Device Description

Navigated Spine Instruments are nonsterile, reusable surgical instruments (screw inserters and taps) intended to be used when implanting previously cleared components of Mesa, Everest, Yukon, Xia 3, Xia 4.5, and ES2. These instruments are intended to be used with the Stryker Spine Navigation System.

AI/ML Overview

The provided text describes the regulatory clearance for "Navigated Spine Instruments" by Stryker Spine but does not contain the detailed acceptance criteria or the specific study that proves the device meets those criteria.

The "Summary of the Performance Data" section generically states: "Performance testing was conducted to ensure that the Navigated Spine Instruments are acceptable for their intended use, to ensure functionality and compatibility with the Stryker Spine Navigation System using the Rotational Navigation Adapter and associated trackers, and to demonstrate substantial equivalence to the predicate device. The performance of Navigated Spine Instruments has met all acceptance criteria."

This statement confirms that performance testing was done and acceptance criteria were met, but it does not provide the specifics of:

  1. A table of acceptance criteria and the reported device performance
  2. Sample size used for the test set and the data provenance
  3. Number of experts used to establish the ground truth for the test set and their qualifications
  4. Adjudication method for the test set
  5. If a multi reader multi case (MRMC) comparative effectiveness study was done, or its effect size
  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
  7. The type of ground truth used
  8. The sample size for the training set
  9. How the ground truth for the training set was established

Therefore, based solely on the provided text, I cannot complete the request. The document describes the device, its intended use, and its equivalence to predicate devices, but it does not delve into the specifics of the performance study's methodology or detailed results.
