Advances have been achieved in the design and biomechanical performance of orthopedic implants in the last decades. These include anatomically shaped and angle-stable implants for fracture fixation or improved biomaterials (e.g. ultra-high-molecular-weight polyethylene) in total joint arthroplasty. Future modifications need to address the biological(More)
Implant related infection is one of the most feared and devastating complication associated with the use of orthopaedic implant devices. Development of anti-infective surfaces is the main strategy to prevent implant contamination, biofilm formation and implant related osteomyelitis. A second concern in orthopaedics is insufficient osseointegration of(More)
BACKGROUND The effects of freezing-thawing cycles on intramedullary bone-implant interfaces have been studied in a rat model in mechanical pull-out tests. IMPLANTS: Twenty TiAl6V4 rods (Ø 0.8 mm, length 10 mm) implanted in rat tibiae METHODS 10 rats underwent bilateral tibial implantation of titanium rods. At eight weeks, the animals were sacrificed and(More)
High performance multiprocessors generally require a very complex underlying hardware. This applies notably to shared memory systems, where the communication grain is fine and hence low latencies are critical. We describe the prototype of a multiprocessor network which is based on low-cost standard technology. We point out the main difficulties encountered(More)
Many different technologies have been used to enhance osseointegration in orthopaedic and dental implant surgery. Hydroxyapatite coatings, pure or in combination with growth factors or bisphosphonates, showed improved osseointegration of titanium alloy implants. We choose a different approach to enhance osseointegration: plasma chemical oxidation was used(More)
