Different risk magnitudes of femoral neck and intertrochanteric fractures in Thai women.
OBJECTIVE
To study the risk factors associated of femoral neck and intertrochanteric fractures in Thai women.


METHODS
A case,control study was conducted in Bangkok and its vicinity between 1997 and 1998 to compare factors related to each type of hip fracture in Thai women. Cases, aged > or =51 years old, were diagnosed as intertrochanteric or femoral neck fracture and were matched with controls by age and sex. Multinomial logistic regression was performed for significant associated factors.


RESULTS
Recent physical activity and steroid-containing traditional medicine were strongly associated with intertrochanteric fractures (adjusted odds ratio (OR) 0.17 (95% CI: 0.07, 0.42) and 6.50 (95% CI: 1.93, 21.82), respectively) when compared to femoral neck fractures. Cerebrovascular accident (CVA) was more related to femoral neck fractures when compared to intertrochanteric fractures (adjusted OR 8.63 (95% CI: 2.28, 32.66), and 4.79 (95% CI: 1.19, 19.29), respectively).


CONCLUSIONS
Intertrochanteric fracture could be minimized more by encouraging physical activities and avoidance of steroid use while the reduction of femoral neck fracture should be achieved more by CVA prevention.
