Arthroscopic Repair of a Displaced Tuberosity Fragment After Proximal Humerus Locking Plate Fixation: A Case Report.

CASE: Locking plate fixation of proximal humerus fractures is known to have high complication rates. Even a technically well-performed surgery can be subject to loss of reduction, which can lead to an adverse functional outcome for the patient. In this case report, we describe a patient who underwent open reduction and internal fixation of a proximal humerus fracture complicated by delayed loss of reduction of a greater tuberosity fragment that was revised using arthroscopic techniques. CONCLUSION: Arthroscopic repair of displaced greater tuberosity fragments after failed locking plate fixation of proximal humerus fractures can lead to good functional outcomes at 1-year follow-up.
