概括
前臂旋转显著影响远距离放射关节 (DRUJ) 压力,特别是在俯卧. 由于DRUJ压力升高,应避免在早期TFCC伤害康复中进行俯卧练习.
科学领域:
- 骨科生物力学 骨科生物力学
- 上肢解剖学 上肢解剖学
- 运动医学研究 运动医学研究
背景情况:
- 遥远的放射性关节 (DRUJ) 对于前臂旋转至关重要.
- 了解DRUJ的关节内压力对于诊断和治疗损伤至关重要.
- 前臂肌肉负荷和稳定结构影响DRUJ机械.
研究的目的:
- 为了研究前臂肌肉负荷和稳定器中断对DRUJ关节内压力的影响.
- 分析各种前臂旋转的压力变化 (中性,发音,俯卧,延伸,曲).
- 评估三角纤维软骨复合体 (TFCC) 和其他稳定剂损伤对DRUJ压力的影响.
主要方法:
- 使用十个尸体前臂模型,没有显著的DRUJ病理.
- 在六个负载条件下,在DRUJ中测量了关节内压力,包括没有负载,负载和不同程度的稳定器破坏 (TFCC,关节带,骨间膜,四角前).
- 在五个不同的前臂旋转中评估压力.
主要成果:
- 在没有中断,负载和中断的TFCC条件下,在置中始终观察到最高的关节内压力.
- 在没有中断的负载条件下,与没有负载相比,在中性旋转中,DRUJ压力增加了1.57 kg/cm2.
- 经过TFCC中断的曲显示出明显的压力增加 (4.3 kg/cm2),而仅经过TFCC中断的曲也增加了压力 (3.3 kg/cm2).
结论:
- 前臂关节内压力受到旋转和稳定结构的完整性显著的影响.
- 假设位置会产生更高的DRUJ压力,特别是当TFCC受到损害时.
- 对于TFCC受伤的康复方案应谨慎地在初始阶段进行俯卧练习,以减轻过度的DRUJ压力.

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 of the...
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.
