bone cements

Chitosan and chitosan oligosaccharides in antibiotic-loaded bone cement
Orthopedic infections can be treated with antibiotic-loaded bone cements. However, due to the growing number of resistances, new formulations are needed to e.g. improve the drug release. For this reason, dual-antibiotic bone cement containing chitosan and chitosan oligosaccharide was prepared in the presented study.

Carboxymethyl chitosan alginate as an enhancer of bone cement repair activity
Critical bone defects often require the use of bone grafts or artificial bone substitutes such as calcium phosphate cement (CPC) or magnesium phosphate cement (MPC). In the study presented here, MPC is modified with CMC and sodium alginate to form a novel bone cement and its properties are investigated in vivo and in vitro.
