The anterior bundle extends from the inferior aspect of the medial epicondyle and inserts on the sublime tubercle (medial aspect of the coronoid process) and provides the primary constraint against valgus stress (7,11,22). Epicondylitis was initially believed to originate from an inflammatory process involving the radial humeral bursa, synovium, periosteum, and annular ligament (9). Here we see images of a patient after repair who did not do so well. Given its location in the medial elbow, the ulnar nerve should be evaluated in all patients with medial elbow pain. Always make sure that your axial scan goes all the way to the tuberosity, because is you stop too early, like in this case, then you will only see a thickened tendon and some fluid, but you are not sure about a possible tear. Longitudinal US image obtained in a 49-year-old woman depicts the common flexor myotendinous junction (*) and tendon origin at the medial epicondyle (arrow).Figure 29Download as PowerPointOpen in Image Click on the image (or right click) to open the source website in a new browser window. The RCL, which is located immediately anterior to the LUCL, also originates from the lateral epicondyle (Fig 5). If you cannot make a specific diagnosis, just call the mass indeterminate an do a biopsy, because in many cases you cannot tell the diagnosis. 4, No. [] This condition is an overuse syndrome that is characterized by pain at the flexor-pronator tendinous origin and is seen in sports activities with repetitive valgus stress, flexion, and pronation, such as occurs in golf, baseball, tennis, fencing, and swimming. Use the axis of the epicondyles on a axial localizer to plan the coronal scan. Patients with medial epicondylitis typically present with medial elbow pain, which often develops insidiously (except in acute trauma). As you go more posteriorly you will see the LUCL - the lateral ulnar collateral ligament, which sweeps behind the radial head (white arrows). Figure 29 Normal medial elbow. Lateral epicondylitis occurs with a frequency seven to ten times that of medial epicondylitis. In addition to the mechanical forces that lead to excessive varus stress on the ECRB, its unique anatomic position against the lateral aspect of the capitellum places the tendon at risk for repeated undersurface abrasion during elbow extension (12). Notice the inhomogeneous enhancement on the MRI and prominent internal vascularity on the sagittal ultrasound image. Medial epicondylitis, or "golfer's elbow," is similar to the more common lateral epicondylitis ("tennis elbow") in many respects. In any synovial lined joint or bursa these rice bodies can be formed as a result of chronic inflammation with synovial hypertrophy. T1In every joint that is studied you should have at least one T1-sequence not only to look at the anatomy, but also as a back up for looking at the marrow. Table 1 Anatomy of the Muscles of the Lateral Compartment of the Elbow, Capsular injury as well as thickening and tearing of the lateral ulnar collateral ligament (LUCL) and radial collateral ligament (RCL) have been identified in association with severe lateral epicondylitis (14,15). On MR this is the most important structure. 24, No. Notice that the ulnar nerve (blue arrow) is next to these osteophytes and these patients may present with ulnar neuropathy. Then when you follow it proximally, you will notice that this was a subcutaneous transposition. Blog; PACS Case Studies; White Papers; Events; About. Axial images are obtained perpendicular to the long axis of the humerus at the elbow. Medial Plantar Proper Digital Neuropathy ... Stoller DW, ed. Again this was diagnosed as indeterminate. T1 is certainly used in MR-arthrography. He complains of intermittent elbow pain and popping. Clin Sports Med 1996;15:283–305. There is a complete tear, because if we follow the tendon all the way to the radial tuberosity, we can see that the tendon does not attach there (green arrow). On the upper left T1W-image there is high signal fat within the extensor muscles with loss of muscle bulk which indicates fatty atrophy. The chronic valgus overload can cause an osteochondral lesion on the lateral side of the elbow. Ulnar collateral ligament or UCL This is the counterpart of the lateral epicondylitis and also known as the golfer's elbow. Viewer Magnetic resonance imaging findings in patients with medial epicondylitis. Surgery is often performed if there is no clini-cal response after 3 to 6 months of conservative treatment. Longitudinal US view of the common extensor tendon origin in a 59-year-old man shows a small linear hypoechoic region at the origin of the ECRB (arrow), a finding indicative of a small partial-thickness tear. Epidemiology It is less common than lateral epicondylitis. Soft-tissue mass: ganglion, lipoma, osteochondroma, synovitis secondary to rheumatoid arthritis, infection (eg, tuberculosis), and hemorrhage. Medial epicondylitis, otherwise … There is partial tearing, but it is very extensive. Remember that the biceps tendon does not have a tendon sheaht, so tenosynovitis is not a possibility. Does effectiveness of exercise therapy and mobilisation techniques offer guidance for the treatment of lateral and medial epicondylitis? As with medial epicondylitis it typically occurs in the 4th to 5thdecades of life. On the axial image we nicely see the anterior bundle is o.k. Related Studies. It can be prominent and almost look like a meniscus. The extensor carpi radialis brevis (ECRB), extensor digitorum communis, and extensor carpi ulnaris form a strong, discrete, conjoined tendon that is attached at the anterior aspect of the lateral epicondyle and lateral supracondylar ridge, adjacent to the origins of the brachioradialis and extensor carpi radialis longus (11).
