What is the Aber position?
True ABER position (a) as an apprehension (or stress) test for orthopedists entails 90° of abduction and 90° of flexion of the arm at the shoulder. During ABER positioning for MR arthography of the shoulder, the patient usually has to make >90° of abduction of the arm to fit into the magnet (b).
What is a Sublabral recess shoulder?
A superior sublabral recess is located at the 12 o’clock position and represents a normal recess between the superior labrum and the cartilage of the glenoid cavity. A sublabral foramen is located at the 2 o’clock position and represents localized detachment of the labrum from the glenoid rim.
Does MRI show shoulder instability?
MRI and arthrographic studies are very accurate in showing chondral and labral injuries (such as Bankart lesion, ALPSA, GLAD and HAGL, as well as their counterparts in posterior instability).
Is a slap tear the same as a labrum tear?
A SLAP tear is also referred to as a labral tear, or a tear or lesion to the labrum. This injury tends to develop over time due to repetitive movements. It can also result from acute trauma or age.
What is a glad lesion in shoulder?
A GLAD (glenolabral articular disruption) lesion is caused by a forced adduction injury to the shoulder from an abducted and external rotated position; patients with GLAD lesions present with anterior shoulder pain as their chief complaint.
Does a Sublabral foramen require surgery?
Even though it is believed that a sublabral foramen (SF) requires no treatment, no objective data are available to establish whether this condition bears a relationship to anterior-inferior glenohumeral instability.
Is a Sublabral recess normal?
What does a labrum do?
The labrum is a thick tissue or type of cartilage that is attached to the rim of the socket and essentially forms a bumper that deepens the socket and helps keep the ball in place.
Does a shoulder MRI show the bicep?
MRIs can be used to give clear views of the shoulder. The shoulder is a complex joint, and it has a lot of different things that can go wrong. Injuries to the glenoid labrum, the rotator cuff, and the biceps tendon can all be diagnosed in good detail via an MRI.
Can shoulder instability Be Fixed?
To correct severe instability, open surgery is often necessary. An incision is made over the shoulder and the muscles are moved to gain access to the joint capsule, ligaments and labrum (Figure 6).
Where is a labrum tear located?
The shoulder labrum is a thick piece of tissue attached to the rim of the shoulder socket that helps keep the ball of the joint in place. The labrum can tear a few different ways: 1) completely off the bone, 2) within or along the edge of the labrum, or 3) where the bicep tendon attaches.
