1. Rotational osteotomy and internal fixation would seem to have a definite place in the treatment of non-union of intracapsular fractures of the neck of the femur, delayed union or non-union of trochanteric fractures, and non-union of subtrochanteric fractures. It would seem to be the treatment of choice for congenital coxa vara and for fractures of the neck of the femur in children. It may eventually be shown to have usefulness in hips having old deformed changes of coxa plana, in certain instances of aseptic necrosis, or in old severe slipping of the femoral epiphysis.
2. If rotational osteotomy is to be done, it should be performed so as to elevate the head of the femur as nearly in complete alignment with the shaft as possible (90 degrees).
3. The procedure is extensive, and difficulty may be encountered in securing abduction without displacement of fragments due to tension of soft tissues.
