Surgery for pelvic or acetabular fractures carries a high risk of deep-vein thrombosis (DVT). Reports indicate that fondaparinux is a more effective thromboprophylactic agent than low molecular weight heparin (LMWH) after major orthopaedic surgery. We prospectively evaluated a new protocol for DVT prophylaxis using fondaparinux. One hundred and eight patients with pelvic or acetabular fractures were randomised to receive either fondaparinux or enoxaparin. Specific review points included the primary end-point of clinical deep vein thrombosis (DVT) or pulmonary embolism (PE) and any evidence of adverse effects such as bleeding or allergic reactions. Two patients that received enoxaparin were found to have a DVT (3%) and one patient died from a PE (1%). There was no documented DVT or PE in patients that received fondaparinux. The mean number of units of blood transfused was significantly higher in the enoxaparin group and this was significant post-operatively (p<0.05). The current study supports that post-operative fondaparinux, in patients with pelvic and acetabular fractures, is more effective and equally safe to enoxaparin.Patients and methods
