a “Line a” is the projection line of the centers of the talar dome. b After the central sagittal plane (CSP) is determined, on this plane the tIN and three AP locking screws (S13, S15 and S37) are simulated. The relationship between AP locking screws and the PMF is demonstrated. c Measurements on reconstructed 3D model: the fragment height (FH) and the minimal distance from distal AP locking screw tip to the PMF (DSF). d Measurements on axial scan: minimal distance from the nail tip to the PMF (DNF)
