First Successful Surgery Using New Bone Void Filler Performed at RUMC

April 18, 2019 – In a first for Richmond University Medical Center, last week successful hip replacement surgery was performed using a new calcium sulfate bone void filler called InterSep. Board certified orthopedic surgeon, Mark L. Brandon, MD, FAAOS performed the surgery. Dr. Brandon and an orthopedic surgeon in Florida are the first two surgeons in the country to complete procedures using the new material. 

According to Pacific Bioceramics, the product’s manufacturer, InterSep is a 100 percent synthetic calcium sulfate bone void filler that fully resorbs and replaces bone during the healing process. InterSep can be used in a variety of bone and joint replacement surgeries, including at infected bone sites. 

“This new product can help minimize the risk of infection associated with joint replacement surgery such as total knee, total hip, total shoulder and reverse shoulder replacements,” Dr. Brandon said. “The risk of infection with these surgeries is increased in Staten Island because we have higher rates of obesity and diabetes compared to New York City and national averages.” 

According to Dr. Brandon, Intersep consists of calcium sulfate beads that slowly dissolve over the course of six weeks. As the beads dissolve antibiotics are released, reducing the possibility of infection which can cause further complications and hinder the patient’s healing process. 

InterSep is manufactured by Pacific Bioceramics and distributed exclusively by Exactech, a developer and producer of bone and joint restoration products. It is currently available at select hospitals and medical facilities throughout the country. The other surgery using Intercep was performed by Timothy van de Leur, MD, at The Orthopedic Institute in Ocala, Florida. 

“By using this product which releases antibiotics in a timed-release fashion, Richmond University Medical Center is helping our Staten Island patient community by greatly reducing complications such as infection,” Dr. Brandon said.
