Experimental and clinical performance of porous tantalum in orthopedic surgery
Biomaterials, 2006Porous tantalum, a new low modulus metal with a characteristic appearance similar to cancellous bone, is currently available for use in several orthopedic applications (hip and knee arthroplasty, spine surgery, and bone graft substitute). The open-cell structure of repeating dodecahedrons is produced via carbon vapor deposition/infiltration of ...

Primary human osteoblasts grow into porous tantalum and maintain an osteoblastic phenotype
Journal of Biomedical Materials Research - Part A, 2008 Published in Journal of Biomedical Materials Research. Part A, 2008; 84A (3):691-701 at www.interscience.wiley.comPorous tantalum (Ta) has found application in orthopedics, although the interaction of human osteoblasts (HOB) with this material has not ...

Biomechanical analysis of the osseointegration of porous tantalum implants
The Journal of Prosthetic Dentistry, 2020Although implants containing porous tantalum undergo osseointegration, whether this material significantly alters new bone formation and improves implant stability during healing in comparison to titanium is unclear.The purpose of this in vivo study was to determine the influence of the inclusion of porous tantalum into a dental implant on the ...

Porous tantalum in spinal surgery: an overview
European Journal of Orthopaedic Surgery & Traumatology, 2015Porous tantalum is an open-cell metal structure that approximates the appearance of human cancellous bone. It has a low modulus of elasticity, close to that of subchondral and cancellous bones, leading to better load transfer and minimizing the stress-shielding phenomenon.

Porous tantalum in hip and knee reconstructive surgery
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2008AbstractConventional porous‐coated joint prostheses used in hip and knee reconstruction have demonstrated good clinical results, however, these implants possess some inherent shortcomings such as low volumetric porosity, suboptimal frictional characteristics, and higher modulus of elasticity relative to that of bone.

Applications of Porous Tantalum in Total Hip Arthroplasty
Journal of the American Academy of Orthopaedic Surgeons, 2006Porous tantalum is an alternative metal for total joint arthroplasty components that offers several unique properties. Its high volumetric porosity (70% to 80%), low modulus of elasticity (3 MPa), and high frictional characteristics make it conducive to biologic fixation. Tantalum has excellent biocompatibility and is safe to use in vivo.

Porous Tantalum Patellar Augmentation
Clinical Orthopaedics and Related Research, 2006Trabecular metal augmentation of bone defects has been associated with favorable bone ingrowth. Animal studies also suggest fibrous tissue attachment to trabecular metal can be achieved. We treated 16 patients with total knee arthroplasty (18 knees) with severe patellar bone loss using trabecular metal patellar reconstruction. The patients were divided

Formability of Porous Tantalum Sheet-Metal
Journal of Manufacturing Science and Engineering, 2011Over the past 10 years, a novel cellular solid, Trabecular MetalTM (TM), has been developed for use in the orthopedics industry as an ingrowth scaffold. Manufactured using chemical vapor deposition (CVD) on top of a graphite foam substrate, this material has a regular matrix of interconnecting pores, high strength, and high porosity.
