During a cadaver dissection in a gross anatomy course, a flexor digitorum accessorius longus (FDAL) muscle was identified. The FDAL was a unilateral, two-headed, multipennate muscle originating from the flexor retinaculum, deep fascia, and calcaneus. The muscle bodies fused into one tendon and coursed distally where slips were observed inserting into the flexor digitorum longus tendon and the flexor hallicus longus tendon. A survey of the literature revealed that an FDAL may be present in approximately 15% of the general population. Our results concerning the FDAL suggest the need for clinicians to recognize the occurrence and variability of accessory leg and ankle muscles, and to use available technology such as MRI to assist with the diagnosis and treatment of compressive neuropathies of the foot.
在一次大体解剖课程的尸体解剖过程中，发现了一块副长屈肌（FDAL）。FDAL是一块单侧、双头、多羽状肌，起自屈肌支持带、深筋膜和跟骨。肌腹融合成一条肌腱，向远端走行，可见腱束插入到趾长屈肌腱和拇长屈肌腱。文献调查显示，普通人群中约15%可能存在FDAL。我们关于FDAL的研究结果提示临床医生有必要认识到小腿和踝关节附属肌肉的发生情况及变异性，并利用MRI等现有技术辅助足部压迫性神经病变的诊断和治疗。
