Restoration of lordosis and disk height after single‐level transforaminal lumbar interbody fusion

Abstract

Intervertebral height and lumbar lordosis reconstruction are important for achieving good surgical results; guidance regarding the likely changes in lumbar lordosis and disk height after TLIF is provided by our findings.

Restoration of the spinopelvic sagittal balance in isthmic spondylolisthesis: posterior lumbar interbody fusion may be better than posterolateral fusion

“…According to the change of SS, the ideal LL should increase. Kepler et al [43] evaluated the surgical outcome with a visual analog scale; they found the patients with low LL had more probability to suffer low back pain.…”

Do position and size matter? An analysis of cage and placement variables for optimum lordosis in PLIF reconstruction

“…Posterolateral placement within the intervertebral space, where the endplate is thicker [8] and stronger [8,26], has been suggested following a biomechanical study assessing the risk of cage subsidence [14], whereas central placement has shown greater subsidence in a clinical study [15]. With regard to anterior placement, both a cadaveric [27] and a clinical study [28] involving TLIF found no difference in intervertebral lordosis when cages were placed in the anterior half of the disc space. However, the surgical technique in both studies did not involve bilateral total facetectomies and excision of adjacent spinous processes, nor did they aim for extreme anterior placement, so this may have limited the final lordosis achieved.…”

Clinical and radiographic outcomes of concentrated bone marrow aspirate with allograft and demineralized bone matrix for posterolateral and interbody lumbar fusion in elderly patients

“…Complications assessed include infection, pseudarthrosis, hardware-related complications and graft donor site morbidities. Clinical outcomes were assessed based on a 4-grade system: excellent, good, satisfactory and poor, in accordance with the modified Odom's criteria [21].…”
