A Variation at Insertion Tendon of Tibialis Anterior

During roution dissection classes in 2011 in the Department of Anatomy, an anomalous insertion of the tibialis anterior tendon was observed on the left side of a formalin-fixed cadaver of a middle aged man without any trace of scars, adhesions or signs of trauma or operation. The insertion of the tibialis anterior tendon was on medial cuneiform only by one slip. The tibialis anterior is an important muscle because of its function and its use in tendon transfer as a treatment of recurrent congenital clubfoot and paralytic equinovarus foot deformities in cerebral palsy and arthroscopy. Morphology of the tibialis anterior muscle is important for its implications in minimally invasive plate osteosynthesis of tibial fractures. The insertion of the tendon of the tibialis anterior muscle may be related to pathologic changes of the foot and in particular, hallux valgus. Morphologic data should enable evaluation of such a relationship and perhaps offer a basis for improved therapy.
