ESR erythrocyte sedimentation rate, CRP C-reaction protein, pre-op pre-operation, post-op post-operation, PA _– B, PA _– C, and PB _– C P value of comparison between group A and B, A and C, B and C, respectively
^※Student–Newman–Keuls test, compared post-operation kyphosis angle with pre-operative in the three groups, Pa = 0.0003, Pb = 0.0001, Pc = 0.0001; *Student–Newman–Keuls test, compared the final follow-up kyphosis angle with post-operation in the three groups, Pa = 0.0523, Pb = 0.2410, Pc = 0.1321; ^#,¥Student–Newman–Keuls test, compared ESR, CRP in 3 month post-operation with pre-operative in the three groups, P < 0.05
