Abstract
Posterior lumbar interbody fusion (PLIF) is considered to be a suitable operative procedure for degenerative spondylolisthesis. However, PLIF is known as a procedure with many side effects; among them these related to the extensive invasion of paravertebral muscles (PVM) are the most remarkable. In order to overcome this problem with the aim being the prompt recovery of patients, we have recently conducted the MIS-TLIF (minimally invasive surgery-transforaminal lumbar interbody fusion), which is associated with less PVM insult. The procedure enables patients to rise, walk, leave the hospital, and return to their job promptly. MIS-TLIF is the combination of PLIF procedure using a percutaneous pedicle screw and rod system, CD Horizon Sextant, a bilateral decompression and a transforaminal interbody fusion by hemi mini-open approach using microendoscope or microscope. We reported comparative short-term outcomes after MIS-TLIF and conventional PLIF. MIS-TLIF technique was associated with longer surgical procedure. However, bed rest length and admission were shorter when compared with the conventional PLIF procedure. Concerning efficiencies of JOA score about low back pain differences were absent. There was a reduction in the low back pain on day 3 after MIS-TLIF procedure comparing to the preoperative period when evaluated through the VAS score. The MIS-TLIF is a less invasive procedure, which is associated with a reduction of the low back pain in the postoperative period that contributes to shorten the length of bed rest and admission. MIS-TLIF technique is a less insulting procedure for the treatment of degenerative spondylolisthesis.
