Minimally Invasive Transpedicular Screw Fixation: Review of 152 Cases in a Single Institution. Steep or Shallow Learning Curve?

The minimal muscle dissection and bone removal also will reduce complications attributed to blood clot accumulation and tissue fluid accumulation. 5 Several studies demonstrate statistically significant or highly significant reductions in intra-/perioperative blood loss in the MI-TLIF cohorts compared with their open TLIF groups ranging from mean values of 100 to 456 mL in the MI-TLIF cohorts versus 450 to 961 mL in the open TLIF group. 6 7 Villavicencio et al 2 reported lower estimated blood loss (163 mL) and shorter hospitalization (3 days) in MI-TLIF compared with open TLIF (366.8 mL and 4.2 days).
