## Intended Use

This submission describes an external fixation frame component when used together with the components of the Hoffmann® External Fixation System, Hoffmann® II External Fixation System and Monotube Triax " External Fixation System and in conjunction with Apex® Pins, creates an external fixation construct. External fixation frames provide stabilization of open and/or unstable fractures and where soft tissue injury precludes the use of other fracture treatments such as IM rodding or casting.

## Device Story

Hoffmann® 30 Degree Pelvic Double Ball Joint is an external fixation frame component; modification of Hoffmann® 5 Hole Ball Joint. Features lengthened clamp, additional ball joint, modified pin interface, and 30-degree tilt in pin-holding portion. Used in OR by surgeons to construct external fixation frames for bone stabilization. Integrates with Hoffmann®, Hoffmann® II, Monotube® TRIAX systems, and Apex® Pins. Provides mechanical support for fracture management; enables stabilization in complex anatomical scenarios where internal fixation is contraindicated due to soft tissue status.

## Clinical Evidence

Bench testing only.

## Technological Characteristics

Metallic bone fixation component. Design features: 30-degree angled pin-holding clamp, dual ball joint mechanism, and modified pin interface. Materials and sterilization methods are consistent with the predicate Hoffmann® 5 Hole Ball Joint system. Mechanical device; no software or energy source.

## 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.

## Predicate Devices

- Hoffmann® 5 Hole Ball Joint

Dear Ms. Ariemma:

Re:

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.
