Despite evidence that effective regimens are available for the prevention of venous thrombosis in fractured hip patients, many centers do not use prophylaxis. In order to evaluate the efficacy and safety of heparin and graduated compression stockings, we conducted a cohort study of 55 consecutive fractures hip patients treated postoperatively with heparin, 5,000 U every 12 h, and graduated compression stockings. The rates of venous thromboembolism and bleeding were compared with an historical cohort from Hamilton. Before discharge, 51 patients underwent bilateral venography. Deep venous thrombosis (DVT) occurred in 10 of the 51 patients (incidence of 20%); three had proximal DVT (incidence of proximal DVT was 6%). DVT was seen in 29 of the 63 control patients (incidence 46%); 19 had proximal DVT (incidence of proximal DVT was 30%). The differences in the rates of DVT and proximal DVT are statistically significant (p less than 0.01). Bleeding occurred in one patient in the treatment group (incidence 2%) and five patients in the control group (incidence 8%). This study confirms that therapy with heparin and graduated compression stockings is effective, inexpensive, and convenient for the prevention of venous thrombosis in fractured hip patients and is associated with a low bleeding risk.
