Abstract

Porous poly(lactic-glycolic) acid (PLG) implants were fabricated using a modified salt-leaching technique. The in vitro degradation characteristics of these implants were then examined over 8 week period. The increase in dimensions of the implants between weeks 3 and 4 was due to polymer swelling. With time, this increase was overtaken by a loss in dimensions due to mass loss, which increased significantly after week 4. The implants exhibited a high level of degradation by week 8. The fabrication technique yielded highly porous implants with significant permeability. These characteristics make such implants ideal candidates for use as scaffolds for repair or regeneration of tissues.
