## Intended Use

Intended for use in the construction of an external fixator frame for the treatment of pediatric and adult fractures.

## Device Story

Synthes Medium External Fixation System - MR Safe is a modular orthopedic construct for treating stable and unstable fractures. System components include multi-pin clamps (four/six position), combination clamps, open adjustable clamps, dynamization clips, and rod attachments. The system utilizes 8.0 mm carbon fiber rods and 4.0-5.0 mm Schanz screws. All frame elements are constructed from non-magnetic materials to ensure safety within the MR environment. The device is used by surgeons to stabilize bone fractures, allowing for dynamization during the healing process and double stacking of the frame. It provides mechanical support to facilitate bone healing.

## Clinical Evidence

No clinical data provided; bench testing only.

## Technological Characteristics

Constructed from non-magnetic stainless steel, titanium alloy, and cobalt alloy. Modular frame system including clamps, rods, and screws. Designed for MR environment compatibility. No software or electronic components.

## 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.

Regulation Name: Single/multiple component metallic bone fixation appliances and accessories

Regulatory Class: II Product Code: KTT Dated: February 3, 2004 Received: February 4, 2004

Dear Ms. Silvestri:

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.
