Arthroscopic Parachute Technique for Split-type Greater Tuberosity Fractures.

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.
