For more than a decade, the radiographic and histologic appearance of a refined calcium sulfate has been studied in various experimental animal models in our laboratory and in clinical applications. This report summarizes our institution’s experience with calcium sulfate as a synthetic bone graft1, a graft expander (the synergistic combination of calcium sulfate with demineralized bone matrix)2-4, and a method for local delivery of antibiotics5-8. Historically, orthopaedic usage of calcium sulfate was popularized by Peltier. Clinically, we have used calcium sulfate to treat numerous osseous lesions and conditions occurring in the axial and appendicular skeleton, including a variety of benign lesions of bone, osseous defects following implant removal, corrective osteotomy sites, spinal fusion sites, graft sites, fracture defects, and osteomyelitic lesions.
