Diagnostics of instability at patients with degenerative disease of lumbar and sacral spine
Objective. To analyze the literature data dedicated to diagnostics of vertebral segment instability at patients with lumbar osteochondrosis. Material and methods. Search for Russian literature data was performed in central scientific library of First Medical State University n.a. I.M. Sechenov with the usage of internal search system. Search for English literature data was conducted via Internet using Pubmed and Medscape. The following key words were used during search: vertebral osteochondrosis, degenerative disease, lumbar and sacral spine, instability. Only full-text articles were analyzed. Results. We found and analyzed 50 literature sources according to our criteria. The biomechanical base for vertebral instability development are enlighted as well as hypotheses of such condition development are discussed. The detailed results of modern trials dedicated to estimation of clinical and instrumental examination of instability are presented. Conclusion. The problem of lumbar instability because of vertebral osteochondrosis is widely studied. Mostly the term «instability» is justified as clinical term. Nowadays there are no instrumental method of examinations correlated in 100% with clinical manifestation of instability
