System consists of boot stabilized on distal tibia, connected to distal ring around foot via carbon fiber rods. Foot stabilized to distal ring using Kirshner wires (K-Wires). Used in clinical/surgical settings by surgeons. Provides stable distal support for foot pathology; reduces need for multiple tibial surgical interventions required by traditional ring systems. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Materials: 6061 Aluminum, ABS plastic, carbon fiber rods, FR10/11 laminate, ASTM F 17-4 Stainless Steel fixtures. Mechanical stabilization system using external boot and rod-to-ring fixation. Non-powered, manual surgical device. ## Regulatory 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. ## Reference Devices - Kirshner Wires (K-Wire) ([K960023](/device/K960023.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Presently liizarov or Sheppard Rings are used for this purpose and require multiple avenues of surgical intervention in the tibia to stabilize the distal support ring. With the E-Z Frame system a boot is stabilized on the distal leg (tibia) and further stabilized to the distal ring about the foot with carbon fiber rods that are attached to the boot and ring respectfully. Light weight materials are employed using 6061 Aluminum, ABS plastic, carbon fiber rods, FR10/11 laminate and small ASTM F 17-4 Stainless Steel Fixtures. The foot is stabilized to the distal ring using Kirshner Wires (K-Wire) purchased from PROMEX of Indianapolis, IN under 510 K: K960023. The boot utilized to stabilize the device on the tibia is purchased and modified from Darco International of Virginia. Indications for Use: - 1. Triple arthrodesis - 2. Isolated rearfoot arthrodesis - 3. Midfoot arthrodesis - 4. Comminuted trauma - 5. Diabetic Charcot reconstruction - 6. Most foot pathology not requiring fixation above the ankle ## Contact Information: If further information is required, please contact Dr. Louis A.

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.
