  2. Superior labral anterior posterior (SLAP) tears are injuries of the glenoid labrum, and can often be confused with a sublabral sulcus on MRI
  3. Patient referred for 3T MRI Arthrography of the shoulder for suspicion of labral injury. Injection of Gadolinium based contrast agent allowed for visualization of the labrum and subsequent diagnosis of posterior tear
  4. This high variability in posterior labrum insertion increases the risk for misdiagnosis of posterior labral tears (31).The absence of bone or cuff lesions suggests a medialized variant labrum rather than a posterior labral tear (31)

The mean length (± SD) of posterior labral tear was 15.9 ± 1.7 mm, and a direct correlation was found between tear length and posterior humeral translation (r = -0.65; p = 0.002) summary 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. Diagnosis can be made clinically with positive posterior labral provocative tests and confirmed with MRI studies of the shoulder

Superior labral anterior posterior tear Radiology

The best tests available to make the diagnosis of a labral tear are magnetic resonance imaging (MRI) scans or a test called a CT-arthrogram (the latter is a CAT scan preceded by an arthrogram where dye is injected into the shoulder) MRI On conventional MR labral tears are best seen on fat-saturated fluid-sensitive sequences. On MR arthrography it is customary to combine T1, T1 FS and T2 FS sequences for further assessment. Imaging in three planes is advisable and additional orthogonal planes may be included in the protocol for a detailed assessment of the lesion suspected labrum tear is a very common finding on shoulder MRI and again the finding has to be understood based upon your symptoms and your history. To date no study has demonstrated that labrum tears lead to arthritis of the shoulder, so even if there is a labrum tear on the MRI you should not get too concerned until addressing it with your docto

Posterior Labrum Tear: 3T MRI Arthrogram Shoulde

  1. 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 inferiorly 15, in the region known as the posterior band of the inferior glenohumeral ligament
  2. The typical imaging finding of internal impingement in addition to posterosuperior rotator cuff and labral tears is remodeling of the posterior humeral head, consisting of subcortical cyst formation, bone marrow edema, and cortical flattening or depression (Fig 5) (55)
  3. There are two types of labral tears: SLAP tears and Bankart lesions. SLAP is an acronym that stands for 'Superior Labral tear from Anterior to Posterior'. SLAP tears start at the 12 o'clock position where the biceps anchor is located, which tears the labrum off the glenoid
  4. It is best to position the shoulder in neutral or external rotation for routine MRI. Internal rotation of the shoulder resulting in labral redundancy may also cause redundancy of the anteroinferior capsule that can conceal labral tears [ 26 ]
  5. Posterior labral tear The SLAP tear can continue posteriorly and can contribute to posterior shoulder pain. In some cases the posterior labral tear can form a flap valve and a cyst will develop. This cyst can also cause posterior shoulder pain, and when it is large, it can compress the suprascapular nerve, causing weakness of shoulder rotation

Imaging the Glenoid Labrum and Labral Tears RadioGraphic

Using an MRI arthrogram as a confirmatory test, they found the sensitivity of a posteroinferior labral tear to be 89.7% for a painful jerk and a specificity of 85% (2).They also found that a painful jerk test led to higher rates of failed nonoperative treatment (2) MRI diagnosis of labral tears is based on abnormalities in the signal intensity, morphology, and location (displacement) of the labrum. The labrum may be frayed, crushed, avulsed, or torn. Tears are classified by morphology, displaced or nondisplaced, and by location

Purpose: The purpose of this study was to evaluate the accuracy of magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) in diagnosing superior labral anterior-posterior (SLAP) lesions. We hypothesized that the accuracy of MRI and MRA was lower than previously reported. Methods: Between 2006 and 2008, 444 patients who had both shoulder arthroscopy and an MRI (non-contrast. Objective: Shoulder surgeons commonly intervene to repair unstable labral tears (tears that displace with patient movement). Surgeons can detect unstable tears at surgery. It is difficult to be certain if a tear is unstable from a static MR image. This study reports the comparative benefits of using unenhanced MRI and MR arthrography together to detect unstable labral tears

Regular MRI scans often miss labral tears. Certainly, if the labral tear has become symptomatic to lead to arthroscopic intervention, clear delineation of pathology is able to be performed with the arthroscope The labrum is the cartilage dish that sits between the ball and the socket configuration of the shoulder joint. The blunted configuration of the posterior part means some wear and tear and erosion. Fraying of the anterior section means some tearing of the surface with wispy threads emanating from tha Posterior labrum tear: This type of labrum tear is rare, but may be caused by repeated internal impingement, where the extreme extension and external rotation of the shoulder joint cause pinching of the bulged part of the arm bone against the lining of the shoulder joint cavity Posterior labrum tear, Posterior shoulder instability, Supraspinatus strain, Posterior deltoid strain. Treatment: As a result of the . athlete suffering from a complete shoulder dislocation and his demonstrated . loss of AROM he was referred to the team physician and an MRI was ordered. The MRI revealed a posterior labrum tear Findings at MRI include an excessively retroverted or hypoplastic glenoid, a detached posterior capsule and a posterior labral tear. The humeral head may be slightly more posteriorly placed than normal, and can occasionally demonstrate a notch defect anteriorly (reverse Hill-Sachs)

The glenoid labrum is a rim of cartilage attached to the glenoid rim. If the arm is shoulder joint (arthro MRI or arthro CT) • Examination under anesthesia followed by arthroscopy Some patients who dislocate their shoulder do Posterior Labral (Bankart) Repairs The same axial images on the left shoulder (Fig. 13.1f-i) show a similar posterior labral tear, this time accompanied with a more patulous posterior capsule, without an obvious capsule tear.This redundancy of the posterior capsule can also be observed on sagittal images (Fig. 13.1f-m), and the extension of the posterior labral detachment can be evaluated in a more medial sagittal image.

Posterior shoulder pain ; May have history of dislocation, more likely recurrent posterior subluxation (RPS) May be seen with seizures/ electrocution; Pain with jerk test +/- Kim test ; Pain with adduction and internal rotation; MRI with or without arthrogram is helpful to evaluate posterior labru PT (only saw once) suspected labral tear, suggested I see an orthopedic surgeon & get an MRI. Waited a year, saw him 2 weeks ago, MRI last week, appt last night confirmed posterior labral tear and that my shoulder is just loose in the socket in general The labrum itself is a special type of cartilage surrounding a socket, designed to cushion the joint and to increase the depth of the shoulder's glenoid socket that the ball of the humerus — or upper arm bone — lies within, thereby increasing overall joint stability. Posterior labral tears occur in the posterior, or rear, aspect of the labrum

Reverse Hill-Sachs and reverse Bankart lesion in a case of posterior instability. T1-weighted TSE axial magnetic resonance image reveals hemarthrosis, posterior glenohumeral dislocation and reverse Hill-Sachs lesion (straight arrow). There is associated posterior labral tear (reverse Bankart lesion), shown with a dashed arrow 1. INTRODUCTION. The superior labrum while playing an important role in stability of the shoulder has a high degree of variability in native anatomy, injury pattern, and adaptive anatomy. The location of the long head of the bicep origin has variability as well and can range from anterior to central to posterior locations along the superior rim.

The posterior band extends from the posterior labrum and glenoid rim to the posterior humerus and is usually part of the posterior capsule. B: An axial fat-suppressed T1-weighted MR arthrographic image shows the anterior band extending from the anterior-inferior labrum at the glenoid rim to the anatomic neck of the humerus A SLAP tear, or Superior Labrum from Anterior to Posterior lesion, usually occurs when there is a traumatic injury to the shoulder. As the name suggests, a SLAP tear occurs at the top (superior) of the labrum running from the front (anterior) to the back (posterior) of the joint cavity. The long head of the biceps brachii tendon (also called. Posterior Labral Tear (Lesion) This is a condition of the shoulder which usually affects younger people. It is most commonly caused by a fall onto the arm or a direct blow e.g. a rugby tackle. It is also seen in people who do a lot of throwing. The glenoid has a rim of tissue (the labrum) around its edge. At the top of this rim (12 o'clock. highly sensitive and specific for a posterior labral tear; kim test . arm positioned with shoulder abducted 90° and forward flexed 45° apply posteriorly and inferiorly directed force to shoulder through humerus; positive if patient experiences pain . highly sensitive and specific for posteroinferior labral tear ; Imaging: Radiographs. Labral tears of the shoulder are a common cause of shoulder pain, instability and sometimes catching or clicking. Over the last 30 years, as arthroscopy and the use of MRI imaging has advanced, the ability to diagnose labral tears as a cause of shoulder symptoms has improved

The shoulder is a tremendously mobile joint but prone to dislocations. Arthroscopy is regarded as the diagnostic gold standard but usually preceded by MR Arthrography ( MRA), a less invasive means for investigating associated lesions. Assessment of posterior labrum lesions can, however, be problematic • Labral tear - - complete absence of a portion of labrum, - displacement of labrum from glenoid rim or - linear area of increased signal intensity within the labrum on T2WI. Fig. T2 TSE axial section at the inferior head level: Bankart lesion is seen as a fragmented anterior inferior labrum with a defect at its base reaching the.

Magnetic resonance imaging (MRI) scans. This test can better show soft tissues like the labrum. 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 The two most common types of labral injuries in the shoulder are SLAP tears and Bankart tears (also known as Bankart lesions). SLAP tear. SLAP stands for superior labrum from anterior to posterior. This type of labral tear occurs where the labrum connects to the biceps tendon. Bankart tear About 1% of people have a congenital glenoid labrum variant where the anterosuperior labrum is absent. This variant is known as a Buford complex. Key Terms Labrum, SLAP lesion, Bankart lesion, rotator cuff, arthroscopy, torn biceps Skills. Categorize MRI findings of a torn labrum. Perform physical exam to identify labral pathology If this becomes significant, the result is posterior shoulder capsule tightness and a greater degree of glenohumeral internal rotation deficit (GIRD). Combined shoulder abduction and external rotation causes the biceps tendon to twist, increasing the stress placed on the tendon and its attachment, and thereby increasing the risk of a labral tear Andrews et al 1 first described tears of the superior aspect of the glenoid labrum in a series of overhead athletes in 1985. Injuries to the superior labrum and biceps tendon origin were further characterized and classified by Snyder et al 2 in 1990. Common to these lesions is detachment of the superior labrum from anterior to posterior, with or without involvement of the biceps tendon origin

If a tear of the labrum is suspected, magnetic resonance imaging (MRI) or computed tomography (CT) may be performed. However, a diagnosis of a labral tear can be confirmed through shoulder arthroscopy. Causes of Shoulder Labrum Tear. Shoulder labrum tears can occur from repetitive shoulder movements or from trauma What does the shoulder do while throwing? The shoulder internally rotates the humerus between 7000-8000 degrees per second. Throwing a baseball is the most violent motion in all of sports. MRI's reveal that more than 80% of shoulders in baseball players have tears in the labrum or fraying in the UCL. (This is why it is vital to go to a doctor.

Shoulder Injuries in the Overhead-Throwing Athlete

Bankart Tears: A Bankart tear occurs during a shoulder dislocation—when the shoulder comes out of joint, the labrum is torn, and the shoulder is more susceptible to future dislocations. Posterior Labral Tears: Posterior Labral tears occur when the rotator cuff and labrum are pinched together in the back of the shoulder MRI appearance: Fluid signal seen between the labrum and glenoid; Limited to above the equator and anterior to the biceps insertion; If the the signal between the labrum and glenoid extends into the anterior inferior labrum or posterior to the biceps insertion, it is a tear Posterior labrum tear: A rare type of tear, it can occur after injury to the back of the shoulder joint. SLAP tear or lesion: This type of labral tear occurs above the middle of the glenoid. SLAP stands for superior labrum, anterior to posterior Shoulder labral tears MRI 1. SHOULDER - LABRAL TEARS, VARAINTS. 2. The glenohumeral joint has the following supporting structures: Superiorly coracoacromial arch and coracoacromial ligament long head of the biceps tendon tendon of the supraspinatus muscle Anteriorly anterior labrum glenohumeral ligaments - SGHL, MGHL, IGHL (anterior band) subscapularis tendon Posteriorly posterior labrum.

Pitfalls in Shoulder MRI: Part 1—Normal Anatomy and

In MRI Findings in the majority of individuals, the superior labrum is meniscoid, resulting in a potential space between the deep surface of the labrum and the glenoid cartilage (sublabral recess. 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. In two patients (Case 1 and 3) along with labral cysts with tear, showed, enlarged capsule and positive drive through sign This can eventually wear out the labrum and cause fraying of the labrum without actually detaching it. This can also be known as a SLAP tear (Superior Labrum from Anterior to Posterior). A more extreme example is a fall onto the arm or shoulder, or an accident in which the ball of the shoulder actually pushes the labrum out of the socket Labral tears of the shoulder have been a particular focus of attention since the advent of the arthroscope, a small instrument that allows the orthopaedic surgeon to clearly see inside the shoulder joint and view the labrum, its environment, and any injuries that may have occurred.The arthroscope, in conjunction with anatomic dissections, history, physical examination, and symptoms has allowed. A systematic approach to diagnosis is essential to exclude life-threatening presentations of shoulder pain such as myocardial infarction or aortic dissection. Tears of the glenoid labrum fibrocartilage, also known as superior labral anterior to posterior (SLAP) lesions, are suspected clinically or noted on magnetic resonance (MRI) imaging

Diagnosing Posterior Labral Tears - Sports Medicine Revie

MRI was assessed for the presence of a labral tear, posterior glenoid cartilage abnormality, humeral head notching or cysts, and fraying or tear of the supraspinatus or infraspinatus tendons. Statistical analyses were performed using Student's t test, Fisher' My Posterior Labral Tear Thread. My original injury was in October of 2007. I was unracking 185 lbs on military press and had it slightly behind my head/back. As soon as it was unracked, I felt a sharp pain in my left shoulder and the weight fell. After sitting there for a few minutes, I still had some discomfort, but nothing too crazy An MRI scan is often done to diagnose a SLAP tear and other potential injuries to the muscles, tendons, ligaments, and cartilage in the shoulder. Because of the many overlapping and interwoven structures in the shoulder, it is possible for an MRI scan to miss a smaller tear. It is also possible for an MR arthrogram, or imaging to produce false. After a diagnostic MRI of a shoulder labrum tear, treatment consists of rest, anti-inflammatory medicine, and physical therapy to safely strengthen the muscles surrounding the injury. Learn more about shoulder labrum tear treatment and recovery, and when doctors consider shoulder labrum tear surgery Posterior shoulder instability tears occur in the back of the glenoid socket and are the least common type of labrum tear. These tears account for approximately 5-10% of all shoulder instability.

Pain in the back of the shoulder can indicate damage to the posterior labrum often corresponding to a posterior dislocation. Weakness and a catching sensation are other common symptoms of a labral tear. Diagnosis: After a thorough history and physical exam, x-rays are obtained to rule out any bony pathology. An MRI with contrast is helpful in. The glenoid labrum provides extra support for the shoulder joint, helping to keep it in place. A labral tear occurs when part of this ring is disrupted, frayed, or torn. Tears may lead to shoulder pain, an unstable shoulder joint, and, in severe cases, dislocation of the shoulder. Likewise, a shoulder dislocation can result in labral tears The sublabral recess does not usually extend to the posterior third of the superior labrum, and therefore, high signal intensity between the labrum and the glenoid in this region is considered to be consistent with a superior labral tear. Another MRI finding considered to be highly suggestive of a superior labral tear is laterally curved signal. Shoulder Instability and Labrum 2010 2 shoulder), usually the result of a subluxation or dislocation in the front of the shoulder: The next most common pattern of injury is a superior labral tear (at the top of the glenoid) which usually happens from repetitive overhead activities like baseball

Posterior labrum tear: These are rare and only makeup 5 to 10% of all shoulder injuries. Posterior labral tears can be caused by injuries to the back of the shoulder joint. Reverse Bankhart tear: Occurs when the damage is to the lower posterior quadrant of the glenoid socket Labral tear: See an experienced shoulder arthroscopist to assess clinical correlation w/ this MRI report.Basically it means you MAY have a labral( cartilage) tear of your shoulder in the 'back' portion ( posterior)of your glenoid( shoulder socket).the possible 'bony proliferation' may be a response to a long- standing labral tear.Clinical Correlation needed Labrum tears can be hard to diagnose because the cartilage lies deep in the shoulder, a complicated part of the anatomy. Your doctor will do a physical exam and may order imaging studies, including an MRI or a simple surgical procedure called arthroscopy.If you have what is known as a SLAP tear, which stands for superior labrum anterior posterior, it means the top part of your labrum is torn. The doctor may order the following imaging tests: X-rays: X-rays can alert doctors to problems with the hip bones, such as femoroacetabular impingement, or osteoarthritis, that may contribute to a labral tear and a painful hip. An MRI can show where a labral tear is, and how severe it is Bankart tear: The Bankart tear occurs near the front and bottom portion of your labrum, and frequently occurs when your shoulder dislocates.; SLAP tear: SLAP is an acronym for Superior Labrum, Anterior to Posterior.This is a tear in the upper portion of your labrum where your long biceps tendon attaches. Posterior labrum tear: This rare labrum tear occurs at the back of your shoulder labrum.

A SLAP tear is a tear in the labrum that covers the top part of the shoulder socket from front to back (Superior Labral tear from Anterior to Posterior). A SLAP tear occurs at the point where the long head of biceps tendon attaches. This type of tear occurs most commonly during falls on an outstretched arm Superior labrum anterior to posterior (SLAP) lesion tear surgery. A SLAP lesion tear surgery repairs a type of injury to the labrum, the cuff of cartilage that surrounds the shoulder joint and helps provide stability to the shoulder. The majority of SLAP repairs are performed arthroscopically. In this minimally invasive approach, the surgeon. Shoulder labrum tear causes. The specific cause underlying the various shoulder labrum tear (SLAP) presentations is multifactorial and remains a topic of debate and controversy 22).Regardless of the underlying cause, patients presenting with symptomatic shoulder labrum tear tears will commonly report the acute onset of deep shoulder pain accompanied by mechanical symptoms such as popping. Quadrilateral Space Syndrome. Lennard Funk. The quadrilateral space is located posterior and inferior to the glenohumeral joint and contains the axillary nerve and posterior humeral circumflex artery. The space is bounded superiorly by the teres minor muscle, inferiorly by the teres major muscle, medially by the long head of the triceps, and laterally by the humeral shaft

Magnetic resonance imaging revealed a posterior labral tear with a large, 3.1-cm multiloculated paralabral cyst, which extended into the spinoglenoid and suprascapular notches, likely resulting in significant compression of the suprascapular nerve and mild supraspinatus and infraspinatus edema. 1 - 3 The patient subsequently underwent. SLAP tears occur when the labrum is torn where the biceps tendons attach to the upper end of the humerus head and bend into the labrum (the anterior and posterior labrum attachment). The injury can be mild to severe. The best treatment for a SLAP tear is arthroscopic surgery. If you are having unrelieved shoulder pain and a decline in mobility.

The back of the labrum can be torn (posterior labral tear) in a posterior shoulder dislocation as well, but it more commonly tears secondary to multiple small injuries that jam the humeral head to the back (this classically happens to defensive linemen that try to block players all day long with the hands in the front). These anterior and. The appearance of a fraying in any cartilage on an imaging test such as MRI indicates damage since the labrum is made up of fibers, like fiberglass. There are timese when a surgeon will scope a joint with the intention to perform a repair or a resection, and find that there is either nothing wrong and he will just close up, and he could also.

The most common cause for a tear is after a shoulder dislocation when the most common site to tear is the anterior /inferior labrum. Posterior shoulder dislocations can result in posterior labral tears. Treatment of the labral tears in these scenarios involves treatment of the shoulder dislocation and stabilising the shoulder did mri on hip area. got these following results. 8 millimeter paralabral cyst along the posterior labrum with presumed labral tear. 1.9 x 1.6 x 3cm loculated cyst in right ovary and 1 cm of fibroid i read mor Four patients had arthroscopic confirmation of the posterior synovial fold. A higher percentage of posterior synovial folds were observed on shoulder MR arthrography (2.7%, 4/150) than on shoulder MRI (1.5%, 4/260). CONCLUSION: Although rare, the posterior synovial fold can be recognized and should not be confused with a posterior labral tear Posterior GLAD lesions consist of a cartilaginous injury and labral tear along the 7- to 9-o'clock positions of the glenoid (Figure 22). Kim Lesion. Kim lesions are characterized by a subtle marginal crack along the junction between the posteroinferior glenoid and posterior labrum while the labrum remains nondisplaced (Figure 23). These. An MRI scan is a special imaging test that uses magnetic waves to show the tissues of the shoulder in slices. The MRI scan shows soft tissues such as tendons and ligaments as well as bones. Labral tears may be seen using computed tomography (CT) scan and a special dye This is a critical concept that I'll review later, as fixing the shoulder instability is critical in healing a labral tear. The labrum can be torn or become degenerated (2). When the tear is in the upper part of the labrum, the area where the biceps tendon attaches to the lap of the socket is also commonly torn
