A previously unreported variation related to the insertion of the tibialis anterior muscle and the superficial fibular (peroneal) nerve.
During dissection classes in 2003 in the Department of Anatomy at Ege University Faculty of Medicine, an unexpected variation of the insertion of the tibialis anterior tendon was determined on the right side of a formalin-fixed cadaver of a 40-year-old man without any trace of scars, adhesions or signs of trauma or operation. The insertion of the tibialis anterior tendon was very abnormal, not on the medial side of the foot but on the lateral side. The tibialis anterior is an important muscle because of its function and use in tendon transfer as a treatment of recurrent congenital clubfoot and paralytic equinovarus foot deformities in cerebral palsy and arthroscopy, as discussed herein.
