股中间张肌(TVI)是新近发现的一种位于股前外侧的肌肉，被认为是股四头肌的第五支肌群。已经有几篇论文详细描述了它的解剖和形态特征；然而，这种肌肉的许多特征，如它的本体论或动力学功能，仍然不清楚。本研究的目的是确定TVI肌在人类胚胎发育过程中的初始形态，并研究其生长发育情况。对21、22、23个卡内基期(Carnegie Stage，CS)人胚胎15个30条小腿(冠臀长18.7~28.7 mm)进行了组织学观察。在CS22的10条肢体中，有7条在股外侧肌与中间肌之间观察到TVI的肌细胞团，提示TVI发生在这一时期。在CS 23中，除1例标本外，其余标本均可见TVI。然而，在这些胚胎阶段，既没有观察到TVI的腱结构，也没有观察到TVI的腱结构。传统的股四头肌四部分的形成是在CS21内完成的；因此，我们的结果表明，TVI是股四头肌复合体中最后一个发育的元素。推测在胚胎期后，TVI继续生长，同时形成朝向膝盖骨的腱结构，并接受某些血管分支的血管供应。这些发现的临床意义在于，在大腿前外侧(ALT)区域内进行手术的骨科医生和整形外科医生应该了解TVI的解剖和发展，以减少手术并发症。我们目前的研究旨在更深入地了解TVI和其他股骨伸肌的形态发生。
The tensor vastus intermedius (TVI) is a newly discovered muscle located in the anterolateral thigh area and is considered the fifth component of the quadriceps femoris muscle. There have been several papers describing its anatomical and morphological features in detail; however, many features of this muscle, such as its ontology or kinetic functions, remain unknown. The purpose of this study was to determine the initial appearance of the TVI muscle in human embryonic development and to investigate its growth and development. Histological observations were performed on 30 lower limbs of 15 human embryos from Carnegie stage (CS) 21, 22, and 23 (with crown‐rump length ranging from 18.7 to 28.7 mm). Myocyte clusters of the TVI were observed between the vastus lateralis and intermedius muscles in 7 out of 10 limbs in CS 22, indicating that the TVI arises during this stage. In CS 23, the TVI was clearly present in all specimens except one. However, neither the aponeurosis nor the tendonous structure of the TVI were observed in these embryonic stages. Formation of the conventional four components of the quadriceps muscle is completed within CS 21; therefore, our results suggest that the TVI is the last element to develop in the quadriceps femoris complex. It is posited that after the embryonic period, the TVI continues to grow, while forming the tendinous structure toward the patella and receiving vascular supply from certain vascular branches. The clinical significance of these findings is that orthopedists and plastic surgeons who perform surgical procedures within the anterolateral thigh (ALT) area should be aware of the anatomy and development of the TVI in order to reduce surgical complications. Our present research aims to contribute to a deeper understanding of the morphogenesis of the TVI and the other femoral extensor muscles.
