Abstract

Purpose: This study aimed to classify variation in morphology of the suprascapular nerve (SSN), suprascapular artery (SSA), and suprascapular vein (SSV) in relation to the superior transverse scapular ligament (STSL) at the suprascapular notch (SN) to evaluate the risk of vascular injury during SSN release.

Methods: Dissections were performed on 104 shoulders to analyze the morphology of the SSN, SSA, and SSV at the SN. The superior transverse scapular ligament (STSL) was evaluated for dimensions, ossification, and impact on SN morphology. Configurations of the nerve and vessels were categorized, and vascular injury risk was stratified as low, moderate, or high.

Results: The SSN passed beneath the STSL in 99% of shoulders, while the SSA and SSV configurations varied. Low vascular injury risk was identified in 82% of shoulders, moderate risk in 10.6%, and high risk in 7.4%, with female cadavers demonstrating higher risk anatomy (13.3%) compared to males (2.0%). Ossified STSLs were significantly associated with smaller SN dimensions, including reduced height and width (p < 0.001).

Conclusion: Anatomical variations at the SN play a critical role in determining the risk of vascular injury during SSN release. Surgeons should consider these morphological differences, particularly in cases involving ossified STSLs or higher-risk configurations, to optimize surgical planning. This study underscores the importance of precise anatomical knowledge for minimizing complications in suprascapular procedures at the SN.

肩胛上神经和肩胛上切迹血管形态的变化：肩胛上神经释放的临床意义。

目的：本研究旨在分类肩胛上神经（SSN）、肩胛上动脉（SSA）和肩胛上静脉（SSV）与肩胛上横韧带（STSL）在肩胛上切迹（SN）上的形态变化，以评估肩胛上横韧带释放时血管损伤的风险。方法：对104个肩关节进行解剖，分析肩关节的SSN、SSA和SSV的形态学。评估上横肩胛骨韧带（STSL）的尺寸、骨化情况和对骶髂关节形态的影响。神经和血管的结构被分类，血管损伤风险被分层为低、中、高。结果：99%的肩部SSN通过STSL，而SSA和SSV的配置不同。82%的肩部存在低血管损伤风险，10.6%为中等风险，7.4%为高风险，女性尸体的解剖学风险（13.3%）高于男性（2.0%）。骨化的STSLs与较小的SN尺寸显著相关，包括高度和宽度降低(p结论：SN的解剖变异在确定SSN释放时血管损伤的风险中起关键作用。外科医生应考虑这些形态学差异，特别是涉及骨化STSLs或高风险配置的病例，以优化手术计划。本研究强调了精确的解剖学知识对于减少肩胛上手术并发症的重要性。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
