Yes
The device is described as a replacement for the painful wrist joint due to various forms of arthritis, with the intent to alleviate pain, and restore functionality and mobility, which are therapeutic goals.
No
This device is an implantable total wrist arthroplasty system intended for the replacement of a painful wrist joint, not for diagnosing medical conditions.
No
The device description explicitly states it is a modular joint restoration system consisting of metallic and UHMWPE components, which are physical hardware implants.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to replace a painful wrist joint due to various types of arthritis. This is a surgical implant for treating a physical condition within the body.
- Device Description: The device is described as a modular joint restoration system consisting of metallic and UHMWPE components designed to replace the radiocarpal joint. This is a physical implant.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used in vitro (outside the body) to analyze samples. This device is an in vivo (within the body) implant.

Device Description
The Arthrosurface Total Wrist Arthroplasty (TWA) System is a modular joint restoration system that consists of both a radial implant assembly and carpal implant assembly. The radial implant assembly is comprised of a metallic stemmed tray component and Ultra-High-Molecular-Weight-Polyethylene (UHMWPE) articular component. The carpal implant assembly consists of a taper post component, a carpal plate, an articular component and two auxiliary bone screw components, all of which are metallic. The system is designed to replace the radiocarpal joint (distal radius and proximal row of carpal bones) and is intended to alleviate pain while restoring functionality and mobility of the joint.

§ 888.3800 Wrist joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A wrist joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a wrist joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have either a one-part radial component made of alloys, such as cobalt-chromium-molybdenum, with an ultra-high molecular weight polyethylene bearing surface, or a two-part radial component made of alloys and an ultra-high molecular weight polyethylene ball that is mounted on the radial component with a trunnion bearing. The metallic portion of the two-part radial component is inserted into the radius. These devices have a metacarpal component(s) made of alloys, such as cobalt-chromium-molybdenum. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

Dear Dawn Wilson:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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
