posterior labral tear shoulder mri

Once thought to be a relatively rare entity, a study by Harper et al. Results: Injuries isolated to labrum and capsule can often be successfully repaired with arthroscopic techniques including capsulolabral repair, capsular shift, and capsular shrinkage. Careers. A displaced tear of the posteroinferior labrum is present, with a torn piece of periosteum (arrow) remaining attached to the posterior labrum. When you plan the coronal oblique series, it is best to focus on the axis of the supraspinatus tendon. In that position the 3-6 o'clock region is imaged perpendicular. -, Am J Sports Med. He has positive Kim and jerk tests and reproduction of symptoms with the shoulder in forward flexion, adduction, and internal rotation. 11). The insertion has a variable range. Diagnosis . The biceps tendon is medially dislocated (short arrow). The fibers of the subscapularis tendon hold the biceps tendon within its groove. Major NM, Browne J, Domzalski T, Cothran RL, Helms CA. In a 34 year-old male following an acute subluxation event, a tear is present along the base of the posterior labrum with edema and irregularity noted at adjacent posterior periosteum (arrow). In our retrospective study of 444 patients, sensitivity, specificity, and accuracy were all lower than previously reported in the literature for diagnosing SLAP lesions. ALPSA lesions are . Etiology, diagnosis, and treatment. 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. 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 . 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. The general approach will include an X-ray, ultrasound, MRI, or CT scan of the shoulder joint to assess the cause of the symptom. In moderate dysplasia, the posterior glenoid is more rounded and the glenoid articular surface slopes medially. Study the inferior labral-ligamentary complex. (OBQ12.268) (10a) Ossification is seen along the posterior glenoid (arrows) in a professional baseball pitcher with a history of posterior instability. 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. Surgical treatment: arthroscopic debridement . Type 1 shoulder labrum tear. 7-9). J Am Med Assoc 117: 510-514, 1941. 14). Arch Orthop Trauma Surg. Posterior Labral Tear. Posterior labral tearing was apparent on contiguous images (not shown). A Meta-Analysis of the Diagnostic Test Accuracy of MRA and MRI for the Detection of Glenoid Labral Injury. An arthroscopic examination confirmed the MRI findings and showed multiloculated cysts in the inferior labrum, mostly between 5 o'clock to 7 o'clock positions with labral tear. eCollection 2020 Aug. J Orthop. where most labral tears are located. In either case, the labrum can be torn off the bone. MR arthrography had an accuracy of 69 %, sensitivity of 80 %, and a PPV of 29 %. Crossref, Google Scholar; 73. Pathomechanics and Magnetic Resonance Imaging of the Thrower's Shoulder. sports. Philadelphia, Pa: Lea & Blanchard; 1822, Pollock RG, Bigliani LU. Objective The purpose of this study is to evaluate the accuracy of MR arthrography in detecting isolated posterior glenoid labral injuries using arthroscopy as the reference standard. 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. What are the findings? Shah AA, Butler RB, Fowler R, Higgins LD. Accessibility . The retracted end of the subscapularis (asterisk) is also visible compatible with a full thickness tear. 2012;132(7):905-19. Hottya GA, Tirman PF et al. Posterior shoulder dislocations can result in posterior labral tears. The labrum is cartilage tissue that holds the "ball" (humeral head) in the "socket" (glenoid) of your shoulder. HHS Vulnerability Disclosure, Help The small size of the glenoid fossa and the relative laxity of the joint capsule renders the joint relatively unstable and prone to subluxation and dislocation. MRI of the shoulder has been found to be accurate in the diagnosis of labral tears. . (A) Lightbulb sign demonstrating rounded appearance of the humeral head with a posterior glenohumeral dislocation. SLAP tears can cause pain and range-of-motion problems in the shoulder labrum, the biceps tendon or both. [ 41] Findings are usually normal. 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. Had axials been pre-scribed without regard to the glenoid clockface, then the 9:00 posterior posi- His examination is somewhat difficult due to his large size, but no significant abnormal findings are noted. MRI of the shoulder second edition Sports Health 2011 May, 3(3):253-263, Cooper A. Increased glenoid retroversion increases the risk of posterior shoulder instability by 6 times. Chang IY, Polster JM. 1998 Apr 30;17(8):857-72 Successful nonoperative treatment of posterior shoulder instability has had varying rates of success, between 16 and 70% of patients. When the labrum gets damaged or torn, it puts the shoulder at increased risk for looseness and dislocation. These shoulder MRI findings in middle-aged populations emphasize the need for supporting clinical judgment when making treatment decisions for this patient population. Articular cartilage is maintained. sharing sensitive information, make sure youre on a federal Look for variants like the Buford complex. 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). This is a common injury for athletes such as baseball pitchers and . 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. However,patients with acute lesions often have joint effusion, which also distends the joint space, making the contrast administration unnecessary. Radiology. 6). Notice that the biceps tendon is attached at the 12 o'clock position. Clinical History: A 72 year-old male presents with severe left shoulder pain and limited motion following a fall 10 days earlier. Such lesions are generally found in patients with atraumatic posterior instability. AJR 2004; 183(2). Surg Clin North Am. Numerous labral abnormalities may be encountered in patients with posterior glenohumeral instability. 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. The chondral lesion is thought to arise secondary to impaction injury from the humeral head. The most common cause for a tear is after a shoulder dislocation when the most common site to tear is the anterior /inferior labrum. 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. Surgical Management of Superior Labral Tears in Athletes: Focus on Biceps Tenodesis. Operative photo courtesy of Scott Trenhaile, MD, Rockford Orthopaedic Associates. The os acromiale may cause impingement because if it is unstable, it may be pulled inferiorly during abduction by the deltoid, which attaches here. Posterior instability of the shoulder can vary from minor symptoms and findings to dramatic events resulting in extensive, complex injuries to the shoulder. Description. Insertion of the shoulder capsule onto the labrum or glenoid has been categorized previously according to a system by Mosley et al. Wirth MA, Lyons FR, Rockwood CA Jr. Hypoplasia of the glenoid: a review of sixteen patients. Tear of the posterior shoulder stabilizers after posterior dislocation: MR imaging and MR arthroscopic 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. This sublabral recess can be difficult to distinguish from a SLAP-tear or a sublabral foramen. MeSH Please enable it to take advantage of the complete set of features! Figure 1 is an artist's rendition of a normal shoulder joint as well as the trauma caused by shoulder instability depicted on MRI. Some types of the posterior synovial fold can mimic a posterior labral tear in conventional MRI. 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. Broadly, clinical unidirectional . Radiographs are normal, and an MRI arthrogram is shown in Figure A. If this appearance is present, a capsular tear should be strongly suspected (Fig. De Maeseneer M, Van Roy F, Lenchik L et al. These are depicted in Figure 17-7. To provide the highest quality clinical and technology services to customers and patients, in the spirit of continuous improvement and innovation. 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. An official website of the United States government. J Shoulder Elbow Surg. True anteroposterior or Grashey x-ray. The supraspinatus tendon is the most important structure of the rotator cuff and subject to tendinopathy and tears. 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. 4A, green line), the torn 9:00 posterior labrum is opposite the 3:00 anterior labrum on an axial image (Fig. posterior labral tear surgery. 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. In a SLAP injury, the top (superior) part of the labrum is injured. If the patient is unable to abduct the arm, then a Velpeau view is an alternate orthogonal radiograph (Figure 17-4). (B) Axillary radiograph demonstrating severe glenoid dysplasia with hypoplasia of the posterior glenoid and severe retroversion. These are also called ganglion cysts of the shoulder. Posterior labrum tear: This tear occurs at the back of the shoulder joint. What is your diagnosis? Am J Roentgenol. Although x-ray findings are typically normal, they must be scrutinized to avoid errors of diagnosis such as missed posterior dislocations. Since that time, other authors have expanded this classification to the current . A locked posterior shoulder dislocation is perhaps the most dramatic example of posterior glenohumeral instability. Tearing of the inferior glenohumeral ligament at the humeral attachment (blue arrow) is also evident. 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. A posterior labrum tear is a rare type of shoulder labral tear that occurs in the back of the shoulder. 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. Not All SLAPs Are Created Equal: A Comparison of Patients with Planned and Incidental SLAP Repair Procedures. The labrum is a thick fibrous ring that surrounds the glenoid. Biplanar radiographs should always be obtained when evaluating patients with suspected shoulder instability. Unable to load your collection due to an error, Unable to load your delegates due to an error. 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. Fluid distends the joint and only lies along the inner margin of the joint capsule (arrowheads). Figure 17-5. FOIA A normal glenoid labrum has a laterally pointing edge and normal posterior labral morphology. An anteroposterior (AP) Grashey image (also known as a true AP view because the beam is oriented perpendicular to the scapula, which is oriented 30 degrees anterior to the coronal plane) (Figure 17-1) along with an axillary x-ray (Figure 17-2), are the minimum radiographs that should be obtained. There was a posterior labrum tear. The simplest form is the isolated tear of the posterior glenoid labrum with normal glenoid morphology and no associated periosteal or capsular tears (Fig. Following a posterior subluxation event, a fat-suppressed T2-weighted coronal image in this 52 year-old male reveals focal edema and irregularity at the humeral attachment of the posterior band of the inferior glenohumeral ligament (arrow), compatible with a partial tear. 1994 May; 3(3):173-90. Follow me on twitter:https://twitter.com/#!/DrEbr. Diagnosis can be made clinically with positive posterior labral provocative tests and confirmed with MRI studies of the shoulder. Examples include the reverse Bankart lesion, the POLPSA lesion, and the posterior GLAD lesion (sometimes referred to as a PLAD lesion) (Figs. Types of labral tears. Study the labrum in the 3-6 o'clock position. Dislocation of the long head of the biceps will inevitably result in rupture of part of the subscapularis tendon. Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. 8 Therefore, although Bennett lesions are typically not associated with . Fluid should not lie along both sides of the shoulder capsule. Imaging in three planes is advisable and additional orthogonal planes may be included in the protocol for a detailed assessment of the lesion. 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. His pain is aggravated when grappling with other wrestlers and when performing push-ups. 4. In the shoulder, this pain is located posterior (behind) and superior (above). 2012 Dec;52(6):622-30. The radiologic diagnosis and surgical evaluation were compared to determine the accuracy of diagnosing a SLAP lesion by MRI. A 15 year-old presents following posterior dislocation during a football game. 2019 Dec 12;20(1):598. doi: 10.1186/s12891-019-2986-1. 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. Probing of the posterior labrum is needed to rule out a subtle Kim lesion. Posterior shoulder instability is a relatively rare phenomenon compared to anterior instability, comprising only 5-10% of all shoulder instability. In type I there is no recess between the glenoid cartilage and the labrum. Smith T, Drew B, Toms A. Glenoid labral tears are the injuries of the glenoid labrum and a possible cause of shoulder pain. 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? A recess more than 3-5 mm is always abnormal and should be regarded as a SLAP-tear. American Journal of Sports Medicine 1994, 22:2:171-176. (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). Operative findings were used as the gold standard for posterior labral tear extension. Rotator cuff tears (B) Axillary radiograph of locked posterior glenohumeral dislocation. In part III we will focus on impingement and rotator cuff tears. 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. It is seen in 11% of individuals. eCollection 2021. Saupe N, White LM, Bleakney R, et al. 2013 Sep 24;2013(9):CD009020. The labrum in the shoulder joint is a vital component that helps stabilize the humerus and shoulder blade during movement. Study the superior biceps-labrum complex and look for sublabral recess or SLAP-tear. Posterior ossification of the shoulder: the Bennett lesion. MRI is well recognized as an effective means to diagnose internal impingement of the shoulder. Open Access J Sports Med. -, BMJ. AJR Am J Roentgenol. The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 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. Check for errors and try again. nor be effaced against the humeral head, and intra-articular contrast can enhance visualization of the tear (3). Radiographics. ORTHOPEDICS August 2010;33(8):562. by Schreinemachers SA, van der Hulst VP, Willems WJ, Bipat S, van der Woude HJ. Additionally, a recent study by Meyer et al9 highlighted the importance of x-rays in evaluation of posterior shoulder instability. Radiology. It cushions the joint of the hip bone, preventing the bones from directly rubbing against each other. Which of the following is the most likely etiology of his complaints? Clavert P. Glenoid Labrum Pathology. A study in cadavers. While this certainly introduces vulnerability to injury, it also confers the advantage of broad range of motion. A posterior labral tear (reverse Bankart) is also present (arrowhead), and a bone bruise is seen within the anterior humeral head (asterisk). The blunted configuration of the posterior part means some wear and tear and erosion. 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. scan or magnetic resonance imaging (MRI) scan may be ordered for a glenoid labrum tear diagnosis. In part II we will discuss shoulder instability. Notice the fibers of the inferior GHL. To make a tear in the labrum show up more clearly on the MRI, a dye may be injected into your shoulder before the scan is taken. Look for HAGL-lesion (humeral avulsion of the glenohumeral ligament). Hottya GA, Tirman PF, Bost FW, Montgomery WH, Wolf EM, Genant HK. Hill Sachs lesions are only seen at the level of the coracoid. a painful feeling of clicking, popping or grinding in the shoulder during movement. 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. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Chmiel-Nowak M, Sheikh Y, Feger J, et al. Federal government websites often end in .gov or .mil. It is, however, becoming more frequently recognized, particularly in athletes such as football players and weightlifters, in which posterior glenohumeral instability has achieved increased awareness.3 As McLaughlin stated in 19634, the clinical diagnosis is clear-cut and unmistakable, but only when the posterior subluxation is suspected. 1985 Sep-Oct;13(5):337-41 The labrum is the cartilage of the shoulder joint that encircles the socket to stabilize the shoulder. Overall, an MRI scan will clearly show the ganglion cyst in the shoulder and whether it compresses the nerve. Clin Orthop Relat Res 1993 : 85-96. Christensen GV, Smith KM, Kawakami J, Chalmers PN.
