[Surgical treatment of fractures of the long bones in children. Interference between osteosynthesis and the physiological processes of consolidation. Therapeutic indications].

Flexible medullary nailing is an excellent method when operative treatment of fractures in children is indicated. It is a new biomechanical concept using prebent flexible rods introduced in the medullary canal through a metaphyseal area. This method can be used in all types of Femoral, Tibial, Humeral or fore arm fractures. In Each case, the operative technique is described. This closed surgical procedure has a low complication rate (no sepsis, no delayed union, no length discrepancy). Early mobilization is often possible and cast is not necessary.
