Abstract
In 27 patients operated on for unilateral coxarthrosis with the Chamley hip, the muscular strength and mobility were measured. Half the cases had a trochanteric osteotomy and half an anterolateral transgluteal approach. The abduction strength was normal after trochanteric osteotomy and weaker than normal in the nonosteotomized hips.
