We report our experience of Sugioka transtrochanteric valgus osteotomy (TVO) for hinge abduction in children. The advantages are early union with simple fixation and preservation of proximal femoral geometry. Lateral displacement of the greater trochanter improves abductor limp. A total of 24 patients of mean age 10.2 years underwent TVO. The neck shaft angle increased by mean 11.75 degrees. Migration index increased by mean 3.88%. Average limb length discrepancy at final follow-up was 10.8 mm. The mean modified Iowa hip score was 75.1. Our results indicate that Sugioka TVO is a successful procedure for hinge abduction of the hip.
Level of evidence: Level IV (case series).
