Cuneiform osteotomy of the femoral neck in the treatment of slipped capital femoral epiphysis.

I reviewed the cases of eighty-two patients (106 hips) with slipped capital femoral epiphysis who were treated during a twenty-four-year period. Of these, forty-two hips had a sufficiently severe displacement to require surgical correction by means of a cuneiform osteotomy of the neck of the femur just distal to the physis. The purpose was to restore the normal anatomical relationship of the proximal capital femoral epiphysis to the neck of the femur. Follow-up of these patients ranged from two to twenty-two years, with an average of nine years and nine months. Aseptic necrosis developed in one femoral head and osteoarthritis developed in one hip. The remaining forty hips were graded as having an excellent result.
