Pinnacle™ now with Gription™ Coating

Gription - Feel the Difference!!!

DePuy Orthopaedics, Inc., recently announced that Gription™ Porous Coating, a proprietary cementless implant interface engineered to enhance fixation and maximize tissue ingrowth, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for use on the company’s proven Pinnacle®
Acetabular Cup System. This regulatory clearance has paved the way for an immediate product launch in the United States. This product is now available in Ireland.

“A successful cementless hip replacement is based on the immediate fixation and longterm integration of the patient’s bone to the implant components,” explained George Grobe, Ph.D., Vice President of Research, DePuy Orthopaedics, Inc. “Gription Porous Coating represents a compelling technological advance for many patients who suffer from degenerative hip disease.”

Gription Coating technology differs from previous generation coatings due to its high coefficient of friction and engineered pore form featuring 63% porosity and 300-micron average pore size. The intended result is a secure, stable fit, which may allow patients to more quickly and confidently resume activities of daily living.


About Gription Porous Coating:

Gription Porous Coating is made of a patent-pending commercially pure titanium alloy structure, and is designed for use on the company’s Pinnacle Acetabular Cup System. Applied through a proprietary manufacturing process developed by DePuy, this new implant-coating technology represents an innovative option in cementless fixation technology for patients undergoing primary or revision hip arthroplasty. Cementless hip implants rely on biological fixation. An implant with a sandpaper-like surface provides a good platform for this ingrowth. Gription coating achieves this by covering the implant with pores, creating a rough surface that helps the patient’s bone grip with the implant. The performance of hip replacements depends on age, weight, activity level, and other factors. There are potential risks and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can tell whether hip replacement is right for a patient.
