The treatment of developmental coxa vara by abduction subtrochanteric and intertrochanteric femoral osteotomy with special reference to the role of adductor tenotomy.

Regardless of the method of fixation, results were good in 84.5 per cent of abduction trochanter osteotomies for developmental coxa vara in 32 hips. Operative treatment is recommended after 18 years of age. Inadequate correction occurred only in children in whom an adductor tenotomy had been omitted. Unsatisfactory correction was caused more frequently by faulty surgical technique than by bony remodelling. The latter was not seen after the age of 6 years.
