Abstract
In a series of 45 subtrochanteric fractures treated with a sliding screw-plate device, union was achieved in 43 patients (95.3%). Most were Seinsheimer Type II C (9), Type IIIA (12), and Type V (18). Fractures were stabilized in a valgus position (average, 140.degree.), with prlimary medial displacement of the femoral shaft (25 patients). Radiographic analysis of the degree of postoperative impaction of the fragments correlated with the fracture pattern. Fractures with medial cortical comminution such as Type IIIA and Type V were the most unstable, with an average of 10.8 and 8.0 mm axial impaction, respectively, and were at the greatest risk of complication. The sliding screw-plate device is a reliable method of achieving union in subtrochanteric fractures.
