Key Points

Lower incidence of radiologic adjacent segment pathology was observed with minimally invasive fusion techniques.
Findings indicate a reduced rate of complications arising from facet degeneration in minimally invasive procedures.
Assessment of sagittal balance during surgery is crucial for lowering risks associated with adjacent segment changes.
Minimally invasive approaches may enable more effective long-term spinal health, though further studies are needed.

Abstract

Minimally invasive fusion techniques that preserve posterior structures might slow the progression of degenerative changes in adjacent segments. To reduce R-ASP, preoperative assessment of facet degeneration and adequate restoration of sagittal balance during surgery are crucial considerations.
