Purpose: The paraspinal muscles, particularly the multifidus and erector spinae, are essential for supporting physiological loads, coordinating functional movements, and ensuring lumbar segment stability. This study aims to evaluate the effectiveness of Uni-Portal Bi-Channel Dual-Media Transforaminal Lumbar Interbody Fusion (UBD-TLIF) versus Minimally Invasive Transforaminal Lumbar Interbody Fusion (MIS-TLIF) in minimizing paraspinal muscle damage during lumbar surgeries.
Methods: This retrospective study analyzed patients who underwent single-level UBD-TLIF or MIS-TLIF from January 2020 to December 2022. Key outcomes measured included preoperative and postoperative Visual Analog Scale (VAS) scores for back and leg pain, Oswestry Disability Index (ODI) scores, radiological changes in paravertebral muscle integrity via MRI, operative time, estimated blood loss, and length of hospital stay.
Results: Among 103 patients (51 cases in UBD-TLIF group), no significant baseline differences were observed. Although UBD-TLIF takes longer operative time (210.80± 71.86 min vs 181.12± 36.74 min, P=0.002), UBD-TLIF group showed a significant less reduction in fat infiltration with a mean change of 7.29± 2.46 versus 10.51± 3.72 for MF (P< 0.001) and 4.63± 1.98 versus 7.62± 2.83 for ES (P< 0.001). Earlier recovery was noted in UBD-TLIF group, with Day 3 postoperative VAS scores for back pain significantly lower (2.12± 0.84) compared to MIS-TLIF (3.48± 1.08, P< 0.001), also shorter length of hospital stay (7.02± 1.75 vs 8.38± 1.33, P< 0.001). Additionally, UBD-TLIF group showed less estimated blood loss (155.69± 93.41mL vs 230.96± 102.18 mL, P< 0.001).
Conclusion: UBD-TLIF offers clinical outcomes comparable to MIS-TLIF for single-level lumbar interbody fusion surgery while providing enhanced muscle preservation and faster postoperative recovery. Additionally, the use of T2-weighted MRI and ImageJ software for measuring fat infiltration rates proves to be a reliable method.
