Long term results of triradiate osteotomy of the pelvis. A follow-up study of 26 hips.
The authors reviewed 26 hips in 21 patients treated by triple osteotomy of the pelvis for the sequelae of congenital dysplasia or congenital dislocation of the hip. The minimum follow-up was 3 years, maximum 6 years. The clinical condition remained constant over this period. Pain, if present before operation, was either improved or disappeared. The Trendelenburg limp was either unchanged or improved. Reduction of range of hip movement was very rare. There was 0.5 cms lengthening of the leg compared with the pre-operative state. The post-operative radiographic parameters were unchanged over the follow-up period. These included the acetabular roof angle (C.E. angle), Hilgenreiner's roof angle, the neck/shaft angle, and anterior coverage of the femoral head. In about one third of the cases, however, there was deterioration in centralization.
