Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) in treatment of degenerative diseases of lumbosacral spine compared to modified open TLIF: a prospective randomised controlled study

Clinical and radiological outcomes after MIS TLIF in patients with degenerative disease of the lumbosacral region are generally favourable. MIS TLIF was associated with decreased blood loss perioperatively, a lower radiation dose and an earlier discharge, but there was no difference between MIS TLIF and modified open TLIF in 48-month outcomes in terms of disability, back pain, leg pain, quality of life, or patient satisfaction rate or complication rate. Although the differences taper off over time, MIS TLIF has undeniable advantages in the perioperative and early postoperative periods.
