[Theoretical grounds for free osteoplasty in suppurative infection].

From the materials of extensive experimental studies and clinical observations the theoretical grounds for the free bone plasty under the conditions of purulent infection were devised. The methods of investigation of the microcirculatory vascular bed, luminescent microscopy with a tetracycline mark, photometry, planimetry and other specific tests were applied. Findings obtained in earlier experiments on 2000 animals (rabbits and dogs) and data of supplementary special studies on 185 rabbits were used. It was found, that from the point of view of the condition of the microcirculatory bed and osteogenetic potentiatlities of the mother bone, the free bone plasty is quite grounded theoretically. The authors' theoretical postulates are supported by successful treatment of 47 patients with hematogenic spine osteomyelities, subjected to bone plasty of the defects formed after the removal of purulent inflammatory foci.
