In this post we look at Periosteal Stripping. Between 2006 and 2008, 444 patients who had both shoulder arthroscopy and an MRI (non-contrast or MR arthrography) for shoulder pain at our institution prior to surgery were identified and included in the study. A hip (acetabular) labral tear is damage to cartilage and tissue in the hip socket. It is present in approximately 1.5% of individuals. Radiographics. (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). Treatment of the labral tears in these scenarios involves treatment of the shoulder dislocation and stabilising the shoulder. Common symptoms of a SLAP tear include: dull or aching pain in the shoulder, especially while lifting over the head. A displaced tear of the posterior labrum (arrow) is present. 13) of the posterior capsule. [ 41] Findings are usually normal. 3-T MRI of the shoulder: is MR arthrography necessary? The .gov means its official. When we assess the shoulder labrum there are 7 areas to look at which have some association with labral tears. If the pre-test probability was above 90% or below 10% . In part III we will focus on impingement and rotator cuff tears. In type II there is a small recess. When the labrum gets damaged or torn, it puts the shoulder at increased risk for looseness and dislocation. In this chapter we will review imaging findings of posterior instability on standard radiographs, CT scan, MRI, and magnetic resonance arthrogram (MRA), and 3-dimensional (3D) reconstruction CT and 3D MRI, which assist in the diagnosis and treatment of symptomatic posterior shoulder instability. De Coninck T, Ngai S, Tafur M, Chung C. Imaging the Glenoid Labrum and Labral Tears. What is Anterosuperior acetabular labrum? It is a condition referred to as an internal impingement. The management of these labrum injuries will depend on the classification, severity of the injury and the stability of the shoulder. Look for tears of the infraspinatus tendon. Recurrent posterior shoulder instability: diagnosis and treatment. sports. The first part of rehabilitation labral repair involves letting the labrum heal to the bone. The image shows the typical findings of a sublabral recess. Imaging of superior labral anterior to posterior (SLAP) tears of the shoulder. Wirth MA, Lyons FR, Rockwood CA Jr. Hypoplasia of the glenoid: a review of sixteen patients. Posterior subluxation of the humeral head is readily apparent. Follow me on twitter:https://twitter.com/#!/DrEbr. J Am Med Assoc 117: 510-514, 1941. It helps provide stability to the shoulder by . government site. (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. We hypothesized that the accuracy of MRI and MRA was lower than previously reported. the removal of the acromion distal to the synchondrosis may further destabilize the synchondrosis and allow for An official website of the United States government. Uncategorized. difficulty performing normal shoulder . Pagnani MJ, Warren RF Stabilizers of the glenohumeral joint. 2021 May 5;12:61-71. doi: 10.2147/OAJSM.S266226. Look for supraspinatus-impingement by AC-joint spurs or a thickened coracoacromial ligament. 2020 Aug 27;8(8):2325967120941850. doi: 10.1177/2325967120941850. An anatomy drawing of a shoulder labrum. CT and MR Arthrography of the Normal and Pathologic Anterosuperior Labrum and Labral-Bicipital Complex. 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. Successful nonoperative treatment of posterior shoulder instability has had varying rates of success, between 16 and 70% of patients. 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 ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff. Non-contrast MRI had an accuracy of 85 %, sensitivity of 36 %, and a PPV of 13 %. These are depicted in Figure 17-7. Hottya GA, Tirman PF, Bost FW, Montgomery WH, Wolf EM, Genant HK. scan or magnetic resonance imaging (MRI) scan may be ordered for a glenoid labrum tear diagnosis. It . The posterior capsule is torn at the humeral attachment (arrow). Labral tears, such as a SLAP tear that cause a paralabral cyst, can occur due to trauma (dislocation), repetitive movement . As joint instability is often present, capsuloplasty may be added to the procedure. Typically, physical therapy will start the first week or two after surgery. Once thought to be a relatively rare entity, a study by Harper et al. 4). 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. Federal government websites often end in .gov or .mil. 5). 4B), which is what one would intuitively expect. When there is an avulsion of the posterior inferior labrum, and the lesion is incomplete, concealed, or occult, it is called a Kim lesion. It is important to recognise these variants, because they can mimick a SLAP tear. 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. (14b) In a 39 year-old weightlifter with persistent posterior shoulder pain and instability, the axial image reveals the posterior capsule outlined by arthrographic fluid along both sides of the capsule, strongly suggestive of a capsular tear. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. When you plan the coronal oblique series, it is best to focus on the axis of the supraspinatus tendon. No Comments Evaluation and management of posterior shoulder instability. They may extend into the tendon, involve the glenohumeral ligaments or extend into other quadrants of the labrum. Orthop J Sports Med. eCollection 2020 Aug. J Orthop. Wuennemann F, Kintzel L, Zeifang F, Maier MW, Burkholder I, Weber MA, Kauczor HU, Rehnitz C. BMC Musculoskelet Disord. Imaging studies therefore are an important adjunct to the diagnosis and treatment of posterior shoulder instability. These normal variants are all located in the 11-3 o'clock position. Radiographs are normal, and an MRI arthrogram is shown in Figure A. postulated that dislocations result in a 360 degree injury, with trauma to the anterior labrum, resulting in changes posteriorly, and vice versa. A Treatise on Dislocations and Fractures of the Joints. 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. 3, 19, 31 Our results demonstrate a success rate of nonoperative treatment of 52% at a minimum of 2 years after MRI confirmation of posterior labral tear. The most common symptoms of a shoulder labrum tear can occur intermittently. 1985 Sep-Oct;13(5):337-41 Introduction. Overall, an MRI scan will clearly show the ganglion cyst in the shoulder and whether it compresses the nerve. On examination, she reports deep posterior shoulder pain when the arm is abducted 90 degrees and maximally . We concluded that even with intra-articular contrast, MRI had limitations in the ability to diagnose surgically proven SLAP lesions. 7-9). Illustration by Biodigital. MRI. 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. Ultrasound will also show a shoulder ganglion cyst and the effects of muscle wasting. Not All SLAPs Are Created Equal: A Comparison of Patients with Planned and Incidental SLAP Repair Procedures. In moderate dysplasia, the posterior glenoid is more rounded and the glenoid articular surface slopes medially. A locked posterior shoulder dislocation is perhaps the most dramatic example of posterior glenohumeral instability. Lenza M, Buchbinder R, Takwoingi Y, Johnston RV, Hanchard NC, Faloppa F. Cochrane Database Syst Rev. Shah N and Tung GA. 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. Usually it is an incidental finding and regarded as a normal variant. However, imaging studies do not always demonstrate obvious pathologic findings and thus a nuanced approach to the interpretation of x-rays, computed tomography (CT), and magnetic resonance imaging (MRI) is necessary to elucidate and identify subtle findings that can enable the clinician to make the correct diagnosis. 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. Evaluation of the glenoid labrum with 3-T MRI: is intraarticular contrast necessary? Occasionally, a SLAP (superior labrum, anterior and posterior) fracture, which represents a superior humeral head compression . It is not healed. Hill Sachs lesions are only seen at the level of the coracoid. Diagnosis can be made clinically with positive posterior labral provocative tests and confirmed with MRI studies of the shoulder. Notice that the biceps tendon is attached at the 12 o'clock position. The shallow socket in the scapula is the glenoid cavity. Articular cartilage is maintained. Study the cartiage. 2009 Jan;192(1):86-92. doi: 10.2214/ajr.08.1097. Simoni P, Scarciolla L, Kreutz J, Meunier B, Beomonte Zobel B. J Sports Med Phys Fitness. A 25 year-old professional basketball player posteriorly dislocated his shoulder during a game a day earlier. 3. The labrum in the shoulder joint is a vital component that helps stabilize the humerus and shoulder blade during movement. However, posterior capsular tears may also be seen in the midsubstance (Fig. A tear of the labrum can also occur in the back part of the socket. (B) Axillary radiograph of locked posterior glenohumeral dislocation. 1998 Sep;171(3):763-8. Patients often do not experience frank posterior dislocation events such as that with anterior shoulder instability and more commonly develop attritional lesions. Posterior labrum tear causes: Catching a heavy object . Open Access J Sports Med. The site is secure. Unlike the anterior labrum, rarely do we have a posterior dislocation of the shoulder. (A) Anteroposterior radiograph of severe glenoid dysplasia showing hypoplasia of the glenoid neck (blue arrow) and coracoid enlargement (orange star). eCollection 2019. 2000 Jun; 82(6):849-57. Future larger studies are needed to confirm these findings. This usually happens from an interior shoulder dislocation (a dislocation when the humeral head comes out of the front of the socket). However,patients with acute lesions often have joint effusion, which also distends the joint space, making the contrast administration unnecessary. HHS Vulnerability Disclosure, Help Magnetic resonance imaging, magnetic resonance arthrography and ultrasonography for assessing rotator cuff tears in people with shoulder pain for whom surgery is being considered. 10 A paralabral cyst indicates the presence of a labral tear. 1963 Dec. 43:1621-2. Harper and colleagues17 similarly developed a classification scheme with normal, mild, moderate, and severe glenoid dysplasia. There are a number of anatomical labral variants located between 11 and 3 o'clock, which can be mistaken for a SLAP tear: Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. With increased advancements in CT and MRI, more subtle forms of glenoid dysplasia have been recognized. Study the attachment of the IGHL at the humerus. AJR 2004; 183(2). The most common cause of a cyst of the shoulder is a labral tear. It is better visualized in ABER position.Articular cartilage lesions are best demonstrated with MR arthrography. 2009;192: 730-735. Posterior labral tear; < 15 decrease in affected shoulder internal rotation compared to contralateral shoulder . (A) Lightbulb sign demonstrating rounded appearance of the humeral head with a posterior glenohumeral dislocation. In a 20 year-old football player following acute injury, a reverse Bankart lesion is present. Crossref, Google Scholar; 73. This procedure greatly enhances the diagnostic accuracy by allowing tears . Reverse-bankart lesion: Also known as a posterior labral tear, this injury affects the rear and lower ends of the labrum. 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. Figure 17-5. Disclaimer, National Library of Medicine Advances in knowledge:: On a direct MR arthrographic image, a posterior capsular synovial fold may be a normal anatomic variant. This is not always the case. We have covered the tear itself and variants in earlier posts. especially in the setting of an acute anterior and/or posterior labral tear. In patients with glenoid deficiency or large impaction defects, osteotomies and osseous augmentation procedures may be required. 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). 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. Despite multiple studies documenting a clear significant association between subtle glenoid dysplasia and posterior labral tears with associated posterior shoulder instability, there is little evidence demonstrating an association with worse outcomes following surgical intervention. 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. The general approach will include an X-ray, ultrasound, MRI, or CT scan of the shoulder joint to assess the cause of the symptom. Dislocation of the long head of the biceps will inevitably result in rupture of part of the subscapularis tendon. It is present in 5% of the population. Type in at least one full word to see suggestions list. The labrum has the same effect on the shoulder as the rounded lip of a golf tee has to a golf ball. The labrum is the cartilage of the shoulder joint that encircles the socket to stabilize the shoulder. MRI is well recognized as an effective means to diagnose internal impingement of the shoulder. A shoulder labral tear injury can cause symptoms such as pain, a catching or locking sensation, decreased range of motion and joint instability. Locked posterior subluxation of the shoulder: diagnosis and treatment. That is, the labrum helps the shoulder from slipping out of its joint. -, Am J Sports Med. Study the superior biceps-labrum complex and look for sublabral recess or SLAP-tear. In many cases the axis of the supraspinatus tendon (arrowheads) is rotated more anteriorly compared to the axis of the muscle (yellow arrow). The anterior labrum and glenoid articular cartilage often demonstrate normal morphology one image superior to the . These normal variants will usually not mimick a Bankart-lesion, since it is located at the 3-6 o'clock position, where these normal variants do not occur. Clavert P. Glenoid Labrum Pathology. 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. Scroll through the images and notice the unattached labrum at the 12-3 o'clock position at the site of the sublabral foramen. The supraspinatus, infraspinatus and teres minor muscles and tendons are shown. Accessibility of the biceps in the bicipital groove. Figure 17-6. They did find that smaller glenoid width was a risk factor for failure.12. -, Stat Med. There are many labral variants. In part II we will discuss shoulder instability. They involve the superior glenoid labrum, where the long head of biceps tendon inserts. Notice the smooth borders unlike the margins of a SLAP-tear. Often, muscle wasting is seen clearly on MRI, showing atrophy of the muscle and build-up of fat. 2005;184: 984-988. There was a posterior labrum tear. Introduction. by Jaideep J. Iyengar, MD; Keith R. Burnett, MD; Wesley M. Nottage, MD American Journal of Sports Medicine 1994, 22:2:171-176. If there is a related partial thickness rotator cuff tear, there may also be lateral (on the side) pain. Tearing of the inferior glenohumeral ligament at the humeral attachment (blue arrow) is also evident. 12) or at the humeral attachment (Fig. (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. Tear of the posterior shoulder stabilizers after posterior dislocation: MR imaging and MR arthrographic findings with arthroscopic correlation. Findings compatible with posterior shoulder subluxation with an intramuscular tear of the teres minor, a posterior labral tear, and posterior capsular disruption. 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. Injuries isolated to labrum and capsule can often be successfully repaired with arthroscopic techniques including capsulolabral repair, capsular shift, and capsular shrinkage. 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. Normal Labral Anatomy. Fraying of the anterior section means some tearing of the surface with wispy threads emanating from that 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 . 1A: The ball (humerus) normally rests within the socket (glenoid) like a golf ball on a tee. The IGHL, labrum, and periosteum are stripped and medially displaced along the anterior neck of the scapula. Diagnostic criteria for both anterior and posterior labral tears present similarly. It should always be possible to trace the middle GHL upwards to the glenoid rim and downwards to the humerus. 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. Surg Clin North Am. 2011 May;196(5):1139-44. doi: 10.2214/AJR.08.1734. Study the labrum in the 3-6 o'clock position. Advanced MRI techniques of the shoulder joint: current applications in clinical practice. 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. In patients with traumatic posterior subluxation or dislocation, injuries to labrum, capsule, bone and rotator cuff may be found, and accurate diagnosis with MRI allows the most appropriate treatment pathway to be chosen. . Failure of one of the acromial ossification centers to fuse will result in an os acromiale. Baseball pitchers are shown to have a high prevalence. In type III there is a large sublabral recess. a painful feeling of clicking, popping or grinding in the shoulder during movement. Posterior labral periosteal sleeve avulsion injury (POLPSA) in a 19 year-old football player following acute injury. Posterior periosteum (arrowheads) is extensively stripped but remains attached to the posterior labrum. These tears include numerous variations designated by acronyms similar to those used for the more commonly seen anterior labral tears. The lesion is usually seen on the MRI. Images in the ABER position are obtained in an axial way 45 degrees off the coronal plane (figure). Radiology 2008; 248:185193. The supraspinatus tendon is the most important structure of the rotator cuff and subject to tendinopathy and tears. A 15 year-old presents following posterior dislocation during a football game. Background:The literature demonstrates a high prevalence of asymptomatic knee and hip findings on magnetic resonance imaging (MRI) in athletes. 2000;20 Spec No(suppl_1):S67-81. Shah AA, Butler RB, Fowler R, Higgins LD. 4A, green line), the torn 9:00 posterior labrum is opposite the 3:00 anterior labrum on an axial image (Fig. 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. Types of labral tears. The most common cause for a tear is after a shoulder dislocation when the most common site to tear is the anterior /inferior labrum. 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. Such injuries may be referred to as reverse HAGL (humeral avulsion of the glenohumeral ligament) or RHAGL lesions (Fig. 2009; 38(10):967-975. by Herold T, Bachthaler M, Hamer OW, et al. 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. 14). The rotator cuff is made of the tendons of subscapularis, supraspinatus, infraspinatus and teres minor muscle. If the arm is Diagnosis of a locked posterior humeral dislocation can be avoided by recognizing on the AP Grashey radiograph the presence of the lightbulb sign (Figure 17-3A), which is the humeral head taking on a rounded appearance similar to the shape of a lightbulb because of fixed internal rotation secondary to a posterior glenohumeral dislocation.4 In addition to recognizing the lightbulb sign on an AP Grashey radiograph, an axillary x-ray will confirm the diagnosis of a locked posterior dislocation (Figure 17-3B).
