Study Design: Retrospective analysis of prospective multicenter adult spinal deformity (ASD) database.
Objective: To determine the prevalence and prognosis of postoperative coronal malalignment following LLIF for ASD with Qiu type A coronal alignment.
Summary Of Background Data: Qiu Type A coronal alignment is defined as coronal vertical axis (CVA) <30mm.
Incidence of revision surgery and patient-reported outcomes within 5 years of the index procedure for grade 1 spondylolisthesis: an analysis from the Quality Outcomes Database spondylolisthesis data.

Article Synopsis
- The study explores the impact of revision surgery on patient-reported outcomes (PROs) following initial surgeries for grade 1 spondylolisthesis, comparing decompression-only and decompression plus fusion (D+F) treatments.
- Data was collected from over 600 patients, revealing that 13.3% of decompression-only patients and 9.8% of D+F patients required revision surgery within 5 years, with revision patients reporting worse outcomes.
- The findings indicate that while revision surgery affects PROs adversely, patients undergoing D+F see a more significant decline in their reported outcomes compared to those who only had decompression surgery.
Article Synopsis
- The study aimed to explore the long-term effects of body mass index (BMI) on surgical outcomes in patients with low-grade lumbar spondylolisthesis, specifically comparing obese (BMI ≥ 35) and nonobese (BMI < 35) patients.
- Among 608 patients studied, those with a BMI ≥ 35 were generally younger, reported more severe pain and disability at baseline, and had a higher likelihood of requiring fusion surgery compared to their nonobese counterparts.
- Five years after surgery, no significant differences were found in readmission rates or reoperation rates between the BMI groups, although higher BMI was linked to lower chances of achieving important clinical improvements post-surgery.
Objective: Depression has been implicated with worse immediate postoperative outcomes in adult spinal deformity (ASD) correction, yet the specific impact of depression on those patients undergoing minimally invasive surgery (MIS) requires further clarity. This study aimed to evaluate the role of depression in the recovery of patients with ASD after undergoing MIS.
Methods: Patients who underwent MIS for ASD with a minimum postoperative follow-up of 1 year were included from a prospectively collected, multicenter registry.
Objective: There is a high prevalence of cervical myelopathy that requires surgery; as such, it is important to identify how different groups benefit from surgery. The American Association of Neurological Surgeons launched the Quality Outcomes Database (QOD), a prospective longitudinal registry, that includes demographic, clinical, and patient-reported outcome data to measure the safety and quality of neurosurgical procedures. In this study, the authors assessed the impact of gender on patient-reported outcomes in patients who underwent surgery for cervical myelopathy.

- The study aimed to compare the effectiveness of two surgical methods—anterior cervical discectomy and fusion (ACDF) vs. posterior cervical laminectomy and fusion (PCF)—for treating multilevel cervical spondylotic myelopathy (CSM).
- Researchers analyzed data from 199 patients across multiple sites and found similar rates of significant patient-reported outcomes 24 months post-surgery, with ACDF showing slightly better results.
- ACDF patients tended to be younger, had shorter hospital stays, and were less likely to experience long-term swallowing difficulties, although they had higher rates of postoperative dysphagia compared to those who underwent PCF.
Objective: Circumferential minimally invasive surgery (cMIS) may provide incremental benefits compared with open surgery for patients with increasing frailty status by decreasing peri- and postoperative complications.
Methods: Operative patients with adult spinal deformity (ASD) ≥ 18 years old with baseline and 2-year postoperative data were assessed. With propensity score matching, patients who underwent cMIS (cMIS group) were matched with similar patients who underwent open surgery (open group) based on baseline BMI, C7-S1 sagittal vertical axis, pelvic incidence to lumbar lordosis mismatch, and S1 pelvic tilt.
Objective: Previous studies have demonstrated the short-term radiographic and clinical benefits of circumferential minimally invasive surgery (cMIS) and hybrid (i.e., minimally invasive anterior or lateral interbody fusion with an open posterior approach) techniques to correct adult spinal deformity (ASD).

We aim to investigate the safety and efficacy of using a biplanar expandable cage in the treatment of symptomatic lumbar spondylolisthesis using a MIS TLIF approach.
Methods: A retrospective review of patient records was performed on patients who underwent MIS TLIF for symptomatic lumbar spondylolisthesis using the FlareHawk cage over a 12-month period.
