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.

Introduction:. The National institute of Health and Clinical Excellence (NICE) guidelines for thromboprophylaxis following lower limb surgery and plastercast immobilisation recommend pharmacological prophylaxis be considered until the cast is removed. These guidelines have been extrapolated from data for hip and knee arthroplasty, and trauma studies. Recent studies have questioned the validity of these guidelines. At Portsmouth, low molecular weight heparin (LMWH) is prescribed for 14 days following surgery in high risk patients. The protocol predates the most recent NICE guidance. We set out to investigate whether this was a safe method of thromboprophylaxis following elective hindfoot surgery. Methods:. A retrospective audit of all patients undergoing hindfoot surgery between 01/01/10 and 31/12/12 was performed. All patients were immobilised in a POP backslab and prescribed 14 days of LMWH. All patients were reviewed at 2 weeks and converted to a full cast or boot. Immobilisation was continued for between 6 and 12 weeks. A list of all patients who had undergone investigation for deep vein thrombosis at Queen Alexandra hospital from 01/01/10 to 28/03/13 was obtained from the VTE investigation department. The two lists were cross referenced to identify any DVTs occurring following hindfoot surgery and plastercast immobilisation. Results:. During the 3 years, 197 major hindfoot operations were performed in 194 patients. Mean age was 53 years (range18-82) and 94 males with 100 females. Two patients had confirmed deep vein thromboses; 1 patient at 13 days post op while receiving LMWH prophylaxis. Conclusion:. Symptomatic VTE following elective hindfoot surgery and post operative plaster cast immobilisation in our hospital is rare. There are no randomised controlled trials to guide thromboprophylaxis regimes following hindfoot surgery. Based on our results, our protocol appears to be effective and safe

Introduction. Patients who present with atypical foot pain in a non specific sensory distribution may benefit from having nerve conduction studies (NCS). The aim of this study was to confirm whether NCS is a useful tool. Methods. Between July 2005 and March 2011, 78 patients had NCS to investigate foot pain. The management following NCS was compared with the initial management plan. Results. Complete data was available for 60 patients, of whom 31 were male. The mean age at presentation was 54.4 years (range 18–89.7). Eighteen patients had bilateral symptoms. The predominant symptom was pain in 47 patients. Aching, burning, throbbing, shooting, pins and needles, proximal/distal radiation, numbness, and paraesthesia were also described in 23 patients. Twenty patients had a history of trauma and five developed symptoms following elective lower limb surgery. Eight patients had a cavovarus foot. There were 22 normal results. The NCS diagnosed peripheral nerve (13)/nerve root (8) pathology, Charcot-Marie-Tooth (1), amyotrophic lateral sclerosis (1), tarsal tunnel syndrome (3), and nonspecific neuropathy (12). Surgery was initially considered for 9 patients. Following a normal result, 4 out of 7 had surgery. One patient with an abnormal result proceeded to surgery. The NCS was abnormal in 70.1% (36/51) of patients who were for nonoperative management, 4 of whom proceeded to have surgery. None of the patients who had a normal NCS had an operation. Conclusion. NCS provided a diagnosis for 63.3% of the patients. Following NCS, the management plan changed in 44% of patients who were initially considered for surgery (4/9) and in 7.8% of patients who were initially considered for nonoperative management (4/51). This investigation is a useful adjunct in guiding the management of patients who present with atypical non specific foot pain
