Cha YH, et al. - This study attempted to examine differences in geometrical properties of the proximal femur and predict the occurrence of basicervical fractures through a comparative study of the femoral neck and basicervical fractures in patients undergoing hip structural analysis (HSA). Between March 2017 and December 2019, all individuals with hip fractures who were at least 65 years old and admitted to our hospital were eligible for this study. Researchers recruited a total of 149 femur neck fractures and basicervical fractures (intertrochanteric fractures of A31.2) during the study period. The final analysis enrolled 59 patients. Using HSA, proximal femoral geometric analysis is a beneficial method for predicting the type of hip fracture. The results demonstrate that a lower cross-sectional moment of inertia, a shorter hip axis length, and lower grip strength are major predictors of basicervical fractures.
