Device Story

MAVERICK External Fixation System provides temporary bone stabilization; used for long bones, feet, and pelvis fractures; also for bony/soft tissue deformities. System comprises stainless steel bone pins, composite bars, and titanium clamps; components assembled into custom frames by surgeons in clinical settings. Principle of operation involves clamping pins to external frame to stabilize bone segments. Output is a rigid mechanical construct; assists in fracture healing or deformity correction. Benefits include temporary stabilization of skeletal structures.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included axial and torsional grip strength for clamps, bars, and pins; pin insertion/pullout force; resistance to slip; and cyclic/load-to-failure testing of full pelvic and joint-spanning frames. Biocompatibility assessment and MRI justification provided.

Technological Characteristics

External fixation system consisting of stainless steel bone pins, composite bars, and titanium clamps. Operates via mechanical stabilization of bones through fixation pins clamped to an external frame. Components are modular for frame assembly. No software or energy source.

Indications for Use

Indicated for temporary stabilization of long bones, feet, and pelvis in patients requiring open or closed fracture fixation or correction of bony/soft tissue deformities.

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.

# Dear Brad Sheals:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. 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. 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

## Indications for Use

The MAVERICK External Fixation System is intended to be used for temporary stabilization of the long bones, feet, and pelvis.

The indications for the Smith & Nephew MAVERICK External Fixation System are the following:

- Open and closed fracture fixation .
- Bony or soft tissue deformities

#### Technological Characteristics

The principle of operation for the subject and the predicate devices is stabilization of bones through fixation with pins clamped to an external fixation frame built with composite bars. The MAVERICK External Fixation System is similar to legally marketed predicate devices in that they are manufactured from similar materials, are of structurally similar size, strength and stiffness, and incorporate similar methods of assembly and adjustment.

#### Performance Testing

To further support a determination of substantial equivalence, Mechanical testing and/or assessments were utilized. A review of the data indicates that the subject MAVERICK External Fixation System is substantially equivalent to one or more of the previously cleared predicate devices listed above. The following overall bench performance strategy was used as a basis for the determination of substantial equivalence.

| Device Testing | |

| Subject Clamps/Post Testing | Axial Grip Strength of Clamps<br>Torsional Grip Strength of Clamps |
| Testing of Interconnections in Full Constructs | Cyclic Testing of Pelvic Frames<br>Cyclic Testing of Joint Spanning Style<br>Frames |
| Rigidity Testing to Failure of Full Constructs | Load to Failure of Pelvic Frames<br>Load to Failure of Joint Spanning Style<br>Frames |

## Overall Bench Performance Testing Strategy

A biocompatibility assessment was completed. A MRI justification was utilized in lieu of testing.

#### Conclusion

Based on similarities to the predicate multi-lateral external fixation systems and a review of testing performed, the subject MAVERICK External Fixation System is substantially equivalent to the commercially available predicate devices.
