概括

标准化的valgus应激放射能可以识别中间肘部软组织损伤. 这种方法为MRI提供了一种经济有效的替代方案,用于诊断肘部不稳定性,特别是在60°曲时.

科学领域:

整形外科手术整形外科手术
诊断成像诊断成像诊断成像
生物力学生物力学

背景情况:

目前对肘部位不稳定的诊断依赖于昂贵的MRI或MRA.
压力放射已经显示出作为替代诊断工具的希望.
这项研究旨在评估中部肘部软组织病变的标准化valgus应激放射.

研究的目的:

为了评估标准化的valgus应力放射学在识别中间肘部软组织病变的有效性.
为了比较在完整和受伤的肘部状态下在压力下关节的缺口.
确定最佳的成像位置,以检测中间肘部的不稳定性.

主要方法:

六个尸体的肘部经历了使用Telos设备的压力放射,压力为50N valgus.
在完整的状态下测量了腰关节空间,MCL截面和普通曲肌截面状态.
图像检测是在0°,30°和60°的曲位置进行的,前臂处于中性,俯卧和俯卧的位置.

主要成果:

与完整状态相比,在带和/或肌缺乏状态下,平均关节缺口显著增加.
在大多数位置 (p<0.05) 中,常见的曲肌切断导致了统计学上显著的腰关节间隙.
中间关节松度在60度曲和位/中性旋转时最大.

结论:

远距离应激放射能在检测中部肘部重要的带损伤方面是有效的.
动态关节稳定可能会影响MCL损伤的检测.
肘部应力放射应该包括在60°曲处进行检查,以获得最佳评估.

Bones of the Upper Limb: Ulna

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Radius

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...
