pedicle screw fixation system

pedicle screw fixation system

Orthopedic surgery A multicomponent device constructed from stainless or titanium-based steel, consisting of solid, grooved, or slotted plates of rods that are longitudinally interconnected and anchored to adjacent vertebrae using bolts, hooks, or screws Indications Stabilize and fuse the spine in degenerative spondylolisthesis, fusion after spinal fusion, lumbar fractures, and in surgically repaired spinal pseudoarthroses. See Omni litigation.

The company said the Swedge Pedicle Screw Fixation System is intended to provide immobilization and stabilization of spinal segments in skeletally-mature patients as an adjunct to fusion in the treatment of acute and chronic instabilities or deformities of thoracic, lumbar, and sacral spine: degenerative spondylolisthesis, fracture, dislocation, deformities or curvatures, spinal tumor, pseudoarthrosis as well as failed previous fusion.
Nevertheless, the development of interspinous fusion devices (IFD) is intended to be an alternative to pedicle screw fixation system and to aid in the stabilization of the spine with interbody fusion.
Georgetown, TX, May 15, 2014 --(PR.com)-- On November 5th 2013, the United Sates Patent and Trademark Office issued a Utility patent for Eminent Spine's Pedicle Screw Fixation System (DiamondBack Pedicle Screw).
Public Citizen focused on AcroMed Corp., one of the better known manufacturers whose founder and majority stockholder is Arthur Steffee, inventor of a pedicle screw fixation system. Public Citizen reported that each member of AcroMed's medical advisory panel was given a stock option agreement in exchange for serving as a member.
The PLF is presented as a gold standard method in spondylolisthesis by some authors because pedicle screw fixation systems have advantages such as theoretically the reduction of spondylolisthesis and the correction of deformity and also have been reported to increase fusion rates of rigid fixation (7,14-16).
With the advent of reliable percutaneous pedicle screw fixation systems, some surgeons recently tried to use this method in the treatment of thoracic fractures to minimize the invasiveness of an entirely open approach [4, 5].
