概括
芝麻骨相对于大指甲手关节 (MCP) 关节的位置在背部脱时发生显著变化. 芝麻状物定位可以帮助诊断指MCP关节脱,并确认成功减少.
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.
- 人体解剖学 解剖学 解剖学
背景情况:
- 大指元手腕关节 (MCP) 关节容易发生背部脱.
- 芝麻骨的位置可能表明MCP关节的状态,但其诊断实用性尚不清楚.
研究的目的:
- 为了研究芝麻骨和指MCP关节在正常和脱状态之间的位置关系.
- 确定芝麻状物定位是否可以帮助诊断背指MCP关节脱.
主要方法:
- 从门诊患者和急诊患者获得的60张同度和56张异度手部X射线的分析.
- 测量芝麻骨长度 (DP) 和距离MCP关节 (DJ) 的距离,计算比率 (R).
- 使用独立样本和配对样本t测试进行统计分析.
主要成果:
- 在正常关节的DJ和R中观察到显著的性别差异 (p < 0.01).
- 在脱关节减少前 (-0.47) 和减少后 (0.58) 的比率R显著不同 (p < 0.01).
- 芝麻骨的远端在脱位时超出MCP关节,在缩小后在MCP关节以下.
结论:
- 芝麻骨的相对位置存在显著差异,大指MCP关节脱而不是缩小.
- 芝麻骨在指MCP关节之外的位置表明背部脱.
- 在指MCP关节下方的芝麻骨位置表明成功的关节缩小.

01:10Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

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.
