概括
在缩小和关联骨和骨 (RASL) 程序中添加一个骨头 (SC) 螺丝增强了手腕的稳定性. 这种技术在模拟紧握拳头负荷时减少了脚 (SL) 关节扩张,改善了手腕的生物力学.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 手术手术手术手术手术
背景情况:
- 缩小和关联骨和月球 (RASL) 程序的目的是稳定骨.
- 评估了使用临时脚 (SC) 螺丝增强RASL的有效性,以提高脚 (SL) 关节的稳定性.
- 主要结局是SL关节扩张在模拟的紧握拳头下.
研究的目的:
- 评估RASL手术中添加SC螺丝是否可以改善手腕和SL关节的稳定性.
- 为了比较RASL带有和没有SC螺丝增强的生物力学效应.
主要方法:
- 在循环轴向力下测试了12个尸体手腕,模拟紧握拳头的负载.
- 在完整的手腕,SLIL切割的手腕和手术治疗的手腕中测量了SL关节运动.
- 静态和循环运动扩散被量化为RASL和RASL与SC螺丝 (RASCL) 程序.
主要成果:
- 与单独使用RASL相比,RASCL手术导致了更多的脊椎骨和月球骨的解剖缩小.
- 与RASL相比,RASCL表现出明显较少的循环运动扩散,紧密模仿完整的手腕.
- 仅RASL就显示了类似于SLIL受伤模型的循环运动.
结论:
- 使用SC螺丝的增强在模拟紧握拳负荷下降SL关节扩张.
- 缩小和协会的骨,头骨和月球 (RASCL) 构造是生物力学上优越的治愈二级手腕稳定器.
- 在承重后RASCL程序之前,SC螺丝拆除是必要的.

Bones of the Upper Limb: Ulna
4.1K
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
4.4K
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.

Bones of the Upper Limb: Humerus
6.8K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
