STUDY DESIGN: Retrospective Study. OBJECTIVES: Minimally invasive endoscopic spinal surgery is gaining popularity, but our understanding of the lumbar spine's microvascular geometry relies heavily on cadaver studies and textbook illustrations. Additionally, inconsistent nomenclature of vessels in the literature hampers effective communication among surgeons. This study aims to improve the clarity and comprehensibility of the lumbar spinal microvascular geometry under endoscopic view...

STUDY DESIGN: A retrospective analysis of oncologist-provided prognoses vs actual survival outcomes of patients referred with Metastatic spinal cord compression (MSCC) to a supra-regional multidisciplinary team (MDT). OBJECTIVES: Prognostic scoring systems, such as the revised Tokuhashi, are commonly used to help guide the treatment of MSCC. However, scoring systems do not accommodate for the improved outcomes of contemporary cancer therapy. Oncologist-provided prognoses play an important role in real world rapid decision making...

STUDY DESIGN: Systematic Review. OBJECTIVES: To determine the efficacy and overall outcomes of iFactor/ABM/P-15 following lumbar spine surgery. METHODS: We performed a search of the Cochrane Library, Medline Ovid, PubMed, and SCOPUS databases from inception until August 2023. Eligible studies included outcomes of patients receiving iFactor following lumbar spine surgery. The primary outcomes of interest were fusion rates and iFactor efficacy after lumbar surgery in patients who received iFactor...

We propose that the key to improving care for these patients is to truly understand the processes that take place from the interpretation of radiographic findings, through the assessment of the severity of various injuries, to inclusion within a classification category and finally to selecting a specific treatment.

STUDY DESIGN: Retrospective case series. OBJECTIVE: To the best of our knowledge, the prevalence of lumbar spondylolysis in white and black populations has never been studied using computed tomography (CT). The purpose of this study was to examine and compare the prevalence and characteristics of lumbar spondylolysis in white and black patients. METHODS: This study is a cross sectional study. Patients aged 20-79 who underwent abdominal and pelvic CT for trauma screening in the New York City area and whose race was classified as "white" and "black" on the questionnaire were recruited to the study...

STUDY DESIGN: Retrospective cohort. OBJECTIVE: To compare the characteristics of the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) metrics when interpreting Neck Disability Index (NDI) following cervical spine surgery. METHODS: Patients who underwent primary cervical fusion, discectomy, or laminectomy were included. NDI and global rating change (GRC) data at 6 months/1 year/2 years were analyzed...

STUDY DESIGN: Cadaveric anatomical studies. OBJECTIVE: This study aims to investigate the anatomical relationship between bony landmark "V point", dural sac, nerve roots, and intervertebral disc for improving operative outcomes and decreasing post-operative complications in posterior endoscopic cervical foraminotomy or discectomy (PECF or PECD). METHOD: 10 soft adult cadavers were studied. We measured the distance of the V point to the lateral margin of dural sac, V point to the inferior border of intervertebral disc, and the inferior border of cervical nerve root to the inferior border of intervertebral disc...

STUDY DESIGN: Clinical study. OBJECTIVE: Our work was aimed at exploring the expression and clinical significance of microRNA-138-5p (miR-138-5p) and Transforming Growth Factor-beta 3 (TGF-β3) in peripheral blood of patients with ankylosing spondylitis (AS). METHODS: Forty-seven patients with AS were selected as the AS group, and the staging of the enrolled AS patients was based on the BASDAI score: <4 points were classified as the stable stage (stable group) and ≥4 points were classified as the active stage (active group)...

STUDY DESIGN: Retrospective multicenter study. OBJECTIVES: To investigate the treatments of the geriatric population with hangman's fractures using a multicenter database under the Japan Association of Spine Surgeons with Ambition (JASA). METHODS: The multicenter database included data from 1512 patients. We employed the Levine and Edwards classification for categorizing hangman's fractures. The study incorporated epidemiological data, including the prevalence of hangman's fractures, patient age, and follow-up duration...

STUDY DESIGN: Retrospective Cohort Study. OBJECTIVES: This study aimed to examine the effect of state legislation on prescribing behavior after a commonly performed spinal procedure, posterior lumbar interbody fusion (PLIF). METHODS: Two cohorts of patients from the Pearl Diver Database were created based on patients who underwent PLIF surgery in 2014-15 and 2018-19. We compared opioid prescription rates and morphine-milli-equivalent (MME) between states with and without prescription legislation...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of this study was to see whether upgrades in newer generation robots improve safety and clinical outcomes following spine surgery. METHODS: All patients undergoing robotic-assisted spine surgery with the Mazor X Stealth EditionTM (Medtronic, Minneapolis, MN) from 2019 to 2022 at a combined orthopedic and neurosurgical spine service were retrospectively reviewed. Robot related complications were recorded...

STUDY DESIGN: Retrospective database analysis. OBJECTIVE: Polytraumatized patients with spinal injuries require tailor-made treatment plans. Severity of both spinal and concomitant injuries determine timing of spinal surgery. Aim of this study was to evaluate the role of spinal injury localization, severity and concurrent injury patterns on timing of surgery and subsequent outcome. METHODS: The TraumaRegister DGU® was utilized and patients, aged ≥16 years, with an Injury Severity Score (ISS) ≥16 and diagnosed with relevant spinal injuries (abbreviated injury scale, AIS ≥ 3) were selected...

STUDY DESIGN: Retrospective study. OBJECTIVES: We investigated the effect of corridor width on the postoperative outcomes of patients who underwent the OLIF procedure. METHODS: Patients who underwent OLIF surgery, which included L4-5, between 2015 and 2021 were retrospectively studied. The patients were divided into three groups by the width of the corridor: not more than 10 mm, between 10 and 20 mm, and 20 mm or more. We compared clinical and radiographic outcomes and complications between these groups...

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: In patients undergoing elective anterior cervical discectomy and fusion (ACDF), we sought to determine the impact of screw length on: (1) radiographic pseudarthrosis, (2) pseudarthrosis requiring reoperation, and (3) patient-reported outcome measures (PROMs). METHODS: A single-institution, retrospective cohort study was undertaken from 2010-21. The primary independent variables were: screw length (mm), screw length divided by the anterior-posterior vertebral body diameter (VB%), and the presence of any screw with VB% < 75% vs all screws with VB% ≥ 75%...

STUDY DESIGN: Multicenter comparative cohort. OBJECTIVE: Studies have shown markedly higher rates of complications and all-cause mortality following surgery for adult cervical deformity (ACD) compared with adult thoracolumbar deformity (ATLD), though the reasons for these differences remain unclear. Our objectives were to compare baseline frailty, disability, and comorbidities between ACD and complex ATLD patients undergoing surgery. METHODS: Two multicenter prospective adult spinal deformity registries were queried, one ATLD and one ACD...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Cavernous malformations (CMs) and hemangioblastomas (HBs) of the spinal cord exhibit distinct differences in histopathology but similarities in the neurological course. The aim of our study was to analyze the clinical differences between the vascular pathologies and a benign tumor of the spinal cord in a perioperative situation. METHODS: We performed a retrospective analysis of patients who had undergone surgery for lesions in the spinal cord between 1984 and 2015...

STUDY DESIGN: Retrospective review of prospective data. OBJECTIVES: Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) may be beneficial for elderly patients due to decreased surgical morbidity and faster postoperative recovery. This study compared the clinical and radiological outcomes of MIS-TLIF in elderly patients and younger controls at minimum 5-year follow-up. METHODS: There were 120 patients who underwent single-level MIS-TLIF for degenerative spondylolisthesis...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To build a predictive model for risk factors for failure of radiation therapy, hypothesizing a higher SINS would correlate with failure. METHODS: Patients with spinal metastasis being treated with radiation at a tertiary care academic center between September 2014 and October 2018 were identified. The primary outcome measure was radiation therapy failure as defined by persistent pain, need for re-irradiation, or surgical intervention...
