概括

整部关节整形手术患者在手术前后都会出现步态障碍. 虽然内部部旋转改善了手术后的情况,但外部旋转的时刻保持不变,可能是由于手术方法对肌肉产生影响.

科学领域:

整形外科手术整形外科手术
生物力学生物力学
步态分析步态分析

背景情况:

关节骨关节炎显著影响步态,与健康成年人不同,关节旋转会影响步态和重心.
在全关节整形术 (THA) 后,水平平面的步态变化没有得到充分的证据.
这项研究调查了THA患者的手术前和早期术后步态特征.

研究的目的:

为了澄清关节整形手术前后的步态特征.
分析关节运动,肌肉力量和步态参数的变化.

主要方法:

分析了一组由12名女性患者组成的队列,这些患者通过后侧治疗方法接受了初级THA治疗.
用三维运动分析进行了手术前和手术后的步态测量.
进行比较的关键参数包括运动范围,肌肉力量,步行速度,步伐长度,重心运动,干角度,部角度和关节时刻.

主要成果:

术后发现显示,与健康个体相比,手术侧的下部最大部绑架时刻和干屈曲角度较低.
在姿势阶段,术后观察到部内部旋转的显著增加.
在手术后,重心在横向方向的偏移的距离显著减少.

结论:

走路障碍在手术前存在,并在THA后持续存在.
虽然THA后的内向部旋转接近正常步态,但外部旋转时刻没有变化.
后侧外科手术方法可能会影响部外部旋转肌肉,导致持续的步态障碍.

Anatomical Movements

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
