The document describes a physical implant (femoral stem) and its materials, indications, and predicate devices. There is no mention of software, algorithms, or any technology related to AI or ML.
Yes
This device is a hip implant used to treat various non-inflammatory degenerative joint diseases and fractures, which falls under the definition of a therapeutic device.
No
The device, the Citation TMZF HA Stem, is an implantable medical device for hip surgery, not a tool used to diagnose conditions.
No
The device description clearly describes a physical implant (femoral stem) made of TMZF Alloy with coatings, intended for surgical implantation. It is not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for replacing or reconstructing the femoral joint. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details a physical implant (a femoral stem) made of specific materials and coatings, designed to be surgically inserted into the body. This is consistent with a medical device, not a diagnostic test.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing information for diagnosis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
N/A
Intended Use / Indications for Use
The Citation TMZF HA Stems are anatomic stems in a variety of lengths and distal diameters. The larger diameter stems have a rotated distal slot that contains distal flutes or grooves.
This stem is intended for the reconstruction of the head and neck of the femoral joint. The device is intended for primary reconstruction of the proximal femur or revision of a previous total hip arthroplasty. The stems can be used with any currently available Howmedica Osteonics acetabular components and V40 Femoral Heads that can be mated with a 5° 40' BG taper.
The Citation TMZF HA Stem is indicated for cementless primary hip surgery in cases of non-inflammatory degenerative joint disease including osteoarthritis, avascular necrosis, rheumatoid arthritis, and correction of functional deformity. Additionally it can be used in treatment of nonunion, and femoral neck and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques. It is also indicated for use in revision procedures where other treatments or devices have failed.

§ 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.

510(k) Summary
Device: Citation TMZF HA Stem
The Citation TMZF HA Stems are anatomic stems in a variety of lengths and distal diameters. The larger diameter stems have a rotated distal slot that contains distal flutes or grooves.
This stem is intended for the reconstruction of the head and neck of the femoral joint. The device is intended for primary reconstruction of the proximal femur or revision of a previous total hip arthroplasty. The stems can be used with any currently available Howmedica Osteonics acetabular components and V40 Femoral Heads that can be mated with a 5° 40' BG taper.
The Citation TMZF HA Stems will be fabricated from TMZF Alloy. The stems are coated with a CP Titanium plasma spray coating and Pure-Fix™ HA.
The substantial equivalence of the Citation TMZF HA Stems is based upon equivalence in intended use, materials, design, and operational principles to Meridian® Titanium Femoral Stem (K972228); the Howmedica® Asymmetric Stem Femoral Component (K955871); and the Osteonics® Omnifit® AD-HA Hip Stem Series (K941366).
Testing indicates that the addition of the HA coating over plasma spray has no effect on the stem fatigue strength.

Dear Ms. Daudelin:
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.
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.
