The Medtronic Sofamor Danek CEMENT RESTRICTOR is intended for use as a cement restrictor in orthopaedic surgeries such as those involving the femoral canal and tibial plateau in hip stem and total knee replacement.
The Medtronic Sofamor Danek Cement Restrictor is NOT intended for any spinal indications.
The Medtronic Sofamor Danek CEMENT RESTRICTOR is a hollow, titanium and cylindrical frame with a tapered surface. The device is intended to be used in conjunction with standard PMMA cement.
The Medtronic Sofamor Danek CEMENT RESTRICTOR implants are manufactured from titanium alloy as described by ASTM F136 or ISO 5832-3.
The provided text is a 510(k) summary for the Medtronic Sofamor Danek CEMENT RESTRICTOR, which describes the device, its intended use, and its substantial equivalence to a previously cleared device. It also includes the FDA's clearance letter. However, this document does not contain specific information about acceptance criteria, device performance studies, sample sizes, expert ground truth establishment, or multi-reader multi-case studies.
The document primarily focuses on the regulatory clearance process for a modified geometry of an existing device, emphasizing its substantial equivalence to the predicate device (K003718). It states: "A Design Review for the modified device was provided in this submission." This suggests that the clearance relied on demonstrating that the new geometry did not alter the fundamental characteristics or performance that were deemed acceptable for the original device, rather than requiring a new, extensive performance study with acceptance criteria.
Therefore, I cannot provide the requested information from the given text. The text does not detail:
- Acceptance criteria or reported device performance metrics.
- Sample sizes for test sets, data provenance, or details on training sets.
- The number or qualifications of experts, or adjudication methods for establishing ground truth.
- Any multi-reader multi-case comparative effectiveness study or related effect sizes.
- Stand-alone algorithm performance (as this is a physical medical device, not an AI algorithm).
- The type of ground truth used for performance evaluation.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as sot forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification if the limitation statement above is added to your labeling, as described.
Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling.
