Risk factors for cervical and trochanteric hip fracture during a fall on the hip.
OBJECTIVE
The aim of this study was to elucidate factors related to hip fracture in patients who fall on the hip in order to identify those patients who might benefit from the use of hip protectors.


METHODS
The study was performed by comparing 146 persons who had fallen and sustained a soft tissue injury in the hip region with 146 cervical hip fracture and 146 trochanteric hip fracture patients matched for age, sex and place of residence.


METHODS
The fall group was drawn from a prospectively collected cohort of 1,061 elderly people participating in an epidemiological survey on fall injuries; the fracture group was drawn from a prospectively recorded hip fracture database of the Oulu University Hospital (n = 1,714).


METHODS
Demographic data, place and mechanism of falling, walking ability, associated diseases, medication.


RESULTS
In a stepwise polychotomous conditional logistic regression analysis, the following significant and independent risk factors for both fracture types were seen: low weight, tall height, falling from standing height and respiratory disease. Falling indoors was a risk for only trochanteric fractures, while inability to walk alone outdoors was a risk for only cervical hip fractures.


CONCLUSIONS
Elderly persons with low weight, tall height, respiratory disease, tendency to fall indoors and inability to walk alone outdoors should be candidates for the use of hip protectors.
