Abstract

Various embodiments of tantalum- and/or niobium-containing glasses and cements as well as uses thereof are described herein. For example, in an embodiment, the glasses comprise a transition metal pentoxide such as tantalum pentoxide and/or niobium pentoxide present in the glass in an amount of less than 2.0 mol %, based on the total composition of the glass, glass polyalkenoate cements prepared from such glasses and uses of such cements, for example, for sternal closure or fixation, stabilization and/or repair of a fracture in a bone in the wrist, elbow, knee, shoulder, spine and/or hip.

Abstract

A synthetic graft has a glass composition comprises silicon as a network former and Sr as a stable isotope acting as a network modifier. The composition contains calcium as a network modifier and Zn acting as a as either a network modifier or as a network former. The glass composition may be mixed with a solution of polyalkenoic acid to provide advantageous glass polyalkenoate cements (GPCs). These cements are particularly effective for use as bone cements and fillers in the human skeleton as they set at room temperature, have similar strengths to bone, chemically bond to both bone and surgical metal, and release therapeutic ions, which can assist in wound healing and bone re-growth.
