Objective : The objective of this study was to compare the risk factors related to hip fracture between inter-
trochanteric fracture and femoral neck fracture in Thai men.
Material and Method: The study was conducted in Bangkok and its vicinity from July 1997 to September
1998. The cases were recruited and matched with the controls by age and sex. Multilogit model was performed
for finding the significant factors associated to each type of hip fracture.
Results : There were 73 femoral neck fractures, 144 intertrochanteric fractures, and 177 controls. It was found
that both types of hip fracture were associated with the physical activity and the cerebrovascular accident.
However, the Chinese parent race was significantly related to the femoral neck only (adjusted odds ratio (OR)
2.59, 95% confidence interval (CI): 1.21, 5.54) whereas the walking disability was specifically associated
with the intertrochanteric fracture (adjusted OR 3.23, 95% CI: 1.29, 8.08).
Conclusion : Types of hip fracture should be concerned for strategic prevention in men since they have
significant difference of risk factors.
