Intended Use

The AXI+LINE™ Proximal Bunion Correction System is indicated for fixation of fractures, osteotomies, non-unions and fusions of small bones and small bone segments in the foot and ankle.

Device Story

AXI+LINE™ Proximal Bunion Correction System is a metallic bone fixation plate system. Input: surgical site requiring bone fixation. Device consists of modified semi-tubular titanium alloy plates with specific correction angles between proximal and distal segments, plus non-locking cortical and locking titanium screws. Used by surgeons in clinical settings for foot and ankle procedures. Operates as a mechanical fixation device to stabilize bone segments during healing. Benefits patient by providing structural support for osteotomies or fractures. Output: physical stabilization of bone segments. Procedure includes surgical site preparation and insertion using provided instruments.

Clinical Evidence

Bench testing only. No clinical data provided. Performance validated via Finite Element Analysis (FEA) and mechanical testing per ASTM F-382 (static/dynamic 4-point bend) and ASTM F-543 (axial push-out, insertion torque, torque to failure). Biocompatibility established via predicate device material history (ASTM F136 titanium alloy).

Technological Characteristics

Materials: Titanium alloy (ASTM F136). Components: Modified semi-tubular bone plates, locking and non-locking cortical screws. Mechanical testing: ASTM F-382 (plates), ASTM F-543 (screws). Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for fixation of fractures, osteotomies, non-unions, and fusions of small bones and small bone segments in the foot and ankle.

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. Schlotterback:

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. 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.

| Classification: | According to Section 13 of the Federal Food, Drug and<br>Cosmetic Act, the device classification is Class II,<br>Performance Standards. |
| Predicate Devices: | K131061 – Nextremity Solutions – Restore™ Bunion<br>Correction System<br>K140724 – Nextremity Solutions – MSP™ Metatarsal<br>Shortening System<br>K143365 - Empirical Testing Corp.- Eminent Foot Plate<br>System<br>K142581 - PaxMed International LLC – APTUS Foot<br>System |
| | The Nextremity Solutions AXI+LINE™ Proximal Bunion<br>Correction System possesses the same technological<br>characteristics as the predicate devices. These characteristics<br>include the intended use, basic design, material, size and<br>fundamental technology. |
| Device Description: | The AXI+LINE™ Proximal Bunion Correction System is a<br>plate system made from Titanium alloy. The geometry of<br>the plate is that of a modified semi-tubular bone plate with a<br>correction angle between the proximal and distal plate<br>segments. The system also includes non-locking cortical<br>and locking screws also made from Titanium alloy and<br>necessary surgical site preparation and insertion instruments<br>as a procedure pack. |
| Indications for Use: | The Nextremity Solutions AXI+LINE™ Proximal Bunion<br>Correction System is indicated for fixation of fractures,<br>osteotomies, non-unions and fusions of small bones and<br>small bone segments in the foot and ankle. |
| Safety and Performance: | Finite Element Analysis was used to determine the worst-<br>case plate configuration for the static and dynamic four-<br>point bend testing. |
| | Mechanical testing was performed as described in relevant<br>recognized standards, including static and dynamic 4 point<br>bend testing of the AXI+LINE™ Proximal Bunion<br>Correction System plate per ASTM F-382 and axial push-<br>out, insertion torque, and torque to failure testing of the<br>locking and non-locking bone screws per ASTM F-543. |
| | The product is made from the same material as the predicate<br>Nextremity MSP Metatarsal Shortening System. The device<br>components are comprised of standard medical Titanium<br>alloy (ASTM F136) with a long history of successful use for<br>the same and other orthopedic indications. Biocompatibility<br>testing was, therefore, not performed in support of the<br>proposed device. |
| Conclusion: | Based on comparisons of the indications for use,<br>technological characteristics, and the results of performance<br>testing described above, the AXI+LINE™ Proximal Bunion<br>Correction System has been shown to be substantially |
