Intended Use
The LINK ® MP® Monoblock is indicated for patients with Mobility-limiting diseases, fractures or defects of the hip joint or proximal femur which cannot be treated by conservative or osteosynthetic procedures The LINK® MP® Monoblock is indicated for the following conditions: - Revision of loosened femoral prosthesis components involving extensive bone resorption of the proximal femur and widening of the medullary cavity or marked thinning of proximal femoral cortical bone the fixation of a new standard prosthesis is not possible - Revision of loosened femoral prosthesis components by peri-/subprosthetic fracture The device is intended for cementless use.
Device Description
The LINK® MP® Monoblock Hip Prosthesis is a straight hip prosthesis stem. The hip prosthesis is made of Titanium Aluminum Vanadium alloy (Ti-6Al-4V). The prosthesis stems are available in a range of sizes, lengths, CCD angles and offsets. Additional features include a tapered stem with a microporous glass-blasted surface. The LINK® MP® Monoblock Hip Prosthesis is designed to be used in conjunction with femoral heads that are manufactured from Cobalt Chromium Molybdenum casting alloy (CoCrMo) or ceramic (BIOLOX® forte and BIOLOX® delta) via 12/14 morse taper (K161840). In total joint use, the femoral head articulates aqainst LINK® BiMobile Cup System (K171273). The LINK® MP® Monoblock Hip Prosthesis provides cementless fixation to the bone.
More Information

No
The summary describes a mechanical hip prosthesis and does not mention any software, algorithms, or data processing that would indicate the use of AI/ML.

Yes
The device is a hip prosthesis, which is used to treat mobility-limiting diseases, fractures, or defects of the hip joint or proximal femur. This indicates its use in restoring or improving physical function, which is a therapeutic purpose.

No

This device is a hip prosthesis, intended for surgical implantation to treat orthopedic conditions, not to diagnose them.

No

The device description clearly states it is a "straight hip prosthesis stem" made of Titanium Aluminum Vanadium alloy, which is a physical implant, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Device Description and Intended Use: The LINK® MP® Monoblock is a hip prosthesis stem. Its intended use is to replace or revise a damaged hip joint or proximal femur through surgical implantation. It is a physical implant used within the body, not a device used to test samples outside the body.
  • Lack of IVD Characteristics: The description does not mention any testing of biological samples, analysis of biomarkers, or any other activities typically associated with IVDs.

Therefore, the LINK® MP® Monoblock is a surgical implant, 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)
Classification. Class II.

Dear Andre Malotki:

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 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for
