Transforaminal lumbar interbody fusion (TLIF) and unilateral transpedicular fixation.

چکیده
TLIF (transforaminal lumbar interbody fusion) is a method of interbody fusion, which is alternative to other vertebral fusion wherein, with an approach through intervertebral foramen, through lateral segment of intervertebral space, complications occurring with other methods are reduced. Today, there are numerous versions of this method in terms of implants and transplants. At our Department patients with axial pain resistant to conservative treatment of minimum six months underwent TLIF method with unilateral transpendicular fixation with polyaxial screws, CAGE filled with autologous transplant obtained by lamina resection, and posteromedial contralateral fusion. 22 procedures were performed at 22 levels, 10 for relapsing hernia, and 12 for disc herniation combined with degenerative changes on the same level. Pain reduction was significant; according to VAS score, lumbar pain was reduced from preoperative 8.5 +/- 0.8 to 2.4 +/- 0.85 (-72.63%) a year after, and leg pain was reduced significantly from preoperative 8.45 +/- 0.91 to 2.072 +/- 0.81 (71%) 12 months after surgery. The Wilcoxon paired test demonstrated a significant difference between preoperative VAS score and the value measured 12 months after surgery (n = 22, Z = 4.1, p < 0.001) leg and back, respectively. In 15 (68.2%) patients fusion was evidenced on standard X-ray of lumbar spine, and in 4 patients, with aggravated clinical presentation, fusion in 2 patients and pseudoarthrosis in 2 patients were evidenced by CT. Total 17 patients (77.3%) showed signs of fusion. In our study we demonstrated that unilateral ipsilateral transpedicular fixation, with positioning of one CAGE filled with local autologous transplant represents a reliable and successful method of treatment of axial lumbar pain.

Minimally Invasive Transforaminal Lumbar Interbody Fusion with Unilateral Pedicle Screw Fixation: Comparison between Primary and Revision Surgery
Minimally invasive surgery with a transforaminal lumbar interbody fusion (MIS TLIF) is an important minimally invasive fusion technique for the lumbar spine. Lumbar spine reoperation is challenging and is thought to have greater complication risks. The purpose of this study was to compare MIS TLIF with unilateral screw fixation perioperative results between primary and revision surgeries. This ...

BACKGROUND A few studies focused on unilateral or bilateral pedicle screw (PS) fixation of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) to treat lumbar degenerative diseases have been published. There is still debate over whether one method is superior to another. A systematic review and meta-analysis of randomized controlled trials (RCT) was performed to compare the eff...

This study investigates the biomechanical stability of a large interbody spacer inserted by a lateral approach and compares the biomechanical differences with the more conventional transforaminal interbody fusion (TLIF), with and without supplemental pedicle screw (PS) fixation. Twenty-four L2-L3 functional spinal units (FSUs) were tested with three interbody cage options: (i) 18 mm XLIF cage, ...

PURPOSE Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is increasingly popular for the surgical treatment of degenerative lumbar disc diseases. The constructs intended for segmental stability are varied in MI-TLIF. We adopted finite element (FE) analysis to compare the stability after different construct fixations using interbody cage with posterior pedicle screw-rod or ped...
