Introduction. Total contact casting (TCC) is one of the most commonly utilized modalities in the management of diabetic feet. We undertook a retrospective review to determine the prevalence of symptomatic VTE events in patients treated in a weight bearing TCC in our diabetic foot unit, and to formulate guidelines for VTE prophylaxis. Methods. Electronic records were reviewed to identify all patients treated in a TCC between 2014 and 2021. Data collection included patient demographics, comorbidities, period of immobilization in TCC, the incidence of VTE events, and any VTE prophylaxis prescribed during their period in TCC. Results. 549 patients were identified who had at least one episode of TCC. Mean age was 67 years (range 28 to 94 years) and the mean duration in cast was 10.2 weeks (range 0.3–46 weeks). Only 6 patients (1.1%) were prescribed chemical thrombo-prophylaxis during their period in TCC. Mean body mass index (BMI) for these patients was 32.3 (Range 18.4–58.9). Other significant comorbidities: 81% (n-444) of patients had associated cardio-vascular comorbidities; 54 % (n-296) had renal comorbidities including 22% (n-121) having had dialysis and 4.2% (n-23) with renal transplants. Eight of the 549 patients (1.5%) had suffered a VTE event of which only 2 (0.36%) were during the period of immobilization in TCC. One was a symptomatic DVT (0.18%) and the another was an asymptomatic (incidental) finding of pulmonary embolism (PE). There was no mortality related to the VTE episodes. Conclusion. NICE guidelines state that one should “Consider pharmacological VTE prophylaxis for patients with lower limb immobilization”. Our study finds that patients treated in a weight bearing TCC do not require routine pharmacological VTE prophylaxis, in spite of an extended period of lower limb immobilization and significant medical comorbidities

Aims

This study evaluated the effect of treating clinician speciality on management of zone 2 fifth metatarsal fractures.

Introduction. Greater length of stay (LOS) after elective surgery results in increased use of health care resources and higher costs. Within the realm of foot and ankle surgery, improved perioperative care has enabled a vast majority of procedures to be performed as a day surgery. The objective of this study was to determine the perioperative factors that predict a prolonged LOS after elective ankle replacement or fusion. Methods. Data was prospectively collected on patients undergoing either an ankle fusion or ankle replacement for end-stage ankle arthritis at our institution (2003–2010). In the analysis, LOS was the outcome and age, sex, physical and mental functional scores, comorbid factors, ASA grades, type and length of operation and body mass index (BMI) were potential perioperative risk factors. Univariate and multivariate generalized linear regression models with gamma distribution and log link function were conducted. Results. A total of 336 patients were included in the study. The median LOS was 76 hours with interquartile range of 52.5–97. Using regression analysis, we showed aging, female gender, a higher ASA score, multiple medical comorbidities, rheumatoid arthritis, a lower score in the physical component (PCS) and general health domain (GH) of SF-36, open surgery and an increased length of surgical time were all significantly associated with an increased LOS. Conversely, obesity, the SF-36 Mental Component Score and the date of admission were noninfluential of LOS. A predictive model was also developed using these same risk factors. Conclusions. Increased age, female gender, high ASA scores, low SF-36 GH and PCS scores, increased number of medical comorbidities, rheumatoid arthritis and open surgery were all factors that increased LOS significantly after ankle fusion or ankle replacement. This group of patients may warrant better education and more focused perioperative care when it comes to designing care pathways and allocating health care resources

Aims

When a total ankle arthroplasty (TAA) fails, it can be converted to a fusion or a revision arthroplasty. Despite the increasing numbers of TAAs being undertaken, there is little information in the literature about the management of patients undergoing fusion following a failed TAA. The primary aim of this study was to analyze the survival of fusions following a failed TAA using a large dataset from the National Joint Registry (NJR).

Aims

The number of revision total ankle arthroplasties (TAAs) which are undertaken is increasing. Few studies have reported the survival after this procedure. The primary aim of this study was to analyze the survival of revision ankle arthroplasties using large datasets. Secondary aims were to summarize the demographics of the patients, the indications for revision TAA, further operations, and predictors of survival.

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

Despite the increasing numbers of ankle arthroplasties, there are limited studies on their survival and comparisons between different implants. The primary aim of this study was to determine the failure rates of primary ankle arthroplasties commonly used in the UK.

Aims

This scoping review aims to identify patient-related factors associated with a poorer outcome following total ankle arthroplasty (TAA).

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.

Aims

The aim of this study was to capture 12-month outcomes from a representative multicentre cohort of patients undergoing total ankle arthroplasty (TAA), describe the pattern of patient-reported outcome measures (PROMs) at 12 months, and identify predictors of these outcome measures.

Aims

To our knowledge, there is currently no information available about the rate of venous thromboembolism (VTE) or recommendations regarding chemoprophylaxis for patients whose lower limb is immobilized in a plaster cast. We report a retrospective case series assessing the rate of symptomatic VTE in patients treated with a lower limb cast. Given the complex, heterogeneous nature of this group of patients, with many risk factors for VTE, we hypothesized that the rate of VTE would be higher than in the general population.

Aims

We report the long-term clinical and radiological outcomes of a consecutive series of 200 total ankle arthroplasties (TAAs, 184 patients) at a single centre using the Scandinavian Total Ankle Replacement (STAR) implants.

Aims

Limb salvage for diabetic foot infections often require multiple procedures. Some patients will eventually end up with below knee amputation (BKA) when all limb salvage attempts fail. We seek to study the patients’ ability to return to normal life, functional status, prosthesis usage and perspectives on multiple limb salvage procedures that culminated in BKA to review if they would undertake a similar path if their situation was repeated.

Aims

Hindfoot arthrodesis with retrograde intramedullary nailing has been described as a surgical strategy to reconstruct deformities of the ankle and hindfoot in patients with Charcot arthropathy. This study presents case series of Charcot arthropathy patients treated with two different retrograde intramedullary straight compression nails in order to reconstruct the hindfoot and assess the results over a mid-term follow-up.

Limited forefoot amputation in diabetic patients with osteomyelitis is frequently required. We retrospectively reviewed diabetic patients with osteomyelitis, an unhealed ulcer and blood pressure in the toe of > 45 mmHg who underwent limited amputation of the foot with primary wound closure. Between 2006 and 2012, 74 consecutive patients with a mean age of 67 years (29 to 93), and a median follow-up of 31 months, were included. All the wounds healed primarily at a median of 37 days (13 to 210; mean 48). At a median of 6 months (1.5 to 18; mean 353 days), 23 patients (31%) suffered a further ulceration. Of these, 12 patients (16% of the total) required a further amputation.

We conclude that primary wound closure following limited amputation of the foot in patients with diabetes is a safe and effective technique when associated with appropriate antibiotic treatment.

Diagnostic and operative codes are routinely collected for every patient admitted to hospital in the English NHS. Data on post-operative complications following foot and ankle surgery have not previously been available in large numbers. Data on symptomatic venous thromboembolism events and mortality within 90 days were extracted for patients undergoing fixation of an ankle fracture, first metatarsal osteotomy, hindfoot fusions and total ankle replacement over a period of 42 months. For ankle fracture surgery (45 949 patients), the rates of deep-vein thrombosis (DVT), pulmonary embolism and mortality were 0.12%, 0.17% and 0.37%, respectively. For first metatarsal osteotomy (33 626 patients), DVT, pulmonary embolism and mortality rates were 0.01%, 0.02% and 0.04%, and for hindfoot fusions (7033 patients) the rates were 0.03%, 0.11% and 0.11%, respectively. The rate of pulmonary embolism in 1633 total ankle replacement patients was 0.06%, and there were no recorded DVTs and no deaths. Statistical analysis could only identify risk factors for venous thromboembolic events of increasing age and multiple comorbidities following fracture surgery.

Venous thromboembolism following foot and ankle surgery is extremely rare, but this subset of fracture patients is at a higher risk. However, there is no evidence that thromboprophylaxis reduces this risk, and these national data suggest that prophylaxis is not required in most of these patients.

We report an audit of 208 patients with a mean age of 39 years (16 to 65) attending the Orthopaedic Assessment Unit at the Wellington Hospital between January 2006 and December 2007 with an injury of the tendo Achillis requiring immobilisation in a cast. Information on assessment of venous thromboembolism (VTE) risk, prophylactic measures and VTE events for all patients was obtained from the medical records. A VTE risk factor was documented in the records of three (1%) patients. One of the 208 patients received aspirin prophylaxis; none received low molecular weight heparin. In all, 13 patients (6.3%, 95% confidence interval 3.4 to 10.5) developed symptomatic VTE during immobilisation in a cast, including six with a distal deep-vein thrombosis (DVT), four with a proximal DVT, and three with a confirmed pulmonary embolus. This incidence of symptomatic VTE is similar to that reported following elective hip replacement.

We propose that consideration is given to VTE prophylaxis during prolonged immobilisation of the lower limbs in a cast, to ensure that the same level of protection is provided as for patients undergoing elective hip replacement.
