[Retrospective analysis of hip joint development after pericapsular Pemberton ilium osteotomy (modified by Tönnis) in conjunction with intertrochanteric corrective osteotomy].

A review of 45 hips with disorders (congenital dislocation of the hip, subluxation of the hip, hip dysplasia with or without secondary pertheslike changes) treated by pembertons pelvic osteotomy with femur osteotomy is shown. Its a followed-up about two years. Many of them (85%) had satisfactory roentgenographic results and its showed the effectiveness of this procedure. We think the best time for treatment is the age between 2 and 4 years.
