Optimize patient outcomes across a broad range of indications
Proven Fixation and Stability
Zimmer Biomet’s Trabecular MetalTM 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 stability1while the 60 degree humeral components reduce the likelihood of scapular notching.2,3
- Trabecular Metalmaterial supports vascularization and biologic in-growth4-7
- Greater screw engagement and less bone removal than convex base plate designs8
- Center post lengths up to 30mm maximize bony engagement to minimize base plate micromotion•Center of rotation (COR) lateral offset counters glenoid erosion2
- Personalized glenoid component planning, sizing and positioning when used with Zimmer Biomet PSI Shoulder
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 MetalReverse Humeral Stem facilitates strong fixation, healing, and enhanced range of motion1,2,3
- 7 years of clinical history with over 32,000 global implantations
- Trabecular Metalmaterial’s scaffold facilitates vascularization and biologic in-growth1-4
- High coefficient of friction between Trabecular Metalmaterial 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 MetalReverse humeral stems utilizing shared instrumentation
