Evaluation of a Novel PEEK Titanium Composite (PTC) Interbody Cage in an Ovine Lumbar Interbody Fusion

چکیده
INTRODUCTION: The majority of interbody devices for spine fusion are PEEK. Other interbody devices use a rough 2D titanium surface or full porous titanium or tantalum cores, which have been shown in-vitro and in-vivo to promote osteoinduction and osteointegration, respectively. Combining the increased osteogenic environment that titanium provides and the minimized subsidence and radiolucency from PEEK, a unique interbody device has been developed. This PEEK Titanium Composite (PTC) implant consists of two 3-dimensional porous titanium alloy Ti6Al4V endplates with a PEEK core. This study examines the PTC implant and its efficacy to cause intervertebral body fusion in an ovine lumbar spinal fusion model relative to a similar PEEK implant.

First Results of a New Vacuum Plasma Sprayed (VPS) Titanium-Coated Carbon/PEEK Composite Cage for Lumbar Interbody Fusion
The aim of this study was to assess the performance of a new vacuum plasma sprayed (VPS) titanium-coated carbon/polyetheretherketone (PEEK) cage under first use clinical conditions. Forty-two patients who underwent a one or two segment transforaminal lumbar interbody fusion (TLIF) procedure with a new Ca/PEEK composite cage between 2012 and 2016 were retrospectively identified by an electronic ...
متن کاملTitanium coated cage enhances fusion rates in posterior lumbar interbody fusion
Titanium coated PEEK cages incorporate the advantages of both PEEK, which offers a native-like elastic modulus and a radiolucent behaviour, and Titanium which provides improved biocompatibility and promotes osseointegration. In this study, we evaluated the response of Titanium plasma sprayed PEEK cages to provide safe support of the lumbar spine and promote bony fusion.
متن کاملTransforaminal lumbar interbody fusion rates in patients using a novel titanium implant and demineralized cancellous allograft bone sponge
BACKGROUND Transforaminal lumbar interbody fusion (TLIF) with grafting and implant options like iliac crest bone graft (ICBG), recombinant bone morphogenetic protein (rhBMP), and polyetheretherketone (PEEK) cages have been reported to achieve extremely high fusion rates. Unfortunately, these options have also been frequently cited in the literature as causing postoperative morbidity and complic...
متن کاملComparison of outcomes and safety of using hydroxyapatite granules as a substitute for autograft in cervical cages for anterior cervical discectomy and interbody fusion
Background: After cervical discectomy, autogenetic bone is packed into the cage to increase the rate of union between adjacent vertebral bodies, but donor site–related complications can still occur. In this study we evaluate the use of hydroxyapatite granules as a substitute for autograft for interbody fusion. Methods: From November 2008 to November 2011, 236 patients participated in ...

Object. The implantation of interbody fusion cages allows for the restoration of disc height and the enlargement of the neuroforaminal space. The purpose of this study was to compare the extent of subsidence occurring after conventional cage placement compared to a novel wider cage placement technique. Methods. This study is a retrospective evaluation of radiographs of patients who underwent st...
