Abstract
A press to form a composite acetabular allograft cup for use in hip replacement surgery is disclosed. The acetabular cup formed by the press comprises bone cement and cancellous bone chips. The press includes a two-piece mold for forming the acetabular cup. The mold is removable from the press and may be available in many different sizes to accommodate a range of patients. A screw-type compression means is utilized to force the acetabular cup into the desired shape. A compression gauge allows the operator to monitor the pressure applied as the acetabular cup is formed to prevent excessive crushing of cancellous bone chips. Breaking jaws are used to separate the acetabular cup from the upper portion of the mold after the bone cement has set and the acetabular cup is formed.
