Abstract
Background: We present a case report of quadriceps femoris (QF) with co-existing bilaminar tensor of the vastus intermedius (TVI) muscle and new type of sixth head.Materials and methods: Cadaveric dissection of left thigh of a 72-year-old man was performed for research and teaching purposes at the Department of Anatom-ical Dissection and Donation, Medical University of Lodz. The left lower limb was 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 con-sisted of two surfaces, superficial and deep. In addition, sixth head of QF muscle grew out from the vastus medialis muscle.Conclusions: The knowledge of the existence and possible variations of addition-al 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 stabilisation. (Folia Morphol 2022; 81, 4: 1082-1086)
