Abstract
Biodegradable oligomeric polyesters based upon hydroxy acids, such as glycolic acid (GA), lactic acid (LLA), and copolymers thereof are described. Composites that include biodegradable polyesters and bioabsorbable fillers are also described. The described polymers and composites are injectable and in situ curable.
