Application of a novel porous tantalum implant in rabbit ...
A new generation of porous tantalum called trabecular metal (TM) came into being, with good biocompatibility, high porosity and stone similar elastic modulus characteristics. Clinically, TMs (such as porous tantalum) are widely used in avascular necrosis of the femoral head, artificial joints, spinal fusion, and other fields.
Trabecular Metal™ Technology | Zimmer Biomet
Zimmer Biomets Trabecular Metal Material is a unique, highly porous biomaterial made from elemental tantalum with structural, functional, and physiological properties similar to that of bone. 1 The material features a 100% open, engineered and interconnected pore structure to support bony in-growth and vascularization. 1,2 The material has over 20 years of demonstrated clinical use in a ...
Modified porous tantalum rod technique for the treatment ...
The porous tantalum rod was combined with endoscopy, curettage, autologous stone grafting and use of stone marrow aspirates from iliac crest aspiration in 58 hips. The 5-year survival based on conversion to total hip arthroplasty was 93.1% and the respective rate based on disease progression was 87.9%.
Use of Porous Tantalum Metaphyseal Cones for Severe Tibial ...
implant, the porous tantalum metaphyseal cone, designed as an alternative treatment for severe tibial stone loss following total knee arthroplasty. Methods: Porous tantalum metaphyseal cones were implanted during fifteen revision total knee replacements in eight women and seven men who had an average age of 68.1 years at the time of the procedure.
Biocompatible Porous Tantalum Metal Plates in the ...
Porous tantalum metal plates have great application potential as a new implant material for internal fixation. Introduction. Tibial fractures are generally caused by high‐energy injuries, and the incidence rate is 16.9/100 000 1. Moreover, nonunion and malunion account for 2%–12% of all fractures of the tibia 2.
