Consultants performed 2 (15%) of procedures, supervised registrars 5 (39%) and unsupervised registrars 6 (46%) operations. Conclusion. Errors are being made at all levels of training in applying basic principles such as restoring fibula length and screening the syndesmosis intra-operatively. Appropriate placement and selection of hardware is not always being deployed in osteopenic bone resulting in premature failure of fixation and fracture patterns are not being fully appreciated. Patients are undergoing preventable secondary procedures in the operative treatment of ankle fractures

Background. There is an increasing acceptance that the clinical outcomes following posterior malleolar fractures are less than satisfactory. In our previous multicenter study (Powell, BOFAS 2016) we showed that the Olerud-Molander Ankle Score (OMAS) was 79 for unimalleolar fractures and 65 for bi malleolar fractures, however it dropped significantly to 54 in trimalleolar fractures. In creating a treatment guiding classification, we report our results in a system change in management of posterior malleolar fractures in our unit. Method. All fractures were classified according to Mason and Molloy classification (BOFAS 2015, FAI 2017) based on CT scans obtained pre-operatively. This dictated the treatment algorithm. Type 1 fractures underwent syndesmotic fixation. Type 2A fractures underwent ORIF through a posterolateral incision, and type 2B and 3 fractures underwent ORIF through a posteromedial incision. The patient remained NWB for 6 weeks postoperative. Data was collected from December 2014 to July 2017. Results. Patient related outcome measures were obtained in 50 patients with at least 6 month follow up (mean 18 months). According to Mason and Molloy classification there were 17 type 1, 12 type 2A, 10 type 2B and 11 type 3. The mean OMAS for type 1 was 75.9 (Range 30–100, SD 18.4), type 2A 75.0 (range 35–100, SD 21.3), type 2B 74.0 (range 55–100, SD 13.7) and type 3 70.5 (Range 35–100, SD 17.1). An increase in OMAS of 4 is clinically significant. Conclusion. We have been able demonstrate an improvement in OMAS for all posterior malleolar fractures with the treatment algorithm applied using the Mason and Molloy classification. Compared to our previous study we have successfully increased our OMAS scores to what would be expected from unimalleolar fractures. Mason and Molloy type 3 fractures have marginally poorer outcomes, which correlates with a more significant injury, however this does not reach statistical significance

Aims

The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant.

Aims

To identify a core outcome set of postoperative radiographic measurements to assess technical skill in ankle fracture open reduction internal fixation (ORIF), and to validate these against Van der Vleuten’s criteria for effective assessment.

Ankle fractures account for 10% of all fractures. Most deformed looking ankles are manipulated in the emergency departments (ED) on clinical judgement in order to improve the outcome and avoid skin complications. It is accepted that significantly displaced ankle injuries with neurovascular (NV) compromise or critical skin should be reduced prior to imaging. However, is it really possible to understand the injury to an ankle without an x-ray or other imaging? The other possible injuries around the ankle, presenting with swelling and deformity of the ankle region, may include a ligamentous, talar, subtalar, Chopart joint or calcaneal injury. Does the risk of waiting for the imaging outweigh the benefit of manipulation of an undiagnosed injury?. This prospective study involved the analysis of all patients with ankle injuries referred to orthopaedics between November 2009 and February 2010. Results: Over the audited period 100 referrals were identified (43 male, 57 female). The average age was 50.4 years (range 5–89). Only 2% of fractures were open. Manipulation in the ED was performed for 44% of patients. Of these, 39% (17 cases) were manipulated and supported in plaster slab without an initial x-ray; 3 due to vascular deficit, 2 due to critical skin and 12 with no documented reason!. Re-manipulation in the ED as well as definitive open reduction and internal fixation (ORIF) were significantly lower in those patients who had an x-ray prior to manipulation (p < 0.05). ORIF was performed in 68% of all patients. Importantly, 80% of ankles manipulated in ED went on to have ORIF which was significantly higher than the 47% in the non-manipulation cohort (p < 0.05). We conclude that taking ankle injury radiographs prior to any attempt at manipulation, in the absence of NV deficit or critical skin, will constitute best practice

Introduction. Comminuted mid-foot fractures are uncommon. Maintenance of the length and alignment of the medial column, with restoration of articular surface congruity, is associated with improved outcomes. Conventional surgery has utilised open or closed reduction with K-wire fixation, percutaneous techniques, ORIF, external fixation or a combination of these methods. In 2003 temporary bridge plating of the medial column was described to reconstruct and stabilise the medial column. The added advantage of locking plates is the use of angle-stable fixation. We present our experience with temporary locking plates in complex mid-foot fractures. Materials and methods. Prospective audit database of 12 patients over a 6 year period (2003-2009). 5 males 7 females mean age 41.9. Mechanism of injury: 11 high-energy injuries (6 falls from height, 5 RTCs), 1 low energy injury. Fracture type: All involved the medial column - 12 fracture dislocations of the medial column. 4 concomitant injuries to the lateral column. All underwent ORIF, realignment, and stabilisation with locking plates across the mid-foot. Results. Median length of time to plate removal: 3 months (range 2-6). Prior to removal of the metalwork, there was no loss of reduction, no infections, and no implant breakage. 10 out of 12 required plate removal at 3 months. Long-term follow-up (Mean 12.4 months, range 4-32): 11 have minimal symptoms of swelling or discomfort from the midfoot which does not restrict their ADLs, whilst 1 patient developed post-traumatic arthritis with medial arch collapse. No secondary procedures following plate removal. The two patients with the plate in-situ were asymptomatic with regards to the metalwork at final follow-up. Conclusion. Locking plates provide adequate stabilisation following open reduction and internal fixation of complex and unstable midfoot fracture dislocations. However, the majority will require removal of the metalwork. Following removal of the metalwork, satisfactory length and alignment, and stability of the midfoot, is maintained

Introduction. Isolated Weber B fractures usually heal uneventfully but traditionally require regular review due to the possibility of medial ligament injury allowing displacement. Following recent studies suggesting delayed talar shift is uncommon we introduced a functional treatment protocol and present the early results. Methods. 141 consecutive patients presenting acutely with Weber B fractures without talar shift between January and December 2015 were included. Patients were splinted in a removable boot and allowed to weight bear. ED notes and radiographs were reviewed by an Orthopaedic consultant. Patients without signs of medial injury were discharged with an information leaflet and advice. If signs of medial ligament injury were noted or the medial findings were not documented the patient was reviewed in fracture clinic at 4 weeks post-injury. If talar shift developed the patient was to be converted to operative treatment. Olerud and Molander scores were collected between 6 and 12 months post-injury. Results. 65 of 89 patients with signs of medial ligament injury or no documented medial findings attended fracture clinic. Of 51 patients without signs of medial ligament injury 23 were discharged according to protocol and 28 patients attended fracture clinic. One discharged patient re-accessed care. Of 93 patients reviewed in the fracture clinic none developed delayed talar shift. One underwent delayed ORIF for ongoing fibula discomfort and the remainder continued with non-operative treatment. 99 (70%) patients provided outcome scores. The mean score at a minimum of 6 months follow-up was 87 and the median score was 100. No significant difference was found between treatment arms. The scores were comparable to those in the published literature. Conclusion. We conclude the risk of delayed talar shift is low and satisfactory outcomes can be safely achieved with our functional protocol. Additional tests/imaging to establish the integrity of the medial ligament may be unnecessary

Introduction. We describe a novel single incision approach and its safety in the largest reported series of Lisfranc injuries to date. Via separate subcutaneous windows it is possible to access the medial three rays of the foot for bridge plating, without the concern of narrow skin bridges between multiple incisions. Methods. A retrospective review identified all 150 patients who underwent a Lisfranc ORIF via the modified dorsal approach at the Royal Melbourne Hospital between January 2011 and June 2016. All patients were operated by a single surgeon. Removal of metalwork (ROM) was routinely undertaken at six months post-operatively via the same incision. Medical recored were reviewed to record patient demographics, mechanism of injury and surgical details. Outpatient notes were reviewed to identify wound-related complications including; delayed wound healing, superficial infection, wound dehiscence, deep infection, complex regional pain syndrome (CRPS), neuroma and impaired sensation. Median follow-up was 1012 days (range 188–2141). Results. Median age was 37 years (19–78). 110 (73%) patients were male. Mechanism of injury was: motor vehicle accident (37%), motor bike accident (19%) and fall (18%). 24 (16%) injuries were open, 5 of which required soft tissue reconstruction at the primary surgery. A total of 34 wound related complications occurred (22%); superficial infection (14), delayed wound healing (7), wound dehiscence (5), CRPS (4), impaired sensation (3), neuroma (1). Re-operation was necessary in the 5 patients who experienced wound dehiscence; 4 requiring split skin grafts and 1 requiring a free flap. Crush injuries were 10 times more likely to have wound complications than those sustained in motor vehicle accidents. Patients undergoing ROM were more likely to have wound complications than those who did not. Conclusion. The modified dorsal approach using subcutaneous windows to access the midfoot joints offers a viable alternative to existing approaches

Aims

This is a multicentre, non-inventor, prospective observational study of 503 INFINITY fixed bearing total ankle arthroplasties (TAAs). We report our early experience, complications, and radiological and functional outcomes.

Introduction:. Early stabilization has the potential to expedite early return to function and reduce hospital stay thus reducing cost to health care. A clinical audit was performed to test the hypothesis that early surgical stabilization lowers the rate of soft tissue complications and is not influenced by choice of distal fibular implants used for stabilization of ankle fractures. Methods:. All surgically treated adult patients with isolated unstable ankle fracture were included from April 2012 to April 2013 at a MTC in UK. Patients with poly-trauma were excluded. All patients underwent a standard surgical protocol: aim for early definitive surgical fixation (ORIF) within 24 hours however if significantly swollen than temporary stabilization with an external fixation followed by a staged definitive fixation. Results:. In total 172 consecutive unstable ankle fractures were included in one-year study period. Definitive fixation (ORIF) was achieved in 91% patients with only 9% patients required temporary stabilization with external fixation. Fibular locking plates were used in 59(38%) patients compared to conventional one-third tubular plates in 91(60%) patients. In ORIF group 42% (73) patients were operated within 24 hours of admission whilst 58% (83) under went early fixation after 24–72 hours. At one year follow up complications were recorded in 18(11%) patients including metal irritation requiring removal of implant in 6(4%) patients. Wound complications and deep infection leading to a further surgical procedure in 8(5%) patients. There was no statistical difference between complication rates (p=0.016) in early versus delayed fixation groups. Fibular locking plates were associated with higher soft tissue complications (13%) as compared with conventional plates (2%) (p=0.004). Conclusion:. Our study showed that the timing of the surgery has less influence on the complications of the ankle fracture fixation. However choice of implants requires careful consideration and we suggest caution against use of current fibular locking plates
