posterior labral tear shoulder mri

Study the attachment of the IGHL at the humerus. Small to moderate glenohumeral joint effusion with synovitis and extension of fluid in the subcoracoid recess. complex injuries to the shoulder. In addition to aiding in the recognition of a locked posterior dislocation, the axillary radiograph is necessary to a complete an orthogonal radiographic analysis. He has full passive and active range of motion of the left shoulder that is symmetrical to his contralateral side. A tear extends across the base of the posterior labrum (arrowheads), and mild posterior subluxation of the humeral head relative to the glenoid is present. J Shoulder Elbow Surg. J Bone Joint Surg Am. Similarly, Bradley and colleagues found that in a cohort of 100 shoulders that underwent arthroscopic capsulolabral repair, patients with posterior instability had significantly greater chondrolabral injury and osseous retroversion in comparison with controls.10 The measurement of glenoid retroversion on 2-dimensional CT scan is performed by using Friedmans method, which has been validated and accepted (Figure 17-5).11 It is generally accepted that normal glenoid version is between 4 to 7 degrees of retroversion. Such lesions are generally found in patients with atraumatic posterior instability. In that position the 3-6 o'clock region is imaged perpendicular. An arthroscopic examination confirmed the MRI findings and showed multiloculated cysts in the inferior labrum, mostly between 5 o'clock to 7 o'clock positions with labral tear. When there is an avulsion of the posterior inferior labrum, and the lesion is incomplete, concealed, or occult, it is called a Kim lesion. (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. Pagnani MJ, Warren RF Stabilizers of the glenohumeral joint. Major NM, Browne J, Domzalski T, Cothran RL, Helms CA. Edelson was the first to define the incidence of subtle forms of glenoid dysplasia by studying scapular specimens from several museum collections.15 Posteroinferior hypoplasia was defined as a dropping away of the normally flat plateau of the posterior part of the glenoid beginning 1.2 cm caudad to the scapular spine (Figure 17-7). These images illustrate the differences between an sublabral recess and a SLAP-tear. The anterior labrum is absent in the 1-3 o'clock position and there is a thickened middle GHL. Of the 444 patients having an MRI and arthroscopy for shoulder pain, 121 had a SLAP diagnosis by MRI and 44 had a SLAP diagnosis by arthroscopy. A Buford complex is a congenital labral variant. 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. A displaced tear of the posterior labrum (arrow) is present. There are 3 types of attachment of the superior labrum at the 12 o'clock position where the biceps tendon inserts. In type II there is a small recess. Often, muscle wasting is seen clearly on MRI, showing atrophy of the muscle and build-up of fat. Diagnosis can be made clinically with positive posterior labral provocative tests and confirmed with MRI studies of the shoulder. MRI Shoulder Labrum Periosteal Stripping. A normal glenoid labrum has a laterally pointing edge and normal posterior labral morphology. Notice MGHL, which has an oblique course through the joint and study the relation to the subscapularis tendon. No Comments Other radiographic lesions that may be associated with posterior labral pathology and instability include the Bennett lesion, which is an extra-articular posterior ossification of the posterior inferior glenoid. 1998 Sep;171(3):763-8. The axial MR-images show an os acromiale with degenerative changes, i.e. On these axial images a Buford complex can be identified. Although increased glenoid retroversion is a risk factor for posterior shoulder instability, there is little evidence to support the claim that increasing glenoid retroversion is associated with worse outcomes following posterior labral repair.12 Hurley et al found that patients with symptomatic posterior instability and glenoid retroversion of greater than 9 degrees had higher recurrence rates after open soft-tissue procedures.13 Conversely, Bigliani and colleagues performed CT scans for 16 of 35 shoulders prior to an open posterior capsular shift and found the average retroversion was 6 degrees.14 Their surgical cohort had an 80% success rate but they did not attribute their failures to osseous anatomy. Both tests may . Look for tears of the infraspinatus tendon. An area of capsular irregularity (arrow) is apparent as well. We hypothesized that the accuracy of MRI and MRA was lower than previously reported. On examination, she reports deep posterior shoulder pain when the arm is abducted 90 degrees and maximally . 2005;184: 984-988. . Before Posterior periosteum (arrowheads) is extensively stripped but remains attached to the posterior labrum. eCollection 2020 May-Jun. It is important to recognise these variants, because they can mimick a SLAP tear. These normal variants are all located in the 11-3 o'clock position. Uncategorized. Shoulder Labral Tear Repair Surgery. Diagnosis is made clinically with presence of increased anterior and posterior humeral translation, a sulcus sign, and overall increased . Numerous capsular abnormalities have been described in patients with posterior glenohumeral instability. Shoulder dislocations account for 90% of shoulder instability cases and usually occur after a fall during sport or work activities ().This glenohumeral joint instability has been defined with the acronyms TUBS (traumatic, unidirectional, Bankart, surgery is the main treatment) ().Associated injuries to the labrum, to the glenoid bone, described in up to 40% of the cases (), and . It is present in 5% of the population. At this level also look for Bankart lesions. Imaging in three planes is advisable and additional orthogonal planes may be included in the protocol for a detailed assessment of the lesion. A study in cadavers. Notice the smooth borders unlike the margins of a SLAP-tear. Measurement of Friedmans angle and posterior humeral head subluxation (yellow lines depict Friedmans angle; red line depicts percentage of posterior humeral head subluxation). Modern imaging techniques, in particular MRI, have greatly increased our ability to accurately diagnose posterior glenohumeral instability, and accurate recognition and characterization of the relevant abnormalities are critical for proper diagnosis and patient management.5, Multiple shoulder structures are important in resisting shoulder instability. Notice that the biceps tendon is attached at the 12 o'clock position. This is not always the case. Dislocation of the long head of the biceps will inevitably result in rupture of part of the subscapularis tendon. Clavert P. Glenoid Labrum Pathology. A sublabral foramen or sublabral hole is an unattached anterosuperior labrum at the 1-3 o'clock position. 2019 Nov 7;19:199-202. doi: 10.1016/j.jor.2019.10.015. It helps provide stability to the shoulder by . Ultrasound will also show a shoulder ganglion cyst and the effects of muscle wasting. Appendicitis - Pitfalls in US and CT diagnosis, Acute Abdomen in Gynaecology - Ultrasound, Transvaginal Ultrasound for Non-Gynaecological Conditions, Bi-RADS for Mammography and Ultrasound 2013, Coronary Artery Disease-Reporting and Data System, Contrast-enhanced MRA of peripheral vessels, Vascular Anomalies of Aorta, Pulmonary and Systemic vessels, Esophagus I: anatomy, rings, inflammation, Esophagus II: Strictures, Acute syndromes, Neoplasms and Vascular impressions, TI-RADS - Thyroid Imaging Reporting and Data System, The Abduction External Rotation (ABER) View for MRI of the Shoulder. Introduction. A mid-substance tear of the posterior capsule is present with the medial component appearing lax and retracted (arrow). Eur J Radiol. Glenoid dysplasia/hypoplasia occurred in 19% to 35% of specimens.15,16 Additionally, several studies have identified that subtle posteroinferior glenoid deficiency and hypoplasia are significantly associated with posterior labral tears and symptomatic posterior shoulder instability.1719 Weishaupt et al18 used CT arthrograms to determine the incidence and severity of glenoid dysplasia in a population of patients with atraumatic posterior shoulder instability. This procedure greatly enhances the diagnostic accuracy by allowing tears . A shoulder labral tear can occur due to repetitive overhead use, a lifting injury, a fall on the arm, a sudden pull on the arm, or having the arm twisted at the shoulder joint. Methods: Normal glenoid morphology is present. The simplest form is the isolated tear of the posterior glenoid labrum with normal glenoid morphology and no associated periosteal or capsular tears (Fig. The ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff. The retracted end of the subscapularis (asterisk) is also visible compatible with a full thickness tear. Posterior subluxation of the humeral head is also apparent. Locked posterior subluxation of the shoulder: diagnosis and treatment. This can result in the damage to the anterior or front part of the labrum. Look for supraspinatus-impingement by AC-joint spurs or a thickened coracoacromial ligament. HHS Vulnerability Disclosure, Help Unlike the anterior labrum, rarely do we have a posterior dislocation of the shoulder. 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. Posterior capsular rupture causing posterior shoulder instability: a case report. scan or magnetic resonance imaging (MRI) scan may be ordered for a glenoid labrum tear diagnosis. Imaging of Posterior Shoulder Instability, Josef K. Eichinger, MD, FAOA and Joseph W. Galvin, DO, FAAOS. (B) Axillary radiograph demonstrating severe glenoid dysplasia with hypoplasia of the posterior glenoid and severe retroversion. On conventional MR labral tears are best seen on fat-saturated fluid-sensitive sequences. Study the cartiage. 4). Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), on Imaging of Posterior Shoulder Instability. 2012;132(7):905-19. The biceps tendon is medially dislocated (short arrow). In part III we will focus on impingement and rotator cuff tears. In cases of severe dysplasia, advanced rounding and posterior sloping of the posterior glenoid is seen, and pronounced thickening of the labrum and other adjacent posterior soft tissues is apparent. Our data indicated that while MRI could exclude a SLAP lesion (NPV = 95 %), MRI alone was not an accurate clinical tool. a pointed glenoid on axial imaging sequences is a normal-appearing glenoid without dysplasia, a lazy J has a rounded appearance of the posterior inferior glenoid, and a delta glenoid is a triangular osseous deficiency. We concluded that even with intra-articular contrast, MRI had limitations in the ability to diagnose surgically proven SLAP lesions. Clipboard, Search History, and several other advanced features are temporarily unavailable. 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 . Posterior labral tear; < 15 decrease in affected shoulder internal rotation compared to contralateral shoulder . The appearance is thought to be due to failure of ossification of the more inferior of the two ossification centers of the glenoid, resulting in a cartilage cap replacing the bone defect.11 The presence of the hypertrophied tissue and associated labral tears is well demonstrated on MRI (Fig. (10a) Ossification is seen along the posterior glenoid (arrows) in a professional baseball pitcher with a history of posterior instability. A 22-year-old male wrestler presents to your clinic with complaints of deep left shoulder pain for the past 6 weeks. Imaging Studies. Posterior shoulder instability is a relatively rare phenomenon compared to anterior instability, comprising only 5-10% of all shoulder instability. The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 o'clock position, Since that time, other authors have expanded this classification to the current . In addition to the discrepancy in posterior labral tear evaluations, radiologist 1 documented more pathology throughout the shoulder than radiologist 2. . Also, although better visualized on MRA imaging, a hypertrophied posterior glenoid labrum is evident in patients with glenoid dysplasia (Figure 17-8). 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. Normal Labral Anatomy. The labrum is a band of tough cartilage and connective tissue that lines the rim of the hip socket, or acetabulum. by Michael Zlatkin. If this appearance is present, a capsular tear should be strongly suspected (Fig. The shoulder joint is a ball and socket joint that connects the bone of the upper arm (humerus) with the shoulder blade (scapula). Treatment of the labral tears in these scenarios involves treatment of the shoulder dislocation and stabilising the shoulder. A Treatise on Dislocations and Fractures of the Joints. The radiologic diagnosis and surgical evaluation were compared to determine the accuracy of diagnosing a SLAP lesion by MRI. Arthroscopic Posterior Labral Repair - Randy S. Schwartzberg, M.D. Additionally, a recent study by Meyer et al9 highlighted the importance of x-rays in evaluation of posterior shoulder instability. When you have a excessive posterior force on an adducted arm the resultant is a posterior labral tear. 2006; 240(1):152-160. Surgery may be required if the tear gets worse or does not improve after physical therapy. McLaughlin, HL. (14c) An arthroscopic examination confirms the tear in the posterior capsule (arrow), which was subsequently repaired. 2012 Jan;21(1):13-22 Indirect MR arthrography of the shoulder: use of abduction and external rotation to detect full- and partial-thickness tears of the supraspinatus tendon. 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). MRI of the shoulder has been found to be accurate in the diagnosis of labral tears. 2011 Sep;27(9):1304-7. Sensitivity was 66 %, and specificity was 77 %. posterior labral tear surgery. Tearing of the inferior glenohumeral ligament at the humeral attachment (blue arrow) is also evident. In Shoulder MR-Part I we will focus on the normal anatomy and the many anatomical variants that may simulate pathology. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Chmiel-Nowak M, Sheikh Y, Feger J, et al. Orthop J Sports Med. A Meta-Analysis of the Diagnostic Test Accuracy of MRA and MRI for the Detection of Glenoid Labral Injury. A hip (acetabular) labral tear is damage to cartilage and tissue in the hip socket. Figure 17-3. The shoulder is primarily a ball and socket joint made up of the humerus (ball) and the glenoid (socket). De Maeseneer M, Van Roy F, Lenchik L et al. Clin Orthop Relat Res 1993 : 85-96. Accessibility Treatment may be nonoperative or operative depending on chronicity of symptoms, degree of instability, and patient activity demands. 1999 May 15;318(7194):1322-3 Christensen GV, Smith KM, Kawakami J, Chalmers PN. In part II we will discuss shoulder instability. This type of shoulder labral tear can lead to intermittent symptoms and only occurs in 5-10% of shoulder labral tear patients. Check for errors and try again. 2016;36(6):1628-47. Without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. AJR Am J Roentgenol. 15 Imaging of the patient in the ABER position can greatly increase the conspicuity of an ALPSA lesion, which can easily be overlooked on a routine MRI of the shoulder or on the standard axial sequence of an MRA. Numerous labral abnormalities may be encountered in patients with posterior glenohumeral instability. There are many labral variants. On conventional MR labral tears are best seen on fat-saturated fluid-sensitive sequences. I don't have pain generally at all. Notice rotator cuff muscles and look for atrophy. Figure 1 is an artist's rendition of a normal shoulder joint as well as the trauma caused by shoulder instability depicted on MRI. Occasionally, a SLAP (superior labrum, anterior and posterior) fracture, which represents a superior humeral head compression . 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. In the event of a shoulder dislocation, the . Not All SLAPs Are Created Equal: A Comparison of Patients with Planned and Incidental SLAP Repair Procedures. Types of labral tears. They involve the superior glenoid labrum, where the long head of biceps tendon inserts. 2000 Jan;214(1):267-71 15,16). A small chondral defect is present (arrowhead) adjacent to the free edge of the posterior labrum. Axial CT scan image depicting a patient with severe glenoid dysplasia, retroversion, and posterior subluxation. Articular cartilage is maintained. Bennett GE: Shoulder and elbow lesions of the professional baseball pitcher. Type in at least one full word to see suggestions list. Results: Notice coracoclavicular ligament and short head of the biceps. Arthroscopy. 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. Posterior shoulder dislocations can result in posterior labral tears. A posterior labral tear (reverse Bankart) is also present (arrowhead), and a bone bruise is seen within the anterior humeral head (asterisk). Keith W. Harper1, Clyde A. Helms1, Clare M. Haystead1 and Lawrence D. Higgins Glenoid Dysplasia: Incidence and Association with Posterior Labral Tears as Evaluated on MRI. What is Anterosuperior acetabular labrum? The glenoid labrum is a rim of cartilage attached to the glenoid rim. Glenoid labrum (marked lig.) Posterior Labral Tear. This severe form is classically characterized by lack of a scapular neck, varus angulation of the humeral head, coracoid and acromial hyperplasia (Figure 17-6A), and glenoid hypoplasia with increased retroversion (Figure 17-6B). Arthroscopy. Posterior labral tearing was apparent on contiguous images (not shown). Crossref, Medline, Google Scholar; 74. What is your diagnosis? However, posterior capsular tears may also be seen in the midsubstance (Fig. His pain is aggravated when grappling with other wrestlers and when performing push-ups. Labral repair or resection is performed. On MR arthrography it is customary to combine T1, T1 FS and T2 FS sequences for further assessment. 2012 Sep;81(9):2343-7. doi: 10.1016/j.ejrad.2011.07.006. Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. MRI can rule out other causes of shoulder pain. Magnetic resonance imaging, magnetic resonance arthrography and ultrasonography for assessing rotator cuff tears in people with shoulder pain for whom surgery is being considered. Fluid undermines a tear of the posterior glenoid labrum (arrow) in a 42 year-old male with persistent posterior shoulder pain. Posterior instability of the shoulder can vary from minor symptoms and findings to dramatic events resulting in extensive, complex injuries to the shoulder. Surgical Management of Superior Labral Tears in Athletes: Focus on Biceps Tenodesis. To investigate the utility of MRI, the researchers identified 41 patients who had undergone shoulder capsulorrhaphy by one of two senior surgeons over a two-year period. Consecutive fat-suppressed proton density-weighted axial images at the mid glenoid in a football player with persistent shoulder pain reveals mild glenoid dysplasia, with a rounded contour of the posterior glenoid rim (arrows). Diagnosis can be made clinically with positive posterior labral provocative tests and confirmed with MRI studies of the shoulder. MeSH This sublabral recess can be difficult to distinguish from a SLAP-tear or a sublabral foramen. Posterior ossification of the shoulder: the Bennett lesion. 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 . These shoulder MRI findings in middle-aged populations emphasize the need for supporting clinical judgment when making treatment decisions for this patient population. The following algorithm has been previously proposed 25. There are also newer treatments to consider that don't involve surgery. A useful indirect sign to be aware of, whether using MR arthrography or routine MR, is to recognize that normally the shoulder capsule should only be outlined by fluid along its inner margin. Fluid should not lie along both sides of the shoulder capsule. 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. Advances in knowledge:: On a direct MR arthrographic image, a posterior capsular synovial fold may be a normal anatomic variant. They developed a classification system in which a pointed glenoid on axial imaging sequences is a normal-appearing glenoid without dysplasia, a lazy J has a rounded appearance of the posterior inferior glenoid, and a delta glenoid is a triangular osseous deficiency. SLAP tears can cause pain and range-of-motion problems in the shoulder labrum, the biceps tendon or both. (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). (B) Axillary radiograph of locked posterior glenohumeral dislocation. MRA for SLAP - Is the threshold for referral too low? Which of the listed structures augments the posterior-inferior glenohumeral ligament and is a static restraint to posterior translation of the humeral head on the glenoid when the shoulder is forward flexed, adducted, and internally rotated?
