Several techniques have been described for minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), offering varying degrees of direct visualization versus reliance on fluoroscopy. In addition, the techniques differ with respect to the extent of neural decompression, choice of fusion substrates, and methods for pedicle screw insertion. Here we classify and contrast these techniques and highlight the features of a recently-described technique known as modified miniopen TLIF (MOTLIF).
