Application of MINICS software in measuring parameters of femoral neck fractures and its clinical significance

Objective: This study aimed to investigate the application of MIMICS software in measuring femoral neck fracture (FNF) parameters and its clinical significance.Method: Computed tomography data from 72 patients with FNFs were used to reconstruct three-dimensional (3D) models using MIMICS.The FNFs were divided into valgus and bowing groups based on the coronal femoral head-neck angle.A simulated sphere identified the center of the femoral head, and a 3D coordinate system was established.Statistical analyses were performed.Results: The valgus group showed more lateral x-axis and upward z-axis displacement (both p < 0.01).The medial x-axis and downward z-axis displacement distances were larger in the bowing group (both p < 0.01).Strong positive correlations were found between the horizontal head tilt angle and head spacing, spatial headneck angle and y-axis displacement distance (all r s > 0.89, p < 0.01).Conclusions: MIMICS-based FNF parameter measurement accurately describes spatial characteristics post-fracture, providing guidance for FNF treatment and evaluation.
