用旋前方肌肌桥修复正中神经缺损的应用解剖

The pronator quadratus:A muscular bridge for median nerve defects

在30侧成人上肢标本上,观测了旋前方肌的形态和血供.旋前方肌血供来自骨间前动脉、桡动脉和尺动脉的旋前方肌肌支.肌的血供主要来自骨间前动脉,以骨间前血管为蒂,依据神经损伤平面的不同,可设计以旋前方肌上、中、下不同部位的肌桥为桥接体、

Muscular bridge has been proven both clinically and experimentally to be valid in guiding the peripheral ne- rve regeneration through the nerve defects. However,in the vicinity of wrist all the muscles become muscular tendons, and the preparation of the muscular bridge in this region beco- mes particularly difficult. This paper presents the anatomy of the pronator quadratus which is mainly supplied by the anterior interosseous artery. Pedicled with this artery, a vascula- rized muscular bridge can be formed, which may be used for the treatment of median nerve defects.
