摘要：

Semi-crystalline poly-L-lactic acid (PLLA) wire was implanted intramedullary in rat tibiae to evaluate the fracture healing processes and the tissue reaction or: the PLLA in a fractured bone. The fracture healing after PLLA implantation was compared to a sham-operated group of animals. In all animals with intramedullary PLLA wire implantation newly formed bone was seen immediately against the implant 2 and 6 months after implantation. None of the sham-operated animals showed newly formed intramedullary bone formation other than fracture heating callus and normal trabecular bone.
