[Neurologic complications of osteoporotic vertebral compression. 3 new cases and critical analysis of the literature].
Three new cases of neurological complication by osteoporotic compression are reported. They are: a medullar compression by compression of D12 in a 66 year old woman, a deficient cruralgia by compression of L1 in a 67 year old man, and another deficient cruralgia due to the compression of L3 and L4 in a 55 year old woman. The literature presents 16 cases of neurological compressions by vertebral compressions attributed to the osteoporosis: two in 1958, and the others as from 1987. The only recently recognized feature of these complications can be explained by the axiom according to which "there are no neurological complications in the course of osteoporotic compressions" and by the introduction of new diagnosis techniques. However, the critical analysis of the published cases enables us to retain only 11 indisputable cases which, with our three observations, allows us to define certain features: the osteoporosis does not have any particularity compared to the uncomplicated form; the dorsolumbar junction is preferentially affected; the neurological complication occurs progressively and belatedly; the usual mechanism is the recoil of one of posterior vertebral corners, different from the globally convex bulging of tumoral compressions: it could be an element of the differential diagnosis. The surgical treatment gives better results.
