Muscles of the Shoulder01:23

Muscles of the Shoulder

3.5K
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.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Muscles that Move the Arm01:31

Muscles that Move the Arm

1.5K
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...

科学领域:

  • 整形外科手术 整形外科手术
  • 运动医学 运动医学
  • 肩膀重建的重建 肩膀重建的重建

背景情况:

  • 上部乳房前后部 (SLAP) 损伤是常见的肩部损伤.
  • 修改的双排 biceps 延展 (MDBT) 是SLAP损伤的有效治疗方法.
  • 在MDBT的结果中,同时进行滑轮环修复的作用需要进一步调查.

研究的目的:

  • 评估MDBT期间轮环修复对肩部功能和稳定性的长期影响.
  • 为了在II型SLAP病变患者中比较MDBT与无滑轮环修复之间的结果.

主要方法:

  • 对157名单独单边II型SLAP病变患者进行了回顾性研究,这些患者接受了MDBT治疗.
  • 患者被分为两组:没有轮环修复 (n=77) 和轮环修复 (n=80).
  • 统计分析 (t-test,Anova,chi-square) 和拉索回归被用来识别显著变量并构建一个预测模型.

主要成果:

  • 两组在1年后观察到ASES和UCLA分数的显著差异 (p < 0.01).
  • 通过拉索回归确定的主要风险因素包括分组,骨矿物密度T值和手术后3个月UCLA得分.
  • 使用这些显著变量开发了一个预测模型.

结论:

  • 经过修改的双排 biceps 延伸与滑轮环修复,与传统的 MDBT 相比,显示出优越的长期腺关节功能.
  • 这种技术有助于更好地恢复关节的生物状态.
  • 轮环修复是MDBT的一个有价值的补充,用于优化SLAP病变治疗的结果.
