ABSTRACT
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 head-neck angle and y-axis displacement distance (all rs > 0.89, p < 0.01).
CONCLUSIONS: MIMICS-based FNF parameter measurement accurately describes spatial characteristics post-fracture, providing guidance for FNF treatment and evaluation.
