EXP:

  • This question is tricky one. when you read the textbooks, it seems that the answer is anterior shoulder dislocation.
  • Yes, Hill sach’s lesion is seen in anterior shoulder dislocation. But, it is recurrent anterior shoulder dislocation.
  • Hill–sack lesion is a compression fracture of the posterolateral articular surface of humeral head. With the trauma of repeated dislocation, the humeral head is forced upon glenoid rim and the relatively soft bone of humoral head is crushed. The end result is an impression of the glenoid rim that is made on the humeral head.
