Vascular injury from external fixation: case reports

The incidence of vascular injury from external fixation of fractures was studied retrospectively in two surgical departments during the period 1985-1990. A total of 1231 fractures of the lower limb were treated. External fixation was used in the initial stabilization of 28 femoral and 93 tibial fractures. In this series of 121 fractures four iatrogenic vascular injuries were seen: two arterial thromboses with distal ischemia and two incidents of the formation of a false aneurysm with bleeding along a pin. The diagnosis was made by angiography. Surgical intervention was necessary in all four cases. In one patient the injury resulted in amputation of the distal portion of the foot.
