[Pseudarthrosis of the femur neck and ununited ipsilateral diaphyseal fracture. Value of an adjustable 2-piece nail plate].

The authors have treated four patients presenting in the same limb a pseudarthrosis of the neck of the femur and an ununited fracture of the femoral shaft. All the cases were treated by fixation of the diaphyseal lesion and valgus osteotomy of the femoral neck. To achieve this, the authors recommend the use of a two-piece nail plate sufficiently long to bridge the lower fracture site. In all the cases, union occurred without necrosis of the femoral head.
