Each of the femoral neck fracture of 9 fresh cadaver femora samples was fixed with 3 hollow doublehead compression screws. Biomechanical experiment showed that hollow double head compressionscrew is a more effective internal fixation devise in the treatment of femoral neck fracture. The 3hollow double head compression screw method appeaed to have distinct advantages over themethods by using 3 solid screws or trifin screws in anti-pressure, anti-bending, torsional strengthand torsional rigidity. Statistical analysis showed signigicant difference(p<0.01). Hollow doublehead compression screw method has been performed on 22 patients, and proved to be able to speedup bone formation and recovery of hip or knee joint function after operation. At present, it isdlemed a relatively ideal fixation method in the treatment for fracture of femoral neck. It deserveswides application and more more popularization.
