1. Based on the classic theory of EXETER polishing design;
2. Highly polished surface minimizes the wear between the prosthesis and cement;
3. Double cone collar-free design: Allows the prosthesis to sink slightly in the cement sheath and become tighter under pressure;
4. No thigh pain;
5. No prosthesis loosening;
6. No osteolysis;
7. Equipped with distal plugs and a central control body for the third-generation bone cement technology.
