Abstract

Objective: This study aims to present a review about complications of surgical treatment of Developmental Dysplasia of the Hip and comparing the kinds and ratios of two osteotomy technique (Salter Innominate Osteotomy and Pemberton Pericapsular Osteotomy).

Materials and Methods: Fifty-seven patients of 126 that had bilateral developmental dysplasia of the hip are the case series that had undewent to Salter Innominate Osteotomy for one hip and Pemberton Pericapsular Osteotomy for other hip by one surgeon in one stage.

Results: Avascular Necrosis ratio was 19.29% on hips with Salter Innominate Osteotomy, and 8.77% on hips with Pemberton Pericapsular Osteotomy. Salter Innominate Osteotomy  made lower limb discrepency with 0.47 cm mean in all patients. There were 17 general complications on hips with Salter Innominate Osteotomy (SIO) (14.91%) and 9 general complications on hip with Pemberton Pericapsular Osteotomy (PPO) (7.89%). As looking for general complications, SIO/PPO ratio were 1.8 (17/9).

Conclusion: By the comparing two osteotomy technique for complication ratios, SIO had two-fold of complications than PPO. SIO had 65% more complications as to PPO.
