title: [Sandblaster or alumina-coated 316 L stainless steel for implantable material in orthopedic surgery. Study on metacarpal bone of sheep].
abstract: We have carried out a study in sheep of the behavior of bone in the presence of two materials, 316 L stainless steel with a surface roughened by sandblasting, and the same type of steel, plasma-coated with alumina. Twelve nails of each type were implanted into the medullary cavities of previously fractured metacarpal bones. The samples were removed after 90 days for six animals and after 180 days for six others. The functional study and the radiographic analysis, as well as the growth of bone around the implants as assessed with a light microscope and with microradiography, did not show any significant difference between both types of temporary implants.
