Three cancellous bone screws versus a screw-angle plate in the treatment of Garden I and II fractures of the femoral neck.

A consecutive clinical series of 33 patients with either an undisplaced (Garden I) or minimally displaced (Garden II) femoral neck fracture was randomly divided into two operative protocols. Half of the fractures were treated with three cannulated cancellous bone screws, while the other half were treated with a standard screw-angle plate device. After a mean follow-up of 2 years, 4 patients had died, while 20 of the remaining 29 hips showed excellent or good, 3 fair and 6 poor functional results. The three-screw fixation seemed to yield more technical complications as compared to the screw-angle plate fixation. However, the differences in functional end-results were of no clear statistical significance. We conclude that the screw-angle plate device gives acceptable results in this group of fractures. The use of cannulated hip screws may be more advantageous in the treatment of dislocated femoral neck fractures, where the torsional strength of fracture fixation and femoral head viability are more critical.
