Modified paravertebral foramen screw trajectory for posterior cervical spine fixation: feasibility of computed tomographic evaluation
mPVFS provides a biomechanical advantage by increasing screw length and contact area while targeting dense cancellous bone. mPVFS could safely accommodate screws that are 2.5-3.0 mm longer than conventional PVFS, irrespective of patient age or sex, which may be a potential clinical advantage. To validate its efficacy and long-term stability, further biomechanical and clinical studies are required.
