Device Facts

• Record ID: K032169
• Device Name: CARBON FIBER COMPOSITE CIRCULAR FIXATION (CIRFIX) DEVICE (HALF RING)
• Applicant: Cyberorthology, Inc.
• Product Code: LXT · Orthopedic
• Decision Date: Sep 22, 2003
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3030
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Open and closed fracture fixation, nonunion, precise control of bone segments location including angulation, rotation, translation, lengthening, and shortening. The External Fixator also aids correction of bone deformities or defects associated with fractures and other pathological conditions of bone. The limb function is preserved if the External Fixator is properly applied.

Device Story

CIRfix is a radiolucent carbon fiber composite circular half-ring external fixator. Used in hospitals and patient environments by orthopedic surgeons/clinicians to manage bone fractures, nonunions, and deformities. Device provides structural support for bone segment manipulation (angulation, rotation, translation, lengthening, shortening). Operates as a mechanical frame component; integrates with standard external fixation hardware (clamps, rods, pins, bolts). Provides rigid stabilization while allowing radiolucency for imaging. Benefits include improved strength-to-weight ratio compared to traditional metallic fixators, facilitating safe patient mobility and bone healing.

Clinical Evidence

Bench testing only. Performance compared to predicate devices using ASTM F-1746 standards, including compression stiffness, 3-point bending, cantilever bending, and wire pull-out tests. Results indicate 15-20% performance superiority over predicate devices.

Technological Characteristics

Radiolucent carbon fiber composite; >62% carbon fiber content; circular half-ring geometry; non-sterile; compatible with standard external fixation hardware (clamps, rods, pins). Mechanical performance validated via ASTM F-1746 testing.

Indications for Use

Indicated for humans of any gender at advanced walking age requiring open/closed fracture fixation, nonunion treatment, or correction of bone deformities/defects via external fixation.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.
