Resumen:
The composition and morphology of bones implanted with stainless steel (316L-SS) and a metal alloy made of zinc, aluminum, and copper (Zinalco) are compared. Small-angle X-ray scattering (SAXS) and nuclear magnetic resonance (NMR) results show that with time Zinalco is corroded and zinc, aluminum, and copper diffuse into the osseous tissue, promoting nonhomogeneous bone. Instead, 316L-SS does not incorporate into bone, and the bone recovers homogeneously at a lower speed. © 2005 Wiley Periodicals, Inc.
