Device Story

Bipolar hip system for hemi-arthroplasty; consists of bipolar liner, retaining ring, and femoral head. Articulates with natural acetabulum (outer) and femoral head (inner). Used in conjunction with MUTARS® Proximal Femoral Replacement System or EcoFit® Hip System. Intended for orthopedic surgeons in clinical settings. Provides stable articulation for patients requiring proximal femur replacement or fracture treatment; restores joint function; facilitates limb salvage.

Clinical Evidence

Bench testing only. Characterization included UHMWPE testing, taper disassembly, modular disassembly, range of motion, and endotoxin testing. Testing performed on units representative of finished devices to demonstrate substantial equivalence.

Technological Characteristics

Components: bipolar liner, retaining ring, femoral head. Materials: CoCrMo alloy and UHMWPE. Design: Bipolar articulation (inner/outer). Intended for uncemented use. No software or electronic components.

Indications for Use

Indicated for skeletally mature patients requiring hemi-arthroplasty. Specific populations: oncology cases requiring radical resection, limb salvage (trauma, failed prosthesis), non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity correction, and treatment of non-union, femoral neck, or trochanteric fractures.

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

• Aesculap Bipolar Acetabular Cup (K060707)

Reference Devices

• MUTARS® Proximal Femur Replacement System (K181778)

Dear Dave Mcgurl:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

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.

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); medical device reporting of medical device-related adverse events) (21 CFR 803) for

## Indications for Use:

The ic-Bipolar Heads is for uncemented use in conjunction with the MUTARS® Proximal Femoral Replacement System for the following indications:

- Proximal femur replacement in oncology cases where radical resection and replacement । of bone is required.
- Limb salvage procedures including surgical intervention for severe trauma, failed । previous prosthesis, and/or oncology indications, where radical resection and replacement of the bone is required.

Use of this prosthesis is generally only indicated in skeletally mature patients.

The ic-Bipolar Heads is for uncemented use in conjunction with the EcoFit® Hip System for the following indications:

- । Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis
- Rheumatoid arthritis --
- | Correction of functional deformity
- -Treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques.

## Device Description:

The ic-Bipolar Head System consists of a bipolar liner, retaining ring, and femoral head. The system is used for hip replacements in which the femur requires replacement but the acetabulum does not (i.e. hemi-arthroplasty) The ic-Bipolar Head System articulates directly with the natural (non-replaced) acetabulum on the outer side and with a femoral head on the inner side. The ic-Bipolar Head System is manufactured of CoCrMo and UHMWPE. The ic-Bipolar Head System is used in conjunction with the EcoFit® Hip System (K163577) and MUTARS® Proximal Femur Replacement System (K181778).

## Performance Testing:

All necessary testing has been performed for the worst-case configuration of the ic-Bipolar Head System to assure substantial equivalence to its predicates and to demonstrate the subject devices perform as intended. All testing was performed on test units representative of finished devices. The performance of the ic-Bipolar Head System was characterized through the following tests:

- UHMWPE Characterization ●
- o Taper Disassemblv
- Modular Disassembly
- Range of Motion
- Endotoxin Testing

## Substantial Equivalence:

Like the ic-Bipolar Head System, the Aesculap BiPolar Acetabular Cup predicate incorporates nearly identical geometry, similar or identical sizes (28mm), and corresponding indications for use. Like the ic-Bipolar Head System, the predicate is also manufactured from medical grade

{5}------------------------------------------------

CoCrMo Alloy and UHMWPE. Both components are intended to be used with a hip stem and articulate against the natural acetabulum. The ic-Bipolar Head System is substantially equivalent with respect to materials, indications, function and performance to Aesculap Bipolar Acetabular Cup (K060707).
