Over the past years, several arthroscopic fixation procedures have been adopted for fractures of the greater tuberosity. Although they offer advantages over open approaches, especially for avulsion-type fixation, split-type fractures are usually treated with open reduction and internal fixation. However, suture constructs can result in a more reliable fixation system for multifragment or osteoporotic split-type fractures. Currently, the use of arthroscopic techniques in these more complex fractures is questionable due to inherent limitations of anatomic reduction and stability concerns. The authors report a technically simple and reproducible arthroscopic procedure based on anatomic, morphologic, and biomechanical concepts, which offers advantages over traditional open approaches or double-row arthroscopic techniques in the treatment of most split-type greater tuberosity fractures.
