Toe digit joint implant Futura™ MHT Tornier
Futura™ MHT


The Metal Hemi Toe (Model MHT) is a single stemmed resurfacing prosthesis for the first proximal phalanx designed to supplement first metatarsal phalangeal joint arthroplasty. The implant is manufactured from cobalt chrome to provide a wear resistant articular surface. A section of the intramedullary stem and the surface contacting the resected base of the proximal phalanx are coated with a titanium plasma spray to encourage osseous integration. Cobalt chrome provides a wear resistant articular surface. The implant is manufactured in three sizes and is supported with a simple, custom designed instrumentation set. Trapezoidal articular surface matches the geometry of the resected base of the proximal phalanx and is anatomically congruent to the metatarsal head. The thin plantar aspect of the articular surface allows for preservation of the flexor hallucis brevis attachment site with up to 3mm of joint decompression. A short, trapezoidal stem provides a better anatomic fit in the intramedullary canal, with an angulation to help protect the plantar cortex. The dorsal aspect of the implant is rounded to reduce impingement on the metatarsal head. The stem is designed to facilitate revision to a Primus UltraSil implant.
