Abstract

BACKGROUND The aim of this study was to qualitatively and quantitatively describe the anatomy of the QT including its size, its layers and relationship between layers. METHODS Sixty lower limbs (15 females and 15 males fixed in 10% formalin were examined. A retrospective analysis of 20 thigh MRI examinations was performed (10 males, and 10 females). RESULTS In all dissected specimens, the quadriceps femoris was composed of 4 layers: superficial (first layer), middle (second layer), middle-deep (third layer) and deep (fourth layer). The first layer (superficial) was formed by the rectus femoris tendon and fascia. The second layer was composed of tendons of the vastus medialis and superficial part of the vastus lateralis. The third layer was formed by the intermediate part of the vastus lateralis. The fourth layer was composed of the tendon of the vastus intermedius. This type of anatomy was visualized in 4 males and 2 female on MRI scans. CONCLUSION The findings of this study provide a detailed anatomy of the quadriceps tendon. There were 4 different layers of the QT consistently found in all specimens. The first layer was independent and composed by the rectus femoris tendon, the second was formed by the superficial part of the vastus lateralis and vastus medialis. The third layer was formed by the intermediate part of the vastus lateralis, and the deepest fourth layer was composed of the vastus intermedius. This detailed structural anatomy was also able to be visualized on MRI scans.
对股四头肌肌腱的新观察——它真的由三层组成吗?
本研究的目的是定性和定量地描述QT的解剖结构,包括其大小、层数和层间关系。方法对60例下肢(女15例,男15例)进行10%福尔马林固定检查。回顾性分析20例大腿MRI检查(10例男性,10例女性)。结果在所有解剖标本中,股四头肌由4层组成:浅层(第1层)、中层(第2层)、中深层(第3层)和深层(第4层)。第一层(浅层)由股直肌肌腱和筋膜组成。第二层由股内侧肌和股外侧肌的浅层肌腱组成。第三层由股外侧肌中间部分形成。第四层由股中间肌肌腱组成。在MRI扫描中,4名男性和2名女性可见这种解剖结构。结论:本研究结果提供了股四头肌肌腱的详细解剖。在所有标本中均发现4种不同的QT层。第一层是独立的,由股直肌肌腱组成,第二层由股外侧肌和股内侧肌的表面部分组成。第三层由股外侧肌中间部分组成,最深的第四层由股中间肌组成。这种详细的结构解剖也能够在MRI扫描上可视化。
