目的:实体测试股骨上端生物力学分布情况,了解骨质极限应力状态,为临床工作积累更多经验。
方法:选择60例新鲜中国人尸体骨股,去除表面肌肉、韧带等组织,供体年龄36～72岁,平均56.4岁,其中男性41根,女性19根,随机分为两组,分别在力学专业实验室以专业设备进行压应力和折弯应力的力学测试,搜集单位应力下各测点的受力值。
结果:股骨上端耐受压应力的能力较耐受折弯应力强,压应力主要受力区域为股骨颈基底部内外侧和小粗隆截面内侧;折弯应力主要受力区域为股骨颈基底后侧以及小粗隆截面后侧。主要受力区域有较强的骨质强度,目前主流的粗隆骨折内固定物和人工股骨柄均以此为生物力学基础设计。
结论:本研究结果显示的数据未查到既往文献报道,可以为内固定物和股骨柄改进提供资料。临床上需要针对试验结果选择合适的骨折内固定和人工股骨柄,更完善的数据结果需要远期深入的研究。 |

Abstract:
Objective: To study the bone state with ultimate stress by examining biomechanical distribution of upper femur in Chinese,in order to accumulate more experiences for clinical work.
Methods: Totally 60 Chinese femurs from fresh cadavers were randomly divided into two groups. All the femurs were cleaned,and the body age ranged from 36 to 72 years old,averaged 56.4 years,including 41 from males,and 19 from females. These two groups underwent mechanical stress and bending stress tests. Special mechanical laboratory and machines were used to get the information. Results about the loading value at each testing point under stress were collected.
Results: The four faces of the upper femur suffered different stress under external forces. The bone on upper femur can tolerate more mechanical stress than bending stress. Medial and lateral region of the femur neck and the rear side of the small tuberosity section were themain position enduring the vertical stress. The rear position of the base femur neck and the small tuberosity section were the main regions enduring the bending stress. Those main positions had strong cancellous bones. The intertrochanteric fracture fixation and artificial femoral stems were designed depending on this biomechanical basis.
Conclusion: According to our experiment result,doctors need to chose more effective fixations for upper femur fracture,and femoral stems for the patients. More information should be collected by further researches. |
