Periacetabular osteotomy through the Smith-Petersen approach.

Sixty-six hips in 58 patients that had undergone periacetabular osteotomy for residual acetabular dysplasia were available for clinical and radiographic followup at a minimum of 2 years (average, 4 years) after surgery. The final clinical results were graded as 17% excellent, 59% good, 12% fair, and 12% poor. No patient who met the ideal indications for surgery had a poor result during the study period. After reviewing the results, the authors remain positive regarding the periacetabular osteotomy and recommend it for individuals with hip pain and radiographic evidence of acetabular dysplasia.
