[Pathogenesis of osteopathy caused by anticonvulsives (author's transl)].

After a short survey of the recent suggestions of the pathogenesis of osteopathy caused by therapy with anticonvulsives it is demonstrated in the light of 3 case reports that 1. A vitamin D-sensible rickets, which is only due to abnormal living conditions, can develop in severely cerebral-damaged persons if there is no specific vitamin D administration. 2. An "antiepileptic rickets" is spontaneously reversible if the anticonvulsive therapy is stopped. 3. An enzymatic induction due to anticonvulsives is also detectable in the light of morphologic hepatic changes (biopsy, electron microscopy). Hence it follows that there are demands for a specific control of all patients treated with anticonvulsives. It is recommended to carry out a rickets prevention for a selected patient group.
