Abstract

Background: We present a case report of Quadriceps Femoris (QF) with co-existing bilaminar Tensor of the vastus intermedius muscle (TVI) and new type of sixth head. Materials and methods: Cadaveric dissection of left thigh of a 72 years old was performed for research and teaching purposes at the Department of Anatomical Dissection and Donation, Medical University of Lodz. The left lower limb were dissected using standard techniques according to a strictly specified protocol. Each head of the muscle was photographed and subjected to further measurement. Results: During dissection, an unusual type of TVI muscle was observed. It consisted of two surfaces, superficial and deep. In addition sixth head of QF muscle grew out from the VM muscle. Conclusions: The knowledge of the existence and possible variations of additional heads of QF muscle is necessary during diagnostic process of muscle strains. Moreover, according to course of tendons that heads may take part in patella stabilization.
