概括

在V形切除术 (VT) 和标准切除术 (ST) 修复技术显示,在解剖学全肩关节整形术 (aTSA) 后,类似的生物力学强度. 在前三个循环中,VT在减少爬行方面提供了轻微的初始优势.

背景情况:

下肌肉的完整性对于解剖学全肩关节整形术 (aTSA) 后的结果至关重要.
一种新的V形断面术 (VT) 技术已被开发出来,作为标准断面术 (ST) 的替代方案.
对VT与ST修复的生物机械比较对于评估其潜在益处至关重要.

研究的目的:

在生物力学上比较V形切割术 (VT) 与标准切割术 (ST) 的修复完整性.
评估VT和ST修复之间的周期性位移,爬行,刚性和负载到故障的差异.

主要方法:

一项生物机械研究利用6对新鲜冷的尸体肩部样本.
下骨关节切除 (VT或ST) 随后是部头关节整形术和使用8个的修复.
循环负荷 (2-100 N,45°绑架,1 Hz,3000 个周期) 来测量位移,爬行,刚性和负载到故障.

主要成果:

在3000个循环中,VT和ST修复之间没有循环位移或度的显著差异.
与标准断层切除 (ST) 相比,V形断层切除 (VT) 在最初的3个周期中显示出明显较低的爬行.
负载到故障在VT和ST修复之间没有统计学上的差异.

结论:

在维修时,V形断 (VT) 和标准断 (ST) 呈现同等的生物力学特性 (刚性,位移,负载到故障).
VT显示在减少爬行方面具有潜在的早期优势,这需要进一步调查.
这种V形切割术技术需要额外的临床评估,以确定其在aTSA中比标准切割术具有的功能益处.

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...

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