概括

旋转手套肌肉退化在B-glenoid骨关节炎中主要是脂肪透,而不是不对称. 不对称的骨损失与内脊髓缩和脂肪透相关,与部后部头部脱有关.

科学领域:

整形外科手术整形外科手术
生物机械工程生物机械工程
放射学放射学是一门学科.

背景情况:

旋转手套肌肉 (RCM) 退化,骨形态和部头部突起 (HHS) 是B-关节性骨关节炎中全面肩膀关节塑造失败的确立危险因素.
了解RCM不对称及其与其他风险因素的关系至关重要,但仍在调查中.

研究的目的:

在B-glenoids中描述RCM退化变异性.
为了分析RCM退化,形形态和HHS之间的共变性.

主要方法:

计算机断层扫描 (CT) 扫描量化了60个B-glenoids和25个对照组的3DRCM退化 (缩,脂肪透).
使用统计形状模型评估了3D护甲形状.
3D HHS 的量化.
相关性分析模拟了风险因素之间的共变性模式.

主要成果:

在B-glenoids中的RCM退化主要涉及脂肪透,没有显著的前后不对称.
在B-glenoids中,不对称的骨损失与增加的RCM缩和内骨脂肪透有关.
确定了四种RCM退化的显著模式和头巾形状,解释了90.3%的相关性.
主要模式将后面的状腺侵蚀和心肌旋转与增加的骨内脂肪透联系在一起,这也与后面的HHS相关.

结论:

在B-关节骨关节炎中,RCM退化主要以脂肪透为特征,而不是不对称.
特定的RCM退化模式和头骨形态与HHS有关,为植入物失败提供了洞察力.
这些发现可以增强肌肉骨模型,用于预测肩膀关节整形手术中的术后风险.

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...

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...
