Research Abstract

This study evaluated clinical functions of bioabsorbable materials and high-strength poly (vinyl alcohol) fiber.
"Bioabsorbable fixation device for artificial ligament and bone fixation" was made from composite Poly L Lactide (PLLA) and Poly Caprolactone (PCL) threads. Durability and rigidity of the fixation was evaluated using clinic-simulated impactfatigue testing.The device showed excellent fatigue resistant and relatively good regidity of fixation.
"Anti-adhesive membrane was made from crosslinked gelatin and evaluated using flexor tendon of chicken finger. Although the aniti-adhesive function was excellent, handling characteristics of the material is not sufficient to use in clinic. We are now evaluating Poly (LA-CL) co-polymer for this application.
"polymer surface for bone bonding" was obtained by surface graft polymerization of a phosphate-containing monomer. Histologic and mechanical evaluation showed that this surface promotes bonding to bone, encouraging application as a pliable orthopaedic implant which needs high toughness and bone bonding.
"Biodegradation of high-strength poly (vinyl alcohol) fiber" was evaluated to develop a new suture with high strength and good handling characteristics. Mono-filament, multi-filament bundle, braided thread, and braided thread with one knot were prepared from higt-strength PVA fibers obtained by a gel-spinning technique. Although, no appreciable weight change of the PVA fibers was observed, significantly more marked deterioration of the PVA fibers in vivo than in vitro was observed. This was explainedin terms of oxidation by active oxygens generated in the body. The braided thread with one knot showed the highest reproducibility in measuring the strength change in vivo.
Applicability of those materials was discussed based in these results.
