37 patients (8 male, 29 female) who had Chiari's pelvic osteotomy were reviewed to assess whether there was any difference in severity of surgical technique between male and female.Radiological measurements such as osteotomy angle, medial displacement of distal fragment of pelvic bone, medial and superior displacement of the femoral head were carried out in the antero-posterior X-ray pictures pre and post operatively and compared between the male and female.Results were radiologically evaluated in relation to CE angle, Sharp angle, Acetabular-Head index and approximate acetabular index and clinically evaluated using the JOA score.The degree of medial displacement of the distal fragment of the pelvic bone and improvement in CE angle in males were smaller than that in the female. There was no difference in the JOA score between male and females.The difficulty of medial displacement of the distal fragment in Chiari's operation in the male may be due to the anatomical structure of the male pelvic symphysis.
