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. 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).Introduction
Methods
Osteoarthritis in the foot and ankle affects approximately 30,000 patients annually in the UK. Evidence has shown that excess weight exacerbates foot pain, with significant increases in joint forces. However, despite the current trend for Clinical Commissioning Groups to ration surgery for obese patients, studies have not yet determined the effect of weight loss in obese patients with foot and ankle arthritis. Pilot study to investigate the effect of simulated weight loss on pain scores in obese patients with symptomatic foot and ankle arthritis.Introduction
Aim
Injections are used to treat a wide variety of pathologies. Our aim was to evaluate the efficacy and safety of foot and ankle injections in our clinic. We performed a retrospective review of notes and a telephone questionnaire audit into the clinical outcome of all patients who underwent an injection of the foot or ankle in a year. All procedures were performed in an out-patient setting by a consultant musculoskeletal radiologist using either ultrasound or X-ray guidance, with a minimum of two year follow-up. According to the pathology treated, the type of injection included depomedrone, hyaluronic acid and high volume saline injections.Introduction
Materials and methods
The saphenous nerve is classically described as innervating skin of the medial foot to the first MTP joint and thus is at risk in surgery to the medial ankle and foot. However, it has previously been demonstrated that the dorsomedial branch of the superficial peroneal nerve consistently supplies the dorsomedial forefoot, and therefore previous descriptions of the saphenous nerve maybe erroneous. We undertook a cadaveric study to assess the presence and variability of this nerve. 21 cadaveric feet were dissected from a level 5 cm above the medial Our study shows that the course of the saphenous nerve is highly variable, and when present usually terminates within 40mm of the ankle. Only 10% reach the first MTP joint. These findings are inconsistent with standard surgical text descriptions. The saphenous nerve is at risk in distal tibial screw placement and arthroscopy portal placement, and should be included in local anaesthetic ankle blocks in forefoot surgery, as a small proportion of nerves supply sensation to the medial forefoot.Discussion
