Abstract
Of the 20 patients who had a Charnley total hip replacement at Toyohashi National Hospital from May 1976 to Jan. 1983 17 (19 hips) were reevaluated over 6 months post-operatively about the prognosis, the complication and the operative procedure by personal examination and roentgenogram. These were also evaluated with hip score of Japan Or-thopedic Association and devided into two groups; (1) OA groups (2) RA groups.
Hip score of OA group improved more after operation than RA group. About pain, score increased well in both group. About ROM, remarkable improvement did not occur, but the score became worse slightly in RA groups. In only 4 hips (21.1%), perforation of acetabulum occurred at operation. Post operative complications were loosening of stem in 1 hip (6%), ectopic ossification in 6 hips (32%) and rupture of wires in 6 hips (32%).
The total replacement of the hip joint was performed for a 70-years-old man with OA who has ectopic ossification around the hip and loosening of stem due to ankylosis of hip joint.
When one compared the operative approach with and without osteotomy of greater tro-chanter, procedure with osteotmy was superior to one without osteotomy on follow-up study
