[Bilateral necrosis of the femoral head after use of working harness].

The case of a 42-year old man, who developed bilateral necrosis of the femoral head from traumatic causes is described. He hung in stirrups, working 4-6 hours a day decorating for three weeks, during which he complained of numbness, fatigue and radiating pain in both legs. X-rays and a bone scan were performed and bilateral femoral head necrosis was diagnosed, probably because of repeated temporary hypoxia of the femoral heads caused by the stirrups compressing the blood vessels.
