Envejecimiento del cemento óseo de polimetilmetacrilato

Aging of materials is an important factor in the long term behaviour of polymethylmethacrylate (PMMA) bone cementoA new method for evaluating the aging of this material by diferential scanning calorimetry is presented as well as results of measures made on an animal model and using material removed from falled artbroplasties. PMMA aging is nearJy inexistent in tbe first weeks and Iittle after some years.
