Sequelae of arthrodesis of the hip.

Twenty-two patients with unilateral arthrodesis of the hip were reviewed clinically and radiologically ten years or more after operation. There was evidence of degenerative disease in 63.6% of the contralateral hips, 68.2% of the ipsilateral knees and in 59.1% of the contralateral knees. Both knees were affected in 50% of cases. All the patients had some degree of backache. The incidence of these problems in contrast with previously reported series is discussed.
