A STUDY OF COMPLAINTS AND THEIR RELATION TO VERTEBRAL DESTRUCTION IN PATIENTS WITH OSTEOPOROSIS

Patients with spinal osteoporosis suffer from vertebral deformation, loss of height and back pain, as well as from functional limitations and alterations of mood. So far little is known about the extent of these clinical symptoms at all and whether they are related in a predictable manner to the fractures or damages of bone structure. In the present study we investigated the relation between vertebral deformation and clinical symptoms in 70 patients with osteoporosis. Clinical data like pain, functional limitations and parameters of mood were examined by a standardized questionnaire. The numbers of vertebral fractures were determined, and the vertebral destruction was quantified using the Spine Deformity Index (SDI). The symptoms and functional limitations were graded and correlated to the SDI and the number of fractures. Our results underline a relation between the extent of vertebral deformation and the reduction in quality of life by pain, functional limitations and alterations of mood. This relationship was absent or less evident, if the number of fractures was taken into account. Besides the difficulties concerning the grading and quantification of clinical symptoms and outcome of disease, our study revealed that there is a causal relation between the extent of vertebral destruction measured by the SDI and the extent of these clinical parameters. © 1990.
