Efficacy of Antibiotic-Loaded Cement Augmentation for Correcting Low Grade Pedicle Screw Loosening. [PDF]
Korean J Neurotrauma, 2021 Altered biomechanics and bone fragility can contribute to pedicle screw loosening. This study aimed to evaluate the efficacy of antibiotic-loaded cement augmentation for correcting symptomatic screw loosening as a minimally invasive alternative to open revision surgery.Ten consecutive patients who underwent percutaneous cement augmentation for pedicle ...

Value of standard radiographs, computed tomography, and magnetic resonance imaging of the lumbar spine in detection of intraoperatively confirmed pedicle screw loosening-a prospective clinical trial [PDF]
, 2019 BACKGROUND CONTEXT Pedicle screw loosening is common after spinal fusion and can be associated with pseudoarthrosis and pain. With suspicion of screw loosening on standard radiographs, CT is currently considered the advanced imaging modality of choice ...

S1 Pedicle Screw Loosening: A Systematic Review and Meta-Analysis of Risk Factors and Outcomes. [PDF]
Int J Spine SurgDespite advancements in fixation techniques, S1 pedicle screw loosening remains a common complication of lumbosacral fusion surgeries for degenerative lumbar conditions, with reported rates ranging from 15.6% to 41.9%. This complication can compromise fusion success, leading to nonunion, adjacent segment disease, and revision surgeries.

Finite element method study: the effect of insertion torque and angle on pedicle screw loosening [PDF]
, 2019 Pedicle screws are widely used for the treatment of spinal instability by spine fusion. This treatment can be performed at any level in the spine (cervical, thoracic or lumbar) and prevents any movement between the fused vertebrae.

Intraoperative biomechanics of lumbar pedicle screw loosening following successful arthrodesis [PDF]
Journal of Orthopaedic Research, 2016 Abstract Pedicle screw loosening has been implicated in recurrent back pain after lumbar spinal fusion, but the degree of loosening has not been systematically quantified in patients. Instrumentation removal is an option for patients with successful arthrodesis, but remains controversial. Here, we quantified pedicle
