Intended Use

Futura Biomedical Classic Great Toe Implant is indicated for: - Hallux limitus or hallux rigidus - Painful rheumatoid arthritis - Hallux abducto valgus associated with arthritis - Unstable or painful joint from previous surgery

Device Story

Classic Great Toe Implant is a double-stemmed silicone prosthesis; functions as a dynamic joint spacer for first metatarsophalangeal joint arthroplasty. Implanted surgically by placing stems into the intramedullary canal of the resected first metatarsal head and base of the proximal phalanx. Device provides mechanical support and joint stabilization; intended for long-term implantation (>30 days). Benefits include pain relief and restoration of joint function for patients with degenerative or post-surgical joint conditions. Device is a size-expanded version of the predicate, adding a larger size (size 60) to the existing range (20, 30, 40, 50).

Clinical Evidence

No clinical data provided; substantial equivalence based on design, material, and intended use similarities to the predicate device.

Technological Characteristics

Double-stemmed silicone prosthesis; constrained design; intramedullary fixation; five sizes (20, 30, 40, 50, 60); single-use; sterile.

Indications for Use

Indicated for patients with hallux limitus, hallux rigidus, painful rheumatoid arthritis, hallux abducto valgus associated with arthritis, or unstable/painful joints resulting from previous surgery.

Regulatory Classification

Identification

A toe joint polymer constrained prosthesis is a device made of silicone elastomer or polyester reinforced silicone elastomer intended to be implanted to replace the first metatarsophalangeal (big toe) joint. This generic type of device consists of a single flexible across-the-joint component that prevents dislocation in more than one anatomic plane.
