Anterior dislocation of the shoulder associated with Bankart lesion in a patient with Poland's syndrome: a case report and review of the literature.

Poland's syndrome is a rare congenital entity characterized by unilateral partial or total hypoplasia of the major pectoralis muscle, breast and/or ipsilateral hand abnormalities. It has been reported in association with various structural and functional abnormalities. We report about a 23-year-old male kick-boxer with Poland's syndrome who presented in our department the history of two traumatic anterior shoulder dislocations due to boxing and self-reductions. Physical examination showed an instability of the left shoulder, and the MRI scans demonstrated a Bankart lesion. The patient had been treated with an arthroscopic Bankart repair; reattachment of the detached antero-inferior labrum down to the glenoid and repairing of the inferior gleno-humeral ligament complex. To our knowledge this is a first case report of a patient presenting with traumatic anterior shoulder dislocations due to kick-boxing associated with Poland's syndrome.
