Abstract
Chronic displaced greater tuberosity avulsion fracture of the humerus causes severe retraction of the rotator cuff and resorption of the avulsion fragment. Many treatment options can be considered to solve this problem and return the patient to function. The arthroscopic technique is very challenging to achieve a reduction of the rotator cuff and fixation of greater tuberosity with minimized soft-tissue damage. This Technical Note describes a portal for arthroscopic-assisted reduction and fixation in severe retracted greater tuberosity avulsion fracture. The technique is easy to release and fix chronic displaced greater tuberosity and could avoid unnecessary open surgery.
