We reviewed 22 486 consecutive autopsy reports in a single District Ge
neral Hospital, from 1953 to 1992. Five hundred and eighty-one patient
s with fractures of the proximal femur (hip fracture) were identified.
Causes of death were correlated with timing of surgery and change of
clinical practice. Thromboembolic and haemorrhagic potential were anal
ysed. The principal causes of death after hip fracture were bronchopne
umonia, cardiac failure, myocardial infarction and pulmonary embolism.
Surgical intervention, within 24 h of injury significantly reduced de
ath from bronchopneumonia and pulmonary embolism. Early mobilization r
educed death from bronchopneumonia. Pulmonary embolism may be reduced
by prophylactic anticoagulation, but 17 per cent of patients are at ri
sk of haemorrhage, and mechanical methods seem safer in this populatio
n.
