A retrospective study of the morbidity and mortality from deep vein thrombosis (DVT) and pulmonary embolus (PE) in 490 consecutive patients undergoing uncemented total hip replacement was carried out in a district general hospital. Special diagnostic tests for DVT and PE were not available. Patients were followed up for one year. There were three deaths in hospital and eight further deaths during the first year, all unrelated to DVT and PE. The clinical incidence of venous thromboembolism was 2.04%. While clinical diagnosis of venous thromboembolic disease probably underestimates its incidence, the figures for mortality are accurate. With every patient accounted for one year after operation, there were no deaths attributable to PE in this series.
