概括
这项研究确定了精确的神经块的解剖学标志,这些神经块准前骨,后骨和表面辐射神经. 这些阻塞旨在改善远端半径骨折手术后的疼痛管理,并减少慢性疼痛风险.
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
- 疼痛管理 疼痛管理
背景情况:
- 距离半径骨折很常见,特别是在年轻和老年人群中,需要有效的术后疼痛控制.
- 骨折后手术疼痛管理不足可能导致慢性区域疼痛综合征 (CRPS) 等并发症.
- 目前远半径骨折的止痛策略包括区域麻醉和神经阻塞,但有针对性的方法正在发展.
研究的目的:
- 研究一种用于远端半径骨折修复的新型神经阻塞策略,准前侧骨际神经 (AIN),后侧骨际神经 (PIN) 和辐射神经 (SBRN) 的表面分支.
- 确定精确的解剖学标志,以优化在开放减少和内部固定 (ORIF) 期间在这些神经周围的局部麻醉透.
- 为了增强术后疼痛缓解,并可能减轻CRPS的风险,在外科治疗远半径骨折后.
主要方法:
- 在15个尸体前臂样本上进行了解剖剖,以绘制AIN,PIN和SBRN的轨迹.
- 建立了靠近李斯特结核的参考点,以测量神经距离和相对于骨和动脉标志的解剖位置.
- 记录了目标神经的带出口点和辐射/节或手掌/背部位置.
主要成果:
- 辐射神经的表面分支 (SBRN) 离开了距离李斯特结核大约69.8毫米的侧膜,具有可变的辐射/手掌定位.
- 前骨间神经 (AIN) 位于距离边缘4.7毫米,通常是与其伴随的动脉 (80%的病例) 径向的.
- 后部骨间神经 (PIN) 距离关边缘6.7毫米,通常是关至其动脉 (63.6%的病例).
结论:
- 这种解剖学研究为在SBRN,AIN和PIN附近精确地注射局部麻醉剂提供了关键的地标.
- 已识别的标志可以指导外科医生进行向的神经阻塞,以改善外科术后疼痛控制后ORIF的远半径骨折.
- 这种方法有望减少阿片类药物依赖,并降低手术修复的患者中CRPS的发生率.

Bones of the Upper Limb: Radius
4.5K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

Bones of the Upper Limb: Ulna
4.2K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Spinal Nerves: Plexus I
2.4K
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.

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.2K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
