    Abstract: Absorbable microspheres comprising a copolymer formed from greater than 80 to about 99 mole percent D,L-lactideg, L(−)-lactide, D(+)-lactide, or meso-lactide and combinations thereof, and about 1 to less than 20 mole percent of a different second monomer selected from the group consisting of p-dioxanone and trimethylene carbonate and combinations thereof, said microspheres having a particle size ranging from about 5 to 2000 microns. Also described herein are formulations comprising such absorbable microspheres.
