Orthopedic implants should have sufficient strength and promote bone tissue regeneration. However, most conventional are optimized for use either under high mechanical load or active osseointegration. To achieve the dual target of durability biocompatibility, polyether ether ketone (PEEK) filaments reinforced with internal titanium dioxide (TiO2) nanoparticles via dopamine-induced polymerizatio...

Electrically conductive polymers reinforced with carbon nanotubes (CNTs) have generated a great deal of scientific and industrial interest in the last few years. Advanced thermoplastic composites made of three different weight percentages (8%, 9%, and 10%) of multiwalled CNTs and polyether ether ketone (PEEK) were prepared by shear mixing process. The temperature- and pressure-dependent electri...

Objective Surgical treatments for early onset scoliosis (EOS) typically require multiple operations and many complications. A more flexible growing rod construct might result in a more flexible spine with fewer complications. Polymer rods (polyetheretherketone, PEEK) are relatively flexible in bending, and so might allow for greater range of motion (ROM) during treatment. The purpose of this st...

INTRODUCTION Concerns regarding UHMWPE wear particle induced osteolysis [1] have led to investigations of alternative bearing materials. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) has been shown in animal studies to have a similar biological activity to UHMWPE [2], whilst hip and knee configurations incorporating this polymer display reduced wear rates when compared with convent...

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 ...

Poly-ether-ether-ketone (PEEK) fabricated by fused deposition modeling for medical applications was evaluated in terms of mechanical strength and in vitro cytotoxicity in this study. Orthogonal experiments were firstly designed to investigate the significant factors on tensile strength. Nozzle temperature, platform temperature, and the filament diameter were tightly controlled for improved mech...

Total hip replacement has been a successful surgical intervention for many years. However, concerns regarding UHMWPE wear particle induced osteolysis [1], have led to alternative bearing materials to be sought. Carbon-fibre reinforced poly-ether-ether-ketone (CFR-PEEK) is a fibre-reinforced polymer which has shown reduced wear in hip and knee configurations compared with conventional polyethyle...

A novel co-curing process was proposed for the bonding of carbon fibre/epoxy composites by replacing traditional epoxy adhesives with fibre/PEEK (CF/PEEK) tapes, an attempt to improve structure integrity. The lap-shear strengths, fatigue resistance and mode-I mode-II fracture behaviour co-cured joints at 22 °C 130 were investigated, failure mechanisms also studied. experimental results demonstr...
