OBJECTIVE: The C2 slope (C2S) is one of the parameters that can determine cervical sagittal alignment, but its clinical significance is relatively unexplored. This study aimed to evaluate the clinical significance of the C2S after multilevel cervical spine fusion. METHODS: A total of 111 patients who underwent multilevel cervical spine fusion were included in this study. The C2S, cervical sagittal vertical axis (cSVA), C2-7 lordosis, and T1 slope (T1S) were measured in standing lateral cervical

OBJECTIVE: To biomechanically compare the stress distribution of established posterior cervical fixation techniques-conventional pedicle screw (PS), Abumi technique, unicortical lateral mass screw (LMS), and bicortical LMS-with a novel PS method, the Lee point technique, using finite element modeling (FEM). METHODS: A patient-specific FEM of C5-6 was developed using high-resolution computed tomography scan data of a degenerative cervical spine. Five fixation models were constructed: Lee point, A

Purpose: To compare the 3-month outcomes of romosozumab and percutaneous vertebroplasty in patients with acute osteoporotic vertebral compression fractures (OVCFs). Background: Vertebroplasty provides rapid pain relief in acute OVCFs but carries risks such as cement leakage and adjacent fractures. Romosozumab, an anti-sclerostin monoclonal antibody, promotes bone formation and reduces fracture risk; however, its effectiveness in acute OVCFs remains unclear.Material and Methods: This retrospectiv

Purpose: This study compared the 3-month treatment effects of teriparatide and percutaneous vertebroplasty for acute osteoporotic vertebral compression fractures. Materials and Methods:A retrospective study was conducted on 76 patients diagnosed with acute osteoporotic vertebral compression fractures from January 1, 2020 to December 31, 2022.The patients were divided into the teriparatide group and the percutaneous vertebroplasty+alendronate group.The visual analog scale (VAS), Oswestry disabili

Effective recognition of worker actions on construction sites is critical for monitoring unsafe behaviors, ensuring workflow compliance, and analyzing productivity. Although computer vision has surpassed traditional manual observations by leveraging spatiotemporal features in videos, persistent challenges include recognition accuracy, generalization capability, and semantic comprehension in complex environments. Therefore, this paper proposes a domain-adapted vision-language fusion (DA-VLF) meth

Background/Objectives: The postoperative implications of a history of coronavirus disease 2019 (COVID-19) in patients undergoing spinal surgery remain inadequately defined. This study investigated whether a history of COVID-19 is associated with increased postoperative complication risk and assessed how surgical timing after infection influences outcomes. Methods: Patients who underwent spinal surgery in 2020 were identified. Individuals with a confirmed history of COVID-19 were matched 1:3 by a
