[Nailing of metaphyseal fractures].

Nailing of metaphyseal fractures demands thorough preoperative planning. The trauma surgeon has to take the specific morphology of the fracture, the individual anatomy of the broken bone, and the design and characteristics of the selected implant into consideration. The fracture has to be precisely reduced and the reduction controlled during nail insertion. The reduction technique and reduction aids must be chosen preoperatively. The nail has to be introduced with care and brought to its correct and ideal position. Only after successful proximal and distal interlocking can the nail become the central weight bearing implant, which holds the fracture stable and reduced. In the following contribution, the specific problems of reduction and nail fixation of metaphyseal fractures of the proximal humerus, proximal and distal femur, and proximal and distal tibia together with the needed reduction and fixation aids are presented.
