Left Shoulder Labrum Tear Mri, Dr Nguyen Trong Anh Shoulder Instability Repair

Mr imaging diagnostic criteria for labral tear versus anatomic variant.

Heart with rising sun meaning. Radiologist will often say possible labrum tear or labrum tear cannot be ruled out a 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. The process of diagnosing a labral tear is complicated by the various pitfalls in imaging diagnosis often present in the superior labrum 1734 which can make this a challenging task for the radiologist. 2 direct mr arthrography distends the joint.

In the acute setting they are most frequently seen in. Unlike bankart lesions and alpsa lesions they are uncommonly 20 associated with shoulder instability 5. They can extend into the tendon involve the glenohumeral ligaments or extend into other quadrants of the labrum.

In the aber position the inferior glenohumeral ligament is stretched resulting in tension on the anteroinferior labrum allowing intra articular contrast to get between. Labral tears the abduction external rotation aber view is excellent for assessing the anteroinferior labrum at the 3 6 oclock position where most labral tears are located. Perthes lesion of the shoulder is one of the types of the anterior glenohumeral injury in which the anterior inferior labrum is torn and lifted from the edge of the glenoid 1 but still attached to the intact lifted periosteum from the anterior aspect of the glenoid.

When an mri with contrast is ordered contrast is injected into the vein while the arthrogram injects contrast directly into the joint under fluoroscopy guidance. Mr arthrography is employed for the detection of subtle rotator cuff tears or labral pathology in patients with a negative conventional mri the assessment of the postoperative shoulder and the demonstration of communication between the joint and extra articular pathology such as a paralabral cyst. 86 men and 60 women aged 21 to 70 mean 52 years underwent non contrast mri before arthroscopic operations on the glenohumeral joint.

Rule out labral tear to rule out a labral tear an mri arthrogram needs to be ordered not an mri with contrast. Slices were made in a transverse parasagittal and paracoronar orientation. A short video by dr.

Slap tears involve the superior glenoid labrum where the long head of biceps tendon inserts. However there are several mr imaging characteristics that can aid. Chris centeno that shows you how to understand your shoulder mri in three easy steps.

On images of the shoulder with the arm in a neutral position the torn labrum may be held in its normal anatomic position by the intact scapular periosteum which thereby prevents contrast media from entering the tear. To compare preoperative non contrast magnetic resonance imaging mri with arthroscopy findings in diagnosing labral and rotator cuff tears.
