Note: Bold indicates statistically significant values. Multiple comparisons of CK at different time points using the Bonferroni post hoc test, and at least one identical subscript letter denoted no significant difference from each other at the 0.05 level.

Abbreviations: Wiltse, Wiltse approach transforaminal lumbar interbody fusion; MIS‐TLIF, minimally invasive transforaminal lumbar interbody fusion; PLIF, posterior lumbar interbody fusion.
