Laterally Placed Expandable Interbody Spacers Improve Radiographic and Clinical Outcomes: A 1-Year Follow-up Study

This study describes the clinical and radiographic outcomes of patients treated with expandable interbody spacers for MIS LLIF.MethodsA retrospective, single surgeon, clinical and radiographic study was performed on 37 consecutive patients who underwent MIS LLIF at 1–2 contiguous level(s) using expandable spacers. Radiographic and clinical functional outcomes were collected and compared at preoperative and postoperative time points up to 12 months. Parametric and nonparametric tests were used when appropriate with p value

AbstractPurposeThree-column osteotomies at L5 or the sacrum (LS3COs) are technically challenging, yet they may be needed to treat lumbosacral kyphotic deformities. We investigated radiographic and clinical outcomes after LS3CO.MethodsWe analyzed 25 consecutive patients (mean age 56  years) who underwent LS3CO with minimum 2-year follow-up. Standing radiographs and health-related quality-of-life scores were evaluated. A new radiographic parameter [“lumbosacral angle” (LSA)] was introduced to evaluate sagittal alignment distal to the S1 segment.ResultsFrom preoperatively to the final follow-up, significant i...

Study Design. Retrospective review of a prospectively collected database. Objective. To define a simplified singular measure of cervical deformity (CD), C2 slope (C2S), which correlates with postoperative outcomes. Summary of Background Data. Sagittal malalignment of the cervical spine, defined by the cervical sagittal vertical axis (cSVA) has been associated with poor outcomes following surgical correction of the deformity. There has been a proliferation of parameters to describe CD. This added complexity can lead to confusion in classifying, treating, and assessing outcomes of CD surgery. Methods. A prospectiv...

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 Augus...

Conclusions: PROMIS physical health domains were related to the Ames CD classification. Certain BL PROMIS thresholds can be connected to the severity of CD.

Conclusions: The results of minimally invasive thoracoscopic PTKC using an expandable cage were satisfactory. The majority of the patients were satisfied after treatment and no neurological complications occurred. Functional and QOL scores were fairly good. Whereas some postoperative kyphosis correction was lost over time, bony fusion was achieved in the majority of the patients. The thoracoscopic approach minimizes surgical morbidity, does not lead to serious complications, and provides a good option for PTKC. PMID: 31679324 [PubMed - as supplied by publisher]

This study examines the timing of clinical improvement and identifies factors (including spinal alignment) associated with worse outcomes. METHODS: Consecutive adult patients were enrolled in a prospective outcomes database from two academic centers participating in the Quality Outcomes Database from 2013 to 2016. Demographics, surgical details, radiographic data, arm and neck pain (visual analog scale [VAS] scores), and disability (Neck Disability Index [NDI] and EQ-5D scores) were reviewed. Multivariate analysis was used. RESULTS: A total of 186 patients were included, and 48.4% were male. Their mean age was 55...

ConclusionOur meta-analysis suggested that long fusion terminating at L5 or the sacrum was similar in scoliosis correction, overall complication rate, revision rate, and improvement in pain and disability. However, fusion to L5 had advantages in lower rate of pseudarthrosis, implant-related complications, and proximal adjacent segment disease, while fusion to the sacrum had advantages in the restoration of lumbar lordosis, maintenance of sagittal balance, and absence of distal adjacent segment disease.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

Study Design. A nonrandomized, prospective, and single-center clinical trial. Objective. The aim of this study was to investigate the clinical and radiographic efficacy of ProDisc Vivo cervical total disc replacement (cTDR) in patients with clinical and radiographic documented cervical spondylotic myelopathy (CSM), due to degenerative changes at the index level. Summary of Background Data. Decompression and fusion is still the gold standard in patients with cervical myelopathy. Very limited data are available regarding the application of cTDR in patients with clinical and radiological documented CSM in context of c...

CONCLUSIONS: This study further refines the generally accepted LL = PI + 10° by showing that patients under the age of 50 years should have more LL compared to PI, whereas after the 5th decade the relationship is reversed. SVA was not as sensitive across age groups, exhibiting a marked increase only in the 7th decade of life. Given the reliable increase of CL with age, and the stability of T1 slope/CL, this represents another important relationship that should be maintained when performing cervical deformity/fusion surgery. This study has important implications for evaluating adult patients with spinal deformities and ...

Sagittal imbalance in the cervical spine is a major cause of neck pain, headache, fatigue, and disability. While parameters such as C2-C7 lordosis and C2-C7 sagittal vertical axis have been extensively studied, they do not fully characterize cervical sagittal balance. T1 is an important new parameter of both cervical as well as global spinal sagittal balance. However, the T1 superior end plate can be difficult to visualize on standard lateral radiographs due to overlying anatomical structures. C7 slope has therefore been proposed as a potential substitute for T1 slope when the T1 superior end plate is not well visualized.
