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. 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.Introduction:
