摘要 |
The invention relates to bioactive, biocompatible, bioabsorbable surgical composites and devices, such as pins, screws, plates, tacks, bolts intramedullary nails, suture anchors, staples or other devices which are applied in bone-to-bone, soft tissue-to-bone or soft tissue-to-soft tissue fixation or in fixation of bioabsorbable and/or biostable implants in, and/o r on, bone or soft-tissue, which composites and devices are fabricated of bioabsorbable polymers, copolymers or polymer alloys that are self-reinforce d and contain ceramic particles or reinforcement fibres and porosity. Typical example is crushed particles of bioactive glass spheridized by flame sprayin g used to form a composite with poly (L/DL) lactide which is then extruded and then reinforced by uniaxial die-drawing.
