Minimally invasive lumbar fusion surgery (MIS TLIF) has proven to be a favorable treatment for patients with spinal pathologies, in terms of short-term postoperative outcomes, compared to other surgical techniques. However, neurosurgeons and the global medical community are uncertain about the long-term effects of minimally invasive surgery on sagittal balance, and more specifically the influence of a lumbar fusion surgery on lordosis. One of the indicators of long-term success of lumbar fusion surgery is the preservation of lordosis, which is the inward curvature of the lumbar spine. Previous research has suggested that minimally invasive surgery may reduce the lordotic curve in the long run, and thus induces more nerve pain for the patient. The aim of this research is to conduct a retrospective study to investigate if MIS TLIF has a positive, negative, or neutral effect on lordosis by comparing patients’ preoperative and postoperative spinal parameter measurements, which include the pelvic incidence and the vertebral axis angles.
