A previously undescribed accessory flexor digitorum superficialis muscle-tendon unit was discovered on surgical exploration of the wrist in an 18-year-old girl with symptoms of distal ulnar neuropathy and a volar soft-tissue mass. Excision of the muscle-tendon unit resulted in complete resolution of symptoms. The preoperative diagnosis of an accessory muscle is difficult, being commonly mistaken for synovitis, ganglia, or tumor.
在对一名患有尺神经远端神经病症状和掌侧软组织肿块的18岁女孩进行手腕手术探查时，发现了一个此前未被描述过的额外的指浅屈肌腱单元。切除该肌腱单元后症状完全缓解。额外肌肉的术前诊断很困难，通常会被误诊为滑膜炎、腱鞘囊肿或肿瘤。
