Four Cases of Mal-angulated Ankylosis of the Hip Joint, Suspected to be Gonococcal Arthritis (over fifty years of history)

Abstract

Four cases of mal-angulated ankylosis of the hip joint are reported on. The cause of ankylosis was suspected to be gonococcal arthritis.
All patients complained of low back pain and gonalgia. X-ray findings of the knee joints and lumbar spines showed severe degenerative deformities.
To correct these biomechanical disadvantages, arthroplasty using a Bateman UPF prosthesis have been performed in two cases. The others are still under observation. In the two patients treated, the results were excellent in one case and satisfactory in the other.
This procedure is of great value for such cases, especially in older patients complaining of low back pain or gonalgia.
