Abstract: A method of treating a fracture includes creating an access path to a fracture site in a bone and inserting a guidewire through the access path into the fracture site is provided. The method includes the steps of positioning a cannulated drill bit having a distal end including helical flutes configured for drilling through bone over the guidewire into the fracture site, and advancing the drill bit to create a passageway in the bone configured to receive a screw. Positioning a cannulated inflatable bone tamp over the guidewire and inflating the inflatable bone tamp to compress at least a portion of the bone in or near the fracture site so as to create a void. Delivering a bone void filler into the void through the access path to fill the void. Systems and kits are disclosed.

Abstract: Calcium-strontium-hydroxyphosphate (strontium-apatite-) cement preparations are described, comprising a powder mixture, which contains molar quantities of the components calcium (Ca), strontium (Sr) and phosphate (P) in the mixture in the ranges 1.00<Ca/P?1.50 and 0<Sr/P<1.5, together with an alkali salt or an ammonium salt of phosphoric acid, and with water and/or an aqueous solution. The powder mixture particularly contains, as the Ca-component, Ca3(PO4)2 (TCP), and as the Sr-component SrHPO4 and/or Sr3(PO4)2 and optionally additional SrCO3. As the aqueous mixing solution for the formation of the strontium-apatite cement, an aqueous solution of an alkali salt or an ammonium salt of the phosphoric acid is suitable.
