Morphometry evaluations of cervical osseous endplates based on three dimensional reconstructions

Fig. 1 Definition of the cervical vertebrae endplate co-ordinate system and the schematic of the measurement protocol.

Fig. 2 The lengths and trends of the curves on the inferior (A) and superior (B) endplates.

Fig. 3 The distribution of the location of the most-concave point in the axial reference plane. A and B show the distribution on the upper and lower endplates, respectively.

Fig. 4 The endplate (C5 inferior) was reconstructed in the MATALB software, according to its parametric equation. Those scattered points represented the selected landmarks on the original 3D reconstruction image.
