DePuy Orthopaedics has received the US Food and Drug Administration (FDA) 510(k) clearance for the use of Gription TF, a titanium foam (TF), in two new implant systems for complex joint replacement procedures.

Gription TF is a highly porous structure made from commercially pure titanium; a corrosion-resistant metal that has high surface roughness and a similar elasticity to bone.

The DePuy Gription TF Acetabular Augment System for hip replacement surgery and the DePuy Universal Gription TF Cones for knee replacement surgery are the implants made entirely from company’s proprietary Gription TF technology.

The Gription TF Acetabular Augment System fills the gap between the acetabular bone and cup in patients with severe bone defects and provides advances in fixation, materials and instrumentation, all of which are critical to achieve successful patient outcomes.

The Universal Gription TF Cones for knee replacement surgery can be used with the tibial or femoral component in patients with marked bone loss, providing surgeons with additional options when faced with a complicated revision total knee replacement.

DePuy Orthopaedics worldwide president David Floyd said DePuy’s Gription TF System features several advances to create customized intraoperative solutions for patients who require complex revision surgery.

"With DePuy’s Gription TF technology, surgeons will be able to more confidently address even the most challenging defects in conjunction with our Pinnacle Acetabular Cup System," Floyd said.
