Tai Chi pedicle screw placement for severe scoliosis.
STUDY DESIGN Retrospective. OBJECTIVE To evaluate the clinical safety and accuracy of the Tai Chi ((Equation is included in full-text article.)) technique for placing pedicle screws, without intraoperative radiographic imaging, in severe scoliotic spines. SUMMARY OF BACKGROUND DATA The current techniques for pedicle screw placement have a number of drawbacks in cases of severe scoliosis, in...
متن کاملIntraoperative 3-dimensional imaging (O-arm) for assessment of pedicle screw position: Does it prevent unacceptable screw placement?
BACKGROUND Pedicle screws are biomechanically superior over other spinal fixation devices. When improperly positioned, they lose this advantage and put adjacent structures at risk. Accurate placement is therefore critical. Postoperative computed tomography (CT) scans are the imaging gold standard and have shown malposition rates ranging from 2% to 41%. The O-arm (Medtronic Navigation, Louisvill...
متن کاملPedicle screw-rod fixation: a feasible treatment for dogs with severe degenerative lumbosacral stenosis
BACKGROUND Degenerative lumbosacral stenosis is a common problem in large breed dogs. For severe degenerative lumbosacral stenosis, conservative treatment is often not effective and surgical intervention remains as the last treatment option. The objective of this retrospective study was to assess the middle to long term outcome of treatment of severe degenerative lumbosacral stenosis with pedic...

OBJECTIVE To evaluate the accuracy and the effect of drill guide template for pedicle screw placement in severe scoliosis. METHOD Eight patients with rigid scoliosis were enrolled, five males and three females, ranging from nine to 23 years old. A three-dimensional CT scan of the spine was performed and saved as a DICOM file type. The multi-level template was designed by Mimics software and m...
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...
