概括

肩膀尺寸预测了逆肩关节整形术 (RSA) 螺丝放置的最高安全区域. 较短的头骨脊柱增加后皮层损伤的风险,这表明形态测量可以指导RSA规划.

科学领域:

整形外科手术整形外科手术
人体解剖学解剖学解剖学
生物机械工程生物机械工程

背景情况:

反向肩关节整形 (RSA) 需要安全固定状骨基板.
在RSA期间插入外围螺丝可能会损伤上神经 (SSN).
现有的螺丝安置安全区可能无法考虑个体的头皮骨解剖学.

研究的目的:

为了确定RSA螺杆放置所描述的安全区是否与头巾形态学相关.
评估RSA期间常见的螺丝位置是否会产生差异性的SSN风险.
为了研究头尺寸和SSN在螺丝插入时的接近之间的关系.

主要方法:

剖析20个尸体肩膀,以测量安全区域和头巾尺寸.
模拟的RSA基板固定与不同的上部和后部螺丝位置.
分析皮质突破和SSN的接近性,将发现与 scapular morphometry 相对应.

主要成果:

高级安全区与头巾尺寸有显著的相关性 (r = 0.78-0.86).
所有上螺丝仍然是骨内螺丝;对于后螺丝,没有显著的SSN近距离差异.
后皮层损伤发生在50%的病例中,与较短的头骨脊柱长度相关 (p = 0.027).

结论:

头尺寸预测了高级安全区,表明了解剖学上的可扩展性.
后部安全区并不是由头巾尺寸预测的,但较短的脊柱增加了突破风险.
骨形状学可以为手术前的RSA规划提供信息,但需要前性验证.

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...
