Is there any Relationship between Proximal Femur Fracture Site and Hip Anatomy?

INTRODUCTION: There are few studies reporting the relationship between hip fracture site and hip geometry and bone mineral density in the literature. The forces affecting the hip joint, the arm of the force and the angle of the load are the basis of hip biomechanical studies. The angle of the proximal femur and the morphological parameters are important for stress distribution due to the response to the burden. We think that the morphological differences of the proximal femur are related to the fracture type.
METHODS: Between 2015-2018, patients who applied to the hospital with femur fracture were listed. One thousand twenty-four femur fractures were detected. Pertrochanteric, femoral neck and subtrochanteric fractures were selected on the list. Patients with appropriate pelvis X-rays were identified. Intertrochanteric distance, femoral neck length, femoral neck width, lateral offset length, neck- shaft angle and acetabulum center-edge angle were measured by one orthopedic surgeon.

RESULTS: Significant statistical results were found between collum femoris fractures and collodiafizer angles of subtrochanteric fractures (p=0.0117). Significant statistical results were also observed between pertrochanteric fractures and subtrochanteric fractures (p=0.0439). Comparing with the subtrochanteric group and the femoral neck group’ CE angles, a significant difference was found (p=0.0490). There was no statistically significant difference between pertrocanteric group and subtrochanteric group (p=0.2614).
DISCUSSION AND CONCLUSION: To our knowledge, this is the first morphological femur fracture study that was conducted for Turkish society in the literature. An advantage of our work is that this study can be used to design an implant.
