The paper present our results in application of new method for nonunion treatment of the femoral diaphysis.

The internal fixator has been applied with 36 patients. Bone graft substitution is used with 11 (30,5%) patients. The method of placement and results of the work according to the modified system of the Karlstrom-Olerud method have been presented. Excellent condition was found with 25 (69,4%) patients, satisfactory with 8 (22,2%) and poor with 3 (8,3%) patients. Average healing time is 57 weeks.

The method in which the internal fixator is applied provides complete stability of the nonunion and makes possible spontaneous-biological dinamization of the nonunion. It doesn’t damage the periosteal and medullary bone vascularization which favors healing process.
