ABSTRACT:
A firm but pliable medical device for use as a bone graft substitute or bone graft extender retains its shape without the requirement of a containment device, such as a syringe. Because the device is solid, it is easy to locate or position in-vivo and, in the moist environment of the body, it will hold its shape well, for an extended time. Because the lyophilized pliable medical device is porous, it adsorbs blood and other beneficial cells containing body fluids, such as bone marrow, contributing to its superior bone repair efficacy in comparison to an analogous putty that has not been lyophilized. In addition these lyophilized pliable medical devices are easier to terminally steam sterilize than the analogous putty because there is no moisture present to boil and “blow-out” of the containment device (syringe). The glycerin that is present in the formulation lends pliability but has a low vapor pressure.
