In this study, we compare intermediate-term outcomes in minimally invasive surgical transforaminal lumbar interbody fusion (MIS TLIF) to open TLIF. Sixty-four patients who underwent 1- to 2-level MIS TLIF with baseline, 1-, and 2-year outcome measures were identified. These were propensity-matched to a cohort of open TLIF patients based on age, body mass index, sex, smoking status, workers' compensation status, and preoperative outcome measures. At 1 year, both groups had similar improvements in pain and Short-Form 36 (SF-36) Physical Composite Summary (PCS), but the MIS TLIF group had a statistically significantly greater improvement in Oswestry Disability Index (ODI) compared with the open TLIF group. At 2 years, the MIS TLIF group had a statistically significantly greater improvement in pain and ODI compared with the open TLIF group, but no statistically significant difference in SF-36 PCS. Both MIS TLIF and open TLIF lead to significant improvements in clinical outcomes. At 1 year after surgery, MIS TLIF patients had greater improvements in ODI, and at 2 years after surgery, they had greater improvements in pain and ODI. This study showed that the perioperative advantages of MIS TLIF, such as less muscle dissection and faster recovery, continue to be beneficial 1 to 2 years after surgery.
