Calcium sulfate composition with controlled working time for bone treatment

摘要

A gypsum composition for bone restoration operations having a controlled working time, setting time and semi-solidification time is designed. The gypsum composition is prepared by mixing an orthopedic gypsum and an aqueous solution in a weight ratio to form a semisolid substance which is to be injected into a patient under treatment. The aqueous solution contains serum, blood plasma, or whole blood, which is preferably taken from the patient under treatment.
