The concavity at the posterolateral margin of the humeral head should not be mistaken for a Hill Sachs, because this is the normal contour at this level. 2. MRI is the preferred method for evaluating internal derangement of the shoulder. Imaging interpretation of the postoperative shoulder is a challenging and difficult task for both the radiologist and the orthopedic surgeon. (2014) World journal of radiology. {"url":"/signup-modal-props.json?lang=us\u0026email="}. The abduction and external rotation of the arm releases tension on the cuff relative to the normal coronal view obtained with the arm in adduction. Study the cartiage. The incidence in the general population is thought to be 3-5%. The rotator interval is assessed with respect to biceps pulley injury and in cases of suspected adhesive capsulitis. The bony structures of the shoulder, the pictured proximal humerus, the pictured scapula with the glenoid, coracoid process as well as the acromion and the distal clavicle are assessed: Assessment of the acromioclavicular joint,  including acromial shape, downslope, variant anatomy. This approach is an example of how to create a radiological report of an MRI shoulder with coverage of the most common anatomical sites of possible pathology, within the shoulder. subchondral cysts and osteophytes (arrow). The diagnosis is commonly made through a combination of clinical history and physical examination findings, but early signs of adhesive capsulitis can be nonspecific and overlap with other causes of shoulder stiffness.1,2Recognizing the characteristic MRI fi… An os acromiale must be mentioned in the report, because in patients who are considered for subacromial decompression, The os acromiale may cause impingement because if it is unstable, it may be pulled inferiorly during abduction by the deltoid, which attaches here. Detection of partial-thickness supraspinatus tendon tears: is a single direct MR arthrography series in ABER position as accurate as conventional MR arthrography? Sometimes at this level labral tears at the 3-6 o'clock position can be visualized. These normal variants are all located in the 11-3 o'clock position.

Structured reporting of MRI of the shoulder - improvement of report quality?. Exercising the shoulder joint for about 10 minutes after contrast material injection and using fat-saturated MR imaging sequences increases the sensitivity for detection of labral tears . Symptoms are usually comparatively mild, despite rapid and marked progression of radiographic features. The MRI allows accurate assessment of any pathologic changes of the structures of the shoulder, including the glenoid labrum, the humeral head, the articular cartilage, and the rotator cuff. The coracoacromial arch provides a safeguard for the shoulder, limiting superior migration of the humeral head. Failure of one of the acromial ossification centers to fuse will result in an os acromiale. Radiology. Unable to process the form. Look for supraspinatus-impingement by AC-joint spurs or a thickened coracoacromial ligament. MRI of the shoulder, T1, Coronal view. Notice smooth undersurface of infraspinatus tendon and normal anterior labrum. Consecutive sagittal fat-saturated T2-weighted MR images (repetition time msec/echo time msec = 3000/60) (a obtained medial to b) show overlap between the distal supraspinatus tendon (SST) (green) and the distal infraspinatus tendon (IST) (yellow). The tendon of the subscapularis muscle attaches both to the lesser tubercle aswell as to the greater tubercle giving support to the long head A shoulder MRI helps your doctor diagnose potential problems found in other imaging tests, such as X-rays. Hill Sachs lesions are only seen at the level of the coracoid. Labral tears The small size of the glenoid fossa and the relative laxity of the joint capsule renders the joint relatively unstable and prone to subluxation and dislocation. MRI Series – Shoulder MRI of the Shoulder. Morag Y, Jacobson JA, Miller B, De Maeseneer M, Girish G, Jamadar D. MR imaging of rotator cuff injury: what the clinician needs to know. They all attach to the greater tuberosity. Usually it is an incidental finding and regarded as a normal variant. Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. The anterior labrum is absent in the 1-3 o'clock position and there is a thickened middle GHL. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. This chapter is an outline of the basic principles of magnetic resonance imaging (MRI) of the shoulder with an emphasis on the clinical issues related to the imaging findings of shoulder pathology. $350 & up. Notice that the supraspinatus tendon is parallel to the axis of the muscle. Without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. RadiologyInfo.org is the public information resource developed by health care professionals in collaboration with patients. A Buford complex is a congenital labral variant. nor be effaced against the humeral head, and intra-articular contrast can enhance visualization of the tear (3). Adhesive capsulitis typically affects women in their 5th to 6th decades, although patients with co-morbidities such as diabetes mellitusmay develop the condition at earlier ages. It also helps your doctor diagnose unexplained pain in … Overlap between the distal supraspinatus and infraspinatus tendons. The role of diagnostic imaging in the evaluation of shoulder pain is to guide clinical management. 6, Scapula. At Hoag, the expertise, technological resources, accountability and connectivity of our radiology team is what sets us apart from other imaging centers. It is present in approximately 1.5% of individuals. (2017) European radiology. superior labral anterior-posterior (SLAP) tears. Notice the fibers of the inferior GHL. If surgical treatment is decided, imaging can be used further to plan the surgical approach whether it be open or arthroscopic. With the inclusion of our CT and X-ray facilities, RESTORE Imaging can provide comprehensive diagnostic, minimally invasive radiographic and digital radiology … Notice coracoclavicular ligament and short head of the biceps. Study the attachment of the IGHL at the humerus. Internal impingement, also known as posterosuperior impingement in prior orthopedics and radiology literature, is a condition that occurs in athletes in which the shoulder is put in extreme abduction and external rotation during overhead movements. Biomechanical comparison of effects of supraspinatus tendon detachments, tendon defects, and muscle retractions. The ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff. Normal shoulder MRI for reference. The radiologic technique for shoulder imaging and basic shoulder anatomy are first discussed. SHOULDER MRI EXAM. The coracoacromial arch is composed of (from anterior to posterior) the coracoid process, coracoacromial ligament, and the acromion process. Stanford bone tumor ddx | ISS/SSR MSK lectures | OCAD MSK cases Stanford MSK MRI Atlas has served over 1,000,000 pages to users in over 100 countries. The axial MR-images show an os acromiale with degenerative changes, i.e. On these axial images a Buford complex can be identified. Study the superior biceps-labrum complex and look for sublabral recess or SLAP-tear. Tears of the supraspinatus tendon are best seen on coronal oblique and ABER-series. 1, Pectoralis major muscle. 4, Deltoid muscle. On MR an os acromiale is best seen on superior axial images.

Indirect MR arthrography demonstrates good accuracy in the diagnosis of SLAP lesions, with arthroscopy used as the standard of reference ( 26 ). ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Notice the smooth borders unlike the margins of a SLAP-tear. In the presence of a rotator cuff tear, imaging can determine whether the tear is full thickness or partial thickness and thus help the clinician decide between operative or nonoperative treatment (20). Figure 1b. https://radiologyassistant.nl/musculoskeletal/shoulder/mri-anatomy The glenohumeral joint has the following supporting structures: Anterior graphic of the shoulder. Hoag Breast and Imaging Center 16305 Sand Canyon Ave, Ste 150 & 160 Irvine, CA 92618 Overlap between the distal supraspinatus and infraspinatus tendons. The insertion has a variable range. Notice MGHL, which has an oblique course through the joint and study the relation to the subscapularis tendon. Look for rim-rent tears of the supraspinatus tendon at the insertion of the anterior fibers. In part II we will discuss shoulder instability. There are many labral variants.
