No
The description focuses solely on the material, geometry, and mechanical properties of a hip stem implant. There is no mention of any software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is a hip stem intended for total hip arthroplasty to treat various degenerative joint diseases and fractures, which falls under the definition of a therapeutic device designed to treat a medical condition.
No
The device is a hip stem used in total hip arthroplasty, which is a treatment for various hip conditions, not a tool for diagnosing them.
No
The device description clearly details a physical implant made of Ti-6Al-4V alloy with specific dimensions, geometry, and coating, intended for surgical implantation in the hip. This is a hardware medical device, not 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 treating hip joint conditions. This is a therapeutic device, not a diagnostic one.
- Device Description: The description details the materials, geometry, and components of a hip stem, which is a physical implant.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information about a patient's condition.
- Anatomical Site: The device is used within the body (hip, proximal femur), which is typical for a surgical implant, not an IVD.
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.

Intended Use / Indications for Use
The Global Press-fit Hip Stem is intended for treating patients who are candidates for total hip arthroplasty because of: degenerative joint disease, including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedures where other treatments or devices have failed; and treatment of non-union, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques. It is intended for cementless use.

Device Description
The Global Press-fit stem is manufactured from Ti-6Al-4V alloy that conforms to ASTM F136. It is available is sizes ranging from 9mm to 17mm. The body tapers proximal to distal in the lateral and frontal planes, and lateral to medial in the sagittal plane resulting in a tri-planar wedge geometry that is conducive to axial and rotational stability. The distal stem is conical in shape with sharp splines to enhance rotational stability. Stems larger than 11mm have a coronal slot in the distal third to aid in the reduction of thigh pain.
A Morse type taper is used to attach modular femoral heads. The stem is available with neutral, and right and left anteverted necks. No calcar collar is present on this stem. The proximal lateral shoulder of the stem has a threaded hole for insertion and extraction tools.
The proximal body of the stem has a circumferential porous coating of sintered CP titanium beads (ASTM F67).
The femoral heads utilized with the Global Press-fit Hip are machined from wrought CoCrMo alloy (ASTM F799). They are available in 22mm, 28mm diameters. The 22mm heads have two neck lengths, while the 28mm and 32mm heads have five neck lengths.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The stem geometry of the Global Press-fit stem is similar to the Foundation Hip. They both are fabricated from Ti-6A1-4V alloy and undergo the exact same porous coating process. Therefore, as long as there are no geometrical features in the area where the stems would fail while being tested per ISO 7206-4 an engineering analysis is a valid method to compare the strength of these two press-fit stems.
The results of this analysis show that the strength of the Global 9mm Hip is virtually the same as the Foundation 8mm Porous Hip.

§ 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)
