Orthop J Sports Med. The chondral lesion is thought to arise secondary to impaction injury from the humeral head. Wirth MA, Lyons FR, Rockwood CA Jr. Hypoplasia of the glenoid: a review of sixteen patients. of the biceps in the bicipital groove. We have covered the tear itself and variants in earlier posts. in Radiology in 2008 examined 36 patients following acute traumatic shoulder dislocation and revealed full-thickness tears in 19% of patients and partial or full-thickness tears in 42%.17As would be expected, subscapularis tears were most common, but tears were also identified in the supraspinatus and the infraspinatus. . Which of the following is the next best step in management? De Maeseneer M, Van Roy F, Lenchik L et al. Notice the smooth borders unlike the margins of a SLAP-tear. It should always be possible to trace the middle GHL upwards to the glenoid rim and downwards to the humerus. In a 20 year-old football player following acute injury, a reverse Bankart lesion is present. Labral tears, such as a SLAP tear that cause a paralabral cyst, can occur due to trauma (dislocation), repetitive movement . the removal of the acromion distal to the synchondrosis may further destabilize the synchondrosis and allow for (SBQ16SM.25) Diagnostic arthroscopy revealed no significant glenohumeral articular defects. 12) or at the humeral attachment (Fig. 8600 Rockville Pike In Shoulder MR-Part I we will focus on the normal anatomy and the many anatomical variants that may simulate pathology. 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. Orthopedic surgeons will tell you that the labrum increases joint stability and serves as an anchor for ligaments and muscles. The axillary radiograph is also helpful in the traumatic scenario for identifying a posterior glenoid rim fracture or a reverse Hill-Sachs lesion. 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. Notice the rotator cuff interval with coracohumeral ligament. Does posterior labral tear require surgery? Imaging in three planes is advisable and additional orthogonal planes may be included in the protocol for a detailed assessment of the lesion. Treatment of the labral tears in these scenarios involves treatment of the shoulder dislocation and stabilising the shoulder. Figure 1. 2. Injuries isolated to labrum and capsule can often be successfully repaired with arthroscopic techniques including capsulolabral repair, capsular shift, and capsular shrinkage. Posterior ossification of the shoulder: the Bennett lesion. (10a) Ossification is seen along the posterior glenoid (arrows) in a professional baseball pitcher with a history of posterior instability. On conventional MR labral tears are best seen on fat-saturated fluid-sensitive sequences. While this certainly introduces vulnerability to injury, it also confers the advantage of broad range of motion. Such lesions are generally found in patients with atraumatic posterior instability. In addition to the discrepancy in posterior labral tear evaluations, radiologist 1 documented more pathology throughout the shoulder than radiologist 2. . The site is secure. where most labral tears are located. Additionally, a recent study by Meyer et al9 highlighted the importance of x-rays in evaluation of posterior shoulder instability. 2009;192: 730-735. A SLAP tear occurs both in front (anterior) and back (posterior) of this attachment point. The most common symptoms of a shoulder labrum tear can occur intermittently. Tendonitis of the long head of the biceps. Fluid undermines a tear of the posterior glenoid labrum (arrow) in a 42 year-old male with persistent posterior shoulder pain. On these axial images a Buford complex can be identified. Mild glenoid hypoplasia results in a rounded contour of the posterior glenoid with normal or only mildly thickened posterior labral tissue. Christensen GV, Smith KM, Kawakami J, Chalmers PN. Methods MR arthrograms of 97 patients with isolated posterior glenoid labral tears by arthroscopy and those of 96 age and gender-matched controls with intact posterior labra were reviewed by two blinded . . In part II we will discuss shoulder instability. Please enable it to take advantage of the complete set of features! 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. Notice superior labrum and attachment of the superior glenohumeral ligament. postulated that dislocations result in a 360 degree injury, with trauma to the anterior labrum, resulting in changes posteriorly, and vice versa. These are also called ganglion cysts of the shoulder. Capsule. Diagnosis . 2012;132(7):905-19. 1963 Dec. 43:1621-2. 2013 Sep 24;2013(9):CD009020. Fluid should not lie along both sides of the shoulder capsule. 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 . Orlando Orthopaedic Center's Dr. Randy S. Schwartzberg, a board certified orthopaedic surgeon specializing in Sports Medicine, discusses what's involved with. 2011 May;196(5):1139-44. doi: 10.2214/AJR.08.1734. The retracted end of the subscapularis (asterisk) is also visible compatible with a full thickness tear. It . They may extend into the tendon, involve the glenohumeral ligaments or extend into other quadrants of the labrum. 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. eCollection 2020 Aug. J Orthop. We hypothesize that this population will have fewer labral abnormalities than an athletic population. 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? In many cases the axis of the supraspinatus tendon (arrowheads) is rotated more anteriorly compared to the axis of the muscle (yellow arrow). The .gov means its official. Uncategorized. 8 Therefore, although Bennett lesions are typically not associated with . Oper Tech Sports Med 2016;24(3):181-188. Normal glenoid morphology is present. The findings are compatible with a posterior GLAD lesion (glenolabral articular disruption). Look for rim-rent tears of the supraspinatus tendon at the insertion of the anterior fibers. 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. The glenohumeral joint has a greater range of motion than any other joint in the body. Operative findings were used as the gold standard for posterior labral tear extension. However,patients with acute lesions often have joint effusion, which also distends the joint space, making the contrast administration unnecessary. Hottya GA, Tirman PF et al. This top area is also where the biceps tendon attaches to the labrum. Simoni P, Scarciolla L, Kreutz J, Meunier B, Beomonte Zobel B. J Sports Med Phys Fitness. government site. Study the attachment of the IGHL at the humerus. A 27-year-old male bodybuilder presents to the office with vague, deep shoulder pain and weakness with his bench press. The https:// ensures that you are connecting to the The first part of rehabilitation labral repair involves letting the labrum heal to the bone. Ultrasound will also show a shoulder ganglion cyst and the effects of muscle wasting. Normal anatomy. In type I there is no recess between the glenoid cartilage and the labrum. Chung CB, Sorenson S, Dwek JR and Resnick D. Humeral Avulsion of the Posterior Band of the Inferior Glenohumeral Ligament: MR Arthrography and Clinical Correlation in 17 Patients. Surgery may be required if the tear gets worse or does not improve after physical therapy. 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. Findings compatible with posterior shoulder subluxation with an intramuscular tear of the teres minor, a posterior labral tear, and posterior capsular disruption. He has full passive and active range of motion of the left shoulder that is symmetrical to his contralateral side. A common cause of a posterior labrum tear is repetitive microtrauma to the shoulder joint. 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). Lee SB, Kim KJ, ODriscoll SW, Morrey BF, An KN Dynamic glenohumeral stability provided by the rotator cuff muscles in the mid-range and end-range of motion. 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. Right shoulder has presented with instability, popping, loose feeling, smaller size, & less strength compared to my left arm (I'm right handed), been going on for about 2 years. In either case, the labrum can be torn off the bone. MRI is well recognized as an effective means to diagnose internal impingement of the shoulder. 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. Unable to process the form. The ligaments also aid in keeping the shoulder stable and in joint. The shoulder joint is the most unstable articulation in the entire human body. 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. It helps provide stability to the shoulder by . Adv Orthop. We hypothesized that the accuracy of MRI and MRA was lower than previously reported. A shoulder labral tear injury can cause symptoms such as pain, a catching or locking sensation, decreased range of motion and joint instability. The labrum has the same effect on the shoulder as the rounded lip of a golf tee has to a golf ball. It is present in 5% of the population.

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. Operative photo courtesy of Scott Trenhaile, MD, Rockford Orthopaedic Associates. These normal variants are all located in the 11-3 o'clock position. In previous studies, conventional MR sensitivity in detection of labral tears has ranged from 44% to 93% sensitivity compared with arthroscopy [1, 2].Two recent studies have assessed conventional MRI evaluation of the glenoid labrum using a 0.2-T extremity MR system. Glenoid labral tears are the injuries of the glenoid labrum and a possible cause of shoulder pain. 2006; 240(1):152-160. This ring of cartilage encompasses the outer rim of the glenoid to provide cushiony support around the head of the humerus. A displaced tear of the posteroinferior labrum is present, with a torn piece of periosteum (arrow) remaining attached to the posterior labrum. A posterior labral tear (reverse Bankart) is also present (arrowhead), and a bone bruise is seen within the anterior humeral head (asterisk). 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. 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. American Journal of Roentgenology. doi: 10.1002/14651858.CD009020.pub2. Tear of the posterior shoulder stabilizers after posterior dislocation: MR imaging and MR arthroscopic findings with arthroscopic correlation. AJR Am J Roentgenol. 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. Purpose: The management of these labrum injuries will depend on the classification, severity of the injury and the stability of the shoulder. Tear of the posterior shoulder stabilizers after posterior dislocation: MR imaging and MR arthrographic findings with arthroscopic correlation. 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. The posterior labrum is enlarged to replace the deficient glenoid rim. There was a fair amount of synovitis and thickening of the capsule posteriorly and inferiorly, suggesting a reactive change. Jun 23, 2021 by . Sensitivity was 66 %, and specificity was 77 %. Also. Low signal intensity blood clot (arrowhead) is present within the subscapularis recess. Dislocation of the long head of the biceps will inevitably result in rupture of part of the subscapularis tendon. A study in cadavers. (2a) The fat-suppressed proton density-weighted axial image reveals alignment of the humeral head posteriorly relative to the glenoid, with an impaction fracture of the humeral head articular surface (red arrow). In the shoulder, this pain is located posterior (behind) and superior (above). Increased glenoid retroversion increases the risk of posterior shoulder instability by 6 times. Measurement of Friedmans angle and posterior humeral head subluxation (yellow lines depict Friedmans angle; red line depicts percentage of posterior humeral head subluxation). A fold is more commonly occur in the posterosuperior and posteroinferior capsular portions. 2000 Jan;214(1):267-71 Am J Roentgenol. Study the superior biceps-labrum complex and look for sublabral recess or SLAP-tear. There is an ongoing debate on whether direct MR arthrography is superior to conventional MR in detecting labral tears. In more advanced cases of glenoid dysplasia, hypertrophic changes of the labrum and hyaline cartilage are pronounced. official website and that any information you provide is encrypted 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. An impaction fracture is also present at the posterior glenoid rim (blue arrow). 2017; 209: 544-551. 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. coracoacromial arch and coracoacromial ligament, glenohumeral ligaments - SGHL, MGHL, IGHL (anterior band). CT and MR Arthrography of the Normal and Pathologic Anterosuperior Labrum and Labral-Bicipital Complex. Epub 2011 Sep 9. The biceps looked stable. Arthroscopy. When the SLAP tears can cause pain and range-of-motion problems in the shoulder labrum, the biceps tendon or both. When you plan the coronal oblique series, it is best to focus on the axis of the supraspinatus tendon. I don't have pain generally at all. 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. They involve the superior glenoid labrum, where the long head of biceps tendon inserts. As a result, subtle articular-sided partial thickness tears will not lie apposed to the adjacent intact fibers of the remaining rotator cuff 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. 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. An area of capsular irregularity (arrow) is apparent as well. Look for impingement by the AC-joint. However, a study by Saupe et al. The glenoid labrum is a cartilage rim that attaches to the glenoid rim. This site needs JavaScript to work properly. a painful feeling of clicking, popping or grinding in the shoulder during movement. 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. The following algorithm has been previously proposed 25. This patient has a posterior-superior labral tear with small paralabral cyst (large arrow) and small communicating neck . McLaughlin, HL. Bennett GE: Shoulder and elbow lesions of the professional baseball pitcher. Indirect MR arthrography of the shoulder: use of abduction and external rotation to detect full- and partial-thickness tears of the supraspinatus tendon. MR arthrography has excellent accuracy in differentiating between SLAP lesions and anatomic variants. A Buford complex is a congenital labral variant. Surgical Management of Superior Labral Tears in Athletes: Focus on Biceps Tenodesis. Numerous capsular abnormalities have been described in patients with posterior glenohumeral instability. sports. Notice that the biceps tendon is attached at the 12 o'clock position. On MR arthrography, the mean posterior humeral translation was greater (6.2 mm 0.08; p = 0.019), posterior labral tears were longer (19.4 mm 1.7; p = 0.0008), and labrocapsular avulsion was more common (83%; p = 0.0001) in patients with posterior instability than in patients who had a posterior labral tear but a clinically stable shoulder. In that position the 3-6 o'clock region is imaged perpendicular. An official website of the United States government. Study the inferior labral-ligamentary complex. There was no subscapularis or rotator cuff tear and no superior labrum tear. The Bennett lesion (Fig. Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. 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. 2021 May 5;12:61-71. doi: 10.2147/OAJSM.S266226. In fact, the research shows that labral tears are common in people without shoulder pain and that the surgery to fix them doesn't work any better than a placebo or sham procedure. PMC Labral repair or resection is performed. 4B), which is what one would intuitively expect. Acute traumatic posterior shoulder dislocation: MR findings. Arthroscopic Posterior Labral Repair - Randy S. Schwartzberg, M.D. Usually it is an incidental finding and regarded as a normal variant. Posterior labral tearing was apparent on contiguous images (not shown). 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. The approach to surgery is dependent upon the type of injuries sustained by the patient, and the developmental or acquired alterations in anatomy that may be present. Insertion of the shoulder capsule onto the labrum or glenoid has been categorized previously according to a system by Mosley et al. Had axials been pre-scribed without regard to the glenoid clockface, then the 9:00 posterior posi- The authors found that specific acromial morphology on scapular-Y x-rays is significantly associated with the direction of glenohumeral instability. 2019 Nov 7;19:199-202. doi: 10.1016/j.jor.2019.10.015. 6). Posterior subluxation of the humeral head is also apparent. 2019 Dec 12;20(1):598. doi: 10.1186/s12891-019-2986-1. HHS Vulnerability Disclosure, Help Tearing of the inferior glenohumeral ligament at the humeral attachment (blue arrow) is also evident. Hottya GA, Tirman PF, Bost FW, Montgomery WH, Wolf EM, Genant HK. 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. -, Stat Med. Check for errors and try again. Examples include the reverse Bankart lesion, the POLPSA lesion, and the posterior GLAD lesion (sometimes referred to as a PLAD lesion) (Figs. (OBQ12.268) Biplanar radiographs should always be obtained when evaluating patients with suspected shoulder instability. complex injuries to the shoulder. If the arm is Clin Orthop Relat Res 1993 : 85-96. 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. What is Anterosuperior acetabular labrum? MR arthrography had a large number of false-positive readings in this study. MRI. In this post we look at Periosteal Stripping. 2000;20 Spec No(suppl_1):S67-81. Posterior subluxation of the humeral head is readily apparent. Bookshelf (B) Axillary radiograph demonstrating severe glenoid dysplasia with hypoplasia of the posterior glenoid and severe retroversion. The thickened middle GHL should not be confused with a displaced labrum. Shoulder Labral Tear Repair Surgery. The labrum is the cartilage of the shoulder joint that encircles the socket to stabilize the shoulder. 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.
