During a routine dissection of an adult embalmed male cadaver for educational purpose in the department of anatomy at AIIMS, New Delhi, India, a rare unilateral variation of extensor digitorum longus (EDL) was found which is a muscle of anterior compartment of the leg. There was a split tendon of EDL muscle in the anterior compartment of left leg which became a common tendon in front of the ankle joint. This common tendon of EDL muscle again divided into four slips and were inserted in to the lateral four toes. In the upper part of the leg, the anterior tibial vessel and deep fibular nerve lie between the EDL and tibialis anterior. Knowledge of this type of anomaly is useful in diagnosis and treatment of compartmental syndrome. One of the tendon from the split tendon of EDL muscle can be used as a graft in tendon replacement surgeries. The split tendon may also be capable for some precise movements of the toes.
在印度新德里全印医学科学研究所解剖学系，为教学目的对一具成年防腐男性尸体进行常规解剖时，发现了一种罕见的趾长伸肌（EDL）单侧变异情况，该肌肉位于小腿前侧肌间隔。左侧小腿前侧肌间隔内的趾长伸肌肌腱出现了分裂，在踝关节前方形成了一条共同肌腱。这条趾长伸肌的共同肌腱再次分成四条腱束，并分别插入外侧四个脚趾。在小腿上部，胫前血管和腓深神经位于趾长伸肌和胫骨前肌之间。了解这种类型的异常情况，对骨筋膜室综合征的诊断和治疗很有帮助。趾长伸肌分裂肌腱中的一条肌腱可在肌腱置换手术中用作移植物。分裂肌腱或许也能够实现脚趾的一些精确运动。
