概括
这项研究发现,与没有眼的患者相比,旋转手套撕裂 (RCT) 的患者的关键肩膀角度 (CSA) 和缩指数 (AI) 测量显著更高. 这些放射性标记可能有助于诊断有症状的RCT.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是指放射学
- 运动医学 运动医学
背景情况:
- 旋转手套撕裂 (RCT) 是全球肩部疼痛的常见原因.
- 之前的研究表明,临界肩膀角度 (CSA) 和指数 (AI) 与RCT之间存在联系.
- 研究结果的变化需要对这些放射性标志物进行进一步的调查.
研究的目的:
- 为了调查CSA和AI的放射测量和症状旋转手套撕裂的存在之间的关系.
- 为了将这些测量结果与已确认RCT的患者和使用正常旋转手套的对照组进行比较.
主要方法:
- 医疗记录,X光照和MRI的回顾性分析.
- 包括160名经过手术修复的有症状的RCT患者和106名匹配的对照.
- 使用X射线和MRI测量CSA和AI.
主要成果:
- 与对照组相比,在RCT组中观察到CSA平均值显著更高,无论成像方式 (X射线和MRI).
- 有相当比例的RCT患者表现出CSA大于35° (87.5%通过X射线,65.6%通过MRI).
- 随机试验组也显示了X射线测量的显著更高的平均AI (0.80对0.64).
结论:
- 具有症状的旋转手套撕裂与CSA和AI显著增加有关.
- 这些通过X射线或MRI测量的放射性参数可以在RCT的诊断中成为有价值的指标.

Muscles of the Shoulder
11.4K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Muscles that Move the Arm
5.8K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
