The device description focuses on the mechanical design and materials of a hip stem and screws, with no mention of AI or ML capabilities.
No
A therapeutic device is used to treat a disease or condition. This device is an implantable hip stem used to replace bone, not to treat a disease.
No
The device description indicates that the Interlocking Hip Stems are metallic femoral stems used as a component in hip replacement surgery, and the intended use describes their application in cases of revision, trauma, fracture, oncology, or other situations where severe proximal bone loss may compromise the fixation and stability of a standard hip replacement prosthesis. This product is a therapeutic medical device, not a diagnostic one.
No
The device description clearly details physical, metallic implants (femoral stems and cross-screws) made from titanium alloy. It does not describe 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 surgical implant for replacing a portion of the femur in hip replacement procedures. This is a therapeutic device used in vivo (within the body).
- Device Description: The description details a metallic femoral stem and screws, which are physical implants.
- Lack of IVD characteristics: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a patient's health.
IVD devices are used to perform tests on samples taken from the body to diagnose, monitor, or screen for diseases or conditions. This device is a surgical implant used to treat a physical condition.

Intended Use / Indications for Use
Interlocking hip stems are indicated for non-cemented application in cases of revision, trauma, fracture, oncology or other situations where severe proximal bone loss may compromise the fixation and stability of a standard type hip replacement prosthesis.

Device Description
The Interlocking Hip Stems are metallic femoral stems with transverse screw holes in the distal portion. These devices offer a combination of total hip replacement with the benefits of an intramedullary nail. Each stem has three medial/lateral slots.
Two styles of stems are available. The first geometry is that of a Mallory/Head Calcar device. This device provides head/neck replacement to compensate for bone deficiencies in the proximal/medial portion of the femur. The second style of stem is that of Biomet's Bi-Metric device. This device has a bi-planner taper which promotes increased proximal off-loading and filling of the metaphysis. The device has a collar.
The cross-screws are available in lengths of 25mm to 60mm and 5mm diameters. Only the end of the screw is threaded so that the portion of the screw that resides inside the stem is smooth.
The femoral stems are manufactured from titanium alloy (Ti-6A1-4V) conforming to ASTM F-620. The cross-screws are manufactured from Ti-6Al-4V conforming to ASTM F-136.

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.
(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)

Dear Ms. Beres:
We have reviewed your Section 510(k) 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). You may, therefore, market the device, subject to the general control provisions of the Act. The general control 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 (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 requirement, as set 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.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
