Assessment of a percutaneous iliosacral screw insertion simulator
BACKGROUND Navigational simulator use for specialized training purposes is rather uncommon in orthopaedic and trauma surgery. However, it reveals providing a valuable tool to train orthopaedic surgeons and help them to plan complex surgical procedures. PURPOSE This work's objective was to assess educational efficiency of a path simulator under fluoroscopic guidance applied to sacroiliac joint...
متن کاملA Finite Element Study of Electrode Location during Stimulus Evoked Electromyographic Monitoring of Iliosacral Screw Insertion
INTRODUCTION: Pelvic ring fractures are a relatively common form of orthopaedic trauma. While mechanical stability may be restored by the insertion of iliosacral screws, the proximity of the ideal screw trajectory to the fifth lumbar and first sacral nerve roots (S1), as well as the spinal canal make nervous tissue injury a potential hazard. Fluoroscopy has typically been used to ensure proper ...
متن کاملMeasurement of Optimal Insertion Angle for Iliosacral Screw Fixation Using Three-Dimensional Computed Tomography Scans
BACKGROUND Percutaneous iliosacral screw fixation can provide stable fixation with a minimally invasive surgical technique for unstable posterior pelvic ring injuries. This surgical technique is not limited by cases of difficult fracture patterns, sacral dysplasia, and small sacral pedicles that can occur in Asians. The purpose of this study was to investigate the incidence of the sacral dyspla...
متن کاملA Finite Element Model of Electrode Placement During Stimulus Evoked Electromyographic Monitoring of Iliosacral Screw Insertion
Pelvic ring fractures that occur as a result of substantial orthopedic trauma are frequently repaired using iliosacral screws to stabilize the fracture. Stimulus evoked electromyography, using pulsed current stimuli provided through the drill bit cathode, has been advocated to prevent nerve root injury during iliosacral screw insertion. Our objective was to examine the effects of anode location...
متن کاملComputer Assisted Surgery for Iliosacral Screw Placement-How Far have we gone?
Unstable pelvic ring injuries require definite operative fixation. While the posterior ring can be fixed utilizing open approaches, percutaneous screw fixation has become the treatment of choice avoiding the complications of open approaches. As the pelvis is a complex three-dimensional (3D) shape with many neurovascular structures situated within it, a thorough knowledge and understanding of th...
