No
The Precision Screw is a physical device used as a reference point during stereotactic surgery. It does not perform any diagnostic functions that involve analyzing data or providing information about a patient's medical condition.
No
The device description explicitly states it is a "self-drilling metallic fixation device," which is a hardware component, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Precision Screw Function: The Precision Screw is a physical device implanted into the patient's bone to serve as a reference point during surgery. It does not analyze or test any biological samples.
The description clearly states its purpose is for establishing fixed reference points in patients undergoing Stereotactic Surgery. This is a surgical tool, not a diagnostic test performed on a sample.

Intended Use / Indications for Use
The Precision Screw is intended for establishing fixed reference point(s) in patients undergoing Stereotactic Surgery for procedures in the cortical bone of the vertebrae. The Precision Screw can be used as an accessory with frameless navigation systems.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
- Biocompatibility testing: The biocompatibility evaluation for the Precision Screw was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing, " May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The Precision Screw is considered as permanent implants. The titanium material conforms to ASTM F136 for chemical composition and is suitable for surgical implant applications.
- Mechanical strength and integrity testing: The mechanical testing performed on the Precision Screw demonstrates that it meets the performance standards identified in ASTM F543-13 and ISO 6475:1989, for determining the torsional properties and driving torque of the Precision Screw.
- Visual Acuity using a suitable frameless navigationsystem: The visibility of the Precision Screw on O-Arm images and the suitability for its use for spinal navigation was assessed by inserting Precision Screws into a Spinal Bone Model developed specifically for this tests performed on these screws serve to confirm that the screws are highly visible and fit for the purpose they are intended for in the operative setting.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE .6
The Precision screw has similar characteristics to the Lorenz predicate. Notable differences are that the Precision screw is delivered sterile and is specified for vertebral use. However, these differences have been shown to not impact the safety and effectiveness of the Precision screw:
- Sterilization has been validated
- Viable anatomic locations on the vertebrae were evaluated for safety and identified in the labeling. ●
Since most features are equivalent and new features do not add risk, the Precision screw system is equivalent to the predicate.
1.7 PERFORMANCE DATA
Since the predicate device was cleared based in part on the results of clinical studies, and since the comparison of bench testing to clinical outcomes is well understood for this type of device, clinical testing was not required to support substantial equivalence. The non-clinical data provided supports the safety of the device and its technological equivalence to the predicate device.
The following performance data were provided in support of the substantial equivalence determination.
- Biocompatibility testing
The biocompatibility evaluation for the Precision Screw was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing, " May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The Precision Screw is considered as permanent implants. The titanium material conforms to ASTM F136 for chemical composition and is suitable for surgical implant applications.
- Mechanical strength and integrity testing
The mechanical testing performed on the Precision Screw demonstrates that it meets the performance standards identified in ASTM F543-13 and ISO 6475:1989, for determining the torsional properties and driving torque of the Precision Screw.

1.8 SUMMARY
The Precision Screw is substantially equivalent to the Lorenz Fiducial Screw both in terms of its intended use, design and the fundamental scientific technology. The Precision Screw was found to have a safety and effectiveness profile that is similar to the predicate device. The Lorenz Fiducial Screw was cleared by FDA in K010427.
1.9 CONCLUSIONS
The Precision Screw is substantially equivalent to the predicate device (Lorenz Fiducial Screw K010427).
