Zimmerв Nexgenв Trabecular Metal Primary Patella Zimmer Biomet о The nexgen trabecular metal primary patella closely tracks the patellar groove in mid to deep flexion. its dimensions correspond to the articulating geometries of all nexgen femoral components. cancellous bone trabecular metal material fully supported polyethylene polyethylene powder resin is compression molded into the trabecular metal material. Introduction. the nexgen® rotating hinge knee (rh knee) is designed for revision, difficult primary, and limb salvage surgeries in patients with significant bone loss and or ligament deficiencies. although most rh knee surgeries involve revision arthroplasty, this document provides options for all procedure types (table 1).
Total Hip Arthroplasty Trabecular Metal Primary Hip Prosthesis The zimmer nexgen trabecular metal material primary patella mimics the shape of the nexgen patellar groove in mid to deep flexion. this optimizes the patello femoral contact area, where stresses on the patella are the highest. in addition, the nexgen primary porous patella possesses a metal backing with low stiffness, which may further minimize. Zimmer biomet. A unique, highly porous biomaterial. trabecular metal material is 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 biological fixation and vascularization. 1,2 the material has over 20 years. Apply the patella reamer clamp at a 90° angle to the longitudinal axis with the patella reamer insetting guide on the articulating surface. squeeze the clamp until the anterior surface of the patella is fully seated against the fixation plate. the locking screw to hold the instrument place.
