In2Bones Global, Inc. today announces the U.S. launch of the Avenger Radial Head™ Prosthesis System for primary and revision joint replacement of the radial head. The new prosthesis restores elbow joint function and provides several advantages to surgeons and patients compared with current prosthetic systems. It is the first radial head implant to include sterile, single-use instrumentation.

The modularity of the new Avenger Radial Head Prosthesis System — with multiple, highly-polished head and stem sizes — enables surgeons to restore the appropriate height of the radius, which may aid in elbow stability. The new System is also designed with a smooth stem, shown in multiple long-term studies to provide better clinical outcomes than press-fit, ingrowth radial head implant designs.1, 2

The elbow joint is often difficult to access during surgery due to swelling and inflammation caused by trauma. The Avenger System resolves this with tapered and short stem options, allowing for easier insertion and improved implant stability.

“I choose smooth stem radial head implants for my patients because they have shown to have better long-term results,” says Korsh Jafarnia, M.D., orthopedic surgeon and specialist in the hand and upper extremities at Houston Methodist Orthopedics & Sports Medicine. “The In2Bones Avenger Radial Head System is a modern, smooth stem design that is easier to implant due to the tapered and shorter stems.”

Radial head replacements are often performed during trauma surgery with little advanced notice. Thus, there can be tremendous benefits to providers who select implants that include sterile, single-use instruments. Benefits include:

  • Cost savings of as much as $400 per surgery
  • Increased efficiencies because long lead times and delays related to on-site sterilizing processes are bypassed
  • Reduced risks of surgical site infections (SSIs) post-operatively

“Having the instruments and implants sterile and ready to use provides costs savings for my hospital, and assures me that the system will be ready when I’m called in for surgery,” Dr. Jafarnia notes.

“Currently, radial head implant suppliers ship non-sterile instrument sets nationwide for short-notice cases, which can cause potential delays and can increase costs,” explains Jon Simon, Sr. Vice President of Marketing at In2Bones. “The Avenger Radial Head System can be placed on shelves and be ready for immediate use, on-demand. Additionally, surgeons and caregivers can be assured that the sharp, precision instrumentation will only ever contact one patient.”
