Gypsum bone cement with biomimetically grown nano-textured apatite was successfully used as a drug delivery vehicle in addition to its cementation effect. This is attributed to the add-value of the nanotextured apatite spherolites that can be used as drug carriers, where the sorption of gypsum cement results in the slow release of the drugs.
