## Intended Use

The Futura Biomedical Arthrorisis Implant is intended to treat hyperpronated foot and stabilize the subtalar joint. It is intended to block forward, downward and medial displacement of the talus, thus allowing normal subtalar joint motion but blocking excessive pronation and the resulting sequela. Examples include: Flat foot treatment in children and adolescents Congenital flat foot Unsuccessful long term orthopaedic treatment (shoes, insoles ...) Tarsal coalitions Painful flat foot Supple deformity in posterior tibial tendon dysfunction Paralytic flat foot Subtalar instability

## Device Story

The Futura Biomedical Subtalar Arthrorisis Implant is a single-piece titanium (6AL-4V ELI) device surgically implanted into the sinus tarsi of the foot. It functions as a mechanical spacer to maintain joint space and limit excessive pronation of the talus relative to the calcaneus while preserving normal subtalar joint motion. The device is available in six sizes and is intended for long-term implantation (exceeding 50 days). It is used by orthopedic surgeons to treat various flat foot conditions and subtalar instability. By blocking forward, downward, and medial displacement of the talus, the implant stabilizes the joint and prevents the sequelae associated with excessive pronation.

## Clinical Evidence

Bench testing only. No clinical data provided.

## Technological Characteristics

One-piece implant; material: Titanium 6AL-4V ELI; fixation: screw; constraint: non-constrained; dimensions: 6 sizes; intended for long-term implantation (>50 days); single-use; sterile.

## Regulatory Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.

## Device Description:

The Futura Biomedical Implant is a one-piece device made of Titanium (6AL-4V ELI) intended to be implanted into the sinus tarsi of the foot. The implant is designed in 6 sizes. The implant which is used in the treatment of excessive motion of the talus relative to the calcaneus acts as a spacer for the joint, maintaining the joint space, allowing for range of motion, but limiting excessive pronation.

#### Indications for Use:

The Futura Biomedical Arthrorisis Implant is intended to treat hyperpronated foot and stabalize the subtalar joint. It is intended to block forward, downward and medial displacement of the talus, thus allowing normal subtalar joint motion but blocking excessive pronation and the resulting sequela. Examples include:

Re: K032902

Trade/Device Name: Subtalar Arthrorisis Implant Regulation Number: 21 CFR 888.3040 Regulation Name: Smooth or threaded metallic bone fixation fastener Regulatory Class: II Product Code: HWC Dated: September 16, 2003 Received: September 17, 2003

Dear Ms. Focht:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
