[Delayed paraparesis after osteoporotic vertebral fracture--with special reference between mechanism of symptoms, fracture level, age and operative methods].
We examined the operated 53 cases with delayed paraparesis after osteoporotic vertebral fracture. The causes of the symptoms were complicated and the analysis indicated that the anterior approach should be the first choice, however the posterior approach could be indicated for the following cases ; the main causes are posterior elements, multiple involvement, at middle and lower lumbar level, with severe osteoporosis, with systemic complication, over 80 years old. For high aged and osteoporotic patients, careful analysis of factors causing symptoms and less invasive operation as possible are needed.
