An acetabular cement splitter is a specialized surgical instrument used in revision total hip arthroplasty to remove the bone cement mantle after a cemented acetabular component has been extracted. It is designed to fragment and split the residual cement, which often remains firmly adhered to the bone, allowing for its safe removal while minimizing damage to the surrounding pelvic bone.

The cement splitter is a key part of the broader "acetabular revision system," which includes specialized instruments for removing various types of well-fixed implants and bone cement. While some advanced systems use ultrasonic tools to cut cement, the manual splitter is a traditional and often essential instrument for this demanding task.
