Cadaveric study for ideal dorsal pedicle screw entry point
OBJECTIVE To determine the entry for the dorsal pedicular screw in relation to the notch present at the junction of base of the lateral margin of superior articular process with superior border of transverse process in dorsal spine. The advantage of this technique is a constant and easily identifiable entry point which does not involve partial resection of the inferior facet, thus maintaining s...
متن کاملTai 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 کاملSafety entry point, size and direction for placement of thoracic pedicle screw--a cadaveric study.
BACKGROUND Understanding of the pedicle anatomy is necessary for pedicle screw placement; however, there have been few Thai studies reporting on thoracic pedicle morphometry. OBJECTIVE To determine important anatomical measurements for thoracic pedicle screw fixation. MATERIAL AND METHOD T1-T12 vertebral pedicles were evaluated in 27 cadavers. The diameter angle, length and entry point of t...
متن کاملPrediction of scoliosis correction with thoracic segmental pedicle screw constructs using fulcrum bending radiographs.
STUDY DESIGN A retrospective series of 35 idiopathic scoliosis patients underwent spinal fusion with a segmental thoracic pedicle screw system. OBJECTIVE To evaluate the amount of scoliosis correction with segmental pedicle screw constructs, and assess whether the fulcrum bending radiograph can predict surgical correction. SUMMARY OF BACKGROUND DATA The fulcrum bending radiograph is highly ...
متن کاملThoracic pedicle screw placement: free-hand technique.
Thoracic pedicle screws provide a number of advantages over other methods of spinal fixation in treating a variety of conditions including: better pull-out strength and greater control in the sagittal, coronal and rotational planes due to increased stability to axial, bending and rotational forces by three-column fixation, fewer vertebral motion segments arthrodesed, no or lessened need for pos...
