Anatomical relationships between the radial nerve, the deltoid muscle insertions and several bony landmarks have been investigated to assess the feasibility of surgical transfer of the deltoid transfer during humeral osteotomy. Eleven embalmed human specimens were dissected. Each specimen included the whole thorax, both shoulders and upper limbs. Spatial position of the radial nerve along the radial groove, the deltoid muscle, and several anatomical landmarks was digitised using a three-dimensional (3D) digitiser. Sixteen distances and one angle characterizing the relationships between the path of the radial nerve and the landmarks were processed. Results showed that the average distance between the emergence of the radial nerve from the lateral intermuscular septum and the most distal insertion point of the deltoid muscle on the humeral bone shaft was 47.6 +/- 18.5 mm. The angle between a line extending from the entry of the radial nerve into the radial sulcus and its point of emergence (REN-REM line), and on the other hand a line running from the radial emergence and the deltoid muscle tip (REM-DELTIP line) was in average 23.5 +/- 6.7 degrees . The length of four lines running perpendicular to REM-DELTIP and crossing each quarter of the REN-REM line were interpolated. The length of these four lines was, from proximal to distal, 31.3 +/- 11.5 mm; 23.0 +/- 7.8 mm; 16.5 +/- 6.2 mm; and 7.6 +/- 2.6 mm, respectively. These results described in a quantitative way the path of the radial nerve in respect to the humeral bone and the deltoid muscle. These data will be used for further development of a humeral osteotomy protocol taking into account the spatial position of the radial nerve to orientate safely the surgical tools used to cut the humeral shaft.
为评估肱骨截骨术中三角肌转移手术的可行性,研究了桡神经、三角肌止点与多个骨性标志之间的解剖关系。解剖了11具防腐处理的人体标本。每个标本包括整个胸部、双肩和上肢。使用三维(3D)数字化仪对桡神经沿桡神经沟、三角肌及多个解剖标志的空间位置进行数字化处理。处理了16个距离和1个角度,以表征桡神经路径与这些标志之间的关系。结果显示,桡神经从外侧肌间隔穿出点与三角肌在肱骨干上最远端止点之间的平均距离为47.6±18.5毫米。从桡神经进入桡神经沟的入口点到其穿出点的连线(REN-REM线),与从桡神经穿出点到三角肌尖端的连线(REM-DELTIP线)之间的夹角平均为23.5±6.7度。内插了四条垂直于REM-DELTIP并与REN-REM线的每个四分之一相交的线的长度。这四条线从近端到远端的长度分别为31.3±11.5毫米、23.0±7.8毫米、16.5±6.2毫米和7.6±2.6毫米。这些结果以定量方式描述了桡神经相对于肱骨和三角肌的走行。这些数据将用于进一步制定肱骨截骨方案,该方案会考虑桡神经的空间位置,以便安全地定位用于切割肱骨干的手术工具。
