  • Cervical implant fixation: a topical review of techniques and their importance

    Cervical implant fixation is a critical surgical intervention for stabilizing the cervical spine, often necessitated by trauma, degenerative diseases, or spinal deformities. While spinal disc disease has historically been treated with fusion-based procedures, there has been a recent surge of interest in motion-preserving disc arthroplasties. The present study provides a topical narrative review of selected and recent literature on cervical implant fixation techniques, including anterior and posterior approaches, implant materials, biomechanical considerations, and reported clinical outcomes. Traditional fusion-based procedures have long been used to treat cervical disc disease, while recent years have seen increasing interest in motion-preserving techniques such as cervical disc arthroplasty. Developments in implant design and fixation strategies have contributed to improved radiographic and functional results compared with earlier systems, although each technique presents specific benefits and limitations. Cervical implant fixation has evolved into a highly sophisticated discipline that includes anterior, posterior, and motion-preserving techniques for treating a wide range of spinal conditions. This review summarises recent advances, common complications, and emerging trends in cervical fixation, and highlights existing research gaps to support future investigation and clinical decision-making.
  • Effect of pedicle-screw fixation on cervical spine: A comparative finite element analysis

    International Journal of Artificial Organs, 2026
    Background: Pedicle-screw-fixation (PSF) is a widely used surgical technique for stabilizing the cervical spine in cases of trauma, degenerative diseases and deformities. However, the biomechanical effects of PSF on cervical spine stability remain a topic of research. Objective: This study employs finite-element-analysis (FEA) to investigate the influence of PSF on the cervical spine under various loading conditions. Methods: A three-dimensional (3D) finite element model of the cervical spine (C2–C7) is developed, validated and subjected to simulated flexion, extension, lateral bending and axial rotation. Four scenarios are compared: (1) Intact spine (C2–C7), (2) spine with PSF at fourth segment (C4–C5), (3) spine with PSF at fifth segment (C5–C6) and (4) spine with two level PSF at fourth and fifth segments (C4–C6). Results: The results demonstrate that due to single segment PSF, the total ROM (second to sixth segments) is reduced by 8.8%, 8.5%, 12.4% and 11.4% whereas two segment PSF shows that the total ROM is reduced by 24.2%, 23.3%, 23.5% and 25.3% under 1 N-m flexion, extension, lateral bending and rotations, respectively, in comparison to intact cervical spine. The maximum stresses on Titanium alloy (Ti-6Al-4V) Pedicle-screw are varied from 70 to 75 MPa and on PEEK rod are around 32–40 MPa, respectively. The maximum stresses on pedicle-screw and rod material are also below its yield stress. Conclusion: This present FE study provides the biomechanical efficacy of cervical PSF and its impact on spinal stability for restoring cervical spine biomechanics.
  • A comparison of rigid, semi-rigid and flexible spinal stabilization devices: A finite element study

    Pedicle-screw-based spinal fixation system has shown its success for treating degenerative disc disease-related back pain and spinal instability. In the last few decades, several non-fusion implants ( ‘flexible’ or ‘dynamic’ fixation) are developed for treating slight degenerate disc disease. The aim of this study is to characterize and compare the biomechanical responses of pedicle-screw-based fusion with various rod materials and a flexible spinal stabilization device on the lumbar spine (L3L5). Computed tomography scan-based finite element model and pedicle screw fixation with rigid rod material stainless steel rod, semi-rigid rod material poly-ether-ether-ketone and flexible rod device made of stainless steel are used in this study. Intact model of the lumbar spine and treated with all the different implants are simulated under typical physiological loading conditions. Compared with the intact model, pedicle screw with the stainless steel rod fixation system is found to offer very less range of motion. Poly-ether-ether-ketone rod system increased range of motion 3.8, 7 and 1.8 times for axial rotation, lateral bending and flexion–extension, respectively, compared to the stainless steel rod system. The flexible rod device rod system is found to reduce stress on vertebral body, carrying out more loads as compared to poly-ether-ether-ketone rods. In the case of stainless steel rods, range of motion is almost restricted on the fusion zone, which is overcome by the poly-ether-ether-ketone rod system to some extent and farther improved by the flexible rod device rod system. So, the poly-ether-ether-ketone rod and flexible rod device rod systems may be implemented for better clinical results after succeeding experimental validation and clinical trial.
