Anterior dislocation of right shoulder
(33-year-old male) Anterior dislocation of right shoulder. Right wrist pain.
Long- and short-axis fat- and water-weighted images were performed; 1.5T High Field Oval.
Proximal biceps long head tendon intact. Thin posterosuperior labral tear. Anteroinferior labral and adjacent periosteal tear present consistent with Bankart lesion. Small area of high-grade bone contusion in the nearby anteroinferior glenoid present. Inferior glenoid and humeral neck attachments of the axillary capsule / IGHL are torn. Floating IGHL or anteroinferior glenoid labroligamentous separation. Prominent surrounding soft tissue swelling. Contusion/strain of the nearby teres major muscle. Subscapularis recess distention.
Hypertrophic strain/contusion of the distal supra and infraspinatus tendons present. There is an approximately 1.6 x 1 x 1mm interstitial tear at the distal supraspinatus at the footprint. Prominent concavity/impaction fracture of the posterosuperior humeral head present with large surrounding area of high-grade bone contusion and trabecular microfracture. High-grade bone contusion extends to the humeral neck.
Teres minor tendon intact. Mild distal subscapularis tendon strain present. Low-grade strain/contusion of the deltoid muscle and distal/lateral trapezius muscle present.
- Anterior shoulder dislocation with Bankart lesion and large Hill-Sachs impaction fracture. High-grade bone contusion and trabecular microfracture in the humeral head and neck
- Hypertrophic strain / contusion of the distal supra and infraspinatus tendons. Tiny 1.6 x 1 x 1mm interstitial tear of the distal supraspinatus at the footprint
- Tears / detachment of the axillary capsule both from the humeral neck and inferior glenoid. Floating IGHL or anteroinferior glenoid labroligamentous separation
