Presentation
Shoulder pain. Past history of trauma.
Patient Data
Wedge-shaped bony defect measuring ~1 x 2.1 cm (width x length ) is noted in the posterolateral humeral head associated with adjacent marrow edema/bruise. Features suggestive for Hill-Sachs lesion.
The anterior inferior glenoid labrum is detached associated with glenoid rim fracture, suggestive of osseous Bankart lesion. No adjacent marrow edema is noted.
Abnormal intrasubstance increased signal is present along the course of supraspinatous tendon related to tendinosis.
Glenohumeral joint effusion is present.
A minimal fluid signal is noted at the Subacromial - subdeltoid bursae.
Acromion type II also is seen.
Case Discussion
Bony Bankart lesion with a bony defect at the posterosuperior aspect of the humeral head (Hill-Sachs deformity) may be seen in the setting of an anterior shoulder dislocation.
