Case contributed by Dr Andrew Dixon

Presentation

40 year old male in 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.
