A distal biceps tendon tear is an uncommon injury. There is some cartilage thinning, but not a defect. The flexor carpi radialis, palmaris longus, and flexor carpi ulnaris form the common flexor tendon. 47, No. MR imaging is the most widely used modality, although US also may be performed. Brantigan and Voshell  found evidence of the medial collateral ligament (MCL) bursa in 52 (91%) of 57 dissected knees.Despite this high prevalence, to our knowledge, only one article in the radiological literature refers to the MCL bursa . Typically, the extensor carpi radialis brevis is the component that is involved. The mechanism of injury to the UCL is usually chronic tensile forces, which create microtears. On the axial image we nicely see the anterior bundle is o.k. These are images of a 20 year old baseball pitcher. The lateral epicondyle is also the site of attachment for the extensor digiti minimi and the supinator, which merge with the ECRB, extensor digitorum communis, and extensor carpi ulnaris to form the common extensor tendon (Fig 1). ANT = anterior.

Soft-tissue mass: ganglion, lipoma, osteochondroma, synovitis secondary to rheumatoid arthritis, infection (eg, tuberculosis), and hemorrhage. Scroll through the images. There is only fluid. Coronal proton density–weighted fat-saturated MR image obtained in a 30-year-old woman shows a normal appearance of the common extensor tendon at the site of its attachment to the lateral epicondyle (arrow). 5, Revue de Chirurgie Orthopédique et Traumatologique, Vol. Lateral epicondylitis is also known as the tennis elbow, although in 95% of cases it is seen in non-tennis players. In addition, the patient had numbness in both forearms when he sleeps in the flexed position of the elbow. Because of the close proximity of the nerve and ligament, aggressive tendon débridement is not performed for medial epicondylitis (9). Degenerated peritendinous tissue in the interval between the pronator teres and the flexor carpi radialis is removed with aggressive débridement. The anterior forearm contains several muscles that are involved with flexing the digits of the hand, and flexing and pronating the wrist. Here the common flexor tendon is involved. Medial epicondylitis, also called golfer's elbow, was first described in 1882 by Henry J Morris. Thereby tendon degeneration appears instead of repair. If these measures fail to bring relief, nighttime use of a splint and one or more local corticosteroid injections may be necessary (7,9). 23, 12 October 2017 | European Radiology, Vol. It is seen in the lateral trochlea like in this case due to repetitive hyperextension in an area with tenuous blood supply. J.S.N. Cubital tunnel syndrome is a common peripheral neuropathy. Coronal STIR MR image obtained in a 40-year-old woman depicts intramuscular edema as a focus of high signal intensity within the extensor carpi radialis longus (arrow), a finding consistent with muscular strain and associated with lateral epicondylitis. Plane selection is important when evaluating the common flexor and extensor tendons and requires proper training of MR imaging technologists. Notice that it is a young patient, because the physis is still open. Here are the ultrasound images of a 73 year old male who experienced a sudden pain and a tearing sensation when lifting a box. Elbow synovial fold syndrome is an uncommon entity that is often confused with lateral epicondylitis. Then holes are drilled in the capitellum and the defects are filled with the autologous bone and cartilage. Remember that the biceps tendon does not have a tendon sheaht, so tenosynovitis is not a possibility. The mass is very heterogeneous as is the enhancement.
