In this study, the poly-D,L-lactic (PDLLA) absorbable rods were comfirmed to have good biocompatibility by embed experiment, and the degradation experiment in vitro and in vivo showed good mechanical features and total in vivo absorption of the rods, indicating that the rods meet the demands to be a biodegradable internal fixation material.
