Intended Use

The DynaNail Mini and DynaNail Hybrid System are indicated for fracture fixation, osteotomies, reconstruction procedures, non-unions, and fusions of short bones, long bones, small fragments or large fragments in the foot and ankle. The DynaNail Helix is indicated for use in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair, and fracture fixation of bones appropriate for the size of the device such as short bones, long bones, and small or large fragments in the foot and ankle. The DynaClip, DynaClip Forte, DynaClip Delta, DynaClip Quattro Bone Staples are indicated for • Fracture, osteotomy fixation and joint arthrodesis of the hand and foot. • Fixation of proximal tibial metaphysis osteotomy. • Fixation of small fragments of bone (i.e. small fragments of bone which are not comminuted to the extent to preclude staple placement). These fragments may be located in long bones such as the femur, fibula, and tibia in the lower extremities; the humerus, ulna, or radius in the upper extremities; the clavicle and ribs; and in flat bones such as the pelvis, scapula, and sternum.

Device Story

DynaNail and DynaClip systems are orthopedic fixation devices; used for bone reconstruction, fracture repair, and joint fusion. DynaNail Mini/Hybrid/Helix are nails/fasteners; DynaClip are bone staples. Devices are implanted by surgeons in clinical settings to provide internal bone fixation. Operation involves mechanical stabilization of bone segments to facilitate healing. This submission updates labeling to include 'MR Conditional' status. No changes to device design, materials, or fundamental scientific technology. Benefit is stable bone fixation during healing process.

Clinical Evidence

No clinical data provided. Evidence consists of non-clinical bench testing to support MR Conditional labeling, specifically testing per ASTM F2052, ASTM F2213, ASTM F2182, and ASTM F2119.

Technological Characteristics

Materials: Nitinol (nickel titanium alloy) and titanium alloy (Ti6Al-4V ELI). Components include fusion nails, end caps, screws, washers, and bone staples. MR testing performed per ASTM F2052, F2213, F2182, and F2119. Devices are sterile, implantable orthopedic fixation hardware.

Indications for Use

Indicated for fracture fixation, osteotomies, reconstruction, non-unions, and fusions of short/long bones and fragments in the foot and ankle (DynaNail family); and for fracture/osteotomy fixation and joint arthrodesis of the hand and foot, proximal tibial metaphysis osteotomy, and fixation of small non-comminuted bone fragments in long, flat, and extremity bones (DynaClip family).

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.

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 available 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.

Substantial Equivalence: The proposed devices are substantially equivalent in intended use and fundamental scientific technology to their respective predicate devices listed below: | Predicate Device | Manufacturer | 510K # | Date Cleared | | --- | --- | --- | --- | | DynaNail Mini (Primary Predicate) | MedShape, Inc. | K182677 | 02/14/2019 | | DynaNail Hybrid | MedShape, Inc. | K203381, K240530 | 01/15/2021 03/21/2024 | | DynaNail Helix | MedShape, Inc. | K203595 | 01/04/2022 | | DynaClip | MedShape, Inc. | K181781 | 11/05/2018 | | DynaClip Forte | MedShape, Inc. | K193305 | 04/23/2020 | | DynaClip Delta and Quattro | MedShape, Inc. | K220812 | 08/19/2022 | DynaNail TTC Fusion System (K250628) was used as a reference device in this submission. H. Basis for Submission: This Traditional 510(k) submission serves as notification to the agency of an update to the product labeling for the DynaNail Device Family and DynaClip Device Family to include an 'MR Conditional' Magnetic Resonance (MR) Environment claim. I. Technological Characteristics: The proposed devices maintain the same technological and performance characteristics and have the same fundamental design and intended use as their respective predicate devices. The addition of an MR Conditional statement to the DynaNail Device Family and DynaClip Device Family labeling do not raise new questions regarding safety or effectiveness. J. Summary of Testing Non-clinical testing was conducted to determine the MR environment, which concluded that "MR Conditional" will be added to labeling. - MR Testing per ASTM F2052, ASTM F2213, ASTM F2182, ASTM F2119 Evaluation of the biocompatibility, sterility, shelf life, packaging, and mechanical performance of the proposed devices leveraged identical manufacturing materials and processes, sterilization methods, and packaging to the predicate devices. K. Conclusion: Based on the results of the MR testing, as well as a comparison of device design and intended use, the proposed DynaNail Mini, DynaNail Hybrid, DynaNail Helix and DynaClip, DynaClip Forte, DynaClip Delta and DynaClip Quattro Bone Staples are determined to be substantially equivalent to their respective predicate device. The same and equivalent design, materials, intended use, and performance characteristics, as well as the results of non-clinical testing, support the conclusion that the proposed device does not raise new questions of safety or effectiveness.
