The title of the report “In vivo effects of intra-articular injection of gelatin hydrogen microspheres containing basic fibroblast growth factor on experimentally induced defects in third metacarpal bones of horses” (Am J Vet Res 2008;69:1555–1559) is incorrect. The correct title is “In vivo effects of intra-articular injection of gelatin hydrogel microspheres containing basic fibroblast growth factor on experimentally induced defects in third metacarpal bones of horses.”
