Device Facts

• Record ID: K031155
• Device Name: OSTEOMED SUBTALAR IMPLANT SYSTEM
• Applicant: Osteomed LP
• Product Code: HWC · Orthopedic
• Decision Date: Aug 22, 2003
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3040
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Indicated for use in the treatment of the hyperpronated foot and stabilization of the subtalar joint. It is designed to block the anterior and inferior displacement of the talus, thus allowing normal subtalar joint motion but blocking excessive pronation and the resulting sequela. OsteoMed Subtalar Implants are intended for single use only.

Device Story

OsteoMed Subtalar Implant System; titanium alloy spacer for subtalar joint stabilization. Device blocks anterior/inferior talus displacement to prevent excessive pronation while maintaining normal joint motion. System includes implants (6.0-12.0mm diameter; 10.0-15.0mm length), guide wires, cannulated screwdrivers, and sizers. Used by surgeons in clinical settings for foot reconstruction. Single-use device.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and material similarity to predicate.

Technological Characteristics

Titanium alloy bone fixation fastener; diameters 6.0-12.0mm; lengths 10.0-15.0mm. Mechanical spacer design. Single-use.

Indications for Use

Indicated for patients with hyperpronated foot requiring stabilization of the subtalar joint. Contraindications not specified.

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.

Summary:

This submission describes the OsteoMed Subtalar Implant System indicated for use in the treatment of the hyperpronated foot and stabilization of the subtalar joint. It is designed to block the anterior and inferior displacement of the talus, thus allowing normal subtalar joint motion, but blocking excessive pronation and the resulting sequela. OsteoMed Subtalar Implants are intended for single use only.

The OsteoMed Subtalar Implant System is a spacer for stabilization of the subtalar joint made of Titanium Alloy. The OsteoMed Subtalar implants are offered in diameters of 6.0 to 12.0mm and in lengths of 10.0 to 15.0mm. Guide wires, cannulated screwdrivers and sizers will also be a part of the system.

Equivalence for this device is based on similarities in intended use, material, design and operational principle to the Kinetikos Medical Subtalar MBA System (K960692).

Due to the similarity of materials and design to the predicate device, OsteoMed believes that the OsteoMed Subtalar Implant System does not raise any new safety or effectiveness issues.
