Biomechanical testing of a unique built-in expandable anterior spinal internal fixation system
BACKGROUND Expandable screws have greater pullout strength than conventional screws. The purpose of this study was to compare the biomechanical stability provided by a new built-in expandable anterior spinal fixation system with that of 2 commonly used anterior fixation systems, the Z-Plate and the Kaneda, in a porcine partial vertebral corpectomy model. METHODS Eighteen porcine thoracolumbar...
متن کاملTriangulation of Anterior Vertebral Double-screw Fixation- a Biomechanical Study
Introduction: Anterior spinal instrumentation of the thoracic and lumbar spine has gained in popularity since Dwyer et al [1] developed the cable system in 1964. However, implant loosening, screw breakage and cut-throughs have been noted clinically when using Dwyer or Zielke's Ventrale Derotations Spondylodese (VDS) instrumentations [2,3]. To avoid these complications and pseudarthrosis, one ma...
متن کاملBiomechanical study of a novel self-locking plate system for anterior cervical fixation
BACKGROUND Anterior cervical plate had developed continuously, and this study aimed to assess the biomechanics of a novel self-locking plate system for anterior cervical fixation designed by ourselves. METHODS Twelve anterior cervical plates (i.e., six novel plates and six DePuy plates) were subjected to a pull-out test and a fatigue test. In addition, 12 C1-T1 cervical spine specimens underw...
متن کاملMechanical testing of a device for subcutaneous internal anterior pelvic ring fixation versus external pelvic ring fixation
BACKGROUND Although useful in the emergency treatment of pelvic ring injuries, external fixation is associated with pin tract infections, the patient's limited mobility and a restricted surgical accessibility to the lower abdomen. In this study, the mechanical stability of a subcutaneous internal anterior fixation (SIAF) system is investigated. METHODS A standard external fixation and a SIAF ...
متن کاملBiomechanical evaluation of metacarpal fracture fixation: application of a 90° internal fixation model.
PURPOSE Complications in metacarpal fracture treatment increase in proportion to the severity of the initial injury and the invasiveness of the surgical fixation technique. This manuscript evaluates the feasibility of minimizing internal fixation construct size and soft tissue dissection, while preserving the advantages of stable internal fixation in a biomechanical model. We hypothesized that ...
