Abstract
In a prospective study of 205 consecutive patients undergoing surgical stabilisation of acute pelvic and/or acetabular fractures, the incidence of proximal deep vein thrombosis (DVT) was 9.2%, pulmonary embolism (PE) was 1.9% and fatal PE 0.5%.
Use of a DVT prophylaxis protocol, using a low molecular weight heparin (LMWH), administered within 24 hours of injury or achieving haemodynamic stability, was associated with a significantly lower incidence of thromboembolism (p=0.036). Increased rates of thromboembolism were associated with longer delays to surgery (p=0.013), delays to mobilisation of the patient post-operatively (p=0.017), delay in starting chemoprophylaxis (p=0.039) and higher injury severity scores (p=0.042).
Patient age, sex, Glasgow Coma Scale and fracture classification were not associated with the development of thromboembolic complications.
One hundred and thirty four patients had a pre-operative venous Doppler, seven patients had a proximal DVT identified of which six patients had a preoperative inferior vena caval filter applied and underwent successful surgical fracture stabilisation. Five filters were unable to be removed postoperatively and the patients remain on lifelong warfarin.
A DVT prophylaxis protocol using LMWH is reported that is safe and effective.
