Intended Use

The Memometal Technologies' SubFix Arthroereisis Implant is intended to treat the hyperpronated foot and stabilize the subtalar joint. It is intended to block forward, downward and medial displacement of the talus, thus allowing subtalar joint motion but blocking excessive pronation and the resulting sequela. The SubFix Arthroereisis Implants are intended for single use only.

Device Story

SubFix Arthroereisis Implant is a one-piece, cannulated, threaded screw device; manufactured from medical grade Titanium Alloy (Ti6Al4V); available in 5 sizes (6.5 mm to 11.5 mm diameter). Device is implanted into the sinus tarsi of the foot by a surgeon; functions by blocking forward, downward, and medial displacement of the talus; allows subtalar joint motion while restricting excessive pronation. Intended for single use. Provides mechanical stabilization to treat hyperpronated foot conditions.

Clinical Evidence

Bench testing only. Equivalence demonstrated via engineering analysis and material comparison to predicate devices.

Technological Characteristics

One-piece cannulated, threaded screw implant; material: medical grade Titanium Alloy (Ti6Al4V); titanium color anodized; 5 sizes (6.5 mm to 11.5 mm diameter); mechanical fixation device.

Indications for Use

Indicated for patients with hyperpronated foot requiring stabilization of the subtalar joint to block excessive pronation and associated sequelae.

Regulatory Classification

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.

# Indications for Use:

The Memometal Technologies' SubFix Arthroereisis Implant is intended to treat the hyperpronated foot and stabilize the subtalar joint. It is intended to block forward, downward and medial displacement of the talus, thus blocking excessive pronation and the resulting sequela.

The SubFix Arthroereisis Implants are intended for single use only.

## Comparison to Predicate Device:

The Memometal device has numerous similarities to the predicate devices which are summarized here. The SubFix device and predicate devices K960692 KMI Subtalar MBA® Arthroereisis Implant (now owned by Intregra) and K031155 Osteomed Talar-Fit™ Subtalar Arthroereisis Implant have the same indications for use and share technical characteristics of being cannulated, threaded screw implants. Each device is placed into the sinus tarsi of the foot, allowing subtalar joint motion while blocking excessive pronation. Most systems are cannulated for ease of implantation. The SubFix device and predicate device K032902 Nexa Orthopedics. INC Subtalar are comparably sized. The SubFix device and predicate devices K041289 Arthroereisis Implant Talus of Vilex (TOV) K080280 Instratek, Inc. Sub-Talar Lok, Model 7-11 mm have similar characteristics of being is titanium color anodized.

## Performance Data:

An engineering analysis and a material comparison to various predicate devices were used to help demonstrate equivalence.

#### Summary:

The Memometal device and the predicate devices have the similar design characteristics and intended use. The new device is substantially equivalent to the predicate devices and should not introduce new concerns in terms of safety or effectiveness.
