• Attributes: Therapeutic

Intended Use

The Hoffmann® II Compact™ Baltimore Coupling is intended to be used with the components of the Hoffmann® II Compact™ External Fixation System and in conjunction with the half pins or transfixing pins of the Hoffmann® External Fixation System. It is intended to be used in the stabilization of open and/or unstable fractures and where soft tissue injury may preclude the use of other fracture treatments such as IM rodding, casting, or other means of internal fixation.

Device Story

The Hoffmann® II Compact™ Baltimore Coupling is a mechanical component for the Hoffmann® II Compact™ External Fixation System. It functions as a rod-to-rod coupling to stabilize bone fractures. The device is a modification of the predicate rod-to-rod coupling, featuring a revised profile, an added lip for increased resistance to rod slippage, and chamfered edges to facilitate rod insertion. It is used by surgeons in clinical settings to construct external fixation frames for patients with open or unstable fractures. The device provides mechanical stability to the fracture site, serving as an alternative to internal fixation or casting when soft tissue conditions are compromised.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: stainless steel and aluminum. Function: rod-to-rod coupling for external fixation. Design features: modified profile with added lip for slippage resistance and chamfered edges for rod insertion. Mechanical properties comparable to predicate.

Indications for Use

Indicated for stabilization of open and/or unstable fractures where soft tissue injury precludes alternative treatments like IM rodding or casting. Used with Hoffmann® II Compact™ External Fixation System components and half/transfixing pins.

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.

This Special 510(k) submission is intended to address the introduction of a supplemental component to the predicate Hoffmann® II Compact External Fixation System. The subject device, named the Hoffmann® II Compact™ Baltimore Coupling, is a line extension of the Hoffmann® II Compact "Rod to Rod Coupling. The predicate Hoffmann® II Compact™ Rod Coupling is fabricated from stainless steel and aluminum. The subject Hoffmann® II Compact™ Baltimore Clamp is also fabricated from stainless steel and aluminum. The Hoffmann® II Compact™ Baltimore Coupling is a modification of the Hoffmann® II Compact" Rod to Rod Coupling. The modification involves a change to the rod to clamp interface which includes a change in profile, an added lip to provide resistance to rod slippage and chamfered edges to aid in rod insertion. Both the predicate Hoffmann® II Compact™ Rod to Rod Coupling and the subject Hoffmann® II Compact™ Baltimore Coupling will be made available to provide surgeons with a choice of couplings for use with the Hoffman® II Compact™ External Fixation System.

The subject Hoffmann® II Compact™ Baltimore Coupling has the same intended use and basic design concepts as the currently available Hoffmann® II Compact™ External Fixation System Rod to Rod Coupling. Mechanical testing demonstrated comparable mechanical properties to the predicate component.

Dear Ms. Kelly:

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. In addition, FDA may publish further announcements concerning your device in the Federal Register :

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
