A total of 25 consecutive patients suffering from degenerative cervical disc disease who underwent three-level anterior cervical discectomy and fusion (ACDF) including polyetheretherketone (PEEK) cages packed with allograft were followed up for at least two years. The fusion rate reached 72% (18/25), and asymptomatic pseudarthrosis was seen in 6 patients but without mobility on flexion-extensio...

Total joint replacement is a successful surgical intervention for the treatment of the degeneration of many joints, particularly the hip and knee. As the demand for joint replacement grows, and the life expectancy of the population increases, the performance requirements of these implants also changes. New materials, to improve longevity and enhance performance have been explored including PEEK...

Interbody cages are commonly used to augment interbody fusion. Commonly materials include titanium (Ti) and polyetheretherketone (PEEK), with their inherent differences. The aim of this study is perform a systematic review meta-analysis compare between the various clinical radiological outcomes Ti PEEK spinal cages. A comparing in patients undergoing fusion was performed. PubMed, Scopus, Web Sc...

Poly aryl-ether-ether-ketone (PEEK) is an alternative to metal alloys in orthopedic applications. Although the polymer provides many significant advantages such as excellent mechanical properties and non-toxicity, it suffers from insufficient elasticity and biocompatibility. Since the elastic modulus of diamond-like carbon (DLC) is closer to that of cortical bone than PEEK, the DLC/PEEK combina...

Polyetheretherketone (PEEK) generally exhibits physical and chemical characteristics that prevent osseointegration. To activate the PEEK surface, we applied oxygen and ammonia plasma treatments. These treatments resulted in surface modifications, leading to changes in nanostructure, contact angle, electrochemical properties and protein adhesion in a plasma power and process gas dependent way. T...

BACKGROUND The purposes of the present study are to evaluate the subsidence and nonunion that occurred after anterior cervical discectomy and fusion using a stand-alone intervertebral cage and to analyze the risk factors for the complications. METHODS Thirty-eight patients (47 segments) who underwent anterior cervical fusion using a stand-alone polyetheretherketone (PEEK) cage and an autologo...

BACKGROUND Surgical intervention is increasingly performed as the primary treatment of unstable Hangman's fracture. Some authors have advocated using anterior C2/3 discectomy with interbody fusion and plating to treat unstable Hangman's fracture combined with intervertebral disc injury; however, there are few reports on unstable Hangman's fracture treated by anterior interbody fusion with the c...

BACKGROUND Calcium sulphate (CS) has been used in bone grafting since the 1800s. It has not replaced autograft as the gold standard, however, since its dissolution occurs rapidly in bodily fluids, meaning that the material cannot support long-term bone growth. Here, the polymer poly (ether ether ketone) (PEEK) was used to slow dissolution in in vitro physiological environments and augment the m...

Background The use of intervertebral cages within the interbody fusion setting is ubiquitous. Synthetic are predominantly manufactured using materials such as Ti and PEEK. With advent additive manufacturing techniques, it now possible to spatially vary complex 3D geometric features devices, enabling devices match stiffness native tissue better promote bony integration. To date, impact surface p...
