 Cement augmentation is believed to increase the bone implant interface and therefore decrease the risk of implant cut-out of the femoral head. The cement used in previous studies has produced heat and thermal necrosis on bone cells. The cement used in this study TraumaCemV is manufactured specially for this implant and for the augmentation of this implant. TraumaCemV sets under low temperature 40 degrees Celsius and we do not anticipate any heat necrosis. The volume effect of the cement could theoretically also damage the blood flow in the femoral head. There have been no negative effects in big series of patients operated with this technique.
