AbstractAllografts are produced from natural sources and have been used in orthopedic repair procedures for a long time in humans and animals. Since 1952, hundreds of orthopedic surgeries have been performed with success using donated tissues and materials from bone banks. The purpose of the present study was to verify the absorption time of xenografts screws made of bovine cortical bone, inserted in the greater tubercule. The humerus of seven dogs in comparison with stainless steel screws. The results showed that screws made from bovine cortical bone used in the humerus of dogs were incorporated within a period of 30 to 60 days with no severe periosteum reaction.
