An analysis of lifetime fractures in women with epilepsy.
OBJECTIVE
To clarify the relationship between fractures and antiepileptic drug (AED) use.


METHODS
Menopausal women with epilepsy were interviewed at two clinics regarding site, year and circumstances of any fracture, duration of AED use and menopause. Fracture sites were analyzed according to AED use.


RESULTS
Twenty-nine fractures occurred in 20 of the 50 interviewed subjects (mean age 54). Nine occurred prior to AEDs; seven attributed to accident and two to clumsiness. Twenty occurred on AEDs; 10 attributed to clumsiness (most in the leg and foot), eight to seizure (most in the arm or hand) and two to accident. Duration of AED exposure was similar in both groups and in osteoporotic vs non-osteoporotic sites.


CONCLUSIONS
Epilepsy therapy may contribute more to the lifetime occurrence of fracture than seizures themselves. More screening for osteoporosis is required. While adjusting doses to prevent seizures, ongoing screening for neurotoxicity must be maintained in order to avoid fractures.
