C2 Pedicle Screw Placement: A Novel Teaching Aid
The C2 pedicle screw is more biomechanically stable and provides patients with increased postoperative range of motion in comparison to other methods of C2 fixation. However, as a result of the proximity of the C2 pedicle to the transverse foramen, there is a considerable risk of intraoperative morbidity due to vertebral artery injury laterally or vertebral canal breach medially. Other than the...
متن کاملStrategy for salvage pedicle screw placement: A technical note
BACKGROUND Salvage surgery for failed lumbar spine fusion with a loosened pedicle screw is challenging. In general, the strategy includes replacement with larger and longer pedicle screws, augmentation with polymethylmethacrylate cement or hydroxyapatite granules, and extension of fused segments. The purpose of this study is to introduce a new technique for pedicle screw replacement after faile...
متن کاملPedicle screw placement in patients with variant atlas pedicle
OBJECTIVE To investigate how the anatomy of variant atlas vertebra impacts on the strategy used to place pedicle screws used to treat atlantoaxial instability. METHODS The study enrolled patients with cervical instability who had a posterior arch pedicle height <3.5 mm at the anchor point, a vertebral artery groove height <3.5 mm, or both. Pedicle screws were fitted according to the anatomy o...
متن کاملSurgical treatment of odontoid fractures with C1 hook and C2 pedicle screw construct.
A number of approaches have been attempted to address the treatment of acute odontoid fractures, spanning from conservative treatment with an external orthotic device to posterior C1-C2 arthrodesis or anterior screw fixation. The current report describes stabilisation of such fractures with a C1 supralaminar hook and a C2 pars interarticularis screw construct. Two patients with odontoid fractur...
متن کاملDetermining Optimal C2 Pedicle Screw Placement and Length in Patients with Axis Traumatic Spondylolisthesis: A Case Series
We sought to determine the optimal placement and screw length for C2 pedicle screw fixation to compare with recommendations in literature. Nine patients were included in this study and underwent C2 pedicle instrumentation either for a hangman's fracture as part of C2 pedicle-C3 lateral mass fixation or for C2-C3 subluxation. All nine patients had good postoperative improvement with satisfactory...
