No
The device description and performance studies focus solely on the mechanical properties and biological compatibility of the screws and associated instrumentation. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is a medical screw intended for bone fixation, specifically in the treatment of fractures and other bone conditions, which directly contributes to healing and restoring function, hence performing a therapeutic role.
No
The device description clearly states it is a system of "headless cannulated screws intended for bone fixation in the treatment of fractures, non-unions, osteotomies, or to aid in small joint fusions." This indicates a therapeutic, rather than diagnostic, function.
No
The device description clearly states it is comprised of physical screws and associated instrumentation, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the treatment of fractures, osteotomies, and nonunions of small bones. This is a therapeutic purpose, not a diagnostic one.
- Device Description: The device is a surgical implant (screws) used for bone fixation. It is a physical device implanted in the body, not a reagent, instrument, or system used to examine specimens from the human body.
- Lack of Diagnostic Activity: There is no mention of the device being used to analyze samples (blood, tissue, etc.) or provide information about a patient's health status through in vitro testing.
IVD devices are specifically designed to perform tests on samples taken from the human body to diagnose diseases or conditions. This device is used within the human body for structural support and healing.

Device Description
The KLS Martin Cannulated Headless Screws (CHS) system is comprised of headless cannulated screws intended for bone fixation in the treatment of fractures, non-unions, osteotomies, or to aid in small joint fusions of the hand, wrist, foot, and ankle. Bone fixation is achieved by proximal and distal threads designed with different pitches that, when inserted into the bone, cause compression of the bone fragments for bone reduction, stability, and healing. Cannulation of the screws is designed to allow the user to insert the screw over the guide wire for proper placement prior to compression. The CHS system offers screws in various diameters, overall lengths, and thread lengths to accommodate different sizes and types of bone reduction, such as scaphoid fractures and non-unions. The screws are self-drilling and self-tapping to eliminate the need for drilling a pilot hole prior to implantation. All screws are manufactured from Ti-6Al-4V (ASTM F136:2013). This system also includes the necessary and appropriate instrumentation to facilitate implantation of the screws by qualified and trained physicians.

Summary of Performance Studies
Mechanical Properties Testing: The mechanical properties of the KLS Martin Cannulated Headless Screws were tested in accordance with ASTM F543-13:2013 Standard Specification and Test Methods for Metallic Medical Bone Screws. The torsional properties, driving torque, and axial pullout strength were tested on the various screw lengths and thread diameters, in which tests were successfully completed without any signs of device failure. Comparative testing of the KLS Martin 3.0 mm cannulated screw to the Synthes 3.0 mm cannulated screw demonstrates substantial equivalence in performance testing.
Pyrogenicity Testing: LAL endotoxin testing was conducted according to AAMI ANSI ST72 on the subject device screws to address the presence of bacterial endotoxins and ensure they meet pyrogen limit specifications. The results of the testing demonstrate that the KLS Martin Cannulated Headless Screws contain endotoxin levels below the USP allowed limit for medical devices and meet pyrogen limit specifications.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
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.(b)

Indications for Use:
KLS Martin Cannulated Headless Screws are intended for the treatment of fractures, osteotomies, arthrodeses, and non-unions of small bones in the hand, wrist, foot, and ankle.
Technological Characteristics/Substantial Equivalence Discussion:
Similarities to Predicate Devices
The subject and predicate devices include cannulated headless screws with the same intended use. All screw systems are available in titanium alloy, are implanted using the same methods of fixation, and are offered in sterile packaging. The subject and predicate devices provide headless, cannulated, self-tapping screws that have threaded heads which are inserted over the guide wire and countersunk into the bone for compression of bone segments and are available in short and long thread lengths. The subject device is identical in screw length to the predicate devices, with the exception of the Tiger Headless Cannulated Screws (K112737).
Differences to Predicate Devices
The subject device differs from the Synthes 3.0 Headless Compression predicate device in that it is only provided in titanium alloy. The Synthes 3.0 Headless Compression screws are provided in both titanium alloy and stainless steel. The fact that the subject device will not be provided in stainless steel does not have any impact on the safety and effectiveness of the device. Both devices are manufactured from titanium alloy, which is a well-known material used in bone fixation devices.
In addition, the subject device manufactures screws with thread diameters of 2.5 mm and 3.0 mm, while the Synthes predicate device manufactures screws with a thread diameter of only 3.0 mm, and the Tiger predicate device manufactures screws with thread diameters of 2.0 mm and 2.4 mm, in addition to the 3.0 mm. The difference in availability of one thread diameter versus another in comparison to the predicate devices does not impact the safety and effectiveness of the subject device. The subject device provides thread diameters that are identical to the Synthes screw and falls within the primary predicate device (Tiger Headless Cannulated Screws) thread diameter range, which is between 2.0 and 3.0 mm.
Supplementary, another difference between the subject device and the predicate devices is the subject device has a screw length ranging from 10-40 mm, whereas the primary predicate has a screw length ranging only from 10-34 mm. This difference in screw length range has no impact on the safety and effectiveness of the subject device. Having a larger screw length range allows for more availability in different types of bone fixation where a longer screw might be needed for sufficient reduction.

Non-clinical Performance Data:
Mechanical Properties Testing
The mechanical properties of the KLS Martin Cannulated Headless Screws were tested in accordance with ASTM F543-13:2013 Standard Specification and Test Methods for Metallic Medical Bone Screws. The torsional properties, driving torque, and axial pullout strength were tested on the various screw lengths and thread diameters, in which tests were successfully completed without any signs of device failure. Comparative testing of the KLS Martin 3.0 mm cannulated screw to the Synthes 3.0 mm cannulated screw demonstrates substantial equivalence in performance testing.
Pyrogenicity Testing
LAL endotoxin testing was conducted according to AAMI ANSI ST72 on the subject device screws to address the presence of bacterial endotoxins and ensure they meet pyrogen limit specifications. The results of the testing demonstrate that the KLS Martin Cannulated Headless Screws contain endotoxin levels below the USP allowed limit for medical devices and meet pyrogen limit specifications.
Clinical Performance Data:
Clinical testing was not necessary for the determination of substantial equivalence.
Conclusion:
The KLS Martin Cannulated Headless Screws have the same intended use, same principles of operation, similar technological features, and similar performance testing compared to the predicate devices. The information presented supports substantial equivalence of the KLS Martin Cannulated Headless Screws to the predicate devices.
