Kim lesion (shoulder)

Kim lesions are superficial tears between the posterior glenoid labrum and glenoid articular cartilage without labral detachment. Failure to identify and treat this lesion may lead to permanent posterior instability. 

It typically results from a postero-inferiorly directed force on the labrum with a deep and/or intrasubstance incomplete detachment of the posteroinferior labrum from the glenoid accompanied by a separate superficial tear between the posteroinferior labrum and articular cartilage.

  • flattening or incomplete avulsion of posterior labrum
  • normal relation of glenoid cartilage and posterior labrum
  • glenoid retroversion

May shows a thin collection of contrast material entering a cleft between the posteroinferior glenoid and the glenoid labrum. There is no displacement of the labrum. 

It is named after S.H Kim who first described reported the condition on literature in 2004 2.
