The summary describes a mechanical implant (femoral stem) and its associated components and testing. There is no mention of software, algorithms, image processing, or any terms related to AI/ML.
Yes
The device is a femoral stem intended for hip replacement, which is a medical intervention to alleviate pain and restore joint function in patients with severe hip conditions. This directly aligns with the definition of a therapeutic device designed to treat a medical condition.
No
Explanation: The SMS system is a hip implant used for replacement surgery to treat conditions like arthritis and fractures. It is a surgical device designed for treatment rather than diagnosis.
No
The device description clearly states that the device is a femoral stem, which is a physical implant used in hip replacement surgery. It also lists various hardware components like stems, heads, and acetabular components.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical implant for hip replacement, addressing conditions like arthritis, necrosis, fractures, and failed previous surgeries. This is a therapeutic intervention performed in vivo (within the body).
- Device Description: The description details a femoral stem, a component of a total hip prosthesis system. It mentions materials and design features relevant to surgical implantation.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze biological samples. This device is a surgical implant used in vivo.
N/A

Device Description
The SMS femoral stem is a cementless bone preserving short stem designed for proximal fixation in total or partial hip arthroplasty for primary or revision surgery.
The SMS implants are comprised of the following products:
- SMS Cementless Solid Standard Stem (available in 15 sizes from size 1 to 15); and ●
- SMS Cementless Solid Lateralized Stem (available in 15 sizes from size 1 to 15).
SMS collared solid version, has been introduced as a product range extension to the stems currently marketed as the SMS product line (K181693 and K201673). Quadra P is the collared stem currently marked in US K192827.

The SMS implants are part of the Medacta Total Hip Prosthesis system. The Medacta Total Hip Prosthesis system consists of femoral stems, modular femoral heads and acetabular components. The acetabular components consist of metal cups and liners made of ultra-high molecular weight polyethylene (UHMWPE) or Highcross highly crosslinked ultra-high molecular weight polyethylene (HXUHMWPE). Acetabular components include the Mpact DM (K143453), VersafitCup (K083116 and K092265), VersafitCup CC Trio (K103352), Mpact (K103721 and K132879), Mpact 3D Metal (K171966) and Medacta Bipolar Head (K091967).

§ 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.

VIII. Conclusion
Based on the above information, the SMS Collared implants are substantially equivalent to the identified predicate devices. Substantial equivalence has been demonstrated through a comparison of intended use, design, and technological characteristics, as well as performance evaluations. The SMS Collared implants are as safe and effective as the predicate devices, SMS solid stem, (K181693 and K201673) and Quadra P collared (K192827).
