U.S. Launch for DePuy Synthes Trauma Modular Radial Head Prosthesis System

DePuy Synthes Trauma has announced the U.S. launch of a new Radial Head Prosthesis System for primary and revision joint replacement of the radial head to restore joint function. The company says its system offers several benefits over current technologies.

Background

DePuy Synthes Trauma, part of DePuy Synthes Companies of Johnson & Johnson, is a global leader in medical devices used to treat orthopaedic trauma. The company’s fixation products, including screws, plates, nails and other implants, are used to treat fractures, deformities, and tumors related to the shoulder, hand, arms, legs, hip, pelvis, condyles and feet.

The buzzword for the newly announced system is modularity. Its 24 heads and 10 stems allow for 240 possible implant combinations, enabling surgeons to restore the appropriate height, which may aid in elbow stability. The side-loading capability facilitates in-situ insertion and assembly, which may allow for a smaller incision than a top-loading device, while the stem texture ensures a uniform press fit in the radial canal. The system also provides an integrated connection screw to facilitate assembly, along with simple instrumentation.

Physician comments

“This system is a comprehensive solution for the radial head replacement that permits the surgeon to choose whether a long or short stem is best for the proximal radius,” said Harry Hoyen, M.D., Department of Orthopedic Surgery, MetroHealth Medical Center, Cleveland, Ohio and a consultant to the company. “With the system, a novel surface etching permits on-growth and stability, the head element can be placed onto either stem and is designed to take into account the PRUJ and radiocapitellar articulation for each respective size. There also is a side-loading option for intraoperative assembly.”
