The superior gemellus muscle is the higher placed gemellus muscle that arises from the outer (gluteal) surface of the ischial spine, and blends with the upper part of the tendon of the internal obturator. Residual edema signal intensity may persist in athletes that are clinically rehabilitated. (Tubbs R, ed.). Am J Sports Med 2005;33:745-764. WHO brain tumour classification has been updated in 2016. Vastus medialis muscle. Because the tendon of the direct head blends with the anterior fascia of the proximal third of the muscle, it may be difficult to distinguish a musculotendinous strain from an anterior myofascial injury. Unable to process the form. A muscle contusion occurs due to direct impact, usually with a blunt object, or by a fall to the ground. In this injury, a circumferential tear occurs through the peripheral fibers of the inner bipennate muscle, separating it from the overlying unipennate muscle. Avulsion fracture of the anterior inferior iliac spine with abundant reactive ossification in the soft tissue. 2 Department of Radiology, Kohinoor Hospital, Mumbai, Maharashtra, India . 2017;03(01):e9-e16. 16 Hsu JC, Fischer DA, Wright RW. AJR 1999;173:703-709. This tear involves muscle fibers and extends up to or through the investing epimysium and the overlying fascia. Most of the quadriceps tendon inserts on the anterosuperior surface of the patella. Axial proton density fat-suppressed image (15a): complete avulsion of the indirect head, replaced by fluid (short arrows). These muscles attach to the patella via the quadriceps tendon. It has been suggested that if the site of injury and swelling is compressed by the overlying sartorius muscle, healing may be delayed4,22,23. On the right, mild edema of the inner muscle, surrounding the central tendon (short arrow) and a mild posterolateral myofascial strain (arrowhead). It extends the entire length of. Quadriceps tendinosis is an overuse injury in athletes who perform intense and repeated jumping, as in volleyball, basketball, high jumping and long jumping. Most involve a period of rest, then slowly starting with gentle exercise until your body is healed. It causes intramuscular hemorrhage and edema and varying degrees of pain, tenderness, swelling and skin discoloration. The 2016 World Health Organization Classification of Tumors of the Central Nervo All contents copyrights with Sumer Sethi. Treating PFSS can also involve strengthening your hip muscles along with your vastus medialis. It is easily the most neglected muscle group in the lower body. Most quadricep injuries take at least six to eight weeks to recover. Clin Anat 2003;16:458-460. Quadriceps contusion is a common, disabling injury in those sports wherein the participants have no padding for the thigh and upper leg, such as soccer and rugby. Overlying medial patellofemoral ligament is intact, which is an important findings to be noted by MRI. The exception was a 14 year old patient with acute symptoms who had an AIIS avulsion fracture, partial tear of the direct head and no tear of the indirect head. Curr Orthop Practice 2012;23:390-392. MR imaging of myotendinous strain. The other components of the quadriceps mechanism are the vastus medialis (with its distal, oblique component), vastus intermedius and vastus lateralis. Figure 3 - Anatomy of the knee on a coronal slice (MRI) : meniscus (lateral and medial), cruciate ligaments, vastus (lateralis, intermedius, medialis), tibial and fibular collateral ligaments. . 15 Ouellette H, Thomas BJ, Nelson E, Torriani M. MR imaging of rectus femoris origin injuries. Current concepts in MRI of rectus femoris musculotendinous (myotendinous) and myofascial injuries in elite athletes. of 9 NEXT The four muscles combine to become the quadriceps tendon. The vastus medialis is part of the quadriceps muscle group. 9 Bordalo-Rodrigues M, Rosenberg ZS. Sagittal T2-weighted fat suppressed image: contusion of vastus intermedius muscle with large, intramuscular hematoma (arrows) containing clotted blood. These include renal disease, diabetes, hyperparathyroidism, collagen vascular disease, rheumatoid arthritis and gout and the use of steroids or fluoroquinolone antibiotics. Unique blend of academic excellence and entrepreneurship, heading leading firms in India- Teleradiology Providers, pioneering company providing teleradiology services and DAMS (Delhi Academy of Medical Sciences) Premier test preparation institute in India for MD/MS/MCI preparation. Assign atraumatic muscle disorders to one of four broad MR imaging-based patterns to generate a reasonable differential diagnosis. The rectus femoris muscle is the most anterior and superficial of the quadriceps muscle group. Neither remodelling, destruction or . IP = iliopsoas muscle, S = sartorius muscle, TFL = tensor fascia lata muscle, Gmin = gluteus minimus muscle, Gmed = gluteus medius muscle. As was described previously, avulsion fracture of the AIIS may heal with extensive heterotopic ossification, extending laterally and distally from the avulsion site, and this may be confused with an osteoblastic tumor. There is a section of the muscle called the VMO (vastus medialis oblique) which is said to be distinct from the rest of the muscle.It is not proven to be so but people believe that it is responsible for this ending stage of the lockout. If you injure the muscle, your normal functional ability may be affected. Point #2: In the top 15 degrees of the squat. Figure 4 - 3D pictures of the knee : anterior view showing the anatomy of the patella, femur, tibia, fibula and femorotibial joint. MR imaging of the quadriceps tendon: normal layered configuration and its importance in cases of tendon rupture. A grade 3 strain is defined as a complete tear of the musculotendinous junction and, on MRI, is characterized by discontinuity of all fibers, with or without muscle retraction. Injury to the vastus medialis can cause knee pain and difficulty walking, running, or managing stairs. Intramuscular degloving injury of the rectus femoris muscle. The vastus medialis originates from the intertrochanteric line on the inner part of your thigh bone (femur). These tears have a strong tendency to occur distal to the termination of the central tendon, such that this tendon is not seen distal to the usually proximally retracted inner muscle. For example, a third head, arising from the iliofemoral ligament and gluteus minimus tendon, was seen in a majority of cadavers2 and, in another study, 60% of cadavers had an oblique head of the vastus lateralis muscle with no oblique head of the vastus medialis muscle observed3. The quadriceps tendon usually ruptures transversely at the osteotendinous junction. They studied 9 patients with acute symptoms and 8 patients with chronic symptoms with rectus femoris origin injuries. 4. ADVERTISEMENT: Supporters see fewer/no ads. Axial proton density fat-suppressed image (17a): on the left, partial tear of the deep, central tendon with edema throughout the inner muscle (long arrow). The fourth element of the quadriceps is rectus femoris, described above. A sagittal T2-weighted fat-suppressed image (19b) reveals proximally retracted inner muscle and the central tendon (asterisk) with a large amount of surrounding fluid ( arrowheads) that extends 20 cm cephalocaudal. The quadriceps tendon is a multi-layered structure formed by the quadriceps muscle group. It is the most medial of the 3 muscles of the quadriceps (thigh) group. Muscle resistance within the quadriceps also reveals a weakness in the vastus medialis. MRI reveals intratendinous increased signal intensity on fluid-sensitive images and variable tendon enlargement. A 28-year-old female asked: Can the vastus medialis become a swollen bump and somewhat suddenly painful two days after working out? It has been suggested that the vastus muscles are less often affected by significant strain injury since they form a large muscle mass that acts synergistically, they only cross one joint and they are primarily composed of type I muscle fibers20. The vastus intermedius is a deep, non-visible muscle within the middle of the thigh. Scand J Med Sci Sports 1997;7:182-190. The tumour has a minimum internal enhancement and peritumoral oedema discrete. Quadriceps contusions. MRI: Intramuscular lesion located in right vastus medialis, with oval morphology and well defined contours, showing low signal intensity on T1-weighted sequences and high on T2-weighted sequences without fat component seen inside. Pelvic avulsion injuries usually involve skeletally immature patients and most often occur between the ages of 14 and 25 years. Therefore, it was assumed that injury to the direct head origin was more common than to the indirect head13,14. 2nd ed. Muscle and tendon may appear normal on T1-weighted images19. Axial proton density fat-suppressed images reveal an intrasubstance tear of the origin of the indirect head (short arrow) and of the direct head (long arrow). jelekin.2007.05.008 9. Exercises like heels slides and stationary bike riding may also be useful. ISBN:0702051314. This information is needed in order to determine prognosis, to formulate an appropriate plan for rehabilitation and, in some cases, for planning surgery. This was not borne out in a report of MR imaging of rectus femoris origin injuries in 17 patients by Oullette et al15. This injury usually involves the posterolateral aspect of the muscle and favors the proximal and middle thirds4. It has been proposed that distal displacement of the AIIS fracture fragment may be limited if the adjacent indirect head of the rectus femoris is intact11. Lee SH, Lee TJ, Woo MS, Kwon DG. Tribute to Roengten's Gesture of not Patenting Xrays. The others are the rectus femoris, the vastus intermedius, and the vastus lateralis. Treasure Island (FL): StatPearls Publishing. At its proximal aspect, this tendon is rounded and located within the medial aspect of the muscle. It is typically described as a trilaminar structure, with the vastus medialis and lateralis converging to form a middle layer. Skeletal Radiol 1996;25:580-584. Chief diagnostic radiology resident. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Oh G, Adams M, Knipe H, et al. The direct head extends along the proximal 1/3, the indirect head courses through the proximal 2/3 and the distal, posterior tendon arises from the aponeurosis at the posterior muscle surface. Acta Ortop Bras. DeLee and Drez's Orthopaedic Sports Medicine. It should be suspected if, after 2-3 weeks, symptoms worsen with loss of knee flexion and persistent swelling. ----------------------------------- Maffucci syndrome is characterized by benign enlargements of cartilage (enchondromas); bone deformities; and dark, irregularly shaped Radiology is an increasingly favored specialty for medical graduates. The most important active stabilizer of the patella is the vastus medialis oblique (VMO). Diffusion tensor imaging findings The femoral artery supplies blood to the vastus medialis. Being able to move your knee normal is necessary for walking, jumping, and climbing stairs. The function of your vastus medialis can be impaired by several conditions, which can result from surgery, trauma, or athletic injuries. If your goal is to strengthen the vastus medialis as fast as possible then there is no getting around it: you have to train with a full range of motion. Vastus medialis exercises are a great way to improve knee stability and function, reduce knee pain and reduce the risk of cartilage injuries. Am J Sports Med 1985;13:349-358. 2008 Dec 1;18(6):1032-7. doi: 10.1016/j. Clin Anat, 1993, 6:129-134. . 41st ed. It sits on the outside of the leg and comes together inward towards the knee. Because the rectus femoris consists of two muscles, a complete tear of the deep musculotendinous junction is really a grade 3 strain/tear of only the inner muscle. Am J Sports Med 1995;23:500-506. The fact that the patella sits atop the anterior surface of the femoral condyles, increases the angle at which the quadriceps tendon pulls on the shaft of the tibia. Case study, Radiopaedia.org (Accessed on 11 Dec 2022) https://doi.org/10.53347/rID-52835. Action: Extension of the stifle joint and tension of the fascia cruris. 20 year-old female with recurrent thigh strains and pain over the past 2 months. Background: Female athletes are more predisposed to anterior cruciate ligament (ACL) injuries in comparison with their male counterparts. Summary origin femur medial part of intertrochanteric line pectineal line medial lip of the linea aspera medial supracondylar line insertion quadriceps tendon Patients usually respond to conservative measures and tendon debridement/excision is performed for recalcitrant cases. If the injury is caused by impact or trauma, the doctor must take an X-ray to rule out the possibility of fracture or dislocation. 3 Waligora AC, Johanson NA, Hirsch BE. The vastus intermedius is a component of the quadriceps tendon including vastus lateralis, vastus medialis, and rectus femoris. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Physical therapists sometimes use a special type of neuromuscular electrical stimulation (NMES) to encourage the vastus contract properly and help regain normal muscle function.. The vastus medialis (Latin: musculus vastus medialis) is one of four muscles that compose one of the strongest muscle in the human body - the quadriceps femoris muscle. 35 year-old male with bilateral thigh pain. Jordana Haber Hazan, MD, is board-certified in emergency medicine and currently works as an academic emergency physician. Clinical History: A 16 year-old female track athlete presents with a 6 week history of a thigh mass and pain. American Academy of Orthopedic Surgeons (AAOS), Wilkinson R, Fischer S (ed.). 1, Patellar tendon. In prior studies utilizing radiography and CT, all proximal RF avulsions involved the AIIS, the site of attachment of the direct head, with no cases of avulsion of the superior acetabular ridge by the indirect head. (7b) More distally, the two heads converge to form the conjoined tendon (arrowhead). Tear of the deep musculotendinous junction of the indirect head was first described by Hughes et al in 1995 and is probably the most common tear of the RF tendon17. Normal proximal rectus femoris anatomy on axial STIR images. Background: To quantitatively and qualitatively assess vastus medialis muscle atrophy in asymptomatic patients with anterior cruciate ligament reconstruction, using the nonoperated leg as control.Methods: Prospective Institutional Review Board approved study with written informed patient consent.Thirtythree asymptomatic patients (men, 21; women,12) with ACLreconstruction underwent MR . Several military studies have shown a shorter rehabilitation time, especially for moderate and severe contusions, if the injured leg is placed in a position of flexion for the first 24 hours after injury to limit hematoma formation. 27 year-old female with chronic anterior hip pain, suspicious for a labral tear. Axial proton density fat-suppressed (CC) and sagittal T2-weighted fat-suppressed (DD) images: distal rectus femoris musculotendinous junction strain (long arrow) with thickened, scarred distal tendon (short arrow). The vastus medialis is innervated by the femoral nerve, which comes out from your lumbar spine at level two, three, and four. Limitation of motion and difficulty weight-bearing is seen with moderate or large contusions. The same mechanism of injury in a skeletally immature athlete results in avulsion fracture of the AIIS, at the origin of the direct head, owing to the vulnerability of the open apophysis. 4 Kassarjian A, Rodrigo RM, Santisteban JM. The terminating indirect head is barely visible (arrow). Magnetic resonance (MR) imaging is the imaging modality of choice for evaluation of acute traumatic musculotendinous injuries of the knee. 17 Hughes C, Hasselman CT, Best, Martinez S, Garrett WE Jr. The most significant of the other risk factors for muscle strain is recent or remote injury to the muscle. Since the vastus medialis is a major knee stabilizer, weakness in the muscle can be a cause of PFSS.. Radiology, 1993,188:575-578. Vastus Intermedius Origin: Superior 2/3 of anterior and lateral surfaces of femur; also from lateral intermuscular septum of thigh Insertion: Lateral border of patella; also forms the deep portion of the quadriceps tendon Action: Extends the knee Innervation: Muscular branches of femoral nerve Arterial Supply: Lateral circumflex femoral artery Rupture of the quadriceps tendon was first reported in the English literature by Samuel in 1838. vastus lateralis, medialis obliquus and medialis longus muscles. Scar may also encase the deep tendon. CT demonstrates mature and/or immature bone depending upon the age of the injury. Anterior iliac spine avulsion fracture. Radiology 39 years experience. Patients may present with acute or chronic symptoms and, often, the location, type and extent of injury are not readily determined by clinical assessment. 2013;25(4):230-232. doi:10.5792/ksrr.2013.25.4.230, Sheehan FT, Borotikar BS, Behnam AJ, Alter KE. 27 Verrall GM, Slavotinek JP, Barnes PG et al: Clinical risk factors for hamstring muscle strain injury: a prospective study with correlation of injury by magnetic resonance imaging. It has been proposed that this injury is distinct from the typical myotendinous injury and is primarily an intermuscular dissociation, rather than tearing along the longitudinally-oriented musculotendinous junction. The vastus medialis (vastus medialis oblique, or VMO) is one of the four quadriceps muscles in the front of your upper thigh. 25 Ryan JB, Wheeler JH, Hopkinson WJ, Arciero RA, Kolakowski KR. The gemelli muscles are two small muscular fasciculi, accessories to the tendon of the internal obturator muscle which is received into a groove between them. Head of Department of Radiology, Clinical Training Centre, Faculty of Medicine, Universiti Teknologi MARA . Anterior RF myofascial injuries are difficult to diagnose with ultrasound and deep posterolateral injuries have a tendency to be re-injured and form seromas when players return to activity4. 2Department of Radiology, Stanford University, Stanford,CA, USA. Patients complain of localized pain and swelling and limited range of motion. The distal rectus femoris musculotendinous junction is located at this posterior tendon, not at the distal end of the deep, central tendon, which is a common misconception. It should also be kept in mind that juxtacortical osteosarcoma is unusual adjacent to the AIIS. During these three days, avoid working out any lower extremity to allow the vastus medialis . The pattern of edema surrounding the deep tendon has been compared to a bulls eye17 (Figure 17) and a similar pattern may be seen if gadolinium-enhanced images are obtained, due to enhancement of post-injury vascular and inflammatory tissue. It is a direct antagonist to the hamstrings and it is innervated by the posterior division of the femoral nerve (L2, L3, L4). Patients with signs and symptoms of quadriceps or hamstring injury may have negative MRI examinations (3 of 25 in this study)20,27 This may be due to injury of insufficient size or severity to result in imaging findings, MRI performed before edema/inflammatory response developed or spine or trunk injury with referred pain. Ice and compression are also applied at this time25. The vastus medialis muscle wastes early and quickly when there is pain and even more so when there is swelling as well. Comparison radiographs of the contralateral hip may aid in distinction between an open apophysis and an avulsion fracture. West Point update. At 19.5% of the overall bus fleet, Kaohsiung City won first place in the MOTC demonstration electric bus subsidy program. Br J Sports Med 2001;35:435-440. Injuries of the quadriceps mechanism. Injuries of the origin of the direct and indirect heads of the rectus femoris have been infrequently reported. Intramuscular hematoma is more common with contusion and causes pain and loss of range of motion (Figure 23). Radiology. The rectus femoris acts to extend the lower leg at the knee and flex the thigh at the hip. 5. Orthopedics 2010;33:40-46. Of the four muscles that comprise this group, the rectus femoris is the most commonly strained and also has the most complex anatomy. This is a shame, because it plays a critical role in keeping your knees healthy and boosting your performance in the squat and deadlift. In another study, 6 patients who presented with an anterior thigh mass could not remember a traumatic event. Powered by, Vastus medialis obliquus (VMO) tendinous tear-MRI. He has a keen interest in Web 2.0 technologies and in maintaining his famous radiology blog, which has been featured in multiple international journals. In one study, surgery was performed on three patients and revealed intramuscular fibrous scar, 1-3 cm wide and 15-23 cm long34. Remember that your rate of healing won't be the same as someone else's. Folia Morphol (Warsz) 2006;65:377-380. Next, move your hand a couple of inches up and to the inner part of your thigh. Coronal MR-arthrogram T1-weighted images, from posterior(superior) to anterior(inferior), demonstrate the origin of the indirect head (short arrow) from the acetabulum and joint capsule (superior and middle images). There is a tear of the vastus intermedius muscle centrally, predominately involving the anterior fibers at the myotendinous junction. 1. Churchill Livingstone. The vastus medialis can be injured when engaging in a variety of daily and athletic activities. Swelling is common after a knee injury or surgery and can inhibit the function of your quad and vastus medialis. 6 Orchard JW. On MRI, an acute hematoma, up to 2-3 days old, is isointense to muscle on T1 images and hypointense on T2 images. Intrinsic and extrinsic risk factors for muscle strains in Australian football. An axial T2-weighted image (19c), distal to the retracted muscle, reveals centrally located fluid/hematoma (arrowheads) surrounded by edematous outer muscle. Cross-sectional area of the vastus medialis oblique The average cross-sectional area of the VMO was 3.79 1.03 cm2in the patient group and 4.41 1.57 cm2in the control group. (11c) Distal shaft level. This sequence of injury does not apply to AIIS avulsion, as demonstrated by their above-noted 14 year old patient and other reports of AIIS avulsion. Point #1: In the bottom 15 degrees of the squat. In athletics, contusion most often involves the quadriceps, and the vastus intermedius is the most commonly affected muscle8. A radiologic prespective: magnetic resonance imaging of muscle. If the central portion of the mass is biopsied, it frequently demonstrates histologic features suggestive of a reactive or aggressive process and an inexperienced pathologist may mistake it for osteosarcoma. 19 Palmer WE, Kuong SJ, Elmadbouh HM. You can use Radiopaedia cases in a variety of ways to help you learn and teach. Axial T2-weighted image (19a): a large amount of fluid (arrowheads) separates the inner (asterisk) and outer rectus femoris muscles with intramuscular edema. Scientific presentation SSA 14-08. 2 Tubbs RS, Stetler W Jr, Savage AJ, Shoja MM, Shakeri AB, Loukas M et al. The most proximal rectus femoris tendons may be injured at or just distal to their origin. Injury to the muscle can cause weakness, change how your knee moves, or affect your ability to walk and run. In young, athletic patients, partial or complete tears may occur with strong deceleration while running31. This means squatting low enough that your hamstrings touch your calves in the bottom position. The extent of the tear and whether it requires surgery will influence the length of recovery. KOA-related . The vastus medialis (VM) originates from the lower part of the intertrochanteric line, medial lip of the linea aspera and upper third of the medial supracondylar line, and has distal attachments via an aponeurosis to the quadriceps tendon and the medial border of the patella 1). 13 Deehan DJ, Beattie TF, Knight D, Jongschaap H. Avulsion fracture of the straight and reflected heads of rectus femoris. When patients with AIIS avulsion present in the subacute or chronic phase, radiographs may demonstrate an area of heterotopic ossification at the site of injury that may be misinterpreted as osteosarcoma or other bone-forming neoplasm11,12. Deep, central musculotendinous strains required 27 days for recovery, versus 9 days for peripheral strains. On the sagittal T2-weighted fat-suppressed image through the mid-thigh, the inner rectus femoris muscle is proximally retracted by 1 cm and fluid (arrows) separates it anteriorly, distally and posteriorly from the outer muscle. He has also been an invited faculty member at various conferences, including Teleradiology in IRIA 2008 and 2011, Hospital Build Middle East, Congress of the Brain Tumor Radiology in Neuro-oncology Society. Distal rectus femoris tendon (arrow). Mark D. Miller, Stephen R. Thompson. Verywell Health's content is for informational and educational purposes only. Depending on the reason the muscle is impaired, there are different options for treatment. Sagittal proton density fat suppressed image: complete tear of the rectus femoris portion of the quadriceps tendon with 1.5 cm proximal retraction (arrow). This injury occurs due to the trauma. 3D graphic demonstrating the lateral perspective of the origin of the rectus femoris. 8 Boutin RD. Here is my attempt to explain the charm of this branch. Other arrangements are also observed, such as, a two-layered or four-layered structure or, rarely, as a single band of tendon, depending on separation or convergence of the tendons28. The rectus femoris muscle is the most anterior and superficial of the quadriceps muscle group. A gadolinium-enhanced MRI may be useful to confirm a hematoma if the mass shows rim enhancement without any enhancing, solid components. What is your diagnosis? The quadriceps muscle group is vital for athletes who participate in sports that require running, jumping and kicking. History of trauma (2 months before examination). Sagittal T1-weighted image (left) and sagittal proton density fat-suppressed image (right) reveal an enlarged, edematous quadriceps fat pad (arrow), suggestive of fat pad impingement. 2022 Dotdash Media, Inc. All rights reserved. There is also an assoicated hematoma, with edema collected behind rectus femoris muscle and througout the mid vastus intermedius, with minimal edema in the overlying rectus femoris muscle. Ten fresh-frozen cadaver knees without deformity and three retrieved knees were used to dissect nerve branches along the femoral nerve distally until they ended in muscle. Avulsion injuries of the pelvis. MRI is useful for diagnosis of subtle tears (Figure 14) and to determine the extent of retraction of complete tears (Figure 15). Extend your knee as far as you can and tighten your quadriceps. Fluid may track several cm distally along the deep surface of the anterior fascia. It gives rise to a bipennate muscle which is surrounded by the unipennate muscle (Figures 10,11). Suggest you go back to surgeon and be sure there is not underlying infection or pathol. You can repeat this one to two times every two hours for the first two to three days, according to the University of Wisconsin-Madison's School of Public Health and Medicine (UW). Once the nerve is free, you can use strengthening exercises to regain normal knee function. Why do best medical graduates choose Radiology? 1) Vastus lateralis muscle: The vastus lateralis is the largest and most powerful muscle that makes up the quadricep. The sagittal distance between the two slices was The vastus medialis oblique (VMO) of the quads extends the knee. Pseudotumor may also be due to formation of a hematoma or seroma/pseudocyst. In two patients reported by Oullette et al, a partial tear of the indirect head was seen on MR-arthrography, suggesting an associated tear of the superior joint capsule (Figure 16). Rupture usually occurs in patients older than 40 with a peak incidence in the 5th through 7th decades. Am J Sports Med 1995;23:493-499. IMF and muscle architecture were calculated from rectus femoris (RF), vastus intermedius (VIM), vastus lateralis (VL), vastus medialis (VM), biceps femoris (BF), semitendinosus (ST) and semimembranosus (SM) using B-mode ultrasonography. Vastus medalis works with the other quadriceps to straighten the knee. Vastus Medialis - Often referred to as the 'teardrop,' the Vastus Medialis is located on the quadriceps' inner side and ends near your patella (kneecap). Precursor to degloving injury? 35 Temple HT, Kuklo TR, Sweet DE, Gibbons CLMH, Murphey MD. Traumatic fibrosis of the rectus femoris muscle. Surg J. The rectus femoris is vulnerable to injury because it crosses two joints, has a high proportion of type II, fast twitch muscle fibers and because, in an athletic kicking motion (soccer, football, martial arts), it undergoes forceful eccentric contraction while passively stretched at the onset of the forward swing phase5. Continuity of the quadriceps and patellar tendons is accomplished by distal extension of fibers of the rectus femoris tendon to insert into the bone at the anterior surface of the patella. (11a) Proximal-to-mid-shaft level. By correlating findings on MRI with clinical data, MRI contributes to treatment planning and can be used to predict the recovery interval. But some anatomist do not accept VMO as real muscle. S = sartorius muscle. The vastus medialis oblique (VMO) muscle is a distal component of the vastus medialis whose fibers have a more oblique course, blending distally with the medial patellofemoral ligament, in order to stabilize patellar tracking. Read our, How Hip Weakness Contributes to Knee Pain, Vastus Inhibition After Injury or Surgery, Physical Therapy Exercises After a Tibial Plateau Fracture, An Overview of Patellofemoral Stress Syndrome, 6 Things That Can Make Your Knee Give Out, The Anatomy of the Vastus Lateralis Muscle, Quadriceps-Strengthening Exercises That Minimize Knee Joint Stress, Exercise Program for Patellofemoral Syndrome, heel slides, quad sets, and straight leg raises, neuromuscular electrical stimulation (NMES), Synovial Plica Syndrome of the Knee: A Commonly Overlooked Cause of Anterior Knee Pain, Femoral Nerve Palsy with Patella Fracture, Alterations in in vivo knee joint kinematics following a femoral nerve branch block of the vastus medialis: Implications for patellofemoral pain syndrome, Neuromuscular electric stimulation in patellofemoral dysfunction: literature review, Anatomy, Bony Pelvis and Lower Limb, Anterior Thigh Muscles. 3D graphic of the quadriceps muscle group with the rectus femoris muscle partially resected demonstrates the 4 components: rectus femoris (RF),vastus medialis (VM), vastus intermedius (VI), vastus lateralis (VL). 3. At the distal thigh, the tendons of these muscles merge to form the quadriceps tendon. Am J Sports Med 1978;6:185-193. If you injure your vastus medialis, you should apply ice to the injured area and lightly stretch the muscle for 20 minutes. The proximal rectus femoris musculotendinous junction is distal to the conjoined tendon and refers to the anteriorly located direct head and its unipennate muscle and the indirect head (also referred to as the deep or central tendon) and its bipennate muscle, the latter of which extends to the junction of the middle and distal 2/3 of the RF muscle. In the first several weeks, radiographs and CT are inconclusive as only non-specific mineralization is present. AJR 2004;182:1383-1387. On MRI, muscle contusion may have an appearance similar to a muscle strain, although a contusion is not centered on a musculotendinous junction, may cross fascial planes and may enlarge the muscle. The distal tendon has a flat configuration and merges with the vastus tendons to form the quadriceps tendon. Electrical activity of the vastus medialis oblique, the vastus lateralis, the vastus intermedius, and the vastus medialis longus muscles was measured in eight uninjured subjects. In other muscles with conventional anatomy, epimysial tear and perifascial fluid usually occur with a grade 2 strain but this is less common with injury to the deep RF musculotendinous junction. 3 Bennett W, Doherty H, Hollisery M, et al. The other components of the quadriceps mechanism are the vastus medialis (with its distal, oblique component), vastus intermedius and vastus lateralis. There is a tear of the vastus intermedius muscle centrally, predominately involving the anterior fibers at the myotendinous junction. In the case illustrated here, the vastus medialis and vastus lateralis flaps have been sown together and the medial head of the gastrocnemius muscle has been used to provide distal anchorage of the quadriceps flaps and to add soft tissue coverage over bone deficiency in the tibia. The Vastus medialis muscle is also called the vastus medialis obliquus and is one of the four muscles which make up the quadriceps muscle. Gray's Anatomy for Students: With STUDENT CONSULT Online Access, 3e. The vastus medialis works with the other quadriceps muscles to help you extend your knee joint. Separation of the prepatellar quadriceps continuation from the anterior patellar surface has been observed on MRI in patients with anterior knee pain (Figure 26). Clin Orthop Relat Res 2009;467:3297-3306. If your femoral nerve becomes pinched by arthritis or a bulging disc in your back, it can cause vastus medialis weakness and limit your ability to walk..
