| 摘要 目的：分析半腱肌转位对髋关节旋转与伸展运动的影响。方法：采集志愿者的CT与MRI影像数据，构建髋膝关节三维有限元模型，计算并建立髋关节旋转与伸展相关肌肉的弹簧模型，依次加载相关肌肉模拟半腱肌完整、转位与缺失状态下股骨的总体应力与总体形变，以评价对髋关节内旋与伸展功能的影响。结果：成功构建CT与MRI影像数据拟合的包含骨骼、韧带与肌肉的髋膝关节三维有限元模型，计算获得各相关肌肉弹簧模型的参数。在髋关节旋转有限元模型中，半腱肌完整的情况下，髋关节旋转肌群导致的股骨整体应力为0.59057 MPa，半腱肌转位为0.90023 MPa，半腱肌缺失为0.48851 MPa；而半腱肌完整的情况下，髋关节旋转肌群导致的股骨整体形变为4.1081 mm，半腱肌转位为3.9998 mm，半腱肌缺失为3.0244 mm。在髋关节伸展有限元模型中，半腱肌完整的情况下，髋关节伸展肌群导致的股骨整体应力为2.8383 MPa，半腱肌转位为2.1019 MPa，半腱肌缺失为1.4665 MPa；而半腱肌完整的情况下，髋关节伸展肌群导致的股骨整体形变为6.6956 mm，半腱肌转位为6.314 mm，半腱肌缺失为4.6261 mm。结论：半腱肌转位较半腱肌切取更好的保持了髋关节的内旋与伸展运动功能，而半腱肌切取对髋关节运动有显著影响，可能会带来相关的运动损伤风险。 |

| ABSTRACT Objective: To analyze the effect of semitendinosus transposition on rotation and extension of hip. Methods: CT and MRI image data of volunteer were collected to construct a three-dimensional finite element model of hip and knee, and the spring model of the muscles related to hip rotation and extension was calculated and established. The relevant muscles were successively loaded to simulate the total stress and total deformation of the femur under the semitendinosus intact, transposition and missing, so as to evaluate the impact on the internal rotation and extension function of the hip. Results: The three-dimensional finite element model of hip and knee, which included bone, ligament and muscle, was successfully constructed by fitting CT and MRI image data, and the parameters of each muscle spring model were calculated. In the finite element model of hip rotation, when the semitendinosus was intact, the overall stress of femur caused by hip rotation muscle group was 0.59057 MPa, the semitendinosus transposition was 0.90023 MPa, and semitendinotomy was 0.48851 MPa. In the case of intact semitendinosus, the total femur deformation caused by hip rotators was 4.1081 mm, the semitendinosus transposition was 3.9998 mm, and semitendinotomy was 3.0244 mm. In the finite element model of hip joint extension, when the semitendinosus was intact, the overall stress of femur caused by hip joint extension muscle group was 2.8383 MPa, the semitendinosus transposition was 2.1019 MPa, and the semitendinotomy was 1.4665 MPa. In the case of intact semitendinosus, the total femur deformation caused by hip extension muscle group was 6.6956 mm, the semitendinosus transposition was 6.314 mm, and the semitendinotomy was 4.6261 mm. Conclusion: Semitendinosus transposition can better maintain the internal rotation and extension function of the hip than semitendinotomy, and semitendinotomy has a significant effect on hip movement, which may bring the associated risk of sports injury. |
