Peroneus tertius (PT) is frequently used as a free muscle flap to treat the soft tissue defects and osteomyelitis, in the lower limb as it is functionally insignificant while balancing the foot during walking. The morphology of the PT is highly variable. In the present case we report a rare case of unusual morphology of the PT in a formalin embalmed male cadaver. At the level of ankle, PT divided into three tendons; two of them were inserted to the base of the distal phalanx of the fifth toe and base of the fifth metatarsal bone respectively. The smaller third tendon was attached to the fascia covering the capsule of the ankle joint. Further, extensor digitorum longus (EDL) gave only three tendinous slips for the second, third and fourth toes.
第三腓骨肌(PT)常被用作游离肌瓣,用于治疗下肢的软组织缺损和骨髓炎,因为它在行走时平衡足部功能方面作用不大。第三腓骨肌的形态高度可变。在本病例中,我们报告了一例在福尔马林防腐的男性尸体中第三腓骨肌形态异常罕见的病例。在踝关节水平,第三腓骨肌分为三条肌腱;其中两条分别附着于第五趾远节趾骨基部和第五跖骨基部。较小的第三条肌腱附着于覆盖踝关节囊的筋膜。此外,趾长伸肌(EDL)仅为第二、第三和第四趾发出三条腱束。
