概括

膝关节骨关节炎的开高骨切除术 (HTO) 改善了下肢肌肉的激活和协调. 这种手术减少了肌肉的共同收缩,并在手术后的一年内增强了肌肉功能.

科学领域:

整形外科整形外科整形外科
生物力学生物力学
运动学运动学

背景情况:

中间膝关节关节炎 (KOA) 显著影响下肢功能.
开式高骨切除术 (HTO) 旨在纠正对齐并缓解KOA症状.

研究的目的:

为了研究HTO后体重轴承线变化对KOA患者下肢肌肉激活的影响.
分析肌肉共同收缩,电肌图 (EMG) 信号,以及HTO后步行过程中的激活时间.

主要方法:

一项涉及21名接受HTO的KOA患者的队列研究.
在手术前和手术后6个月和12个月,进行三维步态分析和表面肌电图.
在立场阶段评估七个下肢肌肉的合收缩指数,集成EMG和根平均平方.

主要成果:

在手术前的高并发收缩指数 (大中 - 双腿骨,大中 - 胃骨) 在HTO后显著下降.
6个月后,在大多数下肢肌肉中观察到集成EMG和根平均平方值的增加.
在12个月后,在 gluteus medius 和 vastus medialis 中发现了改善的激活,增加的EMG,以及更早的时间.

结论:

在KOA患者中,HTO有效降低异常肌肉合收缩.
该程序增强了下肢肌肉的整体激活,并在一年内改善了肌肉协调.
在HTO之后,Vastus medialis表现出更好的激活模式,有助于改善膝盖功能.

Bones of the Lower Limb: Tibia and Fibula

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Muscles of the Leg that Move the Foot and Toes

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

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...
