The device NAJA is an implant dedicated to the correction and stabilization of the spine during fusion of the instrumented levels. It consists of:
. A braid allowing correction and stabilization of the levels, after tensioning
. A connector designed to be fixed on a rod and holding the tension on the braid
Because of its conception, and in order to obtain symmetric constructions, two versions are available for each size of the implant: one for the left size, one for the right side.
