Covestro polycarbonates instrumental to orthopedic surgery innovation

Share

Orthopedic implants are helpful in restoring the quality of life for patients suffering from pain and reduced mobility. Bio2 Technologies of Woburn, Mass. has developed Vitrium Bioactive Glass Implants that are an alternative to allograft and porous metals. In addition to this innovative material, the company is also taking a novel approach to the surgical procedure with plans to replace stainless steel instruments used in two implant applications with instruments made of Covestro polycarbonate.

An instrument set used in conjunction with orthopedic implant surgery consists of a number of templates that help the surgeon determine the appropriate implant to achieve the desired correction. Traditionally, stainless steel instruments are used but these instruments are more expensive and must be sterilized before each procedure. Instruments formed from Makrolon Rx1805 polycarbonate are disposable – a more convenient option for hospitals and surgical centers.

Bio2 Technologies’ Vitrium C and Vitrium E implants have received FDA clearance and are currently available in the U.S. for reconstructive surgery of the extremities. Bio2 Technologies plans to offer disposable polycarbonate instruments following completion of a packaging and sterilization validation study, which is expected mid-year.

“Covestro provided mold flow analysis and made recommendations related to mold construction,” said Art O’Dea, VP of Operations and Legal Affairs at Bio2 Technologies. “This technical support was very valuable,” said O’Dea.

“Covestro is well-known for going the extra mile to support our customers,” said Anthony Leo, field market development, Polycarbonates at Covestro. “In this case, we were able to leverage our substantial materials expertise to help Bio2 Technologies achieve its vision for a disposable instrument kit that would complement its Vitrium C and E Wedges.”

Makrolon Rx1805 medical-grade polycarbonate is part of Covestro’s broad portfolio of polycarbonate resins. Thanks to its documented biocompatibility, this grade offers good chemical resistance and is often used in medical technology applications that require contact with body fluids.
