DePuy Synthes Brings Radial Head Prosthesis System to US Market

December 17th, 2013 Gaurav Orthopedic Surgery

radial-head-prosthesis-systemDePuy Synthes, a part of J&J, has launched the Radial Head Prosthesis System in the US for primary and revision joint replacement of the radial head to restore joint function. The system is also indicated for replacement of the radial head for degenerative or post traumatic disabilities, primary replacement after fracture of the radial head, for symptomatic episodes after radial head resection, and revision after unsuccessful radial head arthroplasty.

The Radial Head Prothesis System has a modular two piece design consisting of a radial head and a radial stem that accommodate multiple patient anatomies. The radial head is in the form of a side loading head that allows for in-situ insertion and assembly and requires a smaller incision than a top loading head. The radial head is round and symmetrical to allow for ease of sizing and implantation. It has an integrated connection screw that engages with a taper locking assembly and indicates when the head is locked to the stem.

The radial stem has a fluted design for rotational stability and is available either in straight or curved forms. The straight stem has a beveled tip to allow for insertion into the medullary cavity, whereas the curved tip conforms to the physiological bend of the proximal radius. The stem has a thin collar that helps to guide the head into the stem and the device’s surface is roughened by chemical etching to promote bony growth.
