[A new locking nail for proximal humerus fractures: the Telegraph nail, technique and preliminary results].
We present a new nail, the telegraph nail, designed for the treatment of proximal fractures of the humerus. This nail has a new locking system providing a self-stabilization of the cancelous screws inserted in small fragments. We discuss the surgical technique and present preliminary results. The anterolateral approach and nail insertion through the medial and well vascularized part of the cuff is described for simple fractures. With the cup and ball technique, this nail can also be used for complex fractures of the proximal humerus with three or four fragments and major displacement. With this method, the nail is inserted before reduction and locked in the distal humerus before fixation of the head and tuberosities around the head once the targeting device removed. We report results for the first 64 nails inserted in our unit during the first year (1998-1999). Outcome was assessed at 11 months mean follow-up using the Constant score. Outcome was favorable, including in patients with complex fractures involving 3 or 4 separate displaced fragments. Besides providing an anatomically stable reconstruction, the telegraph nail has the advantage of allowing early mobilization of the shoulder joint. This method is a useful alternative to prosthetic reconstruction for traumatic fractures of the proximal humerus.
