Biomechanical evaluation of a novel cervical spine posterior fixation technique using C1 arch screws: An in-vitro cadaveric stu
INTRODUCTION: The complex anatomy and biomechanics of the atlanto-axial motion segment impose technical challenges in the achievement of safe and successful surgical stabilization and fusion. The coauthors have recently reported successful clinical results using a novel C1-C2 stabilization technique employing C1 multi-axial posterior arch screws (MA-PAS) in a series of 3 patients (see Fig.1a-c)...
متن کاملBiomechanical Comparison of Different Stabilization Constructs for Unstable Posterior Wall Fractures of Acetabulum. A Cadaveric Study
PURPOSE Operative treatment of unstable posterior wall fractures of acetabulum has been widely recommended. This laboratory study was undertaken to evaluate static fixation strength of three common fixation constructs: interfragmentary screws alone, in combination with conventional reconstruction plate, or locking reconstruction plate. METHODS Six formalin-preserved cadaveric pelvises were us...
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 کاملA cadaveric study of bilateral configuration of posterior bifurcation of posterior communicating artery in Indian population.
INTRODUCTION Various studies have been done regarding variations of circle of Willis, but few literatures are available about the detail configurations on Indian population. Posterior communicating artery is the main collateral channel between the vertebrobasilar and carotid system. It may act as a main source of blood flow via posterior cerebral artery if fetal configuration is present. Aim of...
متن کاملBiomechanical comparison of bicortical versus unicortical screw placement of proximal tibia locking plates: a cadaveric model.
OBJECTIVE The purpose of this study was to compare the biomechanical properties of bicortical with unicortical screws in a proximal tibial fracture cadaveric model. SETTING Biomechanics laboratory at a Level 1 trauma center. PATIENTS/PARTICIPANTS Eight pairs (4 male and 4 female) of elderly (average age, 79 years; range, 63 to 104 years) cadaveric tibiae. INTERVENTION Osteotomies were per...
