Evidence-based support for S1 transpedicular screw entry point modification
BACKGROUND In the literature, 'below and lateral to the superior S1 facet' is defined as the basic technique for screw introduction. Until a recently published modification, no analysis for alternative starting point has been proposed nor evaluated, although some surgeons claim to use some modifications. In this study, we analyse the data from anatomical and radiological studies for optimal sta...
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 کاملCadaveric 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 کاملPercutaneous Transpedicular Screw Insertion Technique ( Sextant )
Boucher was the first to use screws that crossed through the strongest point of attachment of the facet joint into the pedicle and the body of the vertebra below. He declared a pseudorthrosis rate of 14% to 17% including multilevel fusions (1). The use of pedicle screw–assisted spinal stabilization has become increasingly popular worldwide. Pedicle screw systems engage all three columns of the ...
متن کاملArchives of Neuroscience Transpedicular Screw Insertion Guidance Device (TSIGD), A New Device for Spinal Transpedicular Screw Placement (A Pilot Study)
Background: Trans-pedicular screw placements have been an increasingly popular procedure in many neurosurgery and orthopedic departments. Any mistake at performing the technique could be followed by irreversible neurological deficit and damage of Para spinal vital structures as well as less stability for future fusion. Objectives: In this study we tried to show the benefits and capabilities of ...
