We analysed the daily number of emergency call-outs in an orthopaedic clinic for the period 1995-1999 and the corresponding index Ap of daily global geomagnetic activity. We found that both kinds of the annual time series represent fractal dynamics as revealed by the Fast Fourier Transform of the series. The time series showed a seasonal wave like pattern. The minimum and maximum values of these waves revealed, to a first approximation, a negative correlation between Ap an emergency call-outs. A change in the average geomagnetic activity from one season to another can be accompanied by an up to about 16% effect on the average number of emergency call-outs. This proved that the human organism, continuously cumulates small or unnoticeable effects of the geomagnetic activity and the effect is only seen when examined over long periods of time of the order of seasons.
