A bone cement formulation comprising: (a) magnetic calcium phosphate nanoparticles present in an amount of 5.0-95 wt. % and having a largest linear dimension of 150 nm to 50 microns; (b) polymerizable acrylate monomer present in an amount of 5.0-95 wt. %; and (c) polyacrylate polymer present in an amount of 0-80 wt. % and having a largest linear dimension from 5.0 to 500 microns. Upon exposure to an alternating magnetic field the formulation is heated which results in polymerization of the acrylate monomer component. The formulation may also be polymerized via the use of chain polymerization initiators.

Bone cements containing magnetic calcium phosphate nanoparticles

The present disclosure relates to a bone fracture risk assessment method and system. The method may include generating a volumetric model corresponding to a three-dimensional image of a bone structure for each bone structure in a set of bone structures. The method may further include defining a vector of variables for each bone structure. Each variable in the vector of variables may include a three-dimensional position of one of a number of volumetric vertices and at least one parameter associated with the one volumetric vertex. The method may include generating a set of individual vectors and performing variable reduction on the set of individual vectors. The method may further include determining a discriminator based at least in part on a result of the variable reduction.
