Comparison of functional and radiographic outcomes between two-level oblique lumbar interbody fusion and minimally invasive transforaminal lumbar interbody fusion in degenerative lumbar disease: a retrospective study in Thailand

Key Points

• This study aims to compare the effectiveness of OLIF and MIS-TLIF in improving outcomes for patients with two-level degenerative lumbar disease.
• Conducted a retrospective analysis of patient records.
• Evaluated functional outcomes including pain and disability.
• Assessed radiographic parameters to measure correction.
• Compared short-term effects of OLIF versus MIS-TLIF.
• Both OLIF and MIS-TLIF significantly reduced pain and disability.
• MIS-TLIF provided faster short-term relief of leg pain.
• OLIF achieved better radiographic correction than MIS-TLIF.
• Further large-scale studies are needed to confirm these findings.
