Different risk magnitudes of femoral neck and intertrochanteric fractures in Thai women.

Abstract

OBJECTIVE: To study the risk factors associated of femoral neck and intertrochanteric fractures in Thai women. MATERIAL AND METHOD: 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). CONCLUSION: 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.
