Elastic intramedullary osteosynthesis for the treatment of metaphysodiaphyseal non-union of the femur and tibia.

Elastic osteosynthesis is capable of producing the biomechanical conditions required to reconvert mature fibro-cartilaginous tissue interposed in the non-union in bone tissue. Theory is confirmed by a retrospective study of 54 patients affected with nonunion of the femur and tibia treated with elastic osteosynthesis.
