Functional outcome and mortality in geriatric distal femoral fractures

Abstract: Background: Fragility fractures are a major health care problem worldwide. Due to the ageing population an increase of distal femoral fractures is to be expected. We studied the long-term functional outcome and their influencing factors in geriatric patients with LISS-plated distal femoral fractures. Patients and methods: A cohort study with functional long-term follow up examination was carried out in a level one trauma centre on distal femoral fracture patients 65 years and older. Of 53 consecutive patients who were treated in our hospital, 43 patients with a mean age of 80 years met our inclusion criteria. 48.8% died within the study period of 5.3 years. On the remaining patients the residential status, the Barthel index and the Parker score were assessed. Results: The mean Barthel index was 47.7 and the mean Parker score was 3.5. 23% were found to be totally housebound and 26% were not able to perform any social activity. Only 18% were able to walk unaided. Patients with any medical complication had significantly higher mortality rates. Patients with extraarticular fractures had better mobility scores. Nursing home residents showed higher mortality rates but compared to patients coming from their own home the difference regarding Barthel and Parker scores remained non-significant. Conclusion: This study documents the poor functional long-term outcome of geriatric patients with distal femoral fractures. In comparison to other fragility fracture patients it seems that this population is at higher risk to die in-hospital during their perioperative course. Medical complications have to be avoided as they were found to be associated with worse functional outcome and higher mortality rates. An osteoporosis therapy may be associated with reduced mortality rates also in these patients. [Copyright &y& Elsevier]
