MTP – MTP I joint prosthesis

An endoprosthesis used in hemiarthroplasty and total toe arthroplasties. This joint prosthesis was developed as an alternative to arthrodesis to allow for unrestricted daily activities and preserve mobility of the first metatarsophalangeal joint.
It consists of a metatarsophalangeal component and a phalangeal component, designed to reconstruct the head of the first metatarsal bone at the base of the proximal phalanx. These two implants replace the metatarsophalangeal joint, preserving full joint function and the sesamoid complex.
The implants are made of a biocompatible material.

Features and Benefits
• Total and unilateral implants for both sides of the joint are provided within a single set.
• For a complete anatomical conformity, implants of different sizes can be used on either side of the joint.
• it is in the form of cannulated system to facilitate implantation.
• Conical dilation requires minimal bone resection while keeping the tissue inserts and sesamoid apparatus in place.
• The dorsal metatarsal cutter guide allows complete cheilectomy of dorsal osteophytes during implantation of the metatarsal component.

Total Arthroplasty
• Painful degenerative metatarso-phalangeal joint.
• Hallux rigidus 3-4. phase.
• Hallux valgus and Hallux Rigidus.
• Painful arthrofibrosis accompanied by hallux limitus.
• Revisions.

Hemi-Arthroplasty
• Hallux vulgus or hallux limitus.
• Hallux rigidus.
• Unstable or painful metatarsal/phalangeal joint.

lndications
• The PIEX MTP System is designed for regeneration of the first metatarsal head and/or the proximal phalanx sole surface.

Contraindications
• Active local or systemic infections.
• Bone quality that prevents the implant from sticking in place.
• Vascular insufficiency, neuromuscular deterioration, and deterioration of musculature in the big toe.
