Reason: Outside Request: anterior instability left shoulder spastic quadriplegia; labral tear Evaluation is limited by metallic susceptibility artifact due to orthopedic hardware overlying the posterior aspect of the glenoid.ROTATOR CUFF: The supraspinatus and infraspinatus tendons appear intact. The teres minor and subscapularis tendons appear intact.SUPRASPINATUS OUTLET: There is trace fluid within the subacromial/subdeltoid bursa of doubtful clinical significance. The acromioclavicular joint is normal in appearance.GLENOHUMERAL JOINT AND GLENOID LABRUM: Evaluation of the glenoid and glenoid labrum is limited as described above. The anterior third of the glenoid appears deformed with slight angular depression of the articular surface, however, we are not certain to what degree this represents a true anatomic deformity or deformity related to the aforementioned metallic susceptibility artifact. The anterior inferior labrum appears enlarged which may represent a compensatory phenomenon. Although no gadolinium is seen separating the labrum from the underlying glenoid, the margins of the hypertrophied labrum are slightly irregular perhaps reflecting chronic degeneration. Furthermore, the articular cartilage of the anterior inferior glenoid is abnormally thickened and irregular with low signal intensity which also may represent a combination of degeneration and labral overgrowth. The posterior inferior labrum is difficult to evaluate due to metallic susceptibility artifact. The superior labrum appears intact. The glenohumeral joint capsule is patulous.BICEPS TENDON: The tendon of the long head of the biceps appears intact.
1. Limited study due to metallic susceptibility artifact from the patient's orthopedic hardware as described above.2. Deformity of the anterior inferior glenoid as described above which may reflect a peculiar dysplasia or the sequela of prior trauma/surgery. Although we see no fluid-filled tear of the labrum, the anterior inferior labrum appears thickened and irregular which may reflect a combination of chronic degeneration and scarring. Other findings as described above.
