概括

骨过程 (CP) 尖端的位置,特别是它的侧面,后部和下部位置,与骨下部 (Ssc) 撕裂有很大关系. 这些发现突出了用于识别Ssc撕裂风险的新成像指标.

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:

骨过程 (CP) 和它与骨的关系在肩膀生物力学中至关重要.
下 (Ssc) 撕裂是常见的肩膀损伤,其病因尚未完全理解.
了解CP的形态变异可能为Ssc撕裂的发展提供见解.

研究的目的:

为了研究心肌流程 (CP) 尖端与状腺相对的位置关系,在患有 subscapularis (Ssc) 撕裂的患者中.
为了测试 CP 尖端在 Ssc 撕裂的个体中更低劣,侧面和后部的假设.
引入和验证用于评估CP位置的新型成像角度.

主要方法:

一项病例对照研究涉及34名患有孤立Ssc撕裂的患者和44名对照.
介绍在MRI上测量的轴心中央状腺心脏角 (acGCA) 和斜面中央状腺心脏角 (scGCA).
在两组中评估了acGCA,scGCA,关键肩膀角度 (CSA) 和状腺倾斜度 (GI).

主要成果:

与对照组相比,在Ssc撕裂组观察到明显更高的acGCA值 (p<0.001),截止值为28.3°,表明Ssc撕裂的高灵敏度 (93.3%) 和特异性 (93.1%).
在Ssc撕裂组 (p<0.001) 中发现了显著更高的scGCA值,切线为41.8°,显示了80%的灵敏度和89.7%的特异性.
在Ssc眼组也表现出明显更高的CSA和GI值 (p<0.001和p<0.012,分别).

结论:

升高的acGCA值 (大于28.3°) 表明CP尖端位置较为侧向和后向,与Ssc撕裂有关.
升高的scGCA值 (大于41.8°) 表明CP尖端位置较低,也与Ssc撕裂有关.
这些新型指数 (acGCA和scGCA) 表明,侧面,后部和下部位置的心肌尖与 subscapularis 撕裂有关.

Muscles of the Shoulder

Muscles of the Shoulder

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.

The anterior thoracic muscles include the serratus anterior, subclavius, and...

Muscles that Move the Arm

Muscles that Move the Arm

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...
