概括
全关节整形术 (THA) 后的患者表现出部延伸和运动范围的减少. 这与骨盆和大腿协调的改变有关,THA患者在走路时表现出更多的相位运动模式.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 步态分析 步态分析
背景情况:
- 接受全关节整形术 (THA) 的患者与健康人群相比,往往表现出改变的关节运动.
- 具体来说,THA后通常会观察到部延伸和运动范围的减少.
研究的目的:
- 为了调查THA患者和健康对照人群在行走时平面部,骨盆和大腿动力学的差异.
- 探索这些群体之间的骨盆大腿运动协调和协调变异性的变化.
主要方法:
- 利用3D运动捕捉系统记录部,骨盆和大腿的斜腰平面动力学,10名THA患者和10名对照患者在走路时.
- 采用修改的矢量编码技术来量化骨盆大腿协调和协调变化模式.
- 与THA和对照组之间的峰值动力学测量和协调模式进行了比较.
主要成果:
- 治疗THA后的患者表现出明显较小的峰值部延伸和运动范围 (p ≤ .036).
- 在THA患者 (p ≤ .036) 中观察到明显减少前部倾斜和运动范围的峰值.
- THA患者显著表现出更多的阶段内和较少的反阶段骨盆-大腿运动协调模式 (p ≤ .037).
结论:
- 在THA患者中,部延伸和运动范围的减少归因于大腿前部倾斜的减少,限制了大腿运动范围.
- 改变的骨盆-大腿协调,以增加相位运动为特征,可能会导致骨盆和大腿作为单一单位运作,导致THA后的斜腰平面运动减少.

Muscles that Move the Thigh
1.2K
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Bones of the Lower Limb: Femur and Patella
2.6K
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...
