In atraumatic posterior instability there is no history of major trauma, however, there is almost always an element of repetitive microtrauma causing labral pathology and posterior capsular stretching. In general, a therapy program focuses first on flexibility. If the injury is a minor Bankart tear with a dislocation, the physician (or even a team coach or patient themselves) can usually pop the shoulder back into place a process called reduction and then follow up with physical therapy to strengthen the muscles. Journal of Bone and Joint Surgery 74A:53-66, 1992. Palmer W, Bancroft L, Bonar F et al. In more advanced cases of glenoid dysplasia, hypertrophic changes of the labrum and hyaline cartilage are pronounced. 35-year-old man with shoulder pain and decreased range of motion. Approximately half of the posterior shoulder dislocations go undiagnosed on initial presentation, because of a low level of clinical suspicion and insufficient imaging. Such lesions are generally found in patients with atraumatic posterior instability. Below: an MRI arthrogram showing injection of contrast into the shoulder joint. The shoulder almost always dislocates to anterior and inferior, because motion to superior is limited by the acromion, coracoid process and rotator cuff (figure). Evaluation and management of posterior shoulder instability. Provencher MT, Dewing CB, Bell SJ, McCormick F, Solomon DJ, Rooney TB, Stanley M.An analysis of the rotator interval in patients with anterior, posterior, and multidirectional shoulder instability. Labral repair or resection is performed. 9 Tung GA, Hou DD. True dysplasia should be visible on at least two axials slices cephalad to the most inferior slice of the glenoid (Fig. As a result, in cases of posterior shoulder instability, particularly dislocation, capsular tears are frequently identified on MR imaging.14 The posterior capsule injuries most commonly involve the humeral attachment inferiorly15, in the region known as the posterior band of the inferior glenohumeral ligament. Labral Tear( ) 93%, Labral detachment( ) 46%. (Find an HSS doctorwho diagnoses and treats shoulder labral tears.). Sectioning of the rotator interval capsule has been shown to increase posterior and inferior translation of the humeral head.3.

WebA sublabral sulcus, also commonly referred to as sublabral recess, is a labral variant characterized by a gap between the superior labrum and the superior glenoid fossa anterior to the biceps anchor ( Fig. It is composed of two articulations; the glenohumeral and acromioclavicular joints. Regardless of which type of surgery is performed, almost all athletes are advised to wear a sling for the first four weeks after surgery to protect the shoulder as it heals. The major restraints to posterior instability include the posterior capsule and glenohumeral ligaments, the rotator interval, the labrum, the glenoid, and the musculature of the rotator cuff and shoulder. Patients with periosteal sleeve avulsions, such as the POLPSA, are more likely to be symptomatic.9. Diagnosing a labrum tear involves a physical examination and most likely an 6,11,16,17 In the current study, 244 of the shoulders that underwent shoulder MRI demonstrated a posterior glenoid labral tear MRI() . Specific exercises will restore movement and strengthen your shoulder. The image on the right is rotated 90? Illustration of the shoulder anatomy and labrum. The surgical technique most commonly used for repairing a SLAP injury is arthroscopy. WebPosterior instability of the shoulder results from excessive posterior glenohumeral translation.

There is a detachment of the anteroinferior labrum (3-6 o'clock) with complete tearing of the anterior scapular periosteum. There are many labral variants that may simulate a labral tear. At first, the repair needs to be protected while the labrum heals. Most patients do not experience complications from shoulder arthroscopy.

Webwhich situation is a security risk indeed quizlet; ABOUT US. The subscapularis muscle has been identified as the most important muscle in resisting posterior subluxation of the humerus.5 Asynchrony of scapulothoracic and glenohumeral muscle contraction may compromise the stability of the glenohumeral joint. On the AP-view the head looks strange due to the internal rotation. Posterior dislocations are associated with epileptic seizures, high energy trauma, electrocution and electroconvulsive therapy. First scroll through the images and try to find out what is going on. Posterior dislocations are uncommon and easily missed, because there is less displacement compared to the anterior dislocation. On MR a Hill-Sachs defect is seen at or above the level of the coracoid process. On MR-arthrography it may be difficult to depict the osseus fragment. Due to the ABER-position the anterior band of the inferior GHL creates tension on the anteroinferior labrum and contrast fills the tear. MR Arthrography of the Posterior Labrocapsular Complex: Relationship with Glenohumeral Joint Alignment and Clinical Posterior Instability. Posterior dislocation-fracture. Comparison with the contralateral shoulder is critical in identifying significant shoulder subluxation versus normal laxity. The shoulder joint is a joint that connects the upper limb to the axial skeleton. Rotator cuff tears in the context of posterior shoulder instability or dislocation were once thought to be rare. MRI is not uncommonly the key to the diagnosis as patients may present with vague clinical findings that are not prospectively diagnosed, in part because of the relatively less common incidence and awareness of this entity. The Bennett lesion (Fig. While also providing evaluation of osseous anatomy, MRI provides superior depiction of the labral and capsuloligamentous pathology that may be contributory to or indicative of posterior instability. Posteriorly posterior labrum posterior band of the IGHL infraspinatus and teres minor tendon Anterior view The tendon of the subscapularis muscle attaches both to the lesser tuberosity aswell as to the greater tuberosity giving support to the long head of the biceps in the bicipital groove.

The glenoid labrum, an important static stabilizer of the shoulder joint, has several normal labral variants that can be difficult to discriminate from labral tears and is subject to specific pathologic lesions (anteroinferior, posteroinferior, and superior labral anteroposterior lesions) with characteristic imaging features. The glenoid labrum, an important static stabilizer of the shoulder joint, has several normal labral variants that can be difficult to discriminate from labral tears and is subject to specific pathologic lesions (anteroinferior, posteroinferior, and superior labral anteroposterior lesions) with characteristic imaging features. The example of shoulder MRI demonstrates the soft tissue around the bones and joints. Radiographics. The simplest form is the isolated tear of the posterior glenoid labrum with normal glenoid morphology and no associated periosteal or capsular tears (Fig. It is above or at the level of the coracoid in the first 18 mm of the proximal humeral head. Bankart tears typically occur in younger patients who have dislocated their shoulder. These are usually minor and treatable.

The MR-images are of a patient who had undergone both an anterior aswell as a posterior dislocation. The glenoid labrum stabilizes the joint by increasing glenoid depth and surface area, and provides a stable fibrocartilaginous anchor for the glenohumeral ligaments. Superior labral anterior posterior (SLAP)tears are injuries of the glenoid labrum,and can often be confused with a sublabral sulcus on MRI.

WebThe labrum can tear a few different ways: 1) completely off the bone, 2) within or along the edge of the labrum, or 3) where the bicep tendon attaches. 35-year-old man with shoulder pain and decreased range of motion. On MR arthrography it is customary to combine T1, T1 FS and T2 4. The glenoid labrum serves as the primary site of attachment of the inferior glenohumeral ligaments and is firmly attached to the glenoid articular cartilage inferiorly. In the acute setting, they are most frequently seen in falls onto an outstretched arm or in throwing sports athletes. Diagnosing a labrum tear involves a physical examination and most likely an 10 Lamar DS, Williams GR, Iannotti JP, Ramsey ML. 37-year-old man with shoulder injury and posterior labral tear.

St. Louis, MO: Mosby Year Book; p325-9, 1990. The ligaments also help prevent the shoulder from dislocating. The biggest advantage of MR arthrography comes from the joint distension, which can help spot otherwise occult tears. The approach to surgery is dependent upon the type of injuries sustained by the patient, and the developmental or acquired alterations in anatomy that may be present.
