The incidence of subsequent contralateral hip fracture and factors associated with increased risk: the IMPACT Contralateral Fracture Study
Authors' conclusion
One in 40 (2.5%) hip fracture patients sustained a contralateral fracture within 12 months of their index fracture, and deprivation was associated with a reduced risk of contralateral fracture.
