This is arthrosis secondary to chronic instability due to the chronic partial tearing. UCL repair is done by placing tunnels in the medial epicondyle. It is seen in the lateral trochlea like in this case due to repetitive hyperextension in an area with tenuous blood supply. There is also some joint effusion in the talocalcaneal joint. In B there is edema and thickening of the posterior syndesmosis, which is an acute grade 2 injury. This sign presents as a fine linear band of high signal intensity which is the result of a small avulsion of cortical bone in a grade 3 full thickness tear.

What puts us among the best? On the axial image, the edema is localised around the insertion site of the posterior syndesmosis. So this was not a cystic mass. The problem is that they may mimic infection or tumor. In any shoulder examination we should look for signs of impingement like a narrowed subacromial space, abnormal shape of the aromion or osteoarthrosis. ImagesIllustration and coronal T1 fat-suppressed MR arthrogram. Notice that there is also a grade 2 tear of the ATFL. The rotator cuff is composed of the tendons of the subscapularis, supraspinatus, infraspinatus and teres minor, that attach to the proximal humerus.The main function of the rotator cuff is to stabilize and center the humeral head in the glenoid cavity during movements of the arm by compressing the humeral head against the glenoid.The rotator cuff as the name suggests also plays a major role in the internal and external rotation of the arm. Questions regarding prerequisite requirements will ONLY be answered via email. Pieces of cartilage and bone are taken out of some other non-weight bearing bone and tranferrred to the capitellum. In most clinical scenarios this refers to a radiograph of the glenohumeral joint. They are called rice bodies because when you open up the joint, they just look like rice. On the sagittal image the tendon is thickened, but distally the tendon is lost. A tear can also occur in a fall on the outstretched hand.

Maybe there only was some tendinosis or tendinitis. MR is the best imaging modality to examen patients with shoulder pain and instability. Partial thickness tears are best visualized on coronal PD and T2WI with and without fat suppression.MR arthrography is very sensitive for detection of even small PTT, but only on the articular surface.The ABER position allows assessment of both the vertical and interstitial component. In those cases you may consider a CT-scan which can be more sensitive. This is the most commonly injured ligament of the ankle and it is also the first to be injured on the lateral side.
