A comparative study of risk factors of femoral neck and intertrochanteric fracture in Thai men.

ABSTRACT

OBJECTIVE: The objective of this study was to compare the risk factors related to hip fracture between intertrochanteric 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.
