- 整形外科手术 整形外科手术
- 生物机械工程 生物机械工程
- 创伤研究研究创伤研究
背景情况:
- 无头压缩螺丝 (HCS) 广泛用于小骨头和关节骨折的固定.
- 对于放射性头部骨折中的HCS应用,生物力学数据有限.
研究的目的:
- 为了比较单个斜HCS结构与标准锁定辐射头板 (LRHP) 和用于辐射头骨断裂固定的双皮质螺丝 (DCS) 结构的单个斜HCS结构的生物力学特性.
主要方法:
- 在使用HCS,LRHP和DCS构造的辐射协同骨模型上进行了生物力学测试.
- 样本经历了循环加载,然后进行负载到故障测试.
主要成果:

01:27Fractures: Bone Repair
3.3K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

01:09Bones of the Upper Limb: Radius
2.2K
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...
