?One of this implant favorite utilization features is the distal locking security, since inside the technique use, practical and simple, a constant symmetry is maintained between instrumental set and implant, saving surgical time and reducing the use of images intensifier. ?These innovations result in the surgical procedure success, diminishing considerably locking time for patient's benefit since ischemia short time reduces deep veined thrombosis risk, of infection by the minimum approaches that are carried out, patient s fast recovery to incorporate in short time to rehabilitation and his work and life routine. ?Having more advantage since in necessary case of dynamiting the system, it counts with a proximal orifice so that upon withdrawing one of the proximal screws the other one works as dynamic locking, this in cases of consolidation or pseudoarthrosis delay.
