Abstract

Calcium sulfate has a long history of safe and effective use for repair of bone defects. However, the poor mechanical and physical properties have limited its clinical use. This project sought to augment the mechanical and handling characteristics of calcium sulfate cement by addition of either 5 and 10 wt% carboxymethylcellulose. Compared to control calcium sulfate, the augmented samples had lower density, higher workability, increased modulus of elasticity, and greater ultimate strength.
