Arthroscopic Tuberoplasty for a Malunited Greater Tuberosity Fracture: A Case Report.

Superior migration and malunion of a fractured greater tuberosity can lead to mechanical subacromial impingement with resultant ongoing pain and limitation of abduction. We describe such a case successfully treated with arthroscopic excision of the protruding portion of the greater tuberosity, with marked improvement in pain and range of movement. The greater tuberosity was exposed by elevating the supraspinatus tendon, which was reattached at the end of the procedure. This case, along with outcomes of similar techniques previously reported in literature suggest that arthroscopic excision of a superiorly malunited greater tuberosity is associated with good symptomatic outcome and preservation of rotator cuff function.
