## Intended Use

This device is indicated in hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: - Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia; - Inflammatory degenerative joint disease such as rheumatoid arthritis; - Correction of function deformity; - Revision procedures where other treatments or devices have failed; - Treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement that is unmanageable using other techniques. This device is a single use implant and intended for cementless use only except cemented stem which is designed for cemented use only.

## Device Story

U2 Hip System is a total hip prosthesis consisting of femoral and acetabular components. It is a single-use implant intended for surgical implantation by orthopedic surgeons in a hospital setting. The system is designed for cementless use, with the exception of specific stems designed for cemented use. The device functions as a mechanical replacement for the hip joint to restore function and reduce pain. This submission serves to unify and expand the indications for use across several previously cleared U2 and U1 hip system components. No changes were made to the device design, materials, or manufacturing processes.

## Clinical Evidence

No clinical data provided. Substantial equivalence is based on the identical technological characteristics to previously cleared predicate devices.

## Technological Characteristics

Total hip prosthesis (metal/polymer/metal semi-constrained porous-coated uncemented). Components include femoral stems, acetabular cups, and femoral heads. Materials, design, and sterilization methods are identical to predicate devices. No software or electronic components.

## Regulatory 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.

#### ਹ U2 Hip System, Expanded Indications for Use

### Device Description:

There are two purposes in current submission, the fist one is to expand the Indications for Use of two cleared products: U2 Hip System (K111546) and Femoral Heads, +2.5 & +7.5 mm Offset (K122504), which have been expanded to a population with similar demographic, diagnosis and prognosis as the original. The second purpose of this submission is to reword the statement of Indications for Use of six cleared "UNITED" hip products including U1 Hip System (K994078), U2 Hip Stem, Ti porous coated (K003237), U2 Acetabular Cup and Femoral Head (K022520), U2 Acetabular Component (K050262), U2 Hip Stem and Ti Plasma Spray (K062978) and U2 Acetabular Cup, Plasma Spray (K121777). Through this submission, the Indications for Use of above listed devices are unified as one version, and the components, materials, design, processing methods, sterilization methods, biocompatibility, safety and effectiveness of above listed devices are unchanged by this submission.

## Indications for Use:

This device is indicated in hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:

- Non-inflammatory degenerative joint disease such as osteoarthritis, avascular 1. necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia;
- Inflammatory degenerative joint disease such as rheumatoid arthritis; 2.
- Correction of function deformity; 3.
- · 4. Revision procedures where other treatments or devices have failed;
	- Treatment of nonunion, femoral neck and trochanteric fractures of the proximal 5. femur with head involvement that is unmanageable using other techniques.

This device is a single use implant and intended for cementless use only except cemented stem which is designed for cemented use only.

510(k) Summary

## Basis for Substantial Equivalence:

The components, design, materials, packaging materials and sterilization method of U2 Hip System- Expanded Indications for Use are identical to cleared predicate devices:

1. "UNITED" U1 Hip System (K994078)

2. "UNITED" U2 Hip Stem, Ti porous coated (K003237)

3. "UNITED" U2 Acetabular Cup and Femoral Head (K022520)

4. "UNITED" U2 Acetabular Component (K050262)

5. "UNITED" U2 Hip Stem, Ti Plasma Spray (K062978)

6. "UNITED" U2 Hip System (K111546)

7. "UNITED" U2 Acetabular Cup, Plasma Spray (K121777)

8. "UNITED" Femoral Heads, +2.5 & +7.5 mm Offset (K122504)

The only difference between the proposed and predicate devices is the integration of Indications for Use. The submitted indications are substantially equivalent to the predicate products and do not affect the functional effectiveness and safety.

Besides, the indications are substantially equivalent to legally marketed "WRIGHT" STEM Hip Replacement System (K021346), "HOWMEDICA" Stryker Modular Hip System (K071082) and "BIOMET" Medallion Modular Hip System (K041850) for total hip replacement. In the other hand, for bipolar hip replacement, the indications of current submission are identical to "UNITED" U1 Hip System-Bipolar (K050269) and "UNITED" U2 Bipolar Implant (K101670), and are also equivalent to "Smith & Nephew" Global Bipolar System (K023743) and "BIOMET" RingLoc® Bi-Polar Acetabular Component (K051569).

## Summary of Technologies

Dear Fang-Yuan Ho:

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. Iisting 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
