Surgical outcomes with anatomic reduction of high-grade spondylolisthesis revisited: an analysis of 101 patients

J Neurosurg Spine. 2021 Sep 17:1-11. doi: 10.3171/2021.3.SPINE202091. Online ahead of print.ABSTRACTOBJECTIVE: The ideal strategy for high-grade L5-S1 isthmic spondylolisthesis (HGS) remains controversial. Critical questions include the impact of reduction on clinical outcomes, rate of pseudarthrosis, and postoperative foot drop. The scope of this study was to delineate predictors of radiographic and clinical outcome factors after surgery for HGS and to identify risk factors of foot drop.METHODS: This was a single-center analysis of patients who were admitted for HGS, defined as grade III or greater L5 translation according to the Meyerding (MD) classification. Complete postoperative reduction was defined as MD grade I or less and L5 slip

Conclusion. Decompression and DS surgery for LSS with or without spondylolisthesis showed favorable long-term surgical outcomes with an acceptable rate of complications and ASD. However, an improved physiological DS system should be developed. Level of Evidence: 4

Online ahead of print.ABSTRACTOBJECTIVE: The goal of this study was to evaluate the clinical and radiographic outcomes of a novel multidirectional in situ expandable minimally invasive surgery (MIS) transforaminal lumbar interbody fusion (TLIF) cage.METHODS: A retrospective analysis of 69 consecutive patients undergoing a 1- or 2-level MIS TLIF using an expandable cage was performed over a 2-year period. Standard MIS techniques with pedicle screw fixation were used in all cases. Upright lateral dynamic flexion/extension radiographs were reviewed prior to ...

Abstract OBJECTIVE: The purpose of this study was to compare the preoperative radiographic features of degenerative lumbar spondylolisthesis (DLS) with and without local coronal imbalance (LCI) and to investigate the surgical outcomes of transforaminal lumbar interbody fusion (TLIF) in the treatment of DLS with LCI at the spondylolisthesis level. DLS with scoliotic disc wedging and/or lateral listhesis at the same involved segment, as well as LCI, constitutes a distinct subgroup. However, previous studies concerning surgical outcomes focused mainly on sagittal profiles. There is a paucity of valid data regarding l...

Abstract OBJECTIVE: The main purpose of selective dorsal rhizotomy (SDR) is to reduce spasticity in the lower extremities of children diagnosed with cerebral palsy (CP) and spastic diplegia. The potential for developing spinal abnormalities and pain is a concern, especially in the aging CP population. Therefore, the aim of this study was to evaluate spinal abnormalities, level of pain, and disability (due to back or leg pain) in adults with CP, and associations with participant characteristics, more than 25 years after SDR. METHODS: This is a 9-year follow-up study with data collection conducted in 2008 and 2...

Cervical spondylolisthesis indicates instability of the spine and can lead to pain, radiculopathy, myelopathy and vertebral artery stenosis. Currently degenerative cervical spondylolisthesis is a wait-and-watch condition with no treatment guidelines. A literature review and discussion will be provided. 8 females presented with neck pain, disability, and history of motor vehicle collision. Radiographs revealed abnormal cervical alignment, spinal canal narrowing, and spondylolistheses. After 30 sessions of Chiropractic BioPhysics ® care over 12 weeks, patients reported improved symptoms and disabilities. Radiographs reve...

No information on clinical impact or outcome is available.PurposeTo determine the prevalence of this pathology and to investigate its affect on the course of adolescent idiopathic scoliosis (AIS).MethodsA retrospective comparative study using patients ’ records, radiographs, the national inpatient registry, and Patient-rated outcome measures (PROM): Oswestry disability index (ODI), modif.SRS-24 questionnaire, WHO-Quality of life index (WHOQoL), Numerical rating scale (NRS) for pain. Clinical follow-up time was 4.4 (4.3) years, and ...

This study included 65 patients with lumbar spondylolisthesis, who underwent either open transpedicular screw fixation (OTPSF) with posterior lumbar interbody fusion (PLIF) (OTPSF group, n = 33) or PPSF with reduction system (PPSFr group, n = 32) after PLIF. The slippage degree (SD); the intervertebral disc height (IDH); lumbar lordosis (LL); and segmental angle (SA) were measured on the follow-up simple lateral radiographs. For pain and functional assessment in patients, visual analogue scale (VAS) scores for low back pain and leg pain, and Oswestry Disability Index (ODI) scores were measured. SA (P

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.

Conclusions: Both PLF and PLF+TLIF are effective fusion methods for L4/5 stenosis and spondylolisthesis. In this study, patients treated with PLF were less likely to undergo a subsequent lumbar surgery. More research is needed to determine which factors influence whether PLF or PLF+TLIF should be used in these patients. Level of Evidence: Level III.
