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 Trigon®also offers a 3-D printed medical grade titanium alloy (TI-6AI-4V) featuring an anatomic design with a three-dimensional scaffold imitating cancellous bone allowing for blood, bone integration and a biologic additive if desired.
Both wedge designs offer integrated screws to maintain implant stability and fusion.
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.
*Titanium wedges will be available in April 2021.
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.
