No
The document describes a traditional orthopedic implant system and its associated instrumentation, with no mention of AI or ML capabilities. The submission focuses on updating indications, labeling, and mechanical testing.
Yes
The device is indicated for the treatment of fractures and stabilization of bones, which are therapeutic actions.
No
The Gamma3 System is indicated for the treatment and stabilization of fractures and bone deformities, not for diagnosis. The device description and performance studies also focus on mechanical integrity and MR compatibility, which are relevant to a therapeutic device's safety and efficacy, not diagnostic capabilities.
No
The device description explicitly lists hardware components (Trochanteric Nails, Long Nails, Lag Screws, etc.) and the performance studies include mechanical testing and MR compatibility testing, which are relevant to physical implants.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for the "treatment of stable and unstable fractures as well as for stabilization of bones and correction of bone deformities in the intracapsular, trochanteric and shaft regions of the femur". This describes a surgical implant used directly on the patient's body.
- Device Description: The device components listed (Nails, Lag Screws, end caps, etc.) are all physical implants and surgical instruments.
- Lack of IVD Characteristics: An IVD is a medical device used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform any such tests on biological samples.
The information provided describes a surgical implant system used for orthopedic procedures, which falls under a different regulatory category than IVDs.

Dear Sanja Jahr:
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.

510(k) Summary
Description
The Gamma3 System consists of Trochanteric Nails, Long Nails, standard Lag Screws, U-Blade Lag Screws, end caps, set screws, distal locking screws, and instrumentation. The purpose of this traditional 510(k) is to update and consolidate system indications and intended use, update MR labeling to reflect new testing, update the mechanical testing analysis, and reference Ø5mm IMN Screws System Locking Screws as compatible components. Additional labeling changes were also made, including operative technique consolidation, safety information updates, and the addition of the MR Conditional symbol to package labels.

Gamma3 Trochanteric Nail:
The Gamma3 Trochanteric Nail is available in distal diameters ranging from 10 to 12mm and lengths of 170mm, 180mm, and 200mm. 170mm and 180mm nails have a single, oblong hole distally, while the 200mm nail has both an oblong hole and a round hole for distal fixation. The oblong hole allows for both static and dynamic locking configurations. All Trochanteric Nails are locked proximally with a Lag Screw or U-Blade Lag Screw. The set screw engages with the lag screw and allows translation while preventing rotation. End caps close off the nail and are available in 0mm, +5mm, and +10m lengths.
Nails, set screws, and end caps are available in titanium alloy (Ti-6Al-4V ELI) per ASTM F136 and stainless steel alloy per ASTM F1586. Stainless steel nails are offered in 11mm and 12mm diameters only. Titanium alloy implants have a type II anodized surface treatment.
Gamma3 Long Nail:
The Gamma3 Long Nail is available in lengths ranging from 240mm in both R1.5m and R2.0m antecurvatures. The proximal nail diameter is 15.5mm. Distal nail diameters include 10mm, l lmm, 13mm, and 15mm for R1.5m and 11mm, 13mm, and 15mm for R2.0. Distally, there is one round hole and one oblong hole, allowing both static and dynamic locking configurations. All Long Nails are locked proximally with a Lag Screw or U-Blade Lag Screws and end caps are identical to what's described for the Trochanteric nail. The Long Nail is available in titanium alloy (Ti-6Al-4V) per ASTM F136 and stainless steel alloy per ASTM F1586. The stainless steel long nail is only available in R2.0 and 11mm.
Lag Screw
Lag screws are cannulated with a major diameter of 10.5mm and lengths ranging from 70mm to 130mm. They are available in titanium alloy (Ti-6Al-4V ELI) per ASTM F136 and stainless steel alloy per ASTM F1586.
U-Blade Lag Screw
The U-Blade Lag Screw is used in combination with a U-Blade Lag Screw has a major diameter of 10.5mm. The U-Blade slides over the U-Blade Lag Screw, resulting in the spreading of the U-Blade at the tip of the screw to 12.5mm. The construct is fixated by the dedicated end cap. The U-Blade Lag Screw and U-Blade are offered in the same lengths as the standard lag screws. They are available in Ti-6Al-4V.
Distal Locking Screws
Distal locking screws are cannulated and fully threaded, with a diameter of 5.0mm and lengths ranging from 25mm to 120mm. They are available in titanium alloy (Ti-6AI-4V ELI) per ASTM F136 and stainless steel alloy per ASTM F1586.
Gamma3 Instrumentation:
Gamma3 instrumentation consists of class II (implant-specific) targeting devices which help facilitate insertion of the nails, lag screws, and distal locking screws. Targeting devices are manufactured from stainless steel per AISI 431 and carbon fiber reinforced PEEK. They were cleared under K123401. Other instrumentation includes drills, drill guides, k-wires, and screw drivers.
