The Futura™ Primus Flexible Great Toe (model FGT) is a third generation implant for supplementation of first metatarsophalangeal joint arthroplasty. The implant is constructed from ULTRASIL® medical grade silicone elastomer and includes titanium grommets. The first double-stemmed implant. The Primus is the first double-stemmed implant designed specially for the unique geometry of the first metatarsophalangeal joint. With its dorsal-offset metatarsal aspect, the Primus matches the anatomic position of the proximal phalanx relative to the metatarsal. The patented axial offset hinge design reduces stress on the prosthesis and improves biomechanical function. The inferior aspect of the distal hinge buttress is angled to minimize interference with the flexor hallucis brevis attachment site and the sesamoid apparatus. A highly engineered hinge offers 95 degree range of motion and prevents the grommets from contacting each other. The trapezoidal stem cross section matches the anatomy of the intramedullary canal. Angled proximal stem corresponds with natural metatarsal declination angle.
