Abstract
Background
We reproduced a frequently cited study performed at our University Hospital that was published in the British Medical Journal in 1981 assessing the extent of “snow and ice” fractures during the winter period.
Methods
As per the original study, four days of snow and ice were identified as well as two control periods when snow and ice wasn't recorded; four days within the same year, with a similar amount of sunshine hours, and four days one calendar year later. The distribution of fractures according to age and sex in addition to the anatomical location were examined in relation to the presence of snow and ice as well as comparisons with the index study 33 years ago.
Results
A total of 293 patients with fractures were identified. Whilst the relative risk was not of the magnitude 33 years ago, we found a significant overall increase in fractures on snow and ice days in the age groups over 30 years old compared with both control periods. In addition, and consistent with the study 33 years ago, there was more than twice the number of forearm and wrist fractures than during the control periods.
Conclusion
A significant increase and similar distribution of fractures in relation to the presence of snow and ice continue to be identified. This appears to be despite preventative recommendations made 33 years ago.
