Detrimental effect of aging on the endurance of bone cement: An in vivo and in vitro study in rabbits
We investigated the effect of aging on the compressive strength of bone cement under in vivo and in vitro conditions. Cement molds were implanted in the dorsum of rabbits and other molds were kept under stable conditions and in darkness. Comparative measures taken at 15 days and 1,3,6,12 and 24 mont...
