## Intended Use

The Great Toe Implant System is indicated for use in the treatment of patients with inflammatory arthritis in the first metatarsal joint in the presence of good bone stock and integrity of the first metatarsal head, along with the following clinical conditions; Hallux valgus, hallux rigidus and an unstable or painful Metatarsal / phalangeal (MTP) ioint.

## Device Story

K2 Hemi Toe Implant System is a polymer prosthesis for the first metatarsal joint; used for treatment of inflammatory arthritis, hallux valgus, hallux rigidus, and unstable/painful MTP joints. Device consists of 4 sizes of implants; designed for press-fit application by surgeons. Modification includes addition of titanium plasma coating to implant surface and removal of spike features. Device functions as a hemi-arthroplasty component to replace the joint surface; intended to restore joint function and reduce pain in patients with sufficient bone stock. Surgical protocol remains identical to predicate systems.

## Clinical Evidence

No clinical data provided; substantial equivalence is based on design, material, and technological similarities to predicate devices.

## Technological Characteristics

Polymer prosthesis for hemi-toe arthroplasty; features titanium plasma coating. Designed for press-fit fixation. Available in 4 sizes. Sterilization and packaging processes are identical to predicate devices.

## Regulatory Identification

A toe joint phalangeal (hemi-toe) polymer prosthesis is a device made of silicone elastomer intended to be implanted to replace the base of the proximal phalanx of the toe.

## Predicate Devices

- Harmos Orthodpedic, Inc., Great Toe Implant System ([K014164](/device/K014164.md))
- Futura Biomedical Hemi Toe implant ([K971047](/device/K971047.md))

#### INTENDED USE

The Great Toe Implant System is indicated for use in the treatment of patients with inflammatory arthritis in the first metatarsal joint in the presence of good bone stock and integrity of the first metatarsal head, along with the following clinical conditions; Hallux valgus, hallux rigidus and an unstable or painful Metatarsal / phalangeal (MTP) ioint.

#### SYSTEM DESCRIPTION

The KMI Great Toe Implant System consists of 4 (four) sizes of toe implants. The implants will now be plasma coated. It is constructed of materials that have a lona clinical history of proven acceptance and performance. This system is intended for press fit use only and will be promoted as such in the Surgical Protocol 81-0065. Engineering drawings of the implant is shown in Exhibit III.

#### EQIVALENCE TO MARKETED PRODUCT

The K2 Great Toe implant has the following similarities to the predicate Great Toe implants which previously received 510/k) concurrence:

- -identical design (with the exception of the elimination of the spike features)
- -identical operating principle / surgical protocol
- -is packaged and sterilized using identical materials and processes

The primary distinct difference is the addition of a titanium plasma coating identical to coatings used in cleared, competitive products. In summary, the extra small K2 Hemi Toe Implant System described in this submission is, in our opinion, substantially equivalent to the predicate device.
