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.
Cadaveric dissection of left thigh of a 72-year-old man was performed for research and teaching purposes at the Department of Anatomical 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.
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 vastus medialis muscle.
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 stabilisation.
我们报告一例股四头肌（QF）合并中间肌双层张量（TVI）肌肉及新型第六头肌的病例。
在罗兹医科大学解剖学解剖与捐赠系，为研究和教学目的对一名72岁男性的左大腿进行尸体解剖。按照严格指定的方案，使用标准技术对左下肢进行解剖。对肌肉的每个头进行拍照并进一步测量。
解剖过程中观察到一种不寻常类型的TVI肌肉。它由浅、深两个面组成。此外，QF肌肉的第六头从股内侧肌长出。
在肌肉拉伤的诊断过程中，了解QF肌肉额外头的存在及其可能的变异情况是必要的。此外，根据肌腱的走行，这些头可能参与髌骨稳定。
