Abstract:
[Objective]To evaluate the outcome of the Pemberton osteotomy for the treatment of developmental dysplasia of the hip (DDH) in older children. [Method]There were 21 children (24 hips) older than 7 years in our study , who received the Pemberton osteotomy, and combined with femoral shortening, derotational or varus osteotomies according to the level of dislocation, anteversion and neck-shalf angle of the femur. The average age at operation were 9 years and 7 months (range: 7~13.5 years).[Result]The mean follow-up were 5 years and 5 months. Eighteen hips achieved the excellent or good clinical results according to the McKay's clinical criteria. All of the hips got improvements of the Acetabular Index, Sharp Acetabular Angle, Center-Edge Angle and Acetabular Head Index. The average results were in the normal range. Eighteen hips got ⅠorⅡclass of the Severin’s radiographic classification.However, 9 hips were limited in the range of movement. Four hips got subluxation.Six hips developed avascular necrosis of the femoral head. Three hips got improved osteoarthritis.[Conclusion]The Pemberton osteotomy for the treatment of developmental dysplasia of the hip in older children can mostly achieve well-used, contained or concentric reduction hips, meanwhile need to reduce the complications.
