The summary describes a mechanical implant (hip insert) and its material properties and testing, with no mention of software, algorithms, or AI/ML capabilities.
Yes
The device is a component used in total hip arthroplasty, which is a surgical procedure to replace the hip joint. This procedure and the devices used within it are intended to treat conditions such as osteoarthritis, rheumatoid arthritis, and fractures to restore function and alleviate pain, thus providing therapeutic benefits.
No
Explanation: The device description clearly states it is an "MDM X3 Insert" for hip arthroplasty, and its intended use is for conditions like osteoarthritis and rheumatoid arthritis, and for revision procedures. This is a prosthetic implant meant for treatment, not for diagnosing a condition.
No
The device description clearly describes a physical implant (MDM X3 Insert) made of polyethylene, intended for use in total hip arthroplasty. It is a sterile, single-use device that articulates within a liner and is compatible with femoral heads. This is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device for surgical implantation in the hip joint to treat various conditions like osteoarthritis, rheumatoid arthritis, and fractures. This is a therapeutic and reconstructive purpose, not a diagnostic one.
- Device Description: The device is a physical implant (an MDM X3 Insert made of polyethylene) designed to articulate within a hip prosthesis. It is not a reagent, instrument, or system used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information.
- Testing: The performance studies focus on the mechanical properties, biocompatibility, sterilization, and wear characteristics of the implant, which are relevant to its function as a medical device for implantation, not for in vitro diagnosis.
In summary, the device described is a surgical implant used in total hip arthroplasty, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)

Dear Meenakshi Verma:
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 (the 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 available 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.
