概括

四头肌肌的厚度从远距离到近距离显著下降. 这种解剖学变异对于优化前十字带 (ACL) 重建手术中的移植准备至关重要.

科学领域:

整形外科手术整形外科手术
人体解剖学解剖学解剖学
生物医学工程生物医学工程

背景情况:

前十字带 (ACL) 重建通常使用从四头肌 (QT) 收获的移植物.
了解QT的形态是成功采购和准备移植的必要条件.
QT厚度的变化会影响移植直径和手术结果.

研究的目的:

为了评估四头肌肌 (QT) 厚度在尸体样本中的变化.
提供数据,可以改善QT收获技术和ACL重建的移植准备.

主要方法:

八个新鲜冷的尸体腿被解剖,暴露了QT.
肌厚度是用刀在两个点测量:骨的上极 (远距离) 和65毫米近接插入.
进行了单变量分析,以确定平均厚度,标准偏差和置信区间.

主要成果:

平均QT厚度是8.7毫米在远端形插入部位和6.5毫米在65毫米近端插入部位.
在两个测量点之间观察到2.2毫米的显著平均差异 (P < .001).
靠近的QT距离平均比远端肌薄25.3%,在样本之间存在相当大的差异.

结论:

四头肌表现出从远距离到近距离的厚度显著且持续下降.
不均的厚度和个体肌之间高度的变化是关键因素.
在QT厚度的解剖学变化需要在ACL重建的移植准备过程中仔细考虑,以确保适当的道定位和移植大小.

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 neck...
