Notice the detatched labrum at the o'clock position on the sagittal MR-arthrogram. The shoulder almost always dislocates to anterior and inferior, because motion to superior is limited by the acromion, coracoid process and rotator cuff figure. Clinical presentation and follow-up of isolated SLAP lesions of the shoulder. Conclusion: Superior labral tears are diagnosed with high frequency using MRI in to year-old individuals with asymptomatic shoulders. First notice the Hill-Sachs defect indicating a prior anterior dislocation blue arrow. Given the findings of this study, it may be prudent to not order shoulder MRIs for patients between the ages of 45 and 60 years who have normal shoulder examinations. Results Twenty-six men and 27 women between the ages of 45 and 60 years participated in the study. Which treatment is used depends upon where the tear is located and how big it is. Thus, this radiologist counted posterior superior labral tears as superior and posterior labral tears.

  • However, the clinical and imaging diagnosis of labral tears can be challenging At the anterior and anterosuperior labrum, connecting fibers.

    The glenoid labrum, an important static stabilizer of the shoulder joint, has to discriminate from labral tears and is subject to specific patho. The shoulder labrum is a thick piece of tissue attached to the rim of the a labrum tear involves a physical examination and most likely an MRI, CT scan and​/or.
    Clockwise approach to labral pathology A Clockwise approach to the labrum is the easiest way to diagnose labral tears and to differentiate them from normal labral variants.

    Between andVogel et al 34 reported mean ages between 47 and 48 years annually in their analysis of a California database. On coronal images you want to make sure whether this is a variant like a labral recess or labral foramen or whether this is a SLAP.

    Making the diagnosis also takes some experience on the part of the surgeon, since the anatomy of the inside of the shoulder can be quite complex. Osseus Bankart Bankart lesions with an osseus fragment are common findings in patients with an anterior dislocation and are frequently seen on the x-rays or CT-scan.

    These two bones are connected by ligaments — tough tissues forming tethers that hold the bones in relationship to each other. The arrow points to the intact periosteum.

    This area is very complex and it is difficult to reliably get good pictures of this area with MRI.

    The anterior labrum is absent on the glenoid rim. Picture the shoulder joint as a beach ball on a dinner plate. The only exception to this rule is the reverse Bankart, which is the result of a posterior dislocation and injury to the inferoposterior labrum. However, the radiologists probably assumed that the MRIs they were reading were from symptomatic shoulders.

    Bankart Detachment of the anteroinferior labrum o'clock with complete tearing of the anterior scapular periosteum with or without an osseus fragment of the glenoid. Due to injury in this area where the biceps tendon attaches, the labrum also can get injured.

    There are two types of labral tears: SLAP tears and Bankart lesions.

    The shoulder almost always dislocates to anterior and inferior, because motion. The image on the left shows an absent anterosuperior labrum, which is. OBJECTIVE. MRI of the shoulder has been found to be sensitive and specific for detection of labral tears at T or lower field strength compared with.

    The ball of the shoulder can dislocate toward the front of the shoulder an anterior dislocation or it can go out the back of the shoulder called a posterior dislocation.

    A labrum tear can take several forms, and it is very easy to confuse these types. Thus, subjects who participated in such sports at younger ages were not detected. To clarify these possibilities, our study population would need to be evaluated with MRI scanners with magnet strengths other than 1. In the ABER position however there is tension on the antero-inferior labrum by the stretched anterior band of the inferior glenohumeral ligament and you have more chance to detect the tear.

    Findings regarding the labrum were not reported in either study.

    There are not many scientific studies that show that physical examination is reliable for making the diagnosis of a labral tear.

    Sometimes the labrum may have a large tear where a portion of the labrum gets into the joint and causes clicking and catching as the ball moves around in the socket. It is seen frequently in the shoulder as people get older over 40 years of age.
