Analysis of magnetic resonance image (MRI) quality after open (Op)‐transforaminal interbody fusion (TLIF) and minimally invasive (MI)‐TLIF with the implantation of structurally different systems has not previously been performed. The objective of this study was to conduct a comparative analysis of the postoperative MRI following MI and Op one‐segment TLIF. Material and Methods: The nonrandomized retrospective single‐center study included 80 patients (46 men and 24 women) aged 48 + 14.2 years. In group I (n = 20) Op‐TLIF with open transpedicular screw fixation (TSF) was performed, in II group (n = 60), the MI‐TLIF technique was used: IIa (n = 20)— rigid interspinous stabilizer; IIb (n = 20)—unilateral TSF and contralateral facet fixation; IIc (n = 20)— bilateral TSF. Results: Comparison of the quality of postoperative imaging in IIa and IIb subgroups showed fewer MRI artifacts and a significantly greater MR deterioration after Op and MI TSF. Comparison of the multifidus muscle area showed less atrophy after MI‐TLIF and significantly greater atrophy after Op‐TLIF. Conclusion: MI‐TLIF and Op‐TLIF with TSF have comparable postoperative MR artifacts at the operative level, with a greater degree of muscle atrophy using the Op‐TLIF. Rigid interspinous implant and unilateral TSF with contralateral facet fixation have less artifacts and changes in the multifidus muscle area.
