概括

腿长度差异 (LLD) 低于1厘米,没有显著的步态影响. 然而,1厘米或更高的LLD会导致临床相关的步态不对称,特别是盆腔倾斜,这表明非手术干预.

科学领域:

整形医学
生物力学
儿童步态分析

背景情况:

腿长度差异 (LLD) 是一种常见的骨科疾病,其临床意义仍有争议.
轻度LLD (< 2厘米) 对儿童步态不对称的影响尚不清楚.

研究的目的:

评估儿童和青少年轻度LLD (< 2厘米) 与步态不对称之间的关系.
将这些不对称性与典型发育儿童的不对称性进行比较.

主要方法:

使用3D运动分析对475名患者 (13.1±2. 3年) 的步态数据进行了回顾性分析.
分类为四个LLD组 (1-20毫米) 和统计分析 (SPM ANOVA,回归,单向ANOVA).
对正常不对称度进行评估的临床相关性范围为40 TDC.

主要成果:

增加的LLD与更大的骨盆斜率,部引/旋转以及下肢动力学变化相关.
与TDC相比,临床相关的步态不对称性在LLD≥1cm时出现.
动力不对称差异可以忽略不计.

结论:

轻度LLD (< 1厘米) 在儿童和青少年中没有显著影响步态.
导致临床相关的步态不对称,特别是骨盆斜度.
对于LLD≥1厘米的非手术干预措施,如鞋子提升,以减轻步态变化.

Muscles that Move the Leg

Muscles that Move the Leg

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

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....
