Risk of fractures in patients with multiple sclerosis: record-linkage study.

BackgroundPatients with multiple sclerosis (MS) have been reported to be at higher risk of fracture than other people. We sought to test this hypothesis in a large database of hospital admissions in England.MethodsWe analysed a database of linked statistical records of hospital admissions and death certificates for the whole of England (1999-2010). Rate ratios for fractures were determined, comparing fracture rates in a cohort of all people in England admitted with MS and rates in a comparison cohort.ResultsSignificantly elevated risk for all fractures was found in patients with MS (rate ratio (RR) = 1.99, 95% confidence interval (CI) = 1.93-2.05)). Risks were particularly high for femoral fractures (femoral neck fracture RR = 2.79 (2.65-2.93); femoral shaft fracture RR 6.69 (6.12-7.29)), and fractures of the tibia or ankle RR = 2.81 (2.66-2.96).ConclusionsPatients with MS have an increased risk of fractures. Caregivers should aim to optimize bone health in MS patients.
