Background: The modern paradigm for managing cervical disc diseases uses both ventral and dorsal approaches, with procedures being more common. consist primarily of discectomy, followed by fusion. symptoms syndromes can be mimicked a number other neurological disorders. Objective: To evaluate the efficacy polyetheretherketone (PEEK) cage only in four levels anterior discectomy as one surgical o...

This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...

BACKGROUND Surgical treatments for early onset scoliosis (EOS), including growing rod constructs, involve many complications. Some are due to biomechanical factors. A construct that is more flexible than current instrumentation systems may reduce complications. The purpose of this preliminary study was to determine spine range of motion (ROM) after implantation of simulated growing rod construc...

Carbon-fiber-reinforced polyetheretherketone (CFR-PEEK) has been successfully used in orthopedic implants. The aim of this systematic review is to investigate the properties, technical data, and safety of CFR-PEEK biomaterial and to evaluate its potential for new innovation in the design of articulating medical devices. A comprehensive search in PubMed and EMBASE was conducted to identify artic...

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.

OBJECTIVE To study clinical and radiographic outcome of patients who underwent the Cervios cage-assisted anterior cervical discectomy and fusion (ACDF) without plate fixation in single to two-level degenerative disc disease (DDD). MATERIAL AND METHOD Sixty-seven patients suffering from cervical DDD with various symptoms such as radiculopathy, myelopathy, or both were retrospectively evaluated...
