posterior labral tear shoulder mri

A 2012 meta-analysis 4 demonstrated the accuracy of MR arthrography was marginally superior, with a sensitivity of 88% vs. 76% for conventional MR, and a specificity of 93% vs.87%. A sublabral foramen or sublabral hole is an unattached anterosuperior labrum at the 1-3 o'clock position. This ring of cartilage encompasses the outer rim of the glenoid to provide cushiony support around the head of the humerus. A SLAP tear may extend to the 1-3 o'clock position, but the attachment of the biceps tendon to the superior labrum should always be involved. It should always be possible to trace the middle GHL upwards to the glenoid rim and downwards to the humerus. 7-9). Mild glenoid hypoplasia results in a rounded contour of the posterior glenoid with normal or only mildly thickened posterior labral tissue. Fluid distends the joint and only lies along the inner margin of the joint capsule (arrowheads). At this level also look for Bankart lesions. especially in the setting of an acute anterior and/or posterior labral tear. 1985 Sep-Oct;13(5):337-41 The purpose of this study was to evaluate the accuracy of magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) in diagnosing superior labral anterior-posterior (SLAP) lesions. However labral tears may originate at the 3-6 o'clock position and subsequently extend superiorly. The following algorithm has been previously proposed 25. Indirect MR arthrography of the shoulder: use of abduction and external rotation to detect full- and partial-thickness tears of the supraspinatus tendon. 5,6,7 The classic MRI findings of internal impingement, as seen in this month's case, include partial articular surface tears at the posterior supraspinatus/anterior infraspinatus insertion, greater tuberosity bony changes, and tearing of the . MR arthrography had an accuracy of 69 %, sensitivity of 80 %, and a PPV of 29 %. Notice MGHL, which has an oblique course through the joint and study the relation to the subscapularis tendon. 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. difficulty performing normal shoulder . Diagnosis can be made clinically with positive posterior labral provocative tests and confirmed with MRI studies of the shoulder. Methods: Diagnosis . The site is secure. This top area is also where the biceps tendon attaches to the labrum. . The ball of the shoulder can dislocate toward the front of the shoulder (an anterior dislocation), or it can go out the back of the shoulder (called a posterior dislocation). Labral tears, such as a SLAP tear that cause a paralabral cyst, can occur due to trauma (dislocation), repetitive movement . X-rays also demonstrate evidence of glenoid dysplasia (increased retroversion and hypoplasia), arthritic changes, and posterior humeral head subluxation or decentering of the humeral head. What is Anterosuperior acetabular labrum? No Comments In part II we will discuss shoulder instability. Orlando Orthopaedic Center's Dr. Randy S. Schwartzberg, a board certified orthopaedic surgeon specializing in Sports Medicine, discusses what's involved with. Detection of partial-thickness supraspinatus tendon tears: is a single direct MR arthrography series in ABER position as accurate as conventional MR arthrography? Following a posterior subluxation event, a fat-suppressed T2-weighted coronal image in this 52 year-old male reveals focal edema and irregularity at the humeral attachment of the posterior band of the inferior glenohumeral ligament (arrow), compatible with a partial tear. Open Access J Sports Med. This procedure greatly enhances the diagnostic accuracy by allowing tears . posteriorly directed force with the arm in a flexed, internally rotated and adducted position, patients with increased glenoid retroversion (~17) were 6x more likely to experience posterior instability compared to those with less glenoid retroversion (~7), helps generate cavity-compression effect of glenohumeral joint, anchors posterior inferior glenohumeral ligament (PIGHL, vague, nonspecific posterior shoulder pain, worsens with provocative activities that apply a posteriorly directed force to the shoulder, ex: pushing heavy doors, bench press, push-ups, arm positioned with shoulder forward flexed 90 and adducted, apply posteriorly directed force to shoulder through humerus, positive if patient experiences sense of instability or pain, grasp the proximal humerus and apply a posteriorly directed force, assess distance of translation and patient response, grade 2 = over edge of glenoid but spontaneously relocates, grade 3 = over edge of glenoid, does not spontaneously relocate, arm positioned with shoulder abducted 90 and fully internally rotated, axially load humerus while adducting the arm across the body, arm positioned with shoulder abducted 90 and forward flexed 45, apply posteriorly and inferiorly directed force to shoulder through humerus, posterior shoulder dislocations may be missed on AP radiographs alone, arthroscopic and open techniques may be used, suture anchor repair and capsulorrhaphy results in fewer recurrences and revisions than non-anchored repairs, return to previous level of function in overhead throwing athletes not as reproducible as other athletes, failure risk increases if adduction and internal rotation are not avoided in the acute postoperative period, posterior branch of the axillary nerve is at risk during arthroscopic stabilization, travels within 1 mm of the inferior shoulder capsule and glenoid rim, at risk during suture passage at the posterior inferior glenoid, can lead to anterior subluxation or coracoid impingement, Glenohumeral Joint Anatomy, Stabilizer, and Biomechanics, Traumatic Anterior Shoulder Instability (TUBS), Humeral Avulsion Glenohumeral Ligament (HAGL), Posterior Shoulder Instability & Dislocation, Multidirectional Shoulder Instability (MDI), Luxatio Erecta (Inferior Glenohumeral Joint Dislocation), Glenohumeral Internal Rotation Deficit (GIRD), Brachial Neuritis (Parsonage-Turner Syndrome), Glenohumeral Arthritis (Shoulder Arthritis), Shoulder Arthroscopy: Indications & Approach, Valgus Extension Overload (Pitcher's Elbow), Lateral Ulnar Collateral Ligament Injury (PLRI), Elbow Arthroscopy: Indications & Approach. Posterior labral tears will demonstrate the absence of the labrum or morphologic distortion, contrast, or fluid infiltration [].Four primary diagnostic characteristics can determine pathologic tearing versus an anatomic variant: intrasubstance signal intensity, margins, orientation, and extension. In all patients, posterior cartilage damage of type 3 to 4, classified according to Outerbridge, with a concomitant posterior labral tear was evident. Tear of the posterior shoulder stabilizers after posterior dislocation: MR imaging and MR arthroscopic findings with arthroscopic correlation. coracoacromial arch and coracoacromial ligament, glenohumeral ligaments - SGHL, MGHL, IGHL (anterior band). In that position the 3-6 o'clock region is imaged perpendicular. Bennett GE: Shoulder and elbow lesions of the professional baseball pitcher. The posterior shoulder capsule plays a significant role in preventing posterior shoulder dislocation, particularly at the extremes of internal humeral rotation, the position in which most posterior dislocations occur. Axial anatomy and checklist. (A) Anteroposterior radiograph of severe glenoid dysplasia showing hypoplasia of the glenoid neck (blue arrow) and coracoid enlargement (orange star). His pain is aggravated when grappling with other wrestlers and when performing push-ups. Bennett lesions are more commonly found in overhead athletes, typically baseball players, and can be visualized on axillary radiographs.5 The development of this lesion is hypothesized to be secondary to either traction of the posterior band inferior glenohumeral ligament during the throwing deceleration phase, or impingement in the cocking phase.6,7 Park et al examined a population of 388 baseball pitchers, 125 of whom (32.2%) had Bennett lesions. Recurrent posterior shoulder instability: diagnosis and treatment. Shoulder Labral Tear Repair Surgery. Additionally, a recent study by Meyer et al9 highlighted the importance of x-rays in evaluation of posterior shoulder instability. 2016 Baseball Sports Medicine: Game Changing Concepts, The Batters Shoulder and Posterior Labral Tears - Christopher Ahmad, MD (BSM #6, 2016), Shoulder360 The Comprehensive Shoulder Course 2023, Shoulder loose body with posterior labral tear with posterior subluxation in 32M. 1998 Sep;171(3):763-8. J Am Med Assoc 117: 510-514, 1941. Not All SLAPs Are Created Equal: A Comparison of Patients with Planned and Incidental SLAP Repair Procedures. Skeletal Radiol. Dr. Ebraheim's educational animated video describes posterior labral tear - posterior shoulder instability. Posterior ossification of the shoulder: the Bennett lesion. Notice the biceps anchor. ALPSA lesions are . When comparing the 2 groups, they found that 12% of patients in the Bennett group had a posterior labral tear on MRI, whereas only 6.8% of patients in the non-Bennett group had a documented posterior labral tear, although the results were not statistically significant.8 Therefore, although Bennett lesions are typically not associated with posterior shoulder instability, it is important to recognize these lesions because they can be associated with posterior labral tears. These are also called ganglion cysts of the shoulder. Glenoid labral tears are the injuries of the glenoid labrum and a possible cause of shoulder pain. Tendonitis of the long head of the biceps. Type in at least one full word to see suggestions list. Look for rim-rent tears of the supraspinatus tendon at the insertion of the anterior fibers. Study the labrum in the 3-6 o'clock position. Crossref, Medline, Google Scholar; 74. 2009; 38(10):967-975. by Herold T, Bachthaler M, Hamer OW, et al. . 5 A type 1 capsule inserts on the labrum, a type 2 capsule inserts on the junction of the labrum and glenoid, and a type 3 capsule inserts more medially on the glenoid ().The typical posterior capsule inserts on the labrum, either at the labral tip or the . Some types of the posterior synovial fold can mimic a posterior labral tear in conventional MRI. On examination, she reports deep posterior shoulder pain when the arm is abducted 90 degrees and maximally . We hypothesized that the accuracy of MRI and MRA was lower than previously reported. Methods: Between 2006 and 2008, 444 patients who had both shoulder arthroscopy and an MRI (non-contrast . (B) Axillary radiograph demonstrating severe glenoid dysplasia with hypoplasia of the posterior glenoid and severe retroversion. The chondral lesion is thought to arise secondary to impaction injury from the humeral head. Which of the following nerves was most likely injured during the procedure? Etiology, diagnosis, and treatment. If the arm is The first part of rehabilitation labral repair involves letting the labrum heal to the bone. The labrum is a band of tough cartilage and connective tissue that lines the rim of the hip socket, or acetabulum. In type III there is a large sublabral recess. The fibers of the subscapularis tendon hold the biceps tendon within its groove. Superior labral anterior posterior (SLAP) tears are injuries of the glenoid labrum. If the pre-test probability was above 90% or below 10% . Results: Advanced MRI techniques of the shoulder joint: current applications in clinical practice. (10a) Ossification is seen along the posterior glenoid (arrows) in a professional baseball pitcher with a history of posterior instability. by Jaideep J. Iyengar, MD; Keith R. Burnett, MD; Wesley M. Nottage, MD Christensen GV, Smith KM, Kawakami J, Chalmers PN. 2016;36(6):1628-47. Fluid should not lie along both sides of the shoulder capsule. Look for supraspinatus-impingement by AC-joint spurs or a thickened coracoacromial ligament. 6). Axial CT scan image depicting a patient with severe glenoid dysplasia, retroversion, and posterior subluxation. First described by Andrews and colleagues in 1985, Snyder later classified lesions of the superior labrum into four types and coined the term SLAP tear (superior labral tear anterior-posterior). Radiol Clin North Am 2016;54(5):801-815. Broadly, clinical unidirectional . On MR arthrography it is customary to combine T1, T1 FS and T2 FS sequences for further assessment. Description. 15,16). MRI of the shoulder second edition (16b) A fat-suppressed T2-weighted coronal image through the posterior shoulder in the same patient reveals a severe strain of the teres minor muscle along the musculotendinous junction (arrows). 2017; 209: 544-551. Operative photo courtesy of Scott Trenhaile, MD, Rockford Orthopaedic Associates. An MRI arthrogram is performed and is normal. MR arthrography had a large number of false-positive readings in this study. government site. MeSH Patients often do not experience frank posterior dislocation events such as that with anterior shoulder instability and more commonly develop attritional lesions. Glenoid dysplasia, also referred to as glenoid hypoplasia and posterior glenoid rim deficiency, is now increasingly recognized as an anatomic variant that predisposes patients to posterior glenohumeral instability. These normal variants are all located in the 11-3 o'clock position. eCollection 2020 Aug. J Orthop. Axis of supraspinous tendon. Glenoid labrum (marked lig.) Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. Fraying of the anterior section means some tearing of the surface with wispy threads emanating from that subchondral cysts and osteophytes (arrow). A wide ligament that surrounds and stabilises the joint is known as the capsule. MRI is well recognized as an effective means to diagnose internal impingement of the shoulder. Failure of one of the acromial ossification centers to fuse will result in an os acromiale. The most common cause for a tear is after a shoulder dislocation when the most common site to tear is the anterior /inferior labrum. On plain radiography of the shoulder, an anteroposterior (AP) view of the shoulder in internal and external rotation, outlet, and axillary views should be obtained. The os acromiale may cause impingement because if it is unstable, it may be pulled inferiorly during abduction by the deltoid, which attaches here. In the healthy state, the humerus sits on the glenoid similar to the way a golf ball rests on a tee. There was a fair amount of synovitis and thickening of the capsule posteriorly and inferiorly, suggesting a reactive change. The rotator cuff is made of the tendons of subscapularis, supraspinatus, infraspinatus and teres minor muscle. Figure 1 is an artist's rendition of a normal shoulder joint as well as the trauma caused by shoulder instability depicted on MRI. (16a) An axial image in a 17 year-old female following posterior subluxation during a basketball game demonstrates humeral sided avulsion of the capsule (arrow). 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 . SLAP tear: A superior labrum anterior to posterior (SLAP) tear occurs at the top of the glenoid (shoulder socket) and extends from the front to the back, where the biceps tendon connects to the shoulder. An official website of the United States government. Eur J Radiol. It is seen in 11% of individuals. (OBQ12.268) McLaughlin, HL. At surgery, we put the labrum back in position against the bone. On MR arthrography it is customary to combine T1, T1 FS and T2 FS sequences for further assessment. Reverse-bankart lesion: Also known as a posterior labral tear, this injury affects the rear and lower ends of the labrum. Weishaupt D, Zanetti M, Nyffeler RW, Gerber C, Hodler J. Posterior glenoid rim deficiency in recurrent (atraumatic) posterior shoulder instability. Mauro et al found increased retroversion in a cohort of 118 patients who were operatively treated for posterior instability in comparison with a group of normal controls, but the authors did not attribute retroversion as a risk factor for failure. We hypothesize that this population will have fewer labral abnormalities than an athletic population. The axillary radiograph is also helpful in the traumatic scenario for identifying a posterior glenoid rim fracture or a reverse Hill-Sachs lesion. On a MR-arthtrogram a sublabral foramen should not be confused with a sublabral recess or SLAP-tear, which are also located in this region. The axial MR-images show an os acromiale with degenerative changes, i.e. Which of the following is the most likely etiology of his complaints? Increased glenoid retroversion increases the risk of posterior shoulder instability by 6 times. Hottya GA, Tirman PF et al. The capsule is a broad ligament that surrounds and stabilizes the joint. (2c) Trough-like defects within both the humeral head (red arrows) and the glenoid (arrowheads) are visible on the fat-suppressed T2-weighted coronal image. Which of the images (Figures A-E) most likely corresponds to the patient's initial diagnosis? Harper and colleagues17 similarly developed a classification scheme with normal, mild, moderate, and severe glenoid dysplasia. If this appearance is present, a capsular tear should be strongly suspected (Fig. Study the cartiage. AJR Am J Roentgenol. Using arthroscopy as the standard, sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were calculated for all MRIs, as well as separately for the non-intra-articular contrast MRI group and the MR arthrography group. When the Burkhead WZ, Rockwood CA Treatment of instability of the shoulder with an exercise program. Introduction. Orthopedic surgeons will tell you that the labrum increases joint stability and serves as an anchor for ligaments and muscles. Successful nonoperative treatment of posterior shoulder instability has had varying rates of success, between 16 and 70% of patients. With increased advancements in CT and MRI, more subtle forms of glenoid dysplasia have been recognized. The shallow socket in the scapula is the glenoid cavity. Radiographics. (10b) A corresponding T2-weighted sagittal view in the same patient confirms the large ossification along the posteroinferior glenoid rim (arrows), compatible with a Bennett lesion. The anterior labrum and glenoid articular cartilage often demonstrate normal morphology one image superior to the . Pagnani MJ, Warren RF Stabilizers of the glenohumeral joint. These are depicted in Figure 17-7. This site needs JavaScript to work properly. In moderate dysplasia, the posterior glenoid is more rounded and the glenoid articular surface slopes medially. The glenohumeral joint has a greater range of motion than any other joint in the body. Chung CB, Sorenson S, Dwek JR and Resnick D. Humeral Avulsion of the Posterior Band of the Inferior Glenohumeral Ligament: MR Arthrography and Clinical Correlation in 17 Patients. J Bone Joint Surg Am 1993; 75:1175-1184. Non-surgical treatment tends to be most successful in patients with a history of atraumatic subluxations, whereas patients who experience an acute, traumatic posterior dislocation are much less likely to report successful outcomes from conservative therapy.19 Non-operative therapy focuses on strengthening the dynamic shoulder stabilizers and activity modification. This type of shoulder labral tear can lead to intermittent symptoms and only occurs in 5-10% of shoulder labral tear patients. A CT scan is typically performed to evaluate posterior bone loss due to either a reverse bony Bankart lesion or attritional bone loss, and to assess degree of retroversion and glenoid dysplasia, and is performed in revision scenarios. This usually happens from an interior shoulder dislocation (a dislocation when the humeral head comes out of the front of the socket). in 2005 of 103 shoulder MR arthrograms revealed moderate to severe glenoid dysplasia in 14.3% of patients, and including mild cases increased the incidence to 39.8%.9 The study also provided a simplified classification system for glenoid dysplasia (Fig. The insertion has a variable range. This is not always the case. In more advanced cases of glenoid dysplasia, hypertrophic changes of the labrum and hyaline cartilage are pronounced. sports. Typically, physical therapy will start the first week or two after surgery. Which of the following is the next best step in management? Posterior Labral Tear, Shoulder Soterios Gyftopoulos, MD, MSc ; Michael J. Tuite, MD To access 4,300 diagnoses written by the world's leading experts in radiology. Images demonstrate a non-displaced tear involving the superficial anteroinferior labrum with associated injury to the adjacent cartilage 4.. Notice that the supraspinatus tendon is parallel to the axis of the muscle. Diagnostic performance of 3D-multi-Echo-data-image-combination (MEDIC) for evaluating SLAP lesions of the shoulder. In patients with glenoid deficiency or large impaction defects, osteotomies and osseous augmentation procedures may be required. 2012 Dec;52(6):622-30. Objective The purpose of this study is to evaluate the accuracy of MR arthrography in detecting isolated posterior glenoid labral injuries using arthroscopy as the reference standard. It can be a traumatic tear due to injury, or it may be degenerative due to normal wear and tear.
