DePuy Synthes Trauma Rolls Outs Joint Replacement System in U.S.

Dec. 20, 2013

Johnson & Johnson subsidiary DePuy Synthes Trauma announced the U.S. launch of its Radial Head Prosthesis System for primary and revision joint replacement. The system is indicated for use in patients with degenerative or post-traumatic disabilities presenting with pain, crepitation and decreased motion at the radiohumeral and/or proximal radioulnar joint, as well as visible joint destruction and resistance to traditional treatment.

The new prosthesis system consists of 24 different heads and 10 different stems, letting surgeons choose between 240 potential implant combinations. The system also lets surgeons take into account the PRUJ and radiocapitellar articulation for each size and provides the option of side loading, which facilitates in-site insertion and assembly. The new loading option may enable surgeons to make smaller incisions, the company said.

The texture of the implant’s stem promises a uniform fit in the radial canal, and the ability to restore the appropriate height may aid in elbow stability, the company added.
DePuy’s system is currently available only in the U.S., though the devicemaker is working on expanding into other markets. — Lena Freund
