Abstract
Described herein are biocompatible compositions that contain a copolymer and a filler material. In particular, described herein are compositions that include a copolymer and a filler which may be a calcium salt. Also described herein are methods in which the compositions are used to attach soft tissue to bone.
Claims19
A bioabsorbable polymer composition consisting of:
- (a) from 65 to 70 percent by weight of a copolymer, based on the weight of said bioabsorbable polymer composition, wherein said copolymer is selected from the group consisting of poly l-lactide:co-glycolide, poly l-lactide:d,l-lactide, and mixtures thereof;
- and
- (b) from 30 to 35 percent by weight of a ceramic filler, based on the weight of the bioabsorbable polymer composition, wherein said ceramic filler consists of calcium sulphate and optionally tricalcium phosphate.
