Functional Ability After Hip Fracture Among Patients Home-dwelling at the Time of Fracture

The aim of the study was to assess the change in function and residential status four months after hip fracture in patients over 50 years of age and living independently at home at the time of fracture. All consecutive hip fracture patients treated at Oulu University Hospital during 1989--1999 were followed up. Data collection was done on standardized hip fracture forms, which were filled in at admission and at four months postoperatively. The forms included demographic data, place of residence, locomotor ability, use of walking aids, data on the fracture and its treatment, hospital stay, place of discharge and pain. At four months, 16.0% of the men and 14.3% of the women were permanently institutionalized. Preoperatively, 81.1% of the patients had been able to walk out of doors either alone or accompanied, while at 4 months, less than half of the patients (149 men, 391 women) were able to do so. Two thirds of the hip fracture patients had been able to walk without walking aids before the fracture, the corresponding proportion being one fifth at four months after the fracture. Cumulative mortality at 4 months was 9.9%, being higher among the male (15.5%, n=53) than the female patients (7.9%, n=75). The original study population was also divided into two subgroups operated at different period of time (1989--92 and 1993--99), the functional results seemed to improve with time. Hip fracture leads to the institutionalization of every seventh patient able to live at home at the time of fracture and impairs markedly one's functional capacity. To restore the pre-fracture status as well as possible and to reduce the burden of the consequences of hip fracture, it might be beneficial to evaluate and improve the existing rehabilitation system.
