Pref. binder is gelatin, polyvinylpyrrolidone or a polylactide. The stopper may contain an antibiotic, esp. an aminoglycoside, partic. gentamycin sulphate, in amt. of 50-500 mg (100-300 mg). The compsn. contains 80-99 % of tri-Ca phosphate, 18-0.5% of binder and 2-0.5% of water. ADVANTAGE - The bone cavity can be completely filled with cement, without preventing the sec. fixing.
