[Neurologic complications of osteoporotic spinal collapses. Apropos of 8 cases].
The prevalence of neurological complications in patients with osteoporotic vertebral collapse and the risk factors for neurological compromise were studied retrospectively in 138 inpatients. Six per cent of patients had objective neurological loss. Patients with neurological loss were more likely to have changes suggestive of malignant disease on roentgenograms, computed tomography, and magnetic resonance imaging. Diagnosis was based on magnetic resonance imaging and examination of vertebral biopsy specimens. Comparison of patients with and without neurological loss suggested that an intravertebral vacuum phenomenon and/or a cortical osteoporosis may cause fracture of the posterior wall and therefore compression of neurological structures.
