The summary describes a physical implant (femoral head) and its compatibility with other physical components of a hip replacement system. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
This device is a component of a hip arthroplasty system, which is a reconstructive surgical procedure intended to treat conditions causing severe pain and disability, thus having a therapeutic effect.
No
The device is an implantable femoral head used in hip arthroplasty, which is a treatment for various hip conditions, not a device used to diagnose them.
No
The device description clearly states it is a "single use implant" and describes physical components like "femoral head," "diameters," and "neck length." It also details compatibility with other physical hip implant components.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for use in hip arthroplasty in patients with specific conditions affecting the hip joint. This is a surgical implant used in vivo (within the body).
- Device Description: The description details a femoral head, which is a component of a hip replacement implant. This is a physical device implanted into the body.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing samples (blood, urine, tissue, etc.) in vitro (outside the body).
- Providing information for diagnosis, monitoring, or screening based on the analysis of these samples.
- Reagents, calibrators, or controls used in laboratory testing.
The device described is a medical device specifically a surgical implant for hip replacement.

Device Description
UNITED U2 femoral head is a modification of the cleared UNITED femoral head (K994078, K022520, K111546, K122504 and K152439) which is intended to use in primary or revision total/hemi hip arthroplasty. U2 femoral heads include three series of products: U2 Femoral head, U2 Femoral head, 3/4 polished and U2 Femoral head, 4/5 polished.
U2 femoral heads provide five different diameters of 22 mm, 26 mm, 32 mm and 36 mm. 22 mm is available in +0, +3, +6 and +9 mm of neck length, 26 mm is available in -2, +0. +3, +6 and +9 mm of neck length and 28 mm to 36 mm are available in -3, +0, +2.5. +5, +7.5 and +10 mm of neck length. A variety of diameters and neck lengths are available for various patient anatomies, adjustment of the tension of the ligaments, and reconstruction of the center of the physiological head of the femur.
U2 femoral heads is design for compatibility with various types of UNITED Hip Stem (K062978, K003237, K003237, K151316, K111546, K111546, K152530, K123550, K132207). For total hip replacement, U2 femoral heads can be used in conjunction with U2 Acetabular Cup Liner (K050262), XPE Cup Liner (K111546), U2 HA/Ti Plasma Spray Cup (K050262, K121777), U2 Ti Plasma Spray Cup (K050262, K121777), U2 Ti Porous Coated Cup (K111546) and U-Motion II Acetabular System (K122185, K132455). For hemi hip arthroplasty, U2 femoral heads can be used with U2 Bipolar Implant (K152439).

§ 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)

Device Description:
UNITED U2 femoral head is a modification of the cleared UNITED femoral head (K994078, K022520, K111546, K122504 and K152439) which is intended to use in primary or revision total/hemi hip arthroplasty. U2 femoral heads include three series of products: U2 Femoral head, U2 Femoral head, 3/4 polished and U2 Femoral head, 4/5 polished.
U2 femoral heads provide five different diameters of 22 mm, 26 mm, 32 mm and 36 mm. 22 mm is available in +0, +3, +6 and +9 mm of neck length, 26 mm is available in -2, +0. +3, +6 and +9 mm of neck length and 28 mm to 36 mm are available in -3, +0, +2.5. +5, +7.5 and +10 mm of neck length. A variety of diameters and neck lengths are available for various patient anatomies, adjustment of the tension of the ligaments, and reconstruction of the center of the physiological head of the femur.
U2 femoral heads is design for compatibility with various types of UNITED Hip Stem (K062978, K003237, K003237, K151316, K111546, K111546, K152530, K123550, K132207). For total hip replacement, U2 femoral heads can be used in conjunction with U2 Acetabular Cup Liner (K050262), XPE Cup Liner (K111546), U2 HA/Ti Plasma Spray Cup (K050262, K121777), U2 Ti Plasma Spray Cup (K050262, K121777), U2 Ti Porous Coated Cup (K111546) and U-Motion II Acetabular System (K122185, K132455). For hemi hip arthroplasty, U2 femoral heads can be used with U2 Bipolar Implant (K152439).
Indications for Use:
5
త్ U2 Femoral Head
The device is indicated for use in hip arthroplasty in patients with the following conditions:
-
- A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis or congenital hip dysplasia.
-
- Avascular necrosis of the femoral head.
- Acute traumatic fracture of the femoral head or neck. 3.
-
- Failed previous hip surgery.
This device is a single use implant and intended for cementless use only except cemented stem which is designed for cemented use only.
Comparison to Predicate Device:
U2 Femoral Head has the same material, basic design, indications, dimension characteristic and sterilization method as the predicate devices, UNITED femoral heads (K994078, K022520, K111546, K122504 and K152439). The differences between the subject and the predicate devices are the chamfer design and the neck length. The chamfer design change would not affect the intended use and performance of the device. The mechanical performance of the subject device was analyzed and the result showed that these design features would not post issues about safety and effectiveness. Thus, we believe that the subjected U2 Femoral Head is substantially equivalent to the predicate device.
Performance Data:
-
Non-clinical Performance
Tests as follows were conducted to evaluate the safety and effectiveness of the subjected device. -
a. Disassembly force between U2 femoral head and stem component
-
b. Range of Motion
-
c. Bacterial endotoxin testing was conducted and met the endotoxin limit as specified in USP .
Performance data demonstrate the device is as safe and effective and is substantially equivalent to the legally marketed predicate devices.
