Device Description

AI/ML Overview

This document is a 510(k) premarket notification for the "Reduced Size Oncology Salvage System" by Biomet Orthopedics, Inc. It establishes substantial equivalence to a predicate device but does not contain information about the acceptance criteria or a study proving the device meets those criteria.

Therefore, I cannot provide the requested information based solely on the provided text. The document is a regulatory approval, not a performance study report.

Here's what I can extract/infer from the document regarding the device and its regulatory status:

Device Name: Reduced Size Oncology Salvage System
Applicant/Sponsor: Biomet Orthopedics, Inc.
Legal Marketed Device to which Substantial Equivalence is Claimed (Predicate Device): Oncology Salvage System, K002757, Biomet, Inc.
Indications for Use:
- Treatment in small adults and children requiring proximal femoral, distal femoral, total femur, or proximal tibial replacements.
- Resurfacing components for the proximal tibia and distal femur.
- Painful and disabled joint resulting from avascular necrosis, osteoarthritis, rheumatoid arthritis, or traumatic arthritis.
- Correction of varus, valgus, or post-traumatic deformity.
- Correction or revision of unsuccessful osteotomy, arthrodesis, or previous joint replacement.
- Ligament deficiencies.
- Tumor resections.
- Treatment of non-unions, femoral neck and trochanteric fracture of the proximal femur with head involvement, unmanageable using other techniques.
- Revision of previously failed total joint arthroplasty.
- Trauma.
Usage: For cemented use only.
Regulatory Classification: Class II device, Product Code: KRO, Regulation Name: Knee joint femorotibial metal/polymer constrained cemented prosthesis (21 CFR 888.3510).
Regulatory Action: FDA found the device substantially equivalent to a legally marketed predicate device.

Missing Information:

The provided text does not contain any information regarding:

A table of acceptance criteria and reported device performance.
Sample sizes used for a test set, nor data provenance.
Number of experts used to establish ground truth or their qualifications.
Adjudication method.
Multi-reader multi-case (MRMC) comparative effectiveness study, or any effect size for human reader improvement.
Standalone performance study (algorithm only without human-in-the-loop).
Type of ground truth used (e.g., expert consensus, pathology, outcomes data).
Sample size for the training set.
How ground truth for the training set was established.

This document serves as an FDA clearance letter based on substantial equivalence to an existing device, implying that the safety and effectiveness were demonstrated by comparison to the predicate, rather than through new, independent clinical performance studies detailed in this specific document. Such information would typically be in a separate clinical study report or a more detailed submission accessible during the 510(k) review process, but not typically summarized in the public-facing "Summary of Safety and Effectiveness" or the FDA clearance letter itself.

Dear Ms. Shultz:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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 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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Regulation Number and Section

§ 888.3510 Knee joint femorotibial metal/polymer constrained cemented prosthesis.

(a)
Identification. A knee joint femorotibial metal/polymer constrained cemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits translation or rotation in one or more planes and has components that are linked together or affined. This generic type of device includes prostheses composed of a ball-and-socket joint located between a stemmed femoral and a stemmed tibial component and a runner and track joint between each pair of femoral and tibial condyles. The ball-and-socket joint is composed of a ball at the head of a column rising from the stemmed tibial component. The ball, the column, the tibial plateau, and the stem for fixation of the tibial component are made of an alloy, such as cobalt-chromium-molybdenum. The ball of the tibial component is held within the socket of the femoral component by the femoral component's flat outer surface. The flat outer surface of the tibial component abuts both a reciprocal flat surface within the cavity of the femoral component and flanges on the femoral component designed to prevent distal displacement. The stem of the femoral component is made of an alloy, such as cobalt-chromium-molybdenum, but the socket of the component is made of ultra-high molecular weight polyethylene. The femoral component has metallic runners which align with the ultra-high molecular weight polyethylene tracks that press-fit into the metallic tibial component. The generic class also includes devices whose upper and lower components are linked with a solid bolt passing through a journal bearing of greater radius, permitting some rotation in the transverse plane, a minimal arc of abduction/adduction. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
