ABSTRACT
OBJECTIVES: A significant number of patients who had a previous surgical treatment in the hip area experience subsequent hip fracture (SHF) on the opposite side. This study aims to analyze the risk factors and the correlation between osteoporosis and SHF on the opposite side by measuring bone mineral density (BMD) and treatment provided by risedronate for the prevention of SHF. MATERIAL & METHODS: We studied 475 patients without treatment who had unilateral hip and included following: death, SHF, alcoholism, living alone, dementia, dizziness, health status, osteoporotic treatment after fracture and BMD from March 1997 to June 2006. We selected 26 patients with SHF and the other 26 patients without SHF who had similar age, sex, BMI, BMD, diagnosis, treatment and follow up. The average follow up was 6.4 years (4~12 years) and 6.2 years (4~12 years).
