Comparison of Stand-alone Lateral Lumbar Interbody Fusion Versus Open Laminectomy and Posterolateral Instrumented Fusion in the Treatment of Adjacent Segment Disease Following Previous Lumbar Fusion Surgery

Study Design. Retrospective cohort study. Objective. The aim of this study was to compare clinical and radiographic outcomes of patients who underwent stand-alone lateral lumbar interbody fusion (LLIF) to those who underwent posterolateral fusion (PLF) for symptomatic adjacent segment disease (ASD). Summary of Background Data. Recent studies have suggested that LLIF can successfully treat ASD; however, there are no studies to date that compare LLIF with the traditional open PLF in this cohort. Methods. A total of 47 consecutive patients who underwent LLIF or PLF for symptomatic ASD between January 2007 and August 2016 after failure of conservative management were reviewed for this study. Patient-reported outcomes (PROs) were collected on all patients at preoperative, postoperative, and most recent post-operative visit using the Oswestry Disability Index, Visual Analog Scale (VAS)–Back, and VAS–Leg surveys. Preoperative, immediate postoperative, and most recent postoperative radiographs were assessed for pelvic incidence, fusion, intervertebral disc height, segmental and overall lumbar lordosis (LL). Symptomatic ASD was diagnosed if back pain, neurogenic claudication, or lower extremity radiculopathy presented following a previous lumbar fusion. Preoperative plain radiographs were evaluated for evidence of adjacent segment degeneration. Results. A total of 47 patients (23 LLIF, 24 PLF) met inclusion criteria. Operative times (P

BACKGROUND: Impaired balance is common in people with multiple sclerosis (MS) and can be present even in those with a mild disability level. With increasing disability, gait, and balance impairment progress, and lead to increased risk of falls. In some rec...

ConclusionsIn this multi-ethnic cohort from Toronto, Canada, blacks with NMOSD were less likely than Asians to demonstrate classic NMO by 2006 diagnostic criteria. Caucasians had better long-term disability outcomes compared to Asians as measured by the EDSS.

ConclusionLSS is frequent in lumbar scoliosis. Relationships exist between curve characteristics and symptomatic LSS in lumbar scoliosis; especially, concavity of the lumbosacral contra-curve and the junctional level between the lumbar curve and the lumbosacral contra-curve. Therefore, accurate analysis of stenosis in ASD seems mandatory, to at least perform decompression because perfect planned treatment for stenosis and scoliosis correction might not always be possible because of the patient's general health status.Level of EvidenceLevel 4.

Study Design. Prospective, cohort study. Objective. Demonstrate validity of Patient reported outcomes measurement information system (PROMIS) physical function, pain interference, and pain behavior computer adaptive tests (CATs) in surgically treated lumbar stenosis patients. Summary of Background Data. There has been increasing attention given to patient reported outcomes associated with spinal interventions. Historical patient outcome measures have inadequate validation, demonstrate floor/ceiling effects, and infrequently used due to time constraints. PROMIS is an adaptive, responsive National Institutes of Healt...

AbstractSurgical correction of fixed thoracolumbar deformity is usually achieved by estimating the preoperatively planned correction angles during surgery and is therefore prone to inaccuracy. This is particularly problematic in biplanar deformities. To overcome these difficulties, 3D model for planning, preparation, and simulation of an asymmetric pedicle subtraction osteotomy (aPSO) was printed and used to realign coronal and sagittal balance in case of rigid degenerative kyphoscoliosis. A 59-year-old woman presented with severe back pain and spinal claudication and was diagnosed with a rigid kyphoscoliosis with multilev...

Discussion: Five participants met criteria for having SLSS. Differences are reported in medians and interquartile ranges. Participants with SLSS reported more global pain, a greater number of comorbid conditions [SLSS: 7.0 (2.0) vs no-SLSS: 4.0 (2.0), P

This study aimed to investigate whether the restoration of disc dimensions would relieve symptoms of radiculopathy, claudication and back pain. In this retrospective study, patients undergoing XLIF surgery for relief of radicular symptoms or degenerative disc disease were included. Radiologically proven changes were used to assess the modes of degeneration. Objective measures such as the Visual Analogue Scale (VAS) for back and legs and the Oswestry Disability Index (ODI) were used. Complications were collated post-operatively from clinical notes and outpatient appointments. Twenty-three consecutive patients were included,...

Conclusions: Patients with smaller PI tended to be restored higher, and those patients with a larger PI were more likely to be restored lower. For patients with normal sagittal balance, the surgical outcomes in the treatment of low-grade lumbar degenerative spondylolisthesis with spinal fusion are not correlated with restoration of the LL.

The symptoms became more pronounced on sitting and walking, and conservative therapy was ineffective in relieving pain. Preoperative whole-spine X-ray scans revealed degenerative lumbar kyphoscoliosis. Asymmetrical pedicle subtraction osteotomy was performed and a convex-sided posterolateral wedge osteotomy was applied to correct the scoliosis and res...
