PURPOSE: To examine if coronal deformity angular ratio (C-DAR) serves as a predictor for progression to surgical magnitude in patients with Adolescent Idiopathic Scoliosis (AIS) treated with thoracolumbar sacral orthosis (TLSO). METHODS: Patients with AIS, prescribed a full-time TLSO, Cobb angle 20-40°, Risser 0-2, who wore the brace ≥ 12.9 h and reached skeletal maturity/surgery were included retrospectively. C-DAR was defined as the Cobb angle divided by the number of vertebrae in the curve, yielding a larger value in short curves...

PURPOSE: Understanding idiopathic scoliosis (IS) natural history during growth is essential for shared decision-making between patients and physicians. We developed a retrospective model with the largest available sample in the literature and we aimed to investigate if using three peri-pubertal growth periods provides better prediction than a unique model. METHODS: Secondary analysis of a previous study on IS natural history data from radiographs before and at the first consult...

PURPOSE: To assess the effectiveness and safety of topical vancomycin powder (VP) in preventing surgical site infections (SSIs) in spinal deformity surgeries. METHODS: A literature search was conducted on Web of Science, PubMed, and Cochrane Library databases for comparative studies of VP in spinal deformity surgeries published before February 2024. Two reviewers independently screened eligible articles based on the inclusion and exclusion criteria, assessed study quality, and extracted data...

OBJECTIVE: Paralysis subsequent to spinal cord decompression in the cervical or thoracic region is infrequent, with White Cord Syndrome (WCS) being among its several causes. Due to WCS's infrequency, there exists a paucity of high-level evidence concerning its manifestations. Our primary objective is to systematically collate all documented WCS cases, discern prevalent risk and prognostic factors, appraise available treatment modalities, and evaluate patient outcomes. METHODS: A systematic review was conducted following PRISMA guidelines...

BACKGROUND: This study aimed to elucidate the specificity of the radiological features of Dropped head syndrome (DHS) from both reginal and global aspects. METHODS: We enrolled 53 patients with DHS (8 men, 45 women; mean age 73.5 years), and captured their lateral spinopelvic radiographs in standing position. We also selected 21 age- and sex-matched controls with cervical spondylosis. Radiological parameters were measured and compared between two groups. Compensatory and decompensatory sites were also listed for each patient...

PURPOSE: One of the major advantages of a minimally invasive microdiscectomy is that when CSF leak occurs, there is minimal anatomic dead space for ongoing leakage following removal of the tubular retractor. However, there are no published reports that address the safety and long-term outcomes of same-day discharge for CSF leak after tubular microdiscectomy. METHODS: This is a retrospective compartive study of 30 patients with incidental durotomy during minimally invasive tubular microdiscectomy occurring between January 1, 2009 to August 31, 2023 at our institution...

PURPOSE: Short-term efficacy of percutaneous kyphoplasty (PKP) for treating osteoporotic vertebral compression fracture (OVCF) in elderly patients is good, but long-term complications such as vertebral recompression (VRC) and adjacent vertebral fracture (AVF) may arise. Identifying risk factors in patients with poor prognoses, we developed a nomogram model to mitigate these potential complications. METHODS: Patients with OVCFs who underwent PKP had their medical data retrospectively evaluated...

PURPOSE: In patients with traumatic, infectious, degenerative, and neoplastic surgical indications in the cervical spine, commonly the anterior approach is used. Often these patients require a tracheostomy necessary due to prolonged mechanical ventilation. The limited spinal mobility and proximity to the surgical site of anterior cervical spine fixation (ACSF) could pose an increased risk for complications of percutaneous dilational tracheostomy (PDT.) Importantly, PDT might raise wound infection rates of the cervical spine approach...

PURPOSE: To compare the mechanical properties of human annulus fibrosus obtained by forceps versus bistoury and observe whether the measurement could be affected by forceps sampling method. METHODS: In this study, the mechanical properties of the the extracellular matrix (ECM) of human annulus fibrosus, including elastic modulus and stiffness, were investigated using atomic force microscope (AFM). Tissue was obtained from patients during operation using a bistoury or nucleus pulposus forceps...

PURPOSE: To investigate the clinical application of zonally magnified oblique multislice (ZOOM) imaging technology in patients with degenerative cervical myelopathy (DCM) and compare it with T2WI imaging. METHODS: A total of 111 patients diagnosed with DCM were recruited. According to mJOA, patients with DCM were divided into ND + group with neurological dysfunction and ND- group without neurological dysfunction. Routine MRI and ZOOM-DWI were performed on 3...

PURPOSE: The identification of gene mutations in the modern medical workup of metastatic spine tumors has become more common but has not been highly utilized in surgical planning. Potential utility of these genetic markers as surrogates for cancer behavior in current prognosis scoring systems and overall survival (OS) remains underexplored in existing literature. This study seeks to investigate the association of frequently identified tumor markers, EGFR, ALK, and PD-L1, in metastatic non-small cell lung cancer (NSCLC) to the spine with Tokuhashi prognosis scoring and OS...

PURPOSE: To evaluate the influence of preoperative VR-12 physical component scores (PCS) on outcomes following cervical disc replacement (CDR). METHODS: Patients undergoing elective CDR were retrospectively identified. Patient-reported outcomes (PROs) of interest included VR-12 PCS/VR-12 Mental Component Score (MCS)/9-Item Patient Health Questionnaire (PHQ-9)/Short Form-12 (SF-12) PCS and MCS/Patient-Reported Outcome Measurement Information System-Physical Function (PROMIS-PF)/Visual Analog Scale-Neck Pain (VAS-NP)/VAS-Arm Pain (VAS-AP)/Neck Disability Index (NDI)...

PURPOSE: This study aimed to evaluate the difference in treatment duration and unplanned additional surgeries between patients with unidentified causative organisms on empiric antibiotics and those with identified organisms on selective antibiotics in treating thoracolumbar pyogenic spondylitis with minimally invasive posterior fixation. METHODS: This multicenter retrospective cohort study included patients with thoracolumbar pyogenic spondylitis refractory to conservative treatment who underwent minimally invasive posterior fixation...

PURPOSE: While existing adult spinal deformity (ASD) alignment schemas acknowledge the dynamic relationship between the pelvis and spine, consideration of vertebral pelvic angles (VPA) thresholds for PJK may provide further insight into the relationship of each individual vertebra to the pelvis, which may allow for greater individualization of operative targets. Herein, we examine VPA's utility in preventing mechanical complications and its possible unification with prevalent scoring systems...

STUDY DESIGN: Narrative Review. OBJECTIVES: The premise of this review is to provide a review of the literature pertaining to studies describing outcomes of surgical cohorts when implementing C1 osteosynthesis for arch fractures with or without transverse atlantal ligamentous (TAL) injury. METHODS: A comprehensive search strategy was implemented across several search engines to identify studies which evaluate the outcomes of C1 osteosynthesis for patients with C1 arch fractures with and without TAL injury...

PURPOSE: The primary objective of this study is to evaluate and compare the clinical and radiographic outcomes of the combined spinous process-splitting approach with a Wiltse (SPSW) approach, the combined conventional approach with a Wiltse (CW) approach, and the conventional open (CO) approach in unilateral transforaminal lumbar interbody fusion (TLIF). METHODS: The clinical outcomes were assessed, and intraoperative data and complications were collected. Numeric Rating Scale (NRS) scores for low back pain and leg pain, the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) scores for evaluating functions of the lumbar spine and health-related quality of life, and the modified MacNab standard for assessing satisfaction were analyzed...
