Abstract

Introduction: Hip fractures are one of the most common fractures in adults encountered in orthopedics, posing a great deal of risk to patients’ life. Hip fractures include subtrochanteric, intertrochanteric, and femoral neck fractures. The proximal femur’s geometry has drawn more attention recently in relation to the etiology of hip fractures. Higher femoral neck-shaft angles (FNSAs) have been implicated in a predisposition to hip fractures.
Materials and Methods: A cross-sectional comparative study conducted at a tertiary care center in western part of India. Two groups of 50 individuals each created, matched for age range and gender, one control and the other with unilateral hip fracture.
Results: On conducting a binary logistic regression with absence or presence of fracture being the dependent variable and FNSA being covariate, an Odd’s ratio of >1 identified, indicating the likelihood of higher FNSA values seen in fracture group than in control group. P value also found to be <0.05 hence significant. No significant difference was noted between the FNSA of males and female patients in fracture group. FNSA was higher in fracture group than in control group, mean FNSA 136.8 and 132.3°, respectively. We have noted an increased risk of hip fractures in patients with higher FNSA matched with their age and gender. This is confirmative of the findings noted in previous studies.
Conclusion: Hip fracture risk appears to be increased in those with higher FNSA. Although the precise cutoff value is yet unknown, this link could serve as the foundation for prevention in individuals whose values are high – that is, >136° – according to this study. Further, evaluation is needed for conclusive understanding of their relationship.
Keywords: Femur neck shaft angle, Hip fractures, Relative risk.
