The device description and intended use focus solely on the physical characteristics and surgical application of a hip stem implant. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes.
The device is a hip stem used for hip replacement, which is a medical procedure to treat painful and disabling joint diseases. It is explicitly indicated for therapeutic purposes such as treating fractures, necrosis, and arthritis of the hip.
No
Explanation: The document describes a hip stem, which is an implant used in hip replacement surgeries. It is a therapeutic device designed to replace or support a damaged or diseased hip, not to diagnose a condition.
No
The device description clearly indicates that the device is a physical hip stem, which is a hardware component. The modification involves introducing new sizes and reducing the length of the stem.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections.
- Device Description and Intended Use: The description and intended use clearly indicate that this device is a femoral component for hip replacement surgery. It is an implantable medical device used to replace or augment the hip joint.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory tests.
Therefore, the Howmedica Osteonics® Restoration™ HA Stems are a surgical implant, not an in vitro diagnostic device.

Intended Use / Indications for Use
The Restoration™ HA Hip Stems are single use components. They are intended for cementless fixation within the prepared femoral canals of patients requiring hip arthroplasty. The modified and predicate hip stems are intended to be used in conjunction with any commercially available Howmedica Osteonics C-Taper femoral bearing head. For use as a total hip replacement, the modified and predicate stems may be used in conjunction with any legally marketed Howmedica Osteonics acetabular component. The Restoration™ HA Hip Stems are manufactured from titanium allov (ASTMF-620-97). The indications for the Restoration™ HA Hip Stems include the following:
For Use as a Bipolar Hip Replacement:
- · Femoral head/neck fractures or non-unions.
- · Aseptic necrosis of the femoral head.
- · Osteo-, rheumatoid, and post-traumatic arthritis of the hip with minimal acetabular involvement or distortion.
Other Considerations:
- · Pathological conditions or age considerations which indicate a more conservative acetabular procedure and an avoidance of the use of bone cement in the acetabulum.
- . Salvage of failed total hip arthroplasty.
For Use as a Total Hip Replacement:
- Painful, disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid . arthritis, post-traumatic arthritis or late stage avascular necrosis.
- Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other . procedure.
- Clinical management problems where arthrodesis or alternative reconstructive techniques are . less likely to achieve satisfactory results.
Additional Indication for Howmedica Osteonics Head/Neck Stems:
- · Clinical circumstances which require an altered femoral resection level due to a proximal fracture, bone loss, or calcar lysis.

Device Description
The Osteonics® Restoration™ HA Hip Stems are currently marketed devices that are being modified (and titled Howmedica Osteonics® Restoration™ HA Hip Stems). The modification involves introducing two new stem sizes, size 5 and size 6, each with two distal diameters, 9mm and 11mm for the size 5, and 10mm and 12mm for the size 6. Additionally, the stem length will be reduced by 10mm (from 155mm to 145mm) for 6512-xxxx and by 30mm (from 205mm to 175mm) for 6513-xxxx. All other aspects of the Restoration™ HA Hip Stems will remain unchanged.

§ 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 Ms. Dillon:
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 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 (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.
