Twenty hips (12 patients) with congenital coxa vara, treated with valgus subtrochanteric osteotomy, were reviewed retrospectively. The average Hilgenreiner-epiphyseal (HE) and head-shaft (HS) angles at the initial evaluation were 66[degrees] and 96[degrees], respectively. The average postoperative follow-up time was 20 years. Five of the 12 hips with trochanteric overgrowth had abductor weakness. A postoperative HE angle of 35[degrees] or less and a HS angle of 130[degrees] or more was correlated with consistently satisfactory results.
