Prediction of a new fracture after a wrist fracture – a five year follow up
Abstract Background Falls and ensuing fractures are major challenges in our ageing population. The aim of this study was to study if clinical balance measures, function of the inner ear, self-rated health or fracture risk assessed by FRAX ® could predict future admission to hospital because of a fracture among a group of older persons with previous wrist fracture. Methods This was a longitudinal study with a 5-year follow-up. Searches in the local health authority’s patient administrative system (PAS) were performed 5 years after inclusion and baseline measurements were taken. Information was extracted about whether participants had been treated for a fracture or hospitalized other reasons during the 5-year period. Persons, 50 years and above, with previous wrist fracture (n=83). Five different clinical balance measures was assessed, postural sway was assessed by means of a force plate, vestibular asymmetry was assessed with the head- shake test, self-rated health by EuroQol 5 Dimension visual analogue scale and risk of future fracture by the Fracture Risk Assessment Tool (FRAX ® ). Age and body mass index was also used in the risk analysis. Results Age was associated with risk of future fracture, OR 1,06 (95% CI 1,01-1,12). The ability to stand on one leg with eyes open correlated significantly with future fracture (p=0.011) and so did FRAXosteo, however on the limits of significance (p=0.052). Conclusion This follow-up study showed that the one-leg standing time-test was a stronger predictor for future facture within five-years after a wrist fracture than FRAX not including a measure of balance.
