概括

平均小腿结核 (TT) 扭转角为24.7°,较高的角度与增加的骨高度有关. 没有发现TT扭曲和TT-TG距离之间的关系在没有骨骨不稳定的患者中.

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:

肋骨骨不稳定是一种常见的骨科疾病.
结核 (TT) 扭动是一个关键的解剖学参数,影响骨跟踪.
了解TT扭曲与其他形态特征的关系对于诊断和管理骨关节疾病至关重要.

研究的目的:

使用计算机断层扫描 (CT) 扫描来确定在没有已知的骨骨不稳定的个体中平均结节 (TT) 扭转角度.
调查TT扭转角度的潜在人口差异.
探索TT扭曲,结节-喉沟 (TT-TG) 距离和骨高度 (Insall-Salvati指数) 之间的关联.

主要方法:

在Stryker整形外科建模和分析 (SOMA) 数据库中对499名患者的886个膝盖进行了回顾性分析.
使用CT扫描来测量TT扭转角度,TT-TG距离和Insall-Salvati (IS) 指数.
基于性别,TT-TG距离 (≥20毫米与<20毫米) 和IS指数 (≥1.3与<1.3) 进行了统计比较.

主要成果:

平均TT扭矩角度为24.7° ± 5.2°.
与男性相比,女性的平均IS指数,TT-TG距离和TT扭矩角度显著更高.
与IS指数<1.3 (24.0°) 的患者相比,IS指数≥1.3 (26.6°) 的患者观察到显著更大的TT扭转角度.
在TT-TG距离≥20mm和<20mm的组之间,没有发现平均TT扭转角度的显著差异.

结论:

在没有骨骨不稳定的患者中,TT扭转角度的平均值为24.7°.
增加的TT扭转角与增加的骨高度 (更高的IS指数) 有关.
没有发现TT扭曲和TT-TG距离之间的相关性,这表明有不同的生物力学影响.

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...
