Introduction: In open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. This study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    Materi...

PURPOSE Pedicle screw fixation in the upper cervical spine is a difficult and high-risk procedure. The screw is difficult to place rapidly and accurately, and can lead to serious injury of spinal cord or vertebral artery. The aim of this study was to design an individualized 3D printing navigation template for pedicle screw fixation in the upper cervical spine. METHODS Using CT thin slices da...

Nothing lasts forever. Any humanmade material, used in anything from toys to bridges, will eventually fail, if not maintained and repaired. Traditionally, this problem has been addressed through extensive inspection and expensive replacement of damaged parts. Biological systems, however, have evolved to include alternative ways to repair internal and external damage via healing mechanisms. Mate...

Background: This study was conducted to evaluate the clinical outcomes of acromioclavicular joint (ACJ) fixation with hook plate (HP) and continuous loop double endobutton fixation (CLDE) in treatment of the acute acromioclavicular joint (ACJ) dislocation. Methods: In this retrospective study, 8 patients with HP and 9 patients with CLDE fixations were compared for acute ACJ dislocations. ...

Various methods for anterior pelvic ring fixation have been described in the literature, each with specific advantages and disadvantages. We describe a modified minimally invasive subcutaneous technique fixation: Bridging Infix. It combines benefits of internal plate external fixator principles. merged features existing INFIX Pelvic Bridge techniques during design. Similar to these techniques, ...

Recent research suggests that new objects appearing in real-world scenes are prioritized for eye fixations and by inference, for attentional processing. We examined whether semantic consistency modulates the degree to which new objects appearing in a scene are prioritized for viewing. New objects were added to photographs of real-world scenes during a fixation (new object with transient onset) ...

BACKGROUND Press-fit fixation of patellar tendon-bone anterior cruciate ligament autografts is an interesting technique because no hardware is necessary. For hamstring tendon grafts, no biomechanical data exist of a press-fit procedure. HYPOTHESIS Press-fit femoral fixation of hamstring tendons is mechanically equivalent to press-fit patellar tendon-bone fixation. STUDY DESIGN Controlled la...

OBJECTIVES To establish a laboratory model of implant cutout, which can evaluate the effect of implant design on cutout resistance in a clinically realistic "worst case" scenario. SETTING Orthopaedic biomechanics laboratory. DESIGN Implant cutout was simulated in an unstable pertrochanteric fracture model, which accounted for dynamic loading, osteoporotic bone, and a defined implant offset....

STUDY DESIGN A retrospective case series of patients with myelomeningocele (MMC) who underwent kyphectomy and posterior segmental fixation using Luque rods and 16-gauge wires. OBJECTIVE To assess outcomes after posterior kyphectomy and segmental fixation for kyphosis in patients with MMC. METHODS Thirteen consecutive patients who underwent posterior kyphectomy for transforaminal fixation co...
