This MRI web clinic will describe MR imaging of quadriceps injuries, with emphasis on the rectus femoris (RF), and will review the prognostic significance of MRI findings as they relate to the time required for recovery and return to athletic activity.

Aug 16, 2024 · The rectus femoris muscle is one of four quadriceps muscles in the anterior compartment of the thigh. It is distinct from the other quadriceps muscles (vastus medialis, vastus intermedius, vastus lateralis) in that it crosses both the hip and knee joints 1.

Nov 15, 2024 · The rectus femoris muscle is most frequently affected in a quadriceps injury and the most common pattern are muscle strains 1-3. Risk factors. Sports and activities involving a great amount of kicking, jumping and running are considered risk factors for developing a rectus femoris muscle injury and include 1-3: football/soccer. American ...

Axial and coronal MR images are optimal for visualizing the direct and indirect heads, the conjoined tendon, and the deep musculotendinous junction of the proximal rectus femoris. Tears of the deep musculotendinous junction are longitudinal, in-volving a long segment of the muscle.

Jan 22, 2014 · The reports of the MRI examinations were reviewed by one of two musculoskeletal radiologists (10 and 15 years of experience in musculoskeletal MRI) to determine whether the injuries described involved the intramuscular bipennate portion of the rectus femoris muscle.

Mar 1, 2008 · Axial and coronal MR images are optimal for visualizing the direct and indirect heads, the conjoined tendon, and the deep musculotendinous junction of the proximal rectus femoris. Tears of the deep musculotendinous junction are …

MR imaging is useful for confirming the diagnosis of rectus femoris tendon avulsion, grading the tear, and determining the extent of retraction in grade 3 tears. In chronic cases, MR imaging is also useful for assessing the extent of tendon fibrosis and for presurgical planning of scar, hematoma, or pseudocyst resection.

Feb 16, 2011 · The rectus femoris has somewhat complex anatomy that can be elegantly demonstrated with MR imaging . Proximally, there are two origins to the rectus femoris which consist of the direct and indirect (reflected) tendons or heads . The direct tendon arises from the anterior inferior iliac spine (AIIS) and the indirect tendon arises from the later ...

Jul 5, 2024 · Imaging and in particular ultrasound and MRI can provide information regarding the extent, type and prognosis of the muscle injury 2. ... which can nicely depict the proximal rectus femoris tendons, the rectus femoris muscle and the vastus muscles. The quadriceps tendon can be best visualized when the knee is flexed 7. CT.

Oct 1, 2009 · Most at risk are the hamstrings, rectus femoris and medial gastrocnemius. Strain involving the upper extremity is slightly less common and then usually involves the biceps brachii. The hallmark of strain is a lot of edema around the myotendinous juntion because that is where the tearing takes place.
