The epidemiology of fractured femurs and the effect of these factors on outcome

Abstract

We have analysed 250 cases of fractured shaft of the femur with the objective of highlighting any preventative measures and anticipating morbidity associated with cause and type of injury. The younger patients typically injure themselves as pedestrians, motorcyclists and bicyclists in Summer. The older patients tend to have falls in late Summer and Winter. The outcome varies depending on the cause, type and age of the injured person. The greatest morbidity was found in high-velocity accidents involving motorcyclists, pedestrians and car accidents. Knee flexion is a particular problem with these injuries and we are currently using continuous passive motion in conjunction with a continuous opiate infusion where this is likely to be a problem. The results also suggest that the mechanism of injury and its possible prevention, particularly in motorcycle design, could be as important as the type of treatment. Elderly females following falls also form a distinct group, suggesting that osteoporosis is a major factor with the best outcome associated with treatment by internal fixation. We feel that age alone should not be a reason for exclusion from intramedullary fixation and this merits further study.
