[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.
