[The effect of stable fixation of the fragments on the course of experimental traumatic osteomyelitis].

The authors have carried out two series of experiments on 15 dogs making a comparative x-ray morphologic study of the course of traumatic osteomyelitis in the conditions of immobilization of the fragments with a plaster bandage and a perosseous osteosynthesis apparatus. It has been demonstrated that the mobility at the junction of the fragments area causing secondary local disturbances in microcirculation is a factor determining steady progress of the suppurative inflammatory process and its transition into the chronic stage of the disease. Meanwhile early creation of high stability of the fragment fixation with a perosseous osteosynthesis apparatus ("neutral osteosynthesis") preventing secondary traumatization of the fragment ends creates optimal conditions for self-healing, i. e. for the inflammatory process fading and for the completion of the fragment consolidation.
