title: Perianchor radiolucency following PEEK suture anchor application associated with recurrent shoulder dislocation: a case report.
abstract: The authors describe a case of a 25 year old male who suffered recurrent shoulder dislocations after a symptom-free period following an initial arthroscopic shoulder stabilisation using PEEK suture anchors to repair the Bankart and SLAP lesions. The MRI and CT scans showed perianchor radiolucency around all of the previously placed PEEK suture anchors. It is believed that his recurrent shoulder instability was related to this radiological finding although the exact pathomechanism of the osteolysis is not clear. To our knowledge, this is the first reported case of perianchor radiolucency after the use of a PEEK suture anchor.
