Coxarthrosis following Traumatic Posterior Dislocation of the Hip*

ABSTRACT: One hundred and twenty-seven hips in 125 adults were treated for traumatic posterior dislo-cation during a period of two decades. Ninety-eight pa-tients (100 hips) were available for follow-up exami-nation at a minimum of five years (average, fourteen years) after injury. By both clinical and radiographic criteria eighty hips (80 per cent) had an excellent or good result. Forty-two per cent of the hips that were reduced more than six hours after the dislocation had an excellent or good result and 88 per cent of those that were reduced within six hours after dislocation had an excellent or good result. Thirty-one per cent of the hips with a Grade-III dislocation had an excellent or good result, as com-pared with 90 per cent of those with a Grade-I dislo-cation. Twenty-two per cent of the hips with an excellen
