Indications for Use
The Newfix® External Fixation System, consisting of axial fixators and frame components, is indicated for stabilization of open and/or unstable fractures where soft tissue injury precludes the use of other fracture treatments such as IM rodding or casting. NEWFIX® External Fixation System is intended for the fixation and for temporary or extended stabilization in cases such as: open fractures, closed fractures, poly-trauma fractures, supplement in the stabilization of minimal fixations in intra and extra articular fractures.
Device Story
Modular external fixation system; components include clamps, distractors, pins, carbon fiber rods, stainless steel tubes. Used in orthopedic/trauma settings for fracture stabilization. Physician assembles frame constructs using clamps (rod-to-rod, pin-to-rod) and fixation pins (smooth or self-drilling/self-tapping with diamond tip). System provides temporary or extended stabilization for fractures where internal fixation or casting is contraindicated. Benefits include modularity, frame construction flexibility, and stabilization of complex fractures. Supplied non-sterile for single-patient use.
Clinical Evidence
Bench testing only. Testing included validation of locking mechanisms per ASTM F 1541 and engineering analysis comparing Newfix components to Orthofix predicate devices. Materials and mechanical performance were verified using force verification machines and torque wrenches.
Technological Characteristics
Modular system; materials: Carbon fiber, Stainless Steel 17-4PH (AISI 630), Stainless steel 304, 316LS, Titanium alloys, Aluminum 6061-T6. Components: clamps, distractors, pins, rods. Pins: smooth/self-drilling/self-tapping with diamond tip. Standards: ASTM F 1541 (External Skeletal Fixation Devices), ASTM E 4 (Force Verification). Non-sterile, single-use.
Indications for Use
Indicated for stabilization of open/unstable fractures in pediatric and adult patients where soft tissue injury precludes IM rodding or casting; includes open, closed, and poly-trauma fractures, and stabilization of intra/extra-articular fractures.
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.

Dear Mr. Bard:
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. Iisting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
