Table 1.

Mean thickness (standard deviation) of superior endplates. Values are given in millimeters for C4, C5, C6, and C7 specimens, respectively. Measurements were performed at five different locations of the endplate (named −40, −20, 0, 20, 40) of the scans (named 6.00–12.00, 7.30–1.30, 9.00–3.00, 10.30–4.30)
