[External instrumental fixation of the spine in the treatment of spinal diseases and injuries].

The authors analyze the results of treatment of 358 patients with specific and nonspecific spondylitis and with aftereffects of unstable fractures of the vertebrae proper, who have been operated on the spine destruction or instability area with the extrafocal fixation of the operated on segments by means of the Byzov apparatus. This method has yielded good clinical and functional results, effected the stability of the anterior and posterior portions of the operated on sites; it permits early (starting from the 5th-10th day postoperation) exercise of the patients, helps normal functioning of the body organs and systems, and activates the repair processes in the operated on sites. The incidence rate of the postoperative complications drops drastically, the patients rapidly recover their working abilities, and the invalidism is more rare.
