Posterior shoulder dislocation with reverse Hill-Sachs and reverse Bankart lesions

Case contributed by Dr Andrew Dixon

Presentation

Motor car accident.

Patient Data

Age: 40
Gender: Male

Shoulder is now enlocated. 

Compression defect in the antero-medial humeral head (reverse Hill-Sachs lesion) and small chip fracture of the posterior glenoid (reverse Bankart lesion) are the sequelae of prior posterior shoulder dislocation. 

Case Discussion

Posterior shoulder dislocation demonstrated on initial plain films (trough line sign and loss of normal half moon overlap sign) . 

Post reduction plain films and CT reveal bony compression defect in the antero-medial humeral head (reverse Hill-Sachs lesion) and small chip fracture of the posterior glenoid (reverse Bankart lesion) which are common injuries associated with posterior shoulder dislocation.
