概括

肖特尔点和表面的中间附带带重建提供了优越的带稳定性,而不是添加器大肌固定. 这些技术可以减少侧向位移在中间骨关节带重建为骨不稳定性.

科学领域:

整形外科手术整形外科手术
生物力学生物力学
运动医学运动医学

背景情况:

没有植入的中侧骨带重建是骨不稳定的常见治疗方法.
有限的生物力学数据存在,比较腿部附着部位:肖特尔点,表面中间侧带 (sMCL) 和添加体大肌 (AM).
还评估了一种新的三角形重建 (sMCL + AM).

研究的目的:

为了生物力学地比较不同股骨附着点的疗效,用于无植入体的中间骨带带重建.
在重建后使用肖特尔点,sMCL,AM和联合三角技术来评估骨稳定性.

主要方法:

通过使用肌肉激活模拟器测试了8个尸体膝盖,复制浅膝盖 flexion.
在横向负荷下测量了带侧面位移和旋转,在切断了中间带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带带
数据使用重复测量ANOVA在20°,30°,45°和60°曲时进行分析.

主要成果:

所有的重建都显著减少了与切断状态相比的侧面带位移.
肖特尔点和sMCL重建显示侧向位移明显小于AM重建 (p <0.05).
所有的技术都显示出与完整状态相比,中侧骨约束增加的趋势.

结论:

肖特尔点和sMCL固定提供优越的生物力学稳定性,用于中部骨肌重建与添加器大肌固定相比.
存在过度约束的可能性,这可能会增加二次骨关节炎的风险.
需要进一步的临床研究来将生物力学发现与患者的结果相关联.

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
