Proven Fixation and Stability3

Zimmer Biomet’s Trabecular Metal Reverse Shoulder System presents a comprehensive solution to meet the demands put on reverse shoulder systems.1,2  These objectives include: returning cuff-deficient patients to simple activities of daily living, optimizing range of motion in the face of glenoid erosion, and tuberosity repair in complex fractures. Our Trabecular Metal base plate provides superior glenoid stability1 while the 60 degree humeral components reduce the likelihood of scapular notching.2,3

Trabecular Metal material supports vascularization and biologic in-growth4-7

  • Greater screw engagement and less bone removal than convex base plate designs8
  • Personalized glenoid component planning, sizing and positioning when used with Zimmer Biomet PSI Shoulder
  • Center post lengths up to 30mm maximize bony engagement to minimize base plate micromotion
  • Center of rotation (COR) lateral offset counters glenoid erosion2


Reduced likelihood of scapular notching6-8

  • Less than 1% grade 3 and 4 notching at 16 months. Other studies have reported 6% or more2,10,11
  • Glenosphere COR lateral offset and inferior overhang reduce probability of impingement with the scapular pillar2
  • Humeral component angle of 150° helps provide greater clearance during adduction versus a “Grammont” prosthesis2

Trabecular Metal Reverse Humeral Stem facilitates strong fixation, healing, and enhanced range of motion

  • 7 years of clinical history with over 32,000 global implantations
  • Trabecular Metal material’s scaffold facilitates vascularization and biologic in-growth1-4 
  • High coefficient of friction between Trabecular Metal material and cancellous bone to enhance tuberosity fixation in 3- and 4-part fractures 
  • Extensive humeral liner and spacer combinations, ranging between +0mm and +18mm, to enable proper deltoid tensioning
  • Precise retroversion control optimizes subscapularis and teres minor tension, to enhance internal and external rotation

Non-Porous Humeral Stem portfolio designed to precisely match a range of humeral canal sizes12

  • 6 and 8mm stems to accommodate the smaller patients
  • 200mm stems to facilitate revision from total shoulder to reverse shoulder arthroplasty 
  • Intraoperative flexibility between Non-Porous Reverse and Trabecular Metal Reverse humeral stems utilizing shared instrumentation
