概括

较小的三叉 (LT) 形状是近距离股骨旋转的不可靠标记,特别是在外部旋转期间. 在大腿骨折固定过程中仅依靠LT形状,可能导致不准确的旋转对齐.

科学领域:

整形外科手术整形外科手术
生物机械分析分析
医学成像医学成像

背景情况:

较小的三叉体 (LT) 形状通常用于评估手术期间的近端股骨旋转.
之前关于其可靠性的研究已经产生了相互矛盾的结果.

研究的目的:

为了评估较小的三叉体 (LT) 形状作为近距离股骨旋转标志物的可靠性.
为了确定在一系列的旋转位置中LT配置的准确性.

主要方法:

利用SOMA数据库分析了1722张整个大腿骨的CT扫描.
为每个大腿骨构建的LT配置文件通过一个80°的旋转弧以2.5°的增量.
与精确的股骨旋转相关的56,826 LT 轮测量结果.

主要成果:

LT 概况与近端股骨旋转有较弱的相关性 (R2 = 0.32).
外部旋转的35°弧只导致LT轮的变化为1mm.
女性表现出比男性 (19.2°) 更多的股骨前转 (23.9°);平均而言,男性的LT更突出.

结论:

距离线形状是一个不太可靠的指标,比以前假设的近端股骨旋转,特别是与外部旋转.
在骨骨折固定过程中使用LT档案进行旋转评估时建议谨慎使用.
建议通过临床检查或其他标记来确认旋转,以避免不对齐.

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...
