在制作一成年男性右上肢标本时,见桡侧腕短屈肌伴掌长肌副腱一例。此变异罕见,为积累国人解剖学数值资料,现报道如下。在去除前臂浅筋膜,分离肌肉、肌腱时,见一变异肌。该变异肌起自桡骨外侧下1/4处,附着于骨面,起点宽1.98 cm,其肌束由外上斜向内下,位于旋前方肌浅面,走行于桡侧腕屈肌腱和 In the production of an adult male right upper extremity specimens, see the radial wrist short flexor with palmar longus accessory tendon a case. This variation is rare, for the accumulation of Chinese anatomical numerical data are reported below. In the removal of forearm superficial fascia, muscle, tendon, see a variant muscle. The variation of the muscle from the radial outside the 1/4, attached to the bone surface, the starting point width of 1.98 cm, the muscle bundle from the outside oblique upward and downward, located in the pronated muscle shallow surface, walking in the radial wrist flexor tendon and
