“…Muscle fusion between the VL and VI has been reported in previous studies (Willan et al, 1990;Becker et al, 2009). In an extreme case, the VL and VI could not be distinguished and the extensor apparatus of the knee could be regarded as possessing only three muscle heads (Frohse and Fr € ankel, 1913).…”

“…Recent anatomical studies of the QF have frequently distinguished the longitudinal and oblique parts of the VL (Becker et al, 2009). However, because these two parts and their relationships to each other have not been clearly defined (Vieira, 2011), the muscle belly in the inferolateral part of the thigh has been regarded as either the oblique part of the VL (Hallisey et al, 1987; Bevilaqua- Grossi et al, 2004) or the lateral part of the VI (Tomita et al, 2015).…”

Structural diversity of the vastus intermedius origin revealed by analysis of isolated muscle specimens

The quadriceps femoris (QF), a major extensor of the knee joint, plays an important role in human movement. However, descriptions of the three vastus muscles of the QF in anatomy textbooks remain confusing. We analyzed 33 QFs by a novel approach, using isolated muscle specimens to clarify the structures of the vastus lateralis (VL), vastus medialis (VM), and vastus intermedius (VI) origins. The origins of the VL and VM were quite constant in shape and location, but the VI was much more structurally diverse. In typical cases (23 of 33), the origin of the VI attached muscularly to the anterior and lateral surface of the femoral shaft. It adjoined the origin of the VL at the lateral lip (LL) of the linea aspera to form a common origin. In some cases (10 of 33), the muscle belly and origin of the VI were much smaller than those in the typical cases; the origin of the VI attached only to the anterior surface of the femur and did not contact the LL. In addition, the muscle belly of the VI was narrow and almost corresponded to the width of the femoral shaft. The isolated muscle specimen is a useful tool for analyzing individual muscle structures, which can be difficult to observe by routine dissection. Using this method, it became clear that the VI is more structurally diverse in its origin than the VL and VM. Clin.

“…It is composed of 4 muscle bellies: the rectus femoris (RF), which lies in the anterior portion of the thigh; the vastus medialis (VM) and vastus lateralis (VL) on the inner and outer portions, respectively; and the vastus intermedius (VI), which is located posteriorly [5]. The vastus muscles originate from the anterior, medial, and lateral aspects of the femur.…”

Lesions of the quadriceps muscle (QM) are frequently seen by sonographers, and in most cases they are the result of sports-related trauma. An accurate assessment of the severity of the lesion is essential, particularly when the patient is a professional athlete. In most cases, careful history-taking and a thorough physical examination are sufficient for making the diagnosis and indicating the most suitable imaging studies for each case. Clinical assessment alone, however, may not be sufficient for distinguishing contusions from small, partial tears or for estimating the size of a tear. Therefore, at least in patients who are professional athletes, imaging studies are necessary to plan appropriate therapy that will allow prompt functional recovery.Muscles cannot be visualized with conventional radiography, but it is used routinely in prepubertal patients because it can detect apophyseal detachments, which are the most frequent muscle lesion in this age group. Radiography is also useful when myositis ossificans is suspected. Magnetic resonance imaging, thanks to its excellent tissue contrast, allows simultaneous assessment of muscle, joint, and bone planes. It remains a second-line study due to its high cost and relatively low availability. It is also associated with various contraindications, the most important of which is the presence of a cardiac pacemaker. Ultrasonography has a number of advantages, including widespread availability, absence of contraindications, and low cost. It can also be used for dynamic studies of the muscle during contraction and relaxation, and if doubts arise, scans can easily be obtained of the contralateral muscle for comparison purposes. These qualities make it an excellent tool for follow-up of patients with QM lesions, when follow-up is necessary. This article reviews the anatomy of the QM, the technique used for standard ultrasound examination of this muscle, its normal appearance on ultrasound, and the sonographic characteristics of the most common traumatic lesions that affect it.Sommario Le lesioni del muscolo quadricipite (MQ) sono frequenti nella pratica ecografica quotidiana e, nella gran maggioranza dei casi, sono secondarie a traumi, per lo più sportivi. Un'accurata valutazione della gravità delle lesioni è necessaria, in particolare quando siano coinvolti sportivi di alto livello. * Corresponding author. CIM SA, Route de Malagnou 40a,

“…This type of study provides a summary of the existing research on a specific question, using explicit and systematic methods of identification, critical appraisal, and synthesis of scientific literature (Sacket et al; e.g., Gross Morphology of the Vastus lateralis Muscle: An Anatomical Review (Becker et al, 2009)). These studies may or may not comprise meta-analysis (statistical tool for combining the results of these studies by obtaining aggregates; e.g., Single site meta-analysis of 6% hydrogen peroxide whitening strip effectiveness and safety over 2 weeks (Gerlach et al, 2009)).…”

SUMMARY:Evidence-based medicine (EBM) employs the best available evidence in a particular time and context to solve specific clinical problems. This method of practicing medicine has been adopted by most of the disciplines involved in medical training; however, morphology appears to remain beyond this paradigm. The first step in evidence-based practice based on morphology is to recognize the types of studies being conducted with regard to morphology, followed by the assessment of the level of evidence that they provide, which is the purpose of this study. We designed a bibliometric study, in which journals in the Master Journal List of Thomson Reuters, selected using the keywords "Morphology" or "Anatomy," available between 2007 and 2008, with access to full text in electronic version, whose languages were English and Spanish, and which only considered studies on human morphology, were included. We analyzed a total of 790 articles, of which 93.1% were descriptive, 6.5% were analytical, and 0.4% were experimental design types. According to the stage of the study, most of the articles (94.8%) accounted for prevalence and differential diagnosis studies, concentrating on numerous designs such cross-section, which gave complex evidence (1c). The use of these methodologies for the systematic morphological knowledge allowed us to widen our research to generate clinically useful recommendations or merely a teaching approach based on the systematic morphological knowledge available.
