A prospective study done over a 14 months period revealed an 8% incidence of proximal deep vein thrombosis after major orthopaedic surgical procedures. All patients were analysed by compression ultrasound, which was found to be a good modality to pick up this complication. This is a significant incidence of a potentially disastraous complication, and is contrary to the common view that DVT is rare in Asian populations. Routine prophylaxis is therefore recommended after major lower limb surgery.
