| 摘 要： | 目的：了解中空滑动母子钉板（MRP）固定股骨颈骨折的生物力学特性。材料与方法：8具新鲜成人尸体股骨标本，造成股骨颈骨折后分别以MRP、TSP及TGP固定，通过生物力学测试对三种内固定器的力学特性作比较分析。结果：股骨颈骨折以MRP固定后，抗剪切能力，轴向刚度和弯曲刚度明显优于TSP和TGP固定。结论：采用中空滑动母子钉板固定股骨颈骨折，符合生物力学原理，具有良好的推广应用价值。

| Abstract: | Objective: To investigate the biomechanical characterestics of complex cannulated sliding compression screw and side-plate in the treatment of femoral neck fracture. Materials and mechods: Femoral neck fractures of eight cadaveric femura caused by a saw were fixed by complex cannulated sliding compression screw and side-plate (MRP), TSP and TGP, respectively. Biomechanical characterestics of three different devices were compared. Results: A fracture of femoral neck with MRP fixation had a higher shear, compression and bending rigidity than TSP and TGP fixation. Conclusion: The application of MRP in the treatment of femoral neck fracture conforms to the biomechanical rationale and has broad prospects in orthopaedic clinic. |
