Minimally Invasive Transforaminal Lumbar Interbody Fusion Surgery at Level L5-S1There are various techniques to obtain lumbar interbody fusion (LIF) at L5-S1 functional unit (FSU) level. This paper presents a finite element analysis to investigate the biomechanical changes caused by transforaminal ...
Visual analogue scale scores for back pain were significantly improved from 8.6+/-0.8 to 2.8+/-0.8 (P<0.0001) at 1 year.L5-S1 LAIF is feasible and safe with all the advantages of minimally invasive surgery. Fusion rates and pain improvement were comparable to those with an open repair. ...
Retrospective cohort study.#To assess whether the addition of L5-S1 anterior lumbar interbody fusion (ALIF) improves global sagittal alignment and fusion rates in patients undergoing multilevel spinal deformity surgery.#Two-year radiographic outcomes, including lumbar lordosis, pelvic incidence, pelvic til...

This most commonly occurs at the lumbosacral junction with L5 slipping over S1, but it can occur at higher levels as well. It is classified based on etiology into 5 types: dysplastic, defect in pars inter-articularis, degenerative, traumatic, and pathologic. The most common grading system for...
Accordingly, the less correction in L4 and L5 tilt would induce the immediate CM happening after correction surgery. Interestingly, the L4 and L5 tilt and their corrections perioperatively were not the risk factors for CM-developing during follow-up after multivariate analyzing. Buell et al. [16...
Three years after surgery, CT demonstrated fusion in one of five patients. CONCLUSION: Two years after endoscopic L5-S1 anterior lumbar interbody fusion using twin stand-alone laparoscopic carbon-fiber cages, the fusion rate was unacceptably low. However, the clinical outcomes of these patients were...
(Fusion group) were retrospectively compared.ResultsPreoperative grade for disc degeneration was not different between the two groups, and the most common operated segment had the most degenerated disc grade in both groups; L4-5 and L5-S1 in the Hybrid group, and L3-4 and L4-5 in Fusion ...
Seven patients had previous canal decompression surgery. Thirty-six patients underwent surgery at L4/5. The remainder underwent surgery at L5/S1 (n = 16) and L3/4 (n = 3). To evaluate the levels of lumbar and radicular pain, changes in pain density were recorded using a visual analogue ...
For the right-handed person, instrumentation in and out of the intervertebral space is best done through the right side of the patient, especially on the level L4/5 or L5/S1, because the working portal is located on the rostral side and on these levels the intervertebral space is tilted ...
