Evaluation of a Porous Bioabsorbable Interbody Mg-Zn Alloy Cage in a Goat Cervical Spine Model

Figure 2

Changes of serum biochemical parameters after treatment with the Mg-Zn alloy. (a) The serum Mg ion concentration increased within 6 weeks and then steadily decreased. The changes of the Mg ion concentration at 6 weeks and 12 weeks were statistically significant (P = 0.0062 and P = 0.0044, respectively). (b), (c), and (d) Significant changes were not observed in the levels of the serum Zn ion concentration, CREA, and BUN (all P > 0.05). The average baseline of the 4 above parameters for all 24 goats was 22.25 ± 5.77 mg/L, 3.66 ± 0.79 mg/L, 11.70 ± 2.53 mmol/L, and 104.82 ± 17.50 μmol/L, respectively.
