Abstract
The gleno-humeral joint is considered the most commonly dislocated joint as it has a wide range of mobility. Shoulder instability is more common in
young active individuals. The glenoid is shallow providing little bony support
to prevent gleno-humeral instability. The glenoid labrum is a fibro-cartilage
located at the glenoid rim. which provides additional depth of 2 to 4 mm (50%)
and provides additional 1 crn ’ to the articular surface of the joint. The antcroinferior labrum removal decreases the height of glenoid by 80~(J and the
stability by 65%. Detecting the extent of a labral tear is important for planning
arthroscopic treatment. together with assessment of capsular and associated
structures.
The aim of this work is to assess the role of MR arthrography in
evaluation of labroligamentous lesions in patients with history of recurrent
shoulder dislocation and chronic shoulder pain.
This study has been carried out on thirty male patients. Their age
ranged from 20 to 45 years old with mean age of 27.233. Twenty patients
suffered from unilateral recurrent anterior shoulder dislocation (their age
ranged from 20-40 years old) with mean age of 26.25. nine patients suffered
from chronic shoulder pain (their age ranged from 22-45 years) with mean age
of 30.11 and onc patient with recurrent bilateral shoulder dislocation aged 21
wars old.
All patients were clinically evaluated. and then subjected to radiological
examination included conventional MRl and MR arthrography followed by
arthroscopic correlation in 21 patients and the other 9 patients either refused to be subjected for arthroscopy or were subjected for conservative treatment.
