Severe glenoid dysplasia or hypoplasia is a rare condition due to either brachial plexus birth palsy or a developmental abnormality with lack of stimulation of the inferior glenoid ossification center. Arthroscopy. (14c) An arthroscopic examination confirms the tear in the posterior capsule (arrow), which was subsequently repaired. Patients with labral tears may present with a wide range of symptoms (depends on the injury type), which are often non-specific: Labral injuries can result from acute trauma (like shoulder dislocation or direct blow) or repetitive overuse. Arch Orthop Trauma Surg. Harper and colleagues17 similarly developed a classification scheme with normal, mild, moderate, and severe glenoid dysplasia. J Shoulder Elbow Surg. When the Due to the tension by the anterior band of the inferior GHL labral teras will be easier to detect. The anterior labrum is absent in the 1-3 o'clock position and there is a thickened middle GHL. Evaluate the TCO of your PACS download >, 750 Old Hickory Blvd, Suite 1-260Brentwood, TN 37027, Focus on Musculoskeletal and Neurological MRI, Collateral Ligament Injuries of the Fingers, Tannenbaum E and Sekiya JK. The chondral lesion is thought to arise secondary to impaction injury from the humeral head. Sometimes at this level labral tears at the 3-6 o'clock position can be visualized. They involve the superior glenoid labrum, where the long head of biceps tendon inserts. Overall, MRI had an accuracy of 76 %, a PPV of 24 %, and a NPV of 95 %. 2006; 240(1):152-160. 2019 Dec 12;20(1):598. doi: 10.1186/s12891-019-2986-1. scan or magnetic resonance imaging (MRI) scan may be ordered for a glenoid labrum tear diagnosis. When you plan the coronal oblique series, it is best to focus on the axis of the supraspinatus tendon. 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. Articular cartilage is maintained. Purpose: 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. Fraying of the anterior section means some tearing of the surface with wispy threads emanating from that Injuries isolated to labrum and capsule can often be successfully repaired with arthroscopic techniques including capsulolabral repair, capsular shift, and capsular shrinkage. An axial image in a 53 year-old male following an acute traumatic posterior dislocation reveals tears of the posterior labrum (arrow) and posterior capsule (arrowhead). 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. The glenoid cavity is the shallow socket of the scapula. a painful feeling of clicking, popping or grinding in the shoulder during movement. 11). An MRI arthrogram is performed and is normal. They all attach to the greater tuberosity. A normal glenoid labrum has a laterally pointing edge and normal posterior labral morphology. The ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff. 2009; 38(10):967-975. by Herold T, Bachthaler M, Hamer OW, et al. . 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. In type I there is no recess between the glenoid cartilage and the labrum. 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. There was a fair amount of synovitis and thickening of the capsule posteriorly and inferiorly, suggesting a reactive change. SLAP tears can cause pain and range-of-motion problems in the shoulder labrum, the biceps tendon or both. Look for impingement by the AC-joint. difficulty performing normal shoulder . 12) or at the humeral attachment (Fig. 1999 May 15;318(7194):1322-3 His pain is aggravated when grappling with other wrestlers and when performing push-ups. The rotator cuff muscles and tendons act to stabilize the shoulderjoint during movements. American Journal of Roentgenology. (B) Axillary radiograph demonstrating severe glenoid dysplasia with hypoplasia of the posterior glenoid and severe retroversion.

A 27-year-old male bodybuilder presents to the office with vague, deep shoulder pain and weakness with his bench press. Notice red arrow indicating a small Perthes-lesion, which was not seen on the standard axial views. Posterior capsular rupture causing posterior shoulder instability: a case report. Posterior ossification of the shoulder: the Bennett lesion. In the event of a shoulder dislocation, the . 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. MeSH Often, muscle wasting is seen clearly on MRI, showing atrophy of the muscle and build-up of fat. 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. Materials and methods In this cross-sectional study, non-athletic young adults age 18-29 with no history of shoulder pain received bilateral shoulder MRIs . This usually happens from an interior shoulder dislocation (a dislocation when the humeral head comes out of the front of the socket). This top area is also where the biceps tendon attaches to the labrum. A 22-year-old male wrestler presents to your clinic with complaints of deep left shoulder pain for the past 6 weeks. Figure 17-1. 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. Hottya GA, Tirman PF, Bost FW, Montgomery WH, Wolf EM, Genant HK. The glenoid labrum is a rim of cartilage attached to the glenoid rim. Orthop Traumatol Surg Res. Glenoid labral tears are the injuries of the glenoid labrum and a possible cause of shoulder pain. PMC Ferrari JD, Ferrari DA, Coumas J, Pappas AM. The insertion has a variable range. The posterior labrum is stressed with an abducted arm and posterior force. Patients often do not experience frank posterior dislocation events such as that with anterior shoulder instability and more commonly develop attritional lesions. Fig. Radiology 2008; 248:185193. In shoulders with posterior instability, the acromion is situated higher and is oriented more horizontally in the sagittal plane than in normal shoulders and those with anterior instability. 2011 May;196(5):1139-44. doi: 10.2214/AJR.08.1734.

This is a common injury for athletes such as baseball pitchers and . That is, the labrum helps the shoulder from slipping out of its joint. 8600 Rockville Pike MR interpreters should be aware that at times capsular tears are quite subtle. 2000 Jan;214(1):267-71 doi: 10.1002/14651858.CD009020.pub2. Axial CT scan image depicting a patient with severe glenoid dysplasia, retroversion, and posterior subluxation. Orthopedic surgeons will tell you that the labrum increases joint stability and serves as an anchor for ligaments and muscles. The most common cause of a cyst of the shoulder is a labral tear. Clinical Relevance: . On examination, she reports deep posterior shoulder pain when the arm is abducted 90 degrees and maximally . (SBQ16SM.25) Christensen GV, Smith KM, Kawakami J, Chalmers PN. 2012 Sep;81(9):2343-7. doi: 10.1016/j.ejrad.2011.07.006. Figure 17-6. Description. Burkhead WZ, Rockwood CA Treatment of instability of the shoulder with an exercise program. There was a posterior labrum tear. 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). Such injuries may be referred to as reverse HAGL (humeral avulsion of the glenohumeral ligament) or RHAGL lesions (Fig. If there is a related partial thickness rotator cuff tear, there may also be lateral (on the side) pain. If the arm is posterior labral tear surgery. Introduction. (10a) Ossification is seen along the posterior glenoid (arrows) in a professional baseball pitcher with a history of posterior instability. A fold is more commonly occur in the posterosuperior and posteroinferior capsular portions. Imaging in three planes is advisable and additional orthogonal planes may be included in the protocol for a detailed assessment of the lesion. Notice rotator cuff muscles and look for atrophy. ORTHOPEDICS August 2010;33(8):562. by Schreinemachers SA, van der Hulst VP, Willems WJ, Bipat S, van der Woude HJ. Normal glenoid morphology is present. Imaging Studies. Background:The literature demonstrates a high prevalence of asymptomatic knee and hip findings on magnetic resonance imaging (MRI) in athletes. 2005;184: 984-988. Plain radiographs in patients with posterior shoulder instability are an important and critical adjunct to making the diagnosis of posterior shoulder instability. A posterior labral tear is referred to as a reverse Bankart lesion, or attenuation of the posterior capsulolabral complex, and commonly occurs due to repetitive microtrauma in athletes. Posterior shoulder dislocations can result in posterior labral tears. A recess more than 3-5 mm is always abnormal and should be regarded as a SLAP-tear. Detection of partial-thickness supraspinatus tendon tears: is a single direct MR arthrography series in ABER position as accurate as conventional MR arthrography? Surg Clin North Am. Dougherty MC, Kulenkamp JE, Boyajian H, Koh JL, Lee MJ, Shi LL. . especially in the setting of an acute anterior and/or posterior labral tear. Advances in knowledge:: On a direct MR arthrographic image, a posterior capsular synovial fold may be a normal anatomic variant. Future larger studies are needed to confirm these findings. Methods: In a 20 year-old football player following acute injury, a reverse Bankart lesion is present. There is . He has positive Kim and jerk tests and reproduction of symptoms with the shoulder in forward flexion, adduction, and internal rotation. ADVERTISEMENT: Supporters see fewer/no ads. 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? {"url":"/signup-modal-props.json?lang=us\u0026email="}, Chmiel-Nowak M, Sheikh Y, Feger J, et al. Notice that the supraspinatus tendon is parallel to the axis of the muscle. Crossref, Google Scholar; 73. eCollection 2021. 2012 Jan;21(1):13-22 Uncategorized. Major NM, Browne J, Domzalski T, Cothran RL, Helms CA. Posterior instability most often occurs either as a result of high force direct trauma to the shoulder such as from a motor vehicle accident or indirect trauma such as from seizures or electrocution. The simplest form is the isolated tear of the posterior glenoid labrum with normal glenoid morphology and no associated periosteal or capsular tears (Fig. Posterior shoulder instability is becoming increasingly recognized in young, athletic populations, especially in the military.13 Compared to anterior shoulder instability, posterior instability can be more challenging to diagnose both clinically and radiographically. 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. The glenohumeral joint has the following supporting structures: The tendon of the subscapularis muscle attaches both to the lesser tuberosity aswell as to the greater tuberosity giving support to the long head 10 A paralabral cyst indicates the presence of a labral tear. 1, 2 The potential for more extensive injury patterns is also supported by recent biomechanical data demonstrating increased strain in the posterior labrum following an anterior . "If physical therapy fails and the athlete still can't complete overhead motions, or the shoulder continues to dislocate, surgical treatment might be required to reattach the torn ligaments and labrum to the . 14). Scroll through the images and notice the unattached labrum at the 12-3 o'clock position at the site of the sublabral foramen. The authors found that specific acromial morphology on scapular-Y x-rays is significantly associated with the direction of glenohumeral instability. Diagnosis . This sublabral recess can be difficult to distinguish from a SLAP-tear or a sublabral foramen. Look for rim-rent tears of the supraspinatus tendon at the insertion of the anterior fibers. Skeletal Radiol. 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. The first part of rehabilitation labral repair involves letting the labrum heal to the bone. 2009 Jan;192(1):86-92. doi: 10.2214/ajr.08.1097. postulated that dislocations result in a 360 degree injury, with trauma to the anterior labrum, resulting in changes posteriorly, and vice versa. Also, it allows preoperative planning if a posterior bone block procedure is planned. Reverse-bankart lesion: Also known as a posterior labral tear, this injury affects the rear and lower ends of the labrum. Figure 1 is an artist's rendition of a normal shoulder joint as well as the trauma caused by shoulder instability depicted on MRI. Lenza M, Buchbinder R, Takwoingi Y, Johnston RV, Hanchard NC, Faloppa F. Cochrane Database Syst Rev. Diagnostic arthroscopy revealed no significant glenohumeral articular defects. Imaging of superior labral anterior to posterior (SLAP) tears of the shoulder. [ 41] Findings are usually normal. by Michael Zlatkin. Ultrasound will also show a shoulder ganglion cyst and the effects of muscle wasting. Axis of supraspinous tendon. In part III we will focus on impingement and rotator cuff tears. 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). Arthroscopy. In more advanced cases of glenoid dysplasia, hypertrophic changes of the labrum and hyaline cartilage are pronounced. Acute traumatic posterior shoulder dislocation: MR findings. The IGHL, labrum, and periosteum are stripped and medially displaced along the anterior neck of the scapula. Posterior labral periosteal sleeve avulsion injury (POLPSA) in a 19 year-old football player following acute injury. 2012 Dec;52(6):622-30. MRI Shoulder Labrum Periosteal Stripping. The shoulder capsule, including the glenohumeral ligaments, is one of the most important structures for restricting posterior translation of the humeral head.6The subscapularis, and to a lesser extent the infraspinatus and teres minor muscles, provide dynamic restriction of posterior humeral head translation.7The rotator interval is also thought to play a role, though its significance is somewhat controversial.8. 2021 May 5;12:61-71. doi: 10.2147/OAJSM.S266226. An official website of the United States government. We hypothesized that the accuracy of MRI and MRA was lower than previously reported. Normal anatomy. 4. Usually it is an incidental finding and regarded as a normal variant. 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. Both tests may . Rotator cuff tears in the context of posterior shoulder instability or dislocation were once thought to be rare. Measurement of Friedmans angle and posterior humeral head subluxation (yellow lines depict Friedmans angle; red line depicts percentage of posterior humeral head subluxation). We hypothesized that the accuracy of MRI and MRA was lower than previously reported. A displaced tear of the posteroinferior labrum is present, with a torn piece of periosteum (arrow) remaining attached to the posterior labrum. Figure 1. Galvin et al performed a retrospective comparative outcomes analysis of 37 patients, mean age 28 years, who underwent arthroscopic posterior labral repair for symptomatic posterior shoulder instability with a mean follow-up of 3.1 years. Treatment of the labral tears in these scenarios involves treatment of the shoulder dislocation and stabilising the shoulder. The axial MR-images show an os acromiale with degenerative changes, i.e. Posterior shoulder subluxation or dislocation is also one of the rare entities that may result in tears of the teres minor muscle.18 MR allows rapid evaluation of the status of the cuff following posterior dislocation, and prompt diagnosis of such lesions avoids delays in treatments that may lead to irreversible fatty atrophy of cuff musculature (Figs. Not All SLAPs Are Created Equal: A Comparison of Patients with Planned and Incidental SLAP Repair Procedures. Notice smooth undersurface of infraspinatus tendon and normal anterior labrum. 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. J Bone Joint Surg Am 1993; 75:1175-1184. The .gov means its official. 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 type III there is a large sublabral recess. government site. The glenohumeral joint has a greater range of motion than any other joint in the body. found in 3-5% of patients undergoing routine MRI of the shoulder 12, 13 Denervation of muscle is identified on MR images initially by the presence of diffuse, homogeneous muscle . Figure 17-5. The capsule is a broad ligament that surrounds and stabilizes the joint. Without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. Our data indicated that while MRI could exclude a SLAP lesion (NPV = 95 %), MRI alone was not an accurate clinical tool. These are depicted in Figure 17-7. As a result posterior shoulder instability may present with vague shoulder pain, and a clinical examination is less demonstrative than anterior shoulder instability and may therefore be more difficult to diagnose. 2015;101(1 Suppl):S19-24.
