In the clinic, we often encounter some patients who have pain and cannot lift their arms for a long time after the fracture of the greater tuberosity of the humerus, and the fracture is well aligned on the X-ray. What is the usual reason for this? This is due to a large humeral tuberosity fracture accompanied by a rotator cuff injury. How is it treated? Rotator cuff injuries usually require minimally invasive arthroscopic suturing. The incision is very small, about 0.5 cm, and recovery is much faster than with traditional surgery. It is also a very well established and effective minimally invasive procedure.
