[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.
