Diabetes is bad, common and diabetic foot ulcers (DFU) once established lead to high rates of amputation. In Nottingham our standard management for infected diabetic foot ulcers is surgical debridement, microbiological sampling, packing with gentamicin beads and targeted antibiotic therapy. Recently we have switched to packing with Stimulan, which is a purified synthetic calcium sulphate compound that can be mixed with patient appropriate antibiotics, is biodegradable and delivers better elution characteristics compared to gentamicin beads. To assess the efficacy of Stimulan compared to Gentamicin beads in the surgical management of infected diabetic foot ulcers.Background
Aim
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. 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.Introduction:
Methods:
We report the outcomes of salvage procedures in total ankle replacement (TAR) in a single surgeon series. This study was a retrospective review of patients who had undergone salvage procedures with tibio-talo-calcaneal (TTC) fusion for failed TAR over a period from 1999–2013 in a single centre. In this period, 317 TAR were performed of which 11 have failed necessitating conversion to TTC fusion. Clinical documentation and radiographs were reviewed for cause of failure, type of graft for fusion, time to radiological/clinical union and complications including further surgeries.Introduction:
Methods:
Total ankle replacement is a recognised treatment for disabling end stage ankle arthritis and an alternative to arthrodesis, although results are not yet comparable to other joint replacements. This has stimulated a constant evolution in design of implants and instrumentation. The Nottingham Foot and Ankle Unit used the STAR until 2005, when it switched to Mobility, due to the perceived advantages of less bone resection, improved instrumentation and potentially less polyethylene insert wear. The aim of this study is to report the unit's results and review the different outcomes between the two ankle replacements used. A retrospective analysis of all total ankle replacements carried out by the foot and ankle unit at Nottingham City Hospital between March 1999 and June 2013. Post operative complications, associated reoperations and revisions were recorded. The American Orthopaedic Foot and Ankle Score (AOFAS), Foot Function Index (FFI), European five dimension quality of life scores (EQ-D5) and patient satisfaction was independently assessed at each follow up visit. Other ankle replacements or those performed elsewhere or with less than 12 month follow up were excluded.Introduction:
Methods:
Periprosthetic cyst formation following ankle replacement, requiring revision surgery, has previously been reported. The exact pathogenesis of cyst formation is unclear but considered to be due to a combination of biological and mechanical factors. Our objective was to review the incidence of periprosthetic cyst formation following Mobility ankle replacement and their outcome. We reviewed all the Mobility ankle replacements performed by the senior author from Oct 2005 till May 2012. Serial radiographs were reviewed to identify the presence of cystic lesions in the tibia or the talus.Introduction
Patients and methods
With increasing numbers of primary total ankle replacements being performed, the number of revision ankle surgeries is expected to rise also. We present the results of the revision procedures for failed Scandinavian total ankle replacements. We retrospectively reviewed all the Scandinavian TAR done by the senior author from March 1999 till Jan 2006. Patients who underwent revision surgery were identified and their data was collected including indications for revision surgery, procedure performed, symptoms and the overall outcome.Introduction
Patients and methods
We carried out 123 consecutive total ankle replacements in 111 patients with a mean follow-up of four years (2 to 8). Patients with a hindfoot deformity of up to 10° (group A, 91 ankles) were compared with those with a deformity of 11° to 30° (group B, 32 ankles). There were 18 failures (14.6%), with no significant difference in survival between groups A and B. The clinical outcome as measured by the post-operative American Orthopaedic Foot and Ankle Surgeons score was significantly better in group B (p = 0.036). There was no difference between the groups regarding the post-operative range of movement and complications. Correction of the hindfoot deformity was achieved to within 5° of neutral in 27 ankles (84%) of group B patients. However, gross instability was the most common mode of failure in group B. This was not adequately corrected by reconstruction of the lateral ligament. Total ankle replacement can safely be performed in patients with a hindfoot deformity of up to 30°. The importance of adequate correction of alignment and instability is highlighted.
