[Primary disability in patients with tuberculous spondylitis and the ways for its decrease].

Causes responsible for invalidity were analysed in 167 patients with a circumscribed form of tuberculous spondylitis. The causes were divided into 4 groups: diagnostic errors; errors in treatment; prognostic errors (late indications to surgical treatment); organizational errors. Heightening of the quality of early diagnosis of tuberculous spondylitis at a primary application to a medical institution and timely high-quality specific therapy in the antituberculous institutions will contribute to an increase in treatment effectiveness and invalidity reduction.

[The surgical treatment of disseminated forms of tubercular spondylitis using Byzov's apparatus].

Analysis of treatment of 123 patients with disseminated forms of tuberculous spondylitis is presented. Among the patients 67 (54.4%) subjects were over 55 years of age. The main cause of disseminated spondylitis forms was ungroundlessly prolonged conservative treatment under bed regime. As a result, symptoms of low cardiac activity were seen in 79 (64.2%), lymphovenous stasis in 22 (17.8%) and osteoporotic signs in 38 (30.8%) patients. Complications and concurrent diseases in 41 (33.3%) of the cases prompted surgery from the posterior approach, in 82 (66.7%)--from the anterior approach with replacement of the defect by an autograft or biocompatible implant with extrafocal posterior fixation of the operated segments by Byzov's apparatus. The patients became active beginning on days 7-12 of postoperation, which promoted reparative process normalization in the operative area. The late therapeutic results were studied in 117 patients. Support capacity recovered in 99 patients and improved in 18. The method used is functionally justified, well tolerated by patients and highly effective in treating the abnormality.

[Extra-focal instrumental fixation of the spine in the surgical treatment of tuberculous spondylitis].

The complex procedure for treating tuberculous spondylitis involving a short-term (1-2 months) antibacterial therapy and early functional resection of the diseased vertebral bodies with defect replacement by an autograft and extra-focal fixation of the resected spinal portion by Byzov's apparatus applied in 492 patients proved to be highly efficacious. The reliable apparatus fixation of the spinal zone operated on allows early (on day 7) activation of patients which promotes functional normalization of organs and systems, activation of reparative processes, shortening of treatment duration and reduction of disabled cases. Clinical and X-ray findings show that a bone block formed 4-6 months after surgery and 67% of the patients finished their therapy during a year. Introduction of the procedure into the treatment of spinal injuries and diseases will be of the socioeconomical value.

[Surgical treatment of hematogenic spinal osteomyelitis using extra-focal instrumental fixation].

A total of 78 cases with acute hematogenic vertebral osteomyelitis are analyzed. Diagnostic errors at the prehospital and hospital stages are specified in 42 cases (53.8 percent), that resulted in late start of adequate treatment. Preoperative antibacterial therapy was carried out 1 to 1.5 months before surgery consisting in radical resection of the focus with replacement of the defect with autotransplant and extra-focal++ fixation with Byzov's apparatus. After surgery the patients started exercises on days 5-10. This treatment resulted in formation of osseous block at the site of vertebral body resection in 3-4 months in 30.8 percent of cases, in 5-6 months in 57.7 percent, and in 10-12 months in 11.5 percent of patients.

[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.
