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. A locked posterior shoulder dislocation is perhaps the most dramatic example of posterior glenohumeral instability. the removal of the acromion distal to the synchondrosis may further destabilize the synchondrosis and allow for 4B), which is what one would intuitively expect. A study in cadavers. The labrum has the same effect on the shoulder as the rounded lip of a golf tee has to a golf ball. Glenoid labral tears are the injuries of the glenoid labrum and a possible cause of shoulder pain. 15,16). The most common symptoms of a shoulder labrum tear can occur intermittently. These normal variants are all located in the 11-3 o'clock position. Wuennemann F, Kintzel L, Zeifang F, Maier MW, Burkholder I, Weber MA, Kauczor HU, Rehnitz C. BMC Musculoskelet Disord. Future larger studies are needed to confirm these findings. . They did find that smaller glenoid width was a risk factor for failure.12. American Journal of Roentgenology. Also, it allows preoperative planning if a posterior bone block procedure is planned. 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. The labrum is a thick fibrous ring that surrounds the glenoid. Imaging of Posterior Shoulder Instability, Josef K. Eichinger, MD, FAOA and Joseph W. Galvin, DO, FAAOS. Also, although better visualized on MRA imaging, a hypertrophied posterior glenoid labrum is evident in patients with glenoid dysplasia (Figure 17-8). In a SLAP injury, the top (superior) part of the labrum is injured. In that position the 3-6 o'clock region is imaged perpendicular. 3. 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. Notice the biceps anchor. If the pre-test probability was above 90% or below 10% . Patients were included in the analysis if they had a posterior labral tear repair and had preoperative MRI or magnetic resonance arthrography (MRA). An official website of the United States government. Numerous labral abnormalities may be encountered in patients with posterior glenohumeral instability. As a result, subtle articular-sided partial thickness tears will not lie apposed to the adjacent intact fibers of the remaining rotator cuff Often, muscle wasting is seen clearly on MRI, showing atrophy of the muscle and build-up of fat. Bennett GE: Shoulder and elbow lesions of the professional baseball pitcher. A fold is more commonly occur in the posterosuperior and posteroinferior capsular portions. 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. Unable to load your collection due to an error, Unable to load your delegates due to an error. Conclusions: Surgical Management of Superior Labral Tears in Athletes: Focus on Biceps Tenodesis. Radiology. 6). Multidirectional shoulder instability (MDI) is a condition characterized by generalized instability of the shoulder in at least 2 planes of motion (anterior, posterior, or inferior) due to capsular redundancy. Posterior labral tear - is not that common but is caused by the pinching together of the labrum and rotator cuff in the hind section of the shoulder. 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? Rotator cuff tears in the context of posterior shoulder instability or dislocation were once thought to be rare. 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. Detection of partial-thickness supraspinatus tendon tears: is a single direct MR arthrography series in ABER position as accurate as conventional MR arthrography? While this certainly introduces vulnerability to injury, it also confers the advantage of broad range of motion. Figure 17-1. A common cause of a posterior labrum tear is repetitive microtrauma to the shoulder joint. What is Anterosuperior acetabular labrum? less common then antierior but 50% of traumatic posterior in ED missed 2-5% of all unsstable shoulders; RF- bony abnormality (glenoid retroversion or hypoplasia); ligamentous laxity 50% of cases are trauma; microtrauma -> labral tear, incomplete labral avulsion or erosion of posterior labrum -> gradual stretching of capsule & patulous posterior capsule; lineman/weight lifters/ over head . by Jaideep J. Iyengar, MD; Keith R. Burnett, MD; Wesley M. Nottage, MD Surg Clin North Am. 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 . The general approach will include an X-ray, ultrasound, MRI, or CT scan of the shoulder joint to assess the cause of the symptom. Uncategorized. The following algorithm has been previously proposed 25. Apart from that, CT is superior to MR in assessing bony structures, so this modality is helpful in detecting co-existing small glenoid rim fractures. 1963 Dec. 43:1621-2. Etiology, diagnosis, and treatment. A 22-year-old male wrestler presents to your clinic with complaints of deep left shoulder pain for the past 6 weeks. Please enable it to take advantage of the complete set of features! 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 . 12) or at the humeral attachment (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. 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. He has full passive and active range of motion of the left shoulder that is symmetrical to his contralateral side. Major NM, Browne J, Domzalski T, Cothran RL, Helms CA. A recess more than 3-5 mm is always abnormal and should be regarded as a SLAP-tear. Clin Orthop Relat Res 1993 : 85-96. Successful nonoperative treatment of posterior shoulder instability has had varying rates of success, between 16 and 70% of patients. 2000;20 Spec No(suppl_1):S67-81. 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. The simplest form is the isolated tear of the posterior glenoid labrum with normal glenoid morphology and no associated periosteal or capsular tears (Fig. Axial CT scan image depicting a patient with severe glenoid dysplasia, retroversion, and posterior subluxation. 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. 2020 Aug 27;8(8):2325967120941850. doi: 10.1177/2325967120941850.

A shoulder labral tear is an injury to this piece of cartilage, due to direct trauma, overuse, or instability. Philadelphia, Pa: Lea & Blanchard; 1822, Pollock RG, Bigliani LU. PMC In part II we will discuss shoulder instability. After addressing the disease prevalence, HPI and PMH, the pre-test probability likelihood of long head bicep pathology was appointed. Background:The literature demonstrates a high prevalence of asymptomatic knee and hip findings on magnetic resonance imaging (MRI) in athletes. Small to moderate glenohumeral joint effusion with synovitis and extension of fluid in the subcoracoid recess. The labrum is the cartilage dish that sits between the ball and the socket configuration of the shoulder joint. There are many labral variants. Look for excessive fluid in the subacromial bursa and for tears of the supraspinatus tendon. Diagnostic criteria for both anterior and posterior labral tears present similarly. 2006; 240(1):152-160. Dr. Ebraheim's educational animated video describes posterior labral tear - posterior shoulder instability. These are depicted in Figure 17-7. -, J Shoulder Elbow Surg. Notice smooth undersurface of infraspinatus tendon and normal anterior labrum. The most common cause of a cyst of the shoulder is a labral tear. Hottya GA, Tirman PF et al. Findings compatible with posterior shoulder subluxation with an intramuscular tear of the teres minor, a posterior labral tear, and posterior capsular disruption. 10 A paralabral cyst indicates the presence of a labral tear. A small chondral defect is present (arrowhead) adjacent to the free edge of the posterior labrum. Imaging of superior labral anterior to posterior (SLAP) tears of the shoulder. The https:// ensures that you are connecting to the Symptoms of a Shoulder Labrum Tear. These tears include numerous variations designated by acronyms similar to those used for the more commonly seen anterior labral tears. (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). 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. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Chmiel-Nowak M, Sheikh Y, Feger J, et al. Although x-ray findings are typically normal, they must be scrutinized to avoid errors of diagnosis such as missed posterior dislocations. A displaced tear of the posterior labrum (arrow) is present. 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. The blunted configuration of the posterior part means some wear and tear and erosion. In two patients (Case 1 and 3) along with labral cysts with tear, showed, enlarged capsule and positive drive through sign. Description. J Bone Joint Surg Am 1993; 75:1175-1184. (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. Operative findings were used as the gold standard for posterior labral tear extension. (OBQ11.152) The diagnostic value of magnetic resonance arthrography of the shoulder in detection and grading of SLAP lesions: comparison with arthroscopic findings. Normal anatomy. where most labral tears are located. The ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff. The most common cause for a tear is after a shoulder dislocation when the most common site to tear is the anterior /inferior labrum. Imaging in three planes is advisable and additional orthogonal planes may be included in the protocol for a detailed assessment of the lesion. 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. MeSH Orthopedic surgeons will tell you that the labrum increases joint stability and serves as an anchor for ligaments and muscles. American Journal of Sports Medicine 1994, 22:2:171-176. Labral tears, such as a SLAP tear that cause a paralabral cyst, can occur due to trauma (dislocation), repetitive movement . Look for rim-rent tears of the supraspinatus tendon at the insertion of the anterior fibers. The shoulder joint is a ball-and-socket joint that joins the upper arm's (humerus) bone with the shoulder blade (scapula). A shoulder labral tear injury can cause symptoms such as pain, a catching or locking sensation, decreased range of motion and joint instability. If the patient is unable to abduct the arm, then a Velpeau view is an alternate orthogonal radiograph (Figure 17-4). Tendonitis of the long head of the biceps. A displaced tear of the posteroinferior labrum is present, with a torn piece of periosteum (arrow) remaining attached to the posterior labrum. The management of these labrum injuries will depend on the classification, severity of the injury and the stability of the shoulder. We have covered the tear itself and variants in earlier posts. The glenohumeral joint has a greater range of motion than any other joint in the body. Hottya GA, Tirman PF, Bost FW, Montgomery WH, Wolf EM, Genant HK. [ 41] Findings are usually normal. The capsule is a broad ligament that surrounds and stabilizes the joint. Recurrent posterior shoulder instability: diagnosis and treatment. CT and MR Arthrography of the Normal and Pathologic Anterosuperior Labrum and Labral-Bicipital Complex. Look for HAGL-lesion (humeral avulsion of the glenohumeral ligament). The Bennett lesion (Fig. Images demonstrate a non-displaced tear involving the superficial anteroinferior labrum with associated injury to the adjacent cartilage 4.. There was a posterior labrum tear. (OBQ19.66) This usually happens from an interior shoulder dislocation (a dislocation when the humeral head comes out of the front of the socket). A sublabral foramen or sublabral hole is an unattached anterosuperior labrum at the 1-3 o'clock position. eCollection 2020 May-Jun. 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. Figure 1 is an artist's rendition of a normal shoulder joint as well as the trauma caused by shoulder instability depicted on MRI. Injury can also lead to a cyst that painfully compresses nerves in the shoulder. Such injuries may be referred to as reverse HAGL (humeral avulsion of the glenohumeral ligament) or RHAGL lesions (Fig. Sensitivity was 66 %, and specificity was 77 %. No Comments 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. 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. Fraying of the anterior section means some tearing of the surface with wispy threads emanating from that He has positive Kim and jerk tests and reproduction of symptoms with the shoulder in forward flexion, adduction, and internal rotation. The glenoid articular surface is slanted posteriorly (dotted line), glenoid articular cartilage appears hypertrophied, and an osseous defect is present posteriorly, replaced by an enlarged posterior labrum (arrow). Harper and colleagues, Arthroscopic Management of Posterior Instability, Radiographic and Advanced Imaging to Assess Anterior Glenohumeral Bone Loss, Management of In-Season Anterior Instability and Return-to-Play Outcomes, Decision Making in Surgical Treatment of Athletes With First-Time vs Recurrent Shoulder Instability, Management of the Aging Athlete With the Sequelae of Shoulder Instability, Instability in the Pediatric and Adolescent Athlete, History and Examination of Posterior Instability. The posterior labrum is stressed with an abducted arm and posterior force. When the labrum gets damaged or torn, it puts the shoulder at increased risk for looseness and dislocation. Advanced MRI techniques of the shoulder joint: current applications in clinical practice. Posterior labral tear; < 15 decrease in affected shoulder internal rotation compared to contralateral shoulder . Dislocation of the long head of the biceps will inevitably result in rupture of part of the subscapularis tendon. A posterior labrum tear is a rare type of shoulder labral tear that occurs in the back of the shoulder. Additionally, a recent study by Meyer et al9 highlighted the importance of x-rays in evaluation of posterior shoulder instability. Glenoid labrum (marked lig.) The labrum is a band of tough cartilage and connective tissue that lines the rim of the hip socket, or acetabulum. nor be effaced against the humeral head, and intra-articular contrast can enhance visualization of the tear (3). 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). Sports Health 2011 May, 3(3):253-263, Cooper A. The anterosuperior labrum is absent in the 1-3 o'clock position and the middle glenohumeral ligament is usually thickened. Federal government websites often end in .gov or .mil. The glenoid labrum is a cartilage rim that attaches to the glenoid rim. 1A: The ball (humerus) normally rests within the socket (glenoid) like a golf ball on a tee. Posterior labrum tear causes: Catching a heavy object . 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. In many cases the axis of the supraspinatus tendon (arrowheads) is rotated more anteriorly compared to the axis of the muscle (yellow arrow). Both tests may . sharing sensitive information, make sure youre on a federal De Maeseneer M, Van Roy F, Lenchik L et al. These images illustrate the differences between an sublabral recess and a SLAP-tear. The shoulder, because of its wide range of motion, is anatomically predisposed to instability, but the vast majority of shoulder instability is anterior, with posterior instability estimated to affect 2-10% of unstable shoulders.1Although anterior shoulder dislocations have been recognized since the dawn of medicine, the first medical description of posterior shoulder dislocation did not occur until 1822.2In modern times, posterior shoulder instability is still a commonly missed diagnosis, in part due to a decreased index of suspicion for the entity among many physicians. ADVERTISEMENT: Supporters see fewer/no ads. When the Sometimes at this level labral tears at the 3-6 o'clock position can be visualized. It should always be possible to trace the middle GHL upwards to the glenoid rim and downwards to the humerus. Reverse-bankart lesion: Also known as a posterior labral tear, this injury affects the rear and lower ends of the labrum. Bookshelf Posterior periosteum (arrowheads) is extensively stripped but remains attached to the posterior labrum. 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. 2012 Dec;52(6):622-30. 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). It is not healed. official website and that any information you provide is encrypted The posterior labrum is avulsed, and stripped scapular periosteum remains attached to the posterior labrum (arrowhead). In Shoulder MR-Part I we will focus on the normal anatomy and the many anatomical variants that may simulate pathology. In the event of a shoulder dislocation, the . (A) Anteroposterior radiograph of severe glenoid dysplasia showing hypoplasia of the glenoid neck (blue arrow) and coracoid enlargement (orange star). 1994 May; 3(3):173-90. An example of this position is pushing open a door with a straight arm. 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. Study the labrum in the 3-6 o'clock position. The labrum is the cartilage of the shoulder joint that encircles the socket to stabilize the shoulder. Since that time, other authors have expanded this classification to the current . Articular cartilage is maintained. 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. However,patients with acute lesions often have joint effusion, which also distends the joint space, making the contrast administration unnecessary. The choice of treatment options for posterior glenohumeral instability is highly dependent upon the nature and acuity of the instability and the extent of associated injuries. Imaging signs of posterior glenohumeral instability. The image shows the typical findings of a sublabral recess. Chang IY, Polster JM. We hypothesized that the accuracy of MRI and MRA was lower than previously reported. 11). Posterior labrum tear: This tear occurs at the back of the shoulder joint. 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. 2012 Sep;81(9):2343-7. doi: 10.1016/j.ejrad.2011.07.006. 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. A normal glenoid labrum has a laterally pointing edge and normal posterior labral morphology. The thickened middle GHL should not be confused with a displaced labrum. The authors found that specific acromial morphology on scapular-Y x-rays is significantly associated with the direction of glenohumeral instability. 2019 Oct 31;2019:9013935. doi: 10.1155/2019/9013935. MRI can rule out other causes of shoulder pain. 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. A hip (acetabular) labral tear is damage to cartilage and tissue in the hip socket. CT arthrography has been reported to have 97.3% accuracy for detecting Bankart lesions and 86.3% for SLAP lesions 4, which makes it comparable with MR arthrography and gives the possibility to examine the patients with contraindications to an MR examination. Objective To determine the prevalence of shoulder (specifically labral) abnormalities on MRI in a young non-athletic asymptomatic cohort. American Journal of Roentgenology. The abduction and external rotation of the arm releases tension on the cuff relative to the normal coronal view obtained with the arm in adduction. Low signal intensity blood clot (arrowhead) is present within the subscapularis recess. Non-contrast MRI had an accuracy of 85 %, sensitivity of 36 %, and a PPV of 13 %. Crossref, Google Scholar; 73. Clipboard, Search History, and several other advanced features are temporarily unavailable. Which of the following nerves was most likely injured during the procedure? In Shoulder MR-Part I we will focus on the normal anatomy and the many anatomical variants that may simulate pathology. The axial MR-images show an os acromiale with degenerative changes, i.e. On conventional MR labral tears are best seen on fat-saturated fluid-sensitive sequences. Notice rotator cuff muscles and look for atrophy. A posterior labral tear (reverse Bankart) is also present (arrowhead), and a bone bruise is seen within the anterior humeral head (asterisk). This type of shoulder labral tear can lead to intermittent symptoms and only occurs in 5-10% of shoulder labral tear patients. In all patients, posterior cartilage damage of type 3 to 4, classified according to Outerbridge, with a concomitant posterior labral tear was evident. In type I there is no recess between the glenoid cartilage and the labrum. The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 o'clock position, This can result in the damage to the anterior or front part of the labrum. Posterior subluxation of the humeral head is readily apparent. J Shoulder Elbow Surg. The shoulder joint is a ball and socket joint that connects the bone of the upper arm (humerus) with the shoulder blade (scapula). Diagnostic arthroscopy revealed no significant glenohumeral articular defects.
