摘要
目的 从解剖和电生理探讨背阔肌分区的可行性及实用性 ,以便指导临床应用。方法 1对 10具成人尸体进行背阔肌内的血管和神经解剖 ,按主要血管、神经的分支分布 ,将背阔肌分区。 2利用体表电极记录 13例 (2 5侧 )健康成人背阔肌不同分区在肩关节运动中的肌电表现 ,将记录结果进行统计学处理。 3应用外下区背阔肌岛状肌皮瓣支配范围 ,为 10例行乳房再造、肘关节及胸壁瘢痕创面的修复。 结果 1背阔肌内的主要血管神经分内、外侧两支 ,按内、外侧将背阔肌分成内上和外下二区。 2二区在肩关节运动中的肌电表现不同。 3分区应用背阔肌肌皮瓣行乳房再造、肘关节及胸部瘢痕创面修复均取得满意效果。 结论 背阔肌可以分为二区并可分开应用 ,外下区较内上区在肩关节运动中起的作用大。
Objective To investigate the feasibility of segmentation of latissimus dorsi on the basis of anatomy and electrophysiology. Methods Ten cadaveric latissimus dorsi was dissected according to the blood supply, nerve innervation. Electromyelogram(EMG) of latissimus dorsi of 13 healthy persons was recorded with superficial electrode plate in the motion of shoulder joint. The results of record were managed with statistic methods. Ten patients(including reconstruction of breast and repair of scar on elbow joint and on chest wall ) were treated with the lateral inferior myocutaneous island flap. Results According to the medial and lateral vasculonervous branches, latissimus dorsi can be divided into the medial superior and lateral inferior segments. The clinical application of the segment achieved good results in reconstructing breast and in repairing scars on elbow and on chest wall. Conclusion Latissimus dorsi can be divided into two segments and applied separately. The lateral inferior segment is more useful in shoulder motion.
