Hook-pin and compression screw in the treatment of femoral neck fractures. Clinical trial and biomechanical study.
One hundred and two patients with femoral neck fracture underwent combined hook-pin and compression screw fixation. Eighty-five patients were followed up for over 6 months. The fracture was united in 80 patients. The advantages of this method included less trauma, simple technique and firm internal fixation and early postoperative partial weight-bearing. Biomechanical study showed that this method is superior to Smith-Petersen nailing and two hook-pins methods. The sliding and continuous compression of this method promotes impaction and healing of the fracture.
