title: Factors related to occurrence of hip fracture during a fall on the hip.
abstract: Recently, it has been shown that hip fractures can be effectively prevented by use of hip protectors. To determine who would gain most benefit from use of hip protectors, we conducted a study with the aim to clarify factors that contribute to the occurrence of fracture in individuals who fall on their hip. Hip fracture patients were compared with individuals who had fallen on their hip without sustaining a fracture. The study group consisted of 123 consecutive hip fracture patients aged 70 years or over (mean age 82 years, female 82 years and male 80 years). The control group comprised 132 individuals (mean age 81 years, female 81 years and male 80 years) obtained from a prospective study on falls, who had experienced a fall that caused a visible soft tissue injury (bruise or wound) at the hip or gluteal region without sustaining a fracture. Patients were questioned about associated diseases, medications, place of residence, walking ability, need for locomotor aids and some activities in daily living (ADL). Patients who sustained a hip fracture were more likely to be women, living in long-term institutional care, using neuroleptics, dependent in ADL and had more history of previous stroke with hemiparesis, more Parkinsonism and lower body mass indexes (BMI) than those who did not sustain a fracture on fall on the hip. According to a logistical regression model, institutional residence, low BMI and history of stroke with hemiplegic status differed between fracture cases and controls. Institutional residence, low BMI and history of hemiplegic stroke discriminate hip fracture patients from fallers who sustain a soft tissue injury on the hip region. In clinical practice, patients who have these characteristics would be potential candidates to use hip protectors and other preventive measures.
