title: Mechanical properties of some fibre reinforced polymer composites after implantation as fracture fixation plates.
abstract: Continuous fibre reinforced composite bone plates made from graphite/polysulphone and glass/epoxy laminates were implanted for 16 weeks on osteotomized canine femurs and for 12 months on intact femurs. After sacrifice, the plates were removed and tested in four point bending for stiffness and strength. There were no significant differences in properties between control and implanted plates in the 16 week study. Both the glass/epoxy and the graphite/polysulphone systems showed deterioration after implantation for 12 months.
