Abstract

INTRODUCTION

Nerve can be compressed when traveling through any osteo-fibrous tunnel. Any eventual anatomic structure limiting this passage increases the risk of neuropathy. During dissection of the shoulder region we recognized a vein travelling on the inferior border of the suprascapular notch together with the suprascapular nerve. The aim of this work was to evaluate the morphological characteristics of this vein in cadaveric material.

MATERIALS AND METHODS

The suprascapular notch (SSN) region was dissected in 60 cadaveric shoulders. The course, number and diameter of nerve and vessels in the suprascapluar notch region were evaluated. Length, proximal and distal width of the superior transverse scapular ligament were measured. Photographic documentation was taken to evaluate the suprascapular nerve passage area.

RESULTS

The vein identified was named as the suprascapular notch vein. It was present in 58.3% of shoulders. In 11 specimens, it was double. Its mean diameter was 1.7 mm (SD 0.7 mm) and did not correlate with the suprascapular nerve passage area. A suprascapular notch vein co-occurred more often with the anterior coracoscapular ligament (ACSL). In comparison with the SSN without the ACSL, it has a significantly greater diameter (2 mm; SD 0.7 mm vs 1.5 mm; SD 0.6 mm, respectively; P=0.021).

CONCLUSIONS

The suprascapular notch vein was a common structure that did not replace the suprascapular vein. Its presence correlated with the occurrence of the ACSL and was independent of body side, STSL type and SSN type.

Observational anatomic study.

摘要

引言

神经在穿过任何骨纤维隧道时都可能受到压迫。任何限制其通过的解剖结构都会增加神经病变的风险。在肩部区域解剖过程中，我们发现一条静脉与肩胛上神经一起走行于肩胛上切迹的下缘。本研究的目的是评估该静脉在尸体标本中的形态特征。

材料与方法

对60具尸体肩部的肩胛上切迹（SSN）区域进行解剖。评估肩胛上切迹区域神经和血管的走行、数量及直径。测量肩胛上横韧带的长度、近端和远端宽度。拍摄照片记录肩胛上神经通过区域。

结果

所发现的静脉被命名为肩胛上切迹静脉。58.3%的肩部存在该静脉。在11个标本中，该静脉为双支。其平均直径为1.7毫米（标准差0.7毫米），与肩胛上神经通过区域无相关性。肩胛上切迹静脉与喙肩韧带（ACSL）同时出现的情况更为常见。与没有ACSL的SSN相比，其直径明显更大（分别为2毫米；标准差0.7毫米和1.5毫米；标准差0.6毫米；P = 0.021）。
