[Trochanteric pseudoarthroses after total hip arthroplasty: their fixation with a new claw-plate].
In the authors experience, non-union of the greater trochanter after its division occurred in 3p. 100 of cases. The treatment is difficult when non-union is well established. The authors have devised an original type of plate whose upper part is made of a double hook to grip the greater trochanter. The lower part of the plate is screwed to the femoral shaft. The use of this plate is combined with horizontal wiring to counteract the action of gluteus medius. Bone grafting is sometimes needed in addition. Nineteen cases were treated in this way, all with success.
