Abstract

1 page of the number 1 page summary of the invention A disc replacement device based on this invention. It consists of a base. With a geometric shape With a gap in the center in such a way that it penetrates from one external contact surface to the other external contact surface with a rough surface. That can be selected from the embossed lines or manu in a raised manner Higher from such external contact surfaces And at the lateral edge of the herniated disc replacement device, it consists of holes that penetrate from the side edge to the internal surface. By such internal surfaces Provide an accent Groove inward By the distance of the groove inward The distance is greater than the distance of the empty brothel that penetrates from the ground. External contact surface to the other side This invention Focus on the development of the groove in the interior of Internal surface of a herniated disc replacement device This helps to increase the area for bone grafting and reduce slippage during bending surgery to insert the device further into the spinal joints.
