Comparative study of modified midline lumbar interbody fusion and modified transforaminal lumbar interbody fusion for the treatment of single-level lumbar degenerative diseases

M-MIDLIF can achieve decompression, fixation, and fusion via a median incision while preserving the integrity of the posterior ligamentous complex. In the treatment of single-level lumbar degenerative disease, M-MIDLIF has comparatively enhanced minimally invasive advantages over M-TLIF during the perioperative period while maintaining non-inferior clinical safety and efficacy relative to M-TLIF.
