title: Seasonal variation in the incidence of hip fractures in Emilia-Romagna and Parma.
abstract: Though some reports suggest the existence of seasonal changes in hip fracture incidence, with a peak in winter months, other investigations have failed to confirm this finding. In this study we present data on the month-to-month variability of hip fractures in Emilia-Romagna, a region of Northern Italy with a population of approximately four million inhabitants, and in Parma, a province of Emilia-Romagna (population of approximately 400,000). Data on cervical and trochanteric fractures were obtained from two sources: a) records of all operative procedures in the five orthopaedic centres serving the area of the Parma province; and b) a computerised database of all hospital discharges from public and private hospitals of Emilia-Romagna. In both cases, the analysis gave similar results, with no evidence of a consistent seasonal pattern in hip fracture rates.
