Objective: The goal of this study was to evaluate the comparative accuracy and safety of navigation-based approaches for cervical pedicle screw (CPS) placement over fluoroscopic techniques.
Methods: A systematic search of the literature published between January 2006 and December 2019 relating to CPS instrumentation and the comparative accuracy and safety of fluoroscopic and intraoperative computer-based navigation techniques was conducted. Several databases, including the Cochrane Library, PubMed, and EMBASE, were systematically searched to identify potentially eligible studies.
Objective: The goal of this study was to review the incidence of complications and unplanned re-operations after surgery for metastatic spinal tumors.
Background: The spinal column is the most common osseous site for metastatic spread. The goals of the treatment of spinal metastases are largely palliative.
Aim: To find thresholds at which laypersons and dental professionals perceive abnormalities in two facial frontal esthetics variables: facial symmetry and vertical harmony.
Materials And Methods: A baseline frontal image of a young male face with optimum facial proportions was generated from a real image using a photo editing software. Different facial asymmetry images were then generated from this image by manipulating the chin point position at 2 mm increment to the left side.
Aim: To find thresholds at which laypersons and dental professionals from Jordanian population perceive abnormalities in sagittal positioning of upper and lower jaws as a major determinant to facial profile esthetics.
Materials And Methods: Using photo editing software, a baseline profile image of a young male was manipulated on a 2 mm incremental basis to move each of the upper and lower jaws backward and forward relative to true vertical line (TVL) at which four variables of maxillary and mandibular retrusion and protrusion were researched. A total of 120 participants divided equally into four groups of laypersons, general dental practitioners (GDPs), orthodontists, and oral and maxillofacial surgeons (OMFSs) rated the images using an analog scale of 100 mm long.
Introduction: Surgical approaches to pathologies of the L5 vertebra constitute a significant challenge. Our aim was to review the efficacy and safety of the surgical approaches to L5 corpectomy and reconstruction across the range of presenting pathology.
Materials And Methods: This systematic review was conducted according to PRISMA guidelines, and databases were searched from 1970 to January 2020.
Study Design: A systematic review and meta-analysis.
Objective: The purpose of this study was to evaluate the clinical outcome and safety of sacroplasty for patients with secondary metastatic lesions to the sacrum.
Methods: Several databases, including the Cochrane library, PubMed and EMBASE, were systematically searched to identify potentially eligible articles in English language.
Study Design: Systematic review and meta-analysis of randomized controlled trials (RCTs).
Objective: This systematic review and meta-analysis was performed with the aim of exploring the differences in pedicle screw positioning accuracy, surgical time, length of hospital stay, postoperative back and leg Visual Analog Scale, revision surgeries, and intraoperative radiation time and exposure between robot-assisted technology and conventional freehand technique based on RCTs.
Methods: Several databases, including the Cochrane library, PubMed, and EMBASE were systematically searched to identify potentially eligible articles.
Introduction: MRI is the established gold standard for imaging acute spinal cord injury (SCI). Our aim was to identify the prognostic value, in terms of neurological outcome, of extradural and intradural features detected on MRI performed acutely following traumatic cervical SCI.
Materials And Methods: Several databases were systematically searched to identify potentially eligible articles until December 2019.
Study Design: Systematic review and meta-analysis.
Background: Three-column osteotomies (3-CO) have gained popularity in the last decade as part of the armamentarium for the surgical correction of sagittal imbalance in patients with adult spinal deformity (ASD). Three-column osteotomies in the form of pedicle subtraction osteotomy (PSO) may be necessary to achieve adequate correction for severe and rigid spinal deformity.
Objective: To find an optimal force that can be loaded onto an orthodontic microimplant to fulfill the biomechanical demands of orthodontic treatment without diminishing the stability of the microimplant.
Materials And Methods: Using the finite element analysis method, 3-D computer-aided design models of a microimplant and four cylindrical bone pieces (incorporating cortical bone thicknesses of 0.5, 1.
Minimization schema in nature affects the material arrangements of most objects, independent of scale. The field of cellular solids has focused on the generalization of these natural architectures (bone, wood, coral, cork, honeycombs) for material improvement and elucidation into natural growth mechanisms. We applied this approach for the comparison of a set of complex three-dimensional (3D) architectures containing the same material volume but dissimilar architectural arrangements.
