Abstract

Poly(desaminotyrosyl-tyrosine ethyl ester carbonate), or PDTEc, is a candidate bioresorbable polymer for use in small bone fracture fixation and is shown to generate a good hard tissue response in vivo. The general effect of the in vivo environment on bone pin prototypes made of either 44.2-kDa or 71.8-kDa weight-average molecular weight (Mw) PDTEc is determined through mechanical testing and gel permeation chromatography (GPC) analysis of retrieved specimens. Results indicate that the lower-molecular-weight material is useful in biodistribution studies of PDTEc degradation products. The higher-molecular-weight material is useful in further orthopedic device prototype development.
