概括

部引和引显著改变边缘性部张症 (BHD) 患者的股骨上垂骨顶 (FEAR) 指数. 诱导会增加FEAR指数值,而诱导会降低它们,从而影响X射线评估.

科学领域:

整形外科手术整形外科手术
放射学放射学是一门学科.
生物机械分析分析

背景情况:

边缘性关节发育不良 (BHD) 呈现出诊断方面的挑战.
对关节形态的准确评估对于治疗计划至关重要.
股骨上腺骨顶 (FEAR) 指数是一种用于评估部发育不良的放射测量仪.

研究的目的:

为了确定带和带对FEAR指数的影响.
为了分析这些效应,使用常规的前后盆腔放射图.
为解释BHD患者的FEAR指数测量提供见解.

主要方法:

在BHD (18° ≤ LCEA <25°) 的患者中,对89个部进行了回顾性分析.
从骨盆放射图测量初始部增/减动和FEAR指数.
使用外科手术计划软件模拟不同的带 (高达20°) 和带 (高达30°).
皮尔森相关性来评估部位置和FEAR指数之间的关系.

主要成果:

最初的X光照显示,无意中平均引值为-5.3°±3.1°.
最初的附加/绑架时的平均FEAR指数 (-3.6° ± 7.2°) 与中性位置 (-9.2° ± 7.0°) 有显著差异.
在关节绑架/绑架和FEAR指数之间发现了强烈的负相关性 (r=1,P<.001),绑架降低了FEAR指数值.

结论:

带和带显著影响盆腔X光片上的FEAR指数测量.
观察到一个线性关系:添加或提取的5°变化导致FEAR指数的5°变化.
这些发现强调了在解释BHD的FEAR指数时考虑部定位的重要性.

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...
