In Harmony with Natural Anatomy
Created to meet surgeon and patient needs, this ankle implant features a low profile design, lateral surgical approach and industry-first Prolong® Highly Crosslinked Polyethylene.
Anatomy
- Ankle
Procedure
- Total Ankle Replacement
Advanced implant designed to last
- Prolong Highly Crosslinked Polyethylene bearing surface to reduce volumetric wear.3,4
- Trabecular Metal has a high coefficient of friction vs. cancellous bone for stable initial fixation.5
- Reduced bony resection with the TM Ankle leaves more bone, which Statistically significantly increases bony support when compared to the alternative, flat resection.2
System Features
Lateral transfibular approach for peace of mind
Anatomic center of rotation is fully visualized and can be more precisely replicated.
Simplified Precision
Proprietary alignment and bone preparation system are intended to make surgery more repeatable and reproducible by providing rigid fixation for bone and instruments.
Endurance
Advanced implant designed to endure. Prolong Highly Crosslinked Polyethylene bearing surface engineered to reduce volumetric wear.
