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 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 کاملBiomechanical Analysis of an S1 Pedicle Screw Salvage Technique via a Superior Articulating Process Entry Point.
STUDY DESIGN Biomechanical, cadaveric study. OBJECTIVE To compare the fixation strength of a novel S1 pedicle screw insertion technique in a revision setting to a standard S1 pedicle screw and an L5 pedicle screw. SUMMARY OF BACKGROUND DATA Fusions to the sacrum remain a difficult clinical challenge. Very few salvage techniques exist when a nonunion occurs. METHODS The biomechanical integ...
متن کاملAccuracy of Pedicle Screw Placement with Robotic Guidance System: A Cadaveric Study.
STUDY DESIGN A cadaveric study. OBJECTIVE To investigate the accuracy of pedicle screw placement using a robotic guidance system (RGS). SUMMARY OF BACKGROUND DATA RGS is a unique surgery assistance-apparatus. Although several clinical studies have demonstrated that RGS provides accurate pedicle screw placement, very few studies have validated its accuracy. METHODS A total of 216 trajector...
متن کاملNovel Landmark for Cervical Pedicle Screw Insertion Point from Computed Tomography-Based Study
STUDY DESIGN Cross-sectional study. PURPOSE The purpose of this study was to evaluate a novel landmark for the cervical pedicle screw insertion point. OVERVIEW OF LITERATURE To improve the accuracy of pedicle screw placement, several studies have employed the lateral mass, lateral vertical notch, and/or inferior articular process as landmarks; however, we often encounter patients in whom we...
