Artificial Hip Prosthesis in Acute and Nonunion Fractures of the Femoral Neck

The replacement value of the artificial hip prosthesis in acute and nonunion fractures of the femoral neck has been substantiated. The goal of all reconstruction procedures is attainable with correct prosthesis insertion. The relatively guarded prognosis in the acute fracture is circumvented by the immediate use of prosthesis in a selected group of cases. This report will present the criteria evolved for correct prosthesis choice, the major complications of prosthesis use, the indications for prosthesis use, and incomplete follow-up results on 70 cases. The series consisted of 49 acute and 21 nonunion fractures. CHOICE OF CORRECT PROSTHESIS A satisfactory prosthesis must be capable of restoring neck length, anatomic valgus angle, and anteversion angle. It must be capable of retaining its position in the bone. It must not cause reactive changes of absorption in the bone. Four types of prostheses were used in this series.
