Abstract
1. Three new cases of injury to main arteries at orthopaedic operations are described, and a follow-up of two previously described cases is given. The rarity of these accidents is a credit to those engaged in orthopaedic surgery, for many orthopaedic operations are done very close to great vessels, and often under the bloodless conditions of a tourniquet. Nevertheless, it is well to have the risk of great vessel injury in mind because such an accident, although rare, may be a serious threat to life or limb.
2. It is important to repair the damaged artery rather than ligate it because the risk to the growth or viability of the limb is lessened.
3. The aim should be a return to full function with as near normal a vascular anatomy as possible.
