INTRODUCTION:The glenohumeral joint is a synovial-lined ballin-socket joint that has the greatest range of motion of any
joint in the human body. It is the most commonly
dislocated joint.. Glenohumeral stability is provided by
dynamic and static "restraints". The glenoid labrum is
commonly torn or avulsed when excessive force is applied
to a glenohumeral ligament or the long head biceps.
METHODOLOGY:Patients with suspected glenohumeral
instability where referred to Dept of Radio-Diagnosis, SRM
MCH & were subjected to MRI on a 1.5 Tesla SEIMENS.
Various injuries were detected, characterized and
classified.
RESULTS:Anterior instability is the most common type of shoulder
instability. It is associated with a Bankart lesion and its variants and
abnormalities of the anterior band of the inferior glenohumeral
ligament, whereas posterior instability is associated with reverse
Bankart and reverse Hill-Sachs lesions. Depending on the etiology and
age of the patient, there may be associated injuries. This poster reveals
the relevant anatomy in brief and describes the MRI findings in each
type, with the imaging features of the common abnormalities.
CONCLUSION:Injuries to the glenohumeral ligaments, labrum, and biceps
labral complex are often the cause. High spatial resolution, excellent
image contrast, and multiplanar capabilities make MRI an excellent
tool in the evaluation of the labrum. MR allows accurate depiction of
the size and location of labral tears and their associated capsular and
glenohumeral ligament injuries. Normal variants that can mimic
pathology are well depicted on MR imaging.
