摘要：
Disclosed is a device for fixing the proximal humerus, which comprises: a fixator (1), a main nail (2), an anti-rotation nail (3) and a locking nail (4), wherein the fixator (1) is set in the medullary canal of the proximal humerus, thereby matching the medullary canal of the proximal humerus； the upper end of the fixator (1) comprises a first contact part (11) and a second contact part (12)； the first contact part (11) is in contact with the head of the humerus and has a planar structure； the second contact part (12) is in contact with the greater tubercle of the humerus and has the shape of a bulge； the distal end of the lower end (13) of the fixator (1) has the shape of a bullet, the lower end (13) of the fixator (1) not being in contact with the medullary canal； the main nail (2) is used for fixing the humerus head and the first contact part (11)； the head of anti-rotation nail (3) enters the humerus head and the tail thereof is fixedly connected to the fixator (1)； and the locking nail (4) is arranged at the lower end (13) of the fixator (1) for fixedly connecting the fixator (1) and the humeral shaft. The fixing device has a good treatment effect for the fixing of severe comminuted fractures of the proximal humerus with or without association with shoulder dislocation, and has a low risk of surgery.
