[Osseointegration of a laser-structured titanium hemispheric acetabulum in the animal experiment].
Eight hemispherical titanium-cups with a new laser structured surface had been implanted in sheeps. Duration of implantation was eight weeks and one year. Analysis and evaluation of the results were done by post-operative x-rays, x-rays of the specimen, macroradiography, microradiography, fluorescencemicroscopy and histology. A quantitative analysis of the bony ingrowth was performed with a computer-aided system. The 8 weeks-cups showed an osseointegration rate of 28.8%, the one year group of 52.1% of the available surface. Bony ingrowth of the laserstructured titanium surface is possible. The laserstructured titanium surface can be used for the cementless fixation of implants.
