Abstract

OBJECTIVES
The purpose of this analysis is to study whether the factors including bone mineral density (BMD) and age which influence fracture occurrence is involved in proximal femur fracture type. Any correlation of body mass index (BMI) and obesity to fractures of the proximal femur was investigated in particular.
METHODS
Two hundred fifty two patients hospitalized for femur neck fracture and intertrochanteric fracture over 60 under 90 years old were examined. Only simple fall down trauma for excluding pathologic fractures was included. About 225 patients, past medical, drug and social history were investigated and BMD and BMI (body mass index) were measured. Patients were classified into two groups (femoral neck fracture and intertrochanteric fracture). Significant differences in BMD and BMI between these two groups were investigated.
RESULTS
There was no statistically significant difference between two proximal femur fracture type with regard to age, sex and BMD. But two groups seem to have statistically significant different with BMI. Most patients had normal weight, thus no significant differences were found in degree of obesity between two groups.
CONCLUSIONS
This study shows that the higher the patients have BMI, the more frequently intertrochanteric fracture is occurred. But, owing to normal obesity levels seen in most patients in this study, any definitive correlation between obesity and each type of proximal femur fracture could not be found.
