Effect of Pedicle Fill on Axial Pullout Strength in Spinal Fixation After Rod Reduction.
Rod reduction to pedicle screws is used for a variety of spinal fixation procedures; however, it can alter the integrity of the screw-bone interface. The authors investigated the effect of pedicle fill (ratio of pedicle screw diameter to pedicle diameter) on the strength of the screw-bone interface after simulated rod reduction on 17 vertebrae (3 thoracolumbar spine specimens). Pedicle diameter...
متن کاملRotary ultrasonic bone drilling: Improved pullout strength and reduced damage.
Bone drilling is one of the most common operations used to repair fractured parts of bones. During a bone drilling process, microcracks are generated on the inner surface of the drilled holes that can detrimentally affect osteosynthesis and healing. This study focuses on the investigation of microcracks and pullout strength of cortical-bone screws in drilled holes. It compares conventional surg...
متن کاملEffect of Different Distal Fixation Augmentation Methods on the Pullout Strength of Fassier-Duval Telescoping Rods.
Antegrade telescoping rods have been introduced for use in pediatric patients with osteogenesis imperfecta (OI) to decrease the incidence of long-bone fractures and to correct and prevent deformities. Recent studies have documented failures of telescoping intramedullary rods due to inadequate distal fixation. The purpose of this study was to evaluate the pullout strength of distal fixation of t...
متن کاملPullout strength of knotless suture anchors.
PURPOSE Suture anchors are used consistently for repairs of soft tissues, especially around the glenohumeral joint. These anchors can be used either arthroscopically or in an open procedure to anatomically restore the labrum and capsular tissues to the glenoid after avulsion injuries (Bankart lesion). The purpose of this study was to analyze the pullout strength of a new knotless suture anchor ...
متن کاملComparison and prediction of pullout strength of conical and cylindrical pedicle screws within synthetic bone
BACKGROUND This study was designed to derive the theoretical formulae to predict the pullout strength of pedicle screws with an inconstant outer and/or inner diameter distribution (conical screws). For the transpedicular fixation, one of the failure modes is the screw loosening from the vertebral bone. Hence, various kinds of pedicle screws have been evaluated to measure the pullout strength us...
