Phosphate Groups

Cement materials have based on calcium sulfate were obtained, which have introduced up to 20 mol. % of phosphate groups to improve their cytocompatibility and solubility. It was found that during exposure of cement materials based on calcium sulfate, containing of 0, 5, 10 and 20 mol. % phosphate - groups, in model solutions SBF (Kokubo solution, simulating the composition of human blood plasma) and DPBS (Dulbecco's phosphate-buffered saline) in dynamics up to 28 days of were formation of a calcium-phosphate layer on the surface of the samples. At the same time, in SBF solution, the process of recrystallization of sulfate and phosphate phases occurs more pronounced than in DPBS solution. In vitro studies on the cell culture of the human osteosarcoma line MG-63, cement samples showed cytocompatibility with the presence of moderate surface matrix properties

Comminuted Fractures

Distal radius fracture alignment and stabilization can be a surgical challenge in the face of severe comminution and bone loss. We describe a technique using a calcium phosphate/sulfate bone cement, as an adjunct to internal fixation. This bone cement is biocompatible, osteoconductive, and sets quickly with an isothermic reaction. The use of bone cement eliminates the need for primary autologous bone grafting and allows for easier reduction and retention of reduction at the time of surgery. Bone cement is employed for the following purposes in comminuted fractures: (1) to fill a void due to lost or crushed cancellous bone, (2) to hold larger unstable fragments while hardware is placed, and (3) to retain fragments too small to take hardware. Available bone cements, studies involving the use of bone cement for distal radius fractures, indications, and surgical technique will be reviewed.

Calcium sulfate/hydroxyapatie (CaSO4/HA) composite bone fillers were fabricated through molding method. Their structure and properties were characterized by infrared spectroscope, scanning electronic spectroscope, x-ray diffraction and degradation test. The results show that HA crystals were attached to the CaSO4 crystals and prevented the growing of sulfate crystals. So their size is shorter than that of CaSO4 crystals prepared from pure CaSO4 semihydrate, and some even had defect. The resorption rate of CaSO4 bone fillers was decreased when HA was incorporated.
