The purpose of this study was to develop guidelines to improve the health of an elderly population classified into unilateral and bilateral hip fracture groups based on the mortality and risk factors affecting survival time. In the bilateral fracture group, the incidence of fracture was 3.1%, whereas mortality was 35%, average age was 83.9, and the male to female ratio was 3:17. In patients older than 75 years of age with a unilateral fracture, close ambulatory follow up is needed to avoid bilateral fracture and protect against secondary fracture within 3 years.
