A consecutive series of 19 patients (19 hips) with dysplastic hip were treaded at the Kumamoto Orthopaedic Hospital with curved periacetabular osteotomy, described by Naito et al., and followed up for a minimum of six months (average, 13 months). There were one male and 18 females. The average age at the time of operation was 40 years. The average acetabular head index was 96.6% postoperatively, compared with 68.3% preoperatively. The average Japanese Orthopaedic Society Hip Score improved from 70.5 points preoperatively to 90.7 points postoperatively. Eighteen out of the 19 patients were very satisfied with this procedure. There were no major complications, except in six patients who experienced sensory disturbance in the area of lateral femoral cutaneous nerve, which disappeared after several months.
