Self-hardening bioactive cement compositions with partially deacetylated chitin as bone graft substituents

摘要

A bone cement composition kit for the medical treatment of bone healing, comprising: a. a solid fraction comprising partially deacetylated chitin (QPD) with a degree of deacetylation in the range of 40-75% and calcium phosphate; b. an acidic liquid fraction comprising water and an acid; said fractions being provided in separate vials, to be mixed before use, in which the weight ratio of the solids fraction with respect to the liquid fraction is in the range of 1: 2 to 1: 3.
