Intended Use
The ZMR Hip System is indicated for cementless revision hip arthroplasty. Arthroplasty should be performed only when more conservative methods of treatment have failed to provide symptomatic relief or when there is progressive disability.
Device Description
The ZMR Hip System is a modular hip system for cementless revision hip arthroplasty. The stem assembly is manufactured from Tivanium® Ti-6Al-4V Alloy and utilizes modular junctions between the head and neck, and the metaphyseal body and diaphyseal stem segments. A variety of body and stem components are provided to achieve fixation and restore joint kinematics. The femoral stem assembly contains a 12/14 taper designed to mate with the corresponding femoral head component. The stems may be used for total hip and hemi-hip arthroplasty. During total hip arthroplasty, the stems may be combined with constrained or semiconstrained acetabular systems and acetabular augments, restrictors, and cages. Both the indications for use provided below and the indications for use provided with those devices combined with the ZMR Hip System must be followed.

No
The summary describes a mechanical hip implant system and does not mention any software, algorithms, or AI/ML capabilities.

Yes
The ZMR Hip System is indicated for cementless revision hip arthroplasty, which is a medical procedure to replace an arthritic or damaged hip joint, thus providing therapeutic relief for a patient's condition.

No

Explanation: The device is a hip implant system used for surgical replacement of the hip joint, not for diagnosing medical conditions.

No

The device description clearly states it is a "modular hip system" manufactured from "Tivanium® Ti-6Al-4V Alloy" and includes "stem assembly," "body and stem components," and a "femoral stem assembly." These are physical hardware components, not software.

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

Here's why:

  • Intended Use: The intended use is for "cementless revision hip arthroplasty," which is a surgical procedure to replace a hip joint. This is a therapeutic intervention performed in vivo (within the body).
  • Device Description: The description details a "modular hip system" made of metal components designed to be implanted in the hip. This is a medical device used for surgical reconstruction.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are used in vitro (outside the body) to analyze samples and provide diagnostic information. This device is clearly designed for surgical implantation in vivo.

§ 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)
Classification. Class II.

Comparison to Predicate Device:

Performance Data (Nonclinical and/or Clinical):

The ZMR Hip System is a modular hip system for cementless revision hip arthroplasty. The stem assembly is manufactured from Tivanium® Ti-6Al-4V Alloy and utilizes modular junctions between the head and neck, and the metaphyseal body and diaphyseal stem segments. A variety of body and stem components are provided to achieve fixation and restore joint kinematics. The femoral stem assembly contains a 12/14 taper designed to mate with the corresponding femoral head component.

The stems may be used for total hip and hemi-hip arthroplasty. During total hip arthroplasty, the stems may be combined with constrained or semiconstrained acetabular systems and acetabular augments, restrictors, and cages. Both the indications for use provided below and the indications for use provided with those devices combined with the ZMR Hip System must be followed.

The ZMR Hip System is indicated for cementless revision hip arthroplasty. Arthroplasty should be performed only when more conservative methods of treatment have failed to provide symptomatic relief or when there is progressive disability.

The ZMR Hip System is similar or identical in intended use, materials, sterility, and performance characteristics to the predicate device(s).

Non-Clinical Performance and Conclusions:

The results of non-clinical (lab) performance testing demonstrate that the devices are safe and effective and substantially equivalent to the predicate devices. Performance testing/analysis included Fretting Fatigue Testing and Range of Motion Analyses.

Dear Mr. Williman:

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. 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.
