摘要：

 目的 探讨肘肌的形态、肌构筑学指数和肌内神经密集区的分布模式，为肘关节后外侧入路手术及肘肌肌瓣移植提供解剖学定位。   方法 选取成人肘肌共10例，平均年龄64.2岁，采用大体解剖法、肌构筑学指数法和改良Sihler肌内神经染色法。   结果 肘肌近似三角形，肌湿重（6.31±0.85）g，肌长（6.24±0.78）cm，肌纤维长（4.74±0.88）cm，羽状角（70.60±6.41）°，肌生理横切面积（0.41±0.15）cm2。桡神经深支的分支在距起点肌腹长26.17%处分成上、中、下3支至肘肌中部，吻合形成丛。   结论 肘肌为半羽肌；依据肌内神经密集区的位置，可考虑行肘肌肌瓣移植及靠近肌的下部行肘关节后外侧手术入路。

Abstract:

 Objective  To study the morphology, muscle architecture index and distribution pattern of intramuscular nerve dense area of elbow muscle, so as to provide anatomical location for poster-lateral approach of elbow joint and transplantation of elbow muscle flap.    Methods Through gross anatomy, muscle architecture index and modified Sihler’s intramuscular nerve staining, 10 cases with an average age of 64.2 years were selected.    Results  The elbow muscle was approximate triangle, the muscle wet weight was (6.31±0.85) g, the muscle length was (6.24±0.78) cm, the muscle fiber length was (4.74±0.88) cm, pennation angle（70.60±6.41）°and the muscle physiological cross-sectional area was (0.41±0.15) cm2. The branches of the deep branch of the radial nerve were divided into upper, middle and lower branches at the distance of 26.17% from the abdominal length of the starting muscle to the middle of the elbow muscle, and anastomosed to form a plexus.    Conclusion The elbow muscle is hemi-pennate muscle；According to the location of intramuscular nerve dense area, elbow muscle flap transplantation can be considered，the posterolateral approach of elbow joint can be performed near the lower part of muscle.
