  • Title: Intramedullary fixation of cortical bone osteotomies with self-reinforced polylactic rods in rabbits.
    Author: Majola A, Vainionpää S, Vihtonen K, Vasenius J, Törmälä P, Rokkanen P.
    Journal: Int Orthop; 1992; 16(1):101-8. PubMed ID: 1572762.
    Abstract:
    Osteotomies of the femoral shaft in rabbits were fixed with intramedullary rods made of poly-L-lactic acid (SR-PLLA) and poly-DL/L-lactic acid (SR-PDLLA/PLLA). Follow up was from one week to 2 years. In the PLLA group, in 37 out of 40 osteotomies the fixation was firm and the bone was united. In the PDLLA/PLLA group, the fixation was firm in 30 out of 45, but in 13 of these angular deformity of more than 10 degrees had occurred. The fixation had failed in 15. No inflammatory or foreign body reaction was seen in either group. This study demonstrates that SR-PLLA rods are suitable fixation for cortical osteotomies in rabbits.
