6mm Wedge Parallel PEEK Small Single Joint Lesser Metatarsal The Trigon HA Stand-Alone Wedge Fixation System is intended to be used for internal bone fixation for bone fractures or osteotomies in the ankle and foot, such as: • Cotton (opening wedge) Osteotomies of the Medial Cuneiform • Evans Lengthening Osteotomies • Subtalar Fusion • First Metatarsal-Cuneiform Lengthening Arthrodesis • Calcaneocuboid Arthrodesis • Calcaneal Z Lengthening Osteotomies • MTP Lengthening Arthrodesis • Lesser Metatarsal-Cuneiform Lengthening Arthrodesis • Navicular-Cuneiform Arthrodesis • Talonavicular Arthrodesis The Trigon HA wedges are intended for use with ancillary fixation. The Trigon HA Stand-Alone Wedge Fixation System is not intended for use in the spine.
A non-customized device intended to be implanted between the severed ends of a long bone (e.g., femur, tibia) following osteotomy to help facilitate bone fusion and alignment; it is typically used with a plating fixation system and may be used in association with a bone substitute/graft. The device is typically designed as a small, wedge-shaped cylinder (or other geometric form) and is made of synthetic polymer [e.g., polyetheretherketone (PEEK)].
