Risk factors for femoral neck fracture in elderly population.

Objectives: To explore the risk factors for femoral neck fracture in elderly population.

Methods: A total of 124 elderly patients (≥60 years old) in hospital for trauma were enrolled, including 71 patients (57%) with femoral neck fracture and 53 non-femoral neck fracture patients (43%). All patients' age, gender, body mass index (BMI), bone mineral density (BMD), thigh length and average circumference were collected. Single factor analysis and multivariate logistic regression analysis were performed to explore whether the above factors were risk factors for femoral neck fracture.

Results: Single factor analysis showed that the age, gender, BMI, BMD, thigh length, and average thigh circumference between the 2 groups were statistically different (all <0.05), and multi-factor logistic regression analysis showed that age, gender, BMI, BMD, thigh length, and average thigh circumference were influencing factors for femoral neck fracture in elderly population (all <0.05).

Conclusions: Older age, female, lower BMI index (low body weight), lower BMD (osteoporosis), longer thigh length, and lower average circumference are risk factors for femoral neck fracture in the elderly population.
