[Intertrochanteric osteotomy of the hip. Retrospective (10-18 years) clinical and radiologic study of 30...

The authors report on 28 patients with degenerative arthritis of the hip who underwent intertrochanteric osteotomy of the femur between 1970 and 1978. Two subjects were operated on bilaterally, bringing the total number of hips to 30. The follow-up period averaged 11.8 years. All patients underwent thorough clinical and radiographic examination as well as basography and computed electrogoniometry. The basographic examination consists of analysis of the temporal phases of gait, revealing angular abnormalities of the various joint components of the lower limbs which occur during walking. Processing the data by computer shows any anomaly present in the lower limbs. The results of treatment were good for the most part, and thorough functional examination by computer often revealed a poor radiographic result corresponding to a better clinical result.
