Anand N, Baron EM, Khandehroo B. Administrative/technical/material support: all authors. Multivariate linear regression was performed to identify independent correlates with the primary outcome of interest (change in SL). 2018;29(3):399–406. 2017;26(11):2843–2850. No matter where a patient is in the degenerative cascade, Centinel Spine's broad array of anterior spinal products can help. This relationship has been demonstrated regardless of the indication for surgery or the surgical approach.1,2 Specifically, in minimally invasive surgery (MIS) techniques performed for degenerative lumbar conditions, the interbody cage being used is often the sole driver of postoperative lordosis.3,4 Despite the reported advantages of interbody devices in MIS fusion surgery (increased surface area for fusion, restoration of disc height, indirect foraminal decompression), MIS interbody fusions have been associated with a “flattening effect” in the lumbar spine, putting patients at risk for suboptimal postoperative alignment and poor outcomes.5,6 To overcome such deficiencies, MIS surgeons will often use an interbody cage that has been manufactured with a greater amount of “built-in” lordosis. The cages can be inserted through a small incision (minilaparotomy) or with an endoscope (a scope that allows the surgery to be done through several one-inch incisions). Generally, the maximum available cage lordotic angle was chosen, provided that the cage trialing was acceptable and did not appear to risk endplate violation. Values are presented as degrees. The change in SL was highest after ALIF (average increase 9.8° in SL vs 1.8° in TLIF vs 1.8° in LLIF, p < 0.001). 1999-2020 Veritas Health, LLC. A retrospective review was performed of a single-surgeon database of adult patients (age 18–80 years) who underwent primary instrumented LIF between April 2017 and December 2018 for degenerative lumbar conditions.14 Procedures were performed using contemporary MIS techniques, including transforaminal LIF (TLIF), lateral LIF (LLIF), and anterior LIF (ALIF) approaches. 2020;16(1):46–53. interbody space.” The large windows used for graft packing also allow At L4-L5, there is more flexion/extension motion, and this allows more motion through the cages. J Neurosurg Spine. Based on the sample criteria, 130 patients were retrieved from the database and 32 were excluded, leaving 98 patients (116 surgical levels) available for analysis. to a spacer allows the surgeon to have the interbody device take part in Mean values are presented ± SD. © Copyright 1944-2020 American Association of Neurological Surgeons, TLIF = transforaminal lumbar interbody fusion, The impact of age on surgical goals for spinopelvic alignment in minimally invasive surgery for adult spinal deformity, Age-adjusted alignment goals have the potential to reduce PJK, Restoration of lumbar lordosis after minimally invasive transforaminal lumbar interbody fusion: a systematic review, Retrospective review of immediate restoration of lordosis in single-level minimally invasive transforaminal lumbar interbody fusion: a comparison of static and expandable interbody cages, Clinical and radiographic parameters associated with best versus worst clinical outcomes in minimally invasive spinal deformity surgery, Comparison of radiographic results after minimally invasive, hybrid, and open surgery for adult spinal deformity: a multicenter study of 184 patients, Lordosis recreation in transforaminal and posterior lumbar interbody fusion: a cadaveric study of the influence of surgical bone resection and cage angle, The current state of minimally invasive approaches to adult spinal deformity, Perioperative outcomes in minimally invasive lumbar spine surgery: A systematic review, Using minimally invasive techniques adds to the value equation for select patients, Anterior column realignment has similar results to pedicle subtraction osteotomy in treating adults with sagittal plane deformity, Do position and size matter?
