Abstract
An acetabular cup structure of the present invention includes a ball-and-socket prosthesis and a liner, where a ball wall of the ball-and-socket prosthesis has a groove formed by connecting at least two continuous straight lines, and the groove connects an outer surface of the ball wall to an inner surface of the ball wall, so that an expandable sheet is formed between the groove formed by connecting the at least two continuous straight lines and having an angle there-between and two ends of the groove that are not connected, and the liner, for connecting a femoral stem, is tightly attached to the inner surface of the ball wall, and when the liner is tightly attached to the inner surface of the ball wall, the liner presses the sheet and extends to the groove, so that the liner is attached to the ball-and-socket prosthesis more tightly.
