概括

这项研究详细介绍了关键手腕关节的神经供应, 了解这些精确的神经解剖学模式可以改善手和手腕关节炎的外科治疗结果.

科学领域:

骨科手术
神经解剖学
治疗疼痛

背景情况:

关节神经损伤可以治疗慢性手和手腕疼痛.
优化结果需要详细了解关节内置模式.

研究的目的:

精确地绘制第一个手指甲骨关节 (CMC),放射性手指骨关节 (RCJ),三角纤维软骨综合体 (TFCC) 和远距离放射性关节 (DRUJ) 的感觉内置.
提供解剖学数据,以指导和完善手腕中神经缩手术的神经目标.

主要方法:

剖析10个上肢的尸体样本从骨中部到指尖.
在放大镜下,详细分析提供第一个CMC关节,RCJ,TFCC和DRUJ的神经分支.
评估神经与目标关节的直接内化和近距离 (<2毫米).

主要成果:

第一个CMC关节始终从中枢神经的复发分支 (RBM) 和侧面前臂皮神经 (LABCN),辐射神经的表面分支 (SBRN) 和肘部神经的手掌皮神经分支 (PCBUN) 接受内化.
在RCJ,DRUJ和TFCC中,多个神经被内化或接近,包括前骨髓神经 (AIN),后骨髓神经 (PIN),LABCN,PCBUN和骨神经的背部皮层分支 (DCBUN).
每个关节都记录了直接内化和近距离的特定模式,并指出了一些变化.

结论:

第一个CMC,RCJ,TFCC和DRUJ存在一个一般的内化模式.
这些发现为手腕神经损伤提供了特定的神经点,

Muscles of the Forearm that Move the Hand and Fingers

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Spinal Nerves: Plexus I

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...
