The Trigon® Stand – Alone Wedge Fixation System for use in both Evans and Cotton Osteotomies offers correction and superior fixation without the need for plating.
- The screw system sets are modular supporting surgeon preferences. Size specific screw caddies incorporating color coded drills, drill guide, countersinks, drivers, and k-wires.
- The HealixTM Cannulated Compression Screws are Self-Drilling and Self-Tapping.
- Dual Pitch “Double Start” Threads.
- The wedge will be the second lower extremity implant to be Structurally Encoded for Unique Device Identification (UDI) with a patented tantalum structural encoded identifier.
- The wedge uses the highly advanced interbody fusion material, PEEK-OPTIMA® HA Enhanced compound (Hydroxyapatite).
- By utilizing the PEEK-OPTIMA® HA Enhanced compound, the device system takes advantage of the material’s osteoconductive properties that promote bidirectional bone healing and improved fixation without introducing material-related bio-incompatibility reactions.


- The smooth back surface design reduces soft tissue irritation in addition to being leveled to the osteotomy site without the need for additional plate fixation.
- The wedges are available in multiple sizes and footprints addressing unpredictable anatomical circumstances providing a precise and reliable correction.
- The ergonomic instrumentation allows for accurate insertion and precise screw placement.
