30,000 TELEGRAPH nails have been implanted in the last 10 years! This is the most commonly used nail in France, and the first nail to propose self-stability locking. A precise and simple instrument set that makes it possible to obtain a reproducible technique. The TELEGRAPH nail remains the least voluminous material proposed for anterograde nailing of the humerus. There are two versions : a short nail, for proximal fractures ; a long nail, for diaphyseal fractures. Indications Diaphyseal fracture The diaphysis is separated into 2 parts > Long TELEGRAPH nail Extra-articular fracture with 2 or 3 fragments This situation is typical of 60% of cases. Recommended technique: percutaneous > Short TELEGRAPH nail Articular fracture >> Valgus impacted articular fractures : Standard indication Recommended technique: Standard > Short TELEGRAPH nail >> Articular fractures with 3 or 4 fragments, disimpacted or even dislocated : Recommended technique: Discussion on whether to implant a nail or a prosthesis anatomical or reverse > Short TELEGRAPH nail or Shoulder prosthesis
