 note = {Outcome of the intertrochanteric osteotomy combined with Chiari's pelvic osteotomy for the treatment of residual subluxation of congenitally displaced hip joint was reviewed from the clinical and radiological standpoint in regard to its preventability of worsening of osteoarthrotic change. One hundred and ten hips of eighty cases including seven males and seventy three females were followed up for two to seventeen years. Age at the surgery ranged from nine to fifty one years with the peaks at the second and the third decade. Results based on the assessment of clinical findings by the JOA hip score, and that of radiographic findings by JOA stage classification, also on Trendelenburg's sign and lower limb length discrepancy etc. are as follows. Hip score improved in 93 hips (85%), were unchanged in 13 hips (11%) and worsened in 4 hips (4%). Hip score and radiographic parameters were not worsened with longer period of follow up. Osteoarthrotic stage advanced in only 3 out of 110 hips and their causes were thought to be ascribed to technical failures. Postoperative upward migration of the femoral head over 3mm was seen only in 6 hips (5%), and 104 (95%) out of 110 hips stayed at the level the femoral head took just after the surgery. Age at surgery had no influence on the final hip score and radiographic parameters. The sphericity of the femoral head did not affect the final hip score. Muller-type varus osteotomy seemed better in improving Trendelenburg’s sign and in keeping the lower limb longer. These results lead to the conclusion that this combined operation is very effective in treating residual subluxation of the hip joint and can prevent development of osteoarthrosis to a certain extent.},
