Intended Use

The Global Bipolar System is indicated for the following: - 1. Non-inflammatory degenerative joint disease including osteoarthritis, osteonecrosis, avascular necrosis and post traumatic arthritis; - 2. rheumatoid arthritis; - arthritis secondary to a variety of diseases and anomalies and correction 3. of functional deformity such as congenital hip dysplasia or ankylosing spondylitis; - revision procedures where other treatment or devices have failed; and 4. - treatment of proximal femoral non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement.

Device Story

Global Bipolar System is a hip joint femoral (hemi-hip) prosthesis; consists of bipolar liner, full lock ring liner, and metal retaining ring. Used with existing Smith & Nephew femoral heads. Intended for surgical implantation in patients requiring hip joint replacement or revision. Device functions as a mechanical bearing surface to restore joint mobility and function. Operates as a passive orthopedic implant; no electronic or software components. Clinical benefit includes pain relief and restoration of hip function in patients with degenerative joint disease or fractures.

Clinical Evidence

Bench testing only; no clinical data provided. Mechanical testing demonstrated equivalence to predicate devices in supporting expected in vivo loading.

Technological Characteristics

Hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis. Components include bipolar liner, full lock ring liner, and metal retaining ring. Passive mechanical implant design.

Indications for Use

Indicated for patients with non-inflammatory degenerative joint disease (osteoarthritis, osteonecrosis, avascular necrosis, post-traumatic arthritis), rheumatoid arthritis, functional deformity (congenital hip dysplasia, ankylosing spondylitis), revision needs, or proximal femoral fractures/non-union.

Regulatory Classification

Identification

A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement (§ 888.3027) or implanted by impaction.

Predicate Devices

• Smith & Nephew Bipolar System
• Centrax Bipolar System
• Multipolar Bipolar System
• Self-Centering Bipolar System
• Ringloc Bipolar System

### Substantial Equivalence Information

The Global Bipolar System is substantially equivalent to the following: Smith & Nephew Bipolar System, Centrax Bipolar System; Multipolar Bipolar System; Self-Centering Bipolar System; and the Ringloc Bipolar System.

#### Device Description

The Global Bipolar System consists of a bipolar liner, full lock ring liner, and a metal retaining ring. The system is to be used with existing femoral heads distributed by Smith & Nephew.

#### Indications for Use

The Global Bipolar System is indicated for the following:

- Non-inflammatory degenerative joint disease including osteoarthritis, 1. osteonecrosis, avascular necrosis and post traumatic arthritis;
- 2. rheumatoid arthritis;
- arthritis secondary to a variety of diseases and anomalies and correction of 3. functional deformity such as congenital hip dysplasia or ankylosing spondylitis;
- revision procedures where other treatment or devices have failed; and ধ:
- treatment of proximal femoral non-union, femoral neck fracture, and trochanteric న. fractures of the proximal femur with head involvement.

### Technological & Performance Characteristics:

The Global Bipolar System is similar to currently marketed bipolar systems. The components share the same intended use, material, and design features of one or more of the above mentioned predicates. A review of the mechanical test data indicated that the Global Bipolar System is equivalent to devices currently on the market and are capable of withstanding expected in vivo loading without failure.

Dear Ms. Akil:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807): labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
