BACKGROUND Anterior cervical diskectomy and fusion (ACDF) is a well-established surgical treatment for radiculopathy and myelopathy. Previous studies showed that empty PEEK cages have lower radiographic fusion rates, but the clinical relevance remains unclear. This paper's aim is to provide high-quality evidence on the outcomes of ACDF with empty PEEK cages and on the relevance of radiographic ...

BACKGROUND Large cranial defects represent reconstructive challenges. Polyetheretherketone (PEEK) implants are preoperatively tailored to the exact size of the defect and exhibit an excellent combination of strength, durability, and environmental resistance. This study presents our experience with patient-specific PEEK implants with computer modeling. METHODS A retrospective chart review was ...

Medical implant devices have evolved in the past decade and now many surgical specialties have turned to polyetheretherketone (PEEK) devices for its ideal properties. In Neurosurgery, PEEK has its role in many operations such as cervical cages after anterior cervical discectomy and as a prosthetic implant for cranioplasty where autologous cranioplasty is not possible. We discuss our case of a p...

Polyetheretherketone (PEEK) is a semi-crystalline linear polycyclic thermoplastic that has been proposed as a substitute for metals in biomaterials. PEEK can also be applied to dental implant materials as a superstructure, implant abutment, or implant body. This article summarizes the current research on PEEK applications in dental implants, especially for the improvement of PEEK surface and bo...

Polyetheretherketone (PEEK) is a kind of synthetic thermoplastic polymer, because of its good biological compatibility, chemical stability and radiolucency, it has been widely used in the field of medicine. Compared with the titanium, the elastic modulus of PEEK is closer to human cortical bone, PEEK could be a viable alternative material for dental implants. Nevertheless the inherent bio-inert...

Recently, a new class of spinal devices called interspinous spacers (ISPs) has been introduced. A number of designs have been developed, which vary from non-compressible metallic spacers to compressible cushion-like devices. Following the path of other spinal devices, they are composed of materials ranging from allograft bone, titanium alloy, polyetheretherketone (PEEK), and elastomeric prepara...

The author retrospectively studied twenty-two patients who underwent revision lumbar surgeries using ALLIF with a self-anchored stand-alone polyetheretherketone (PEEK) cage. The operation time, blood loss, and perioperative complications were evaluated. Oswestry disability index (ODI) scores and visual analog scale (VAS) scores of leg and back pain were analyzed preoperatively and at each time ...
