Intended Use

Prosthetic replacement of the femoral head associated with a hip prosthesis having a taper compatible with the head taper, and with a prosthetic acetabulum having an inside diameter compatible with that of the head. The alumina head can only be used with polyethylene inserts. This prothesis may be used for degenerative ioint disease such as osteoarthritis and avascular necrosis, correction of functional deformity, rheumatoid arthritis, revision procedure where other devices or treatments have failed, congenital dislocation, femoral neck and trochanteric fractures, traumatic arthritis, fused diastrophic variant, slipped capital hip, epiphysis, non-union.

Device Story

Alumina heads serve as prosthetic femoral components in hip arthroplasty. Device consists of ceramic ball (Biolox forte or HIP Vitox alumina) with 10/12 or 12/14 taper interface. Available in 28mm and 32mm diameters with varying offsets. Used by orthopedic surgeons in clinical settings during total hip replacement or revision procedures. Device mates with compatible femoral stem taper and UHMWPE acetabular liner. Provides load-bearing surface for hip joint articulation; intended to restore joint function and mobility in patients with degenerative or traumatic hip conditions. Safety and effectiveness validated via fatigue testing, static compression to rupture, and head extraction force measurements.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included fatigue testing, static compression to rupture, and head extraction force measurement (2000 N pre-load). Results demonstrated compliance with FDA requirements and ISO 6474 standards.

Technological Characteristics

Material: Biolox forte or HIP Vitox alumina (ISO 6474). Geometry: 10/12 or 12/14 cone taper; 28mm/32mm diameters; -3.5, 0, +3.5 offsets. Mechanical interface: Ceramic-to-metal taper, ceramic-to-UHMWPE articulation. Non-active, non-software device.

Indications for Use

Indicated for patients requiring femoral head replacement due to degenerative joint disease (osteoarthritis, avascular necrosis), functional deformity, rheumatoid arthritis, revision surgery, congenital dislocation, femoral neck/trochanteric fractures, traumatic arthritis, fused diastrophic variant, slipped capital hip, epiphysis, or non-union. Contraindicated for use without compatible polyethylene inserts.

Regulatory Classification

Identification

A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

## DEVICE DESCRIPTION:

Alumina heads are made of Biolox forte alumina (trademark of CERAMTEC) according to ISO 6474 standard.

Alumina heads have a 12/14 cone and are available in two diameters: 28mm and 32mm, with three offsets: -3.5; 0; +3.5.

This special 510 (k) is being submitted to propose an extension at the 10/12 cone in diameter : 32 mm with three offsets: -3.5; 0; +3.5. This heads are made in HIP Vitox® alumina (trademark of Morgan Advanced Ceramics Ltd according to ISO 6474 standard.

### INDICATIONS FOR USE:

Prosthetic replacement of the femoral head associated with a hip prosthesis having a taper compatible with the head taper, and with a prosthetic UHMWPE acetabulum having an inside diameter compatible with that of the head.

### PREDICATE DEVICES:

The proposed Alumina heads are now provided with a 10/12 cone. They have exactly the same intented use and same design as the predicate devices.

Regarding the material, numerous alumina heads are made in alumina in accordance ISO 6474 standard.

And regarding the design, numerous femoral heads made in 10/12 cone with a diameter 32.

So, we have selected two predicate devices based upon intended uses, material used in device manufacturing and design features.

These predicate devices are:

- Alumina Head (K042035), F.H. Industrie l
- ESOP® Co-Cr femoral head (K021109), F.H. Industrie -

## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS:

Our alumina heads have the same intended use and substantial similar indications for use as the predicate devices. They are all made of the same material (Alumina), are available in similar diameters and lengths, with similar designs (10/12 cone).

… そ

Performance tests were performed. Our proposed devices and the predicate devices were found to have results in compliance with the selected standard.

#### MATERIAL CHARACTERISTICS:

We have followed the FDA's guideline: "Guidance document for the preparation of premarket notifications for ceramic ball hip systems" dated January 10, 1995 to compare if our material characteristics were in conformity with the FDA requirements. Our 10/12 cone alumina heads reach all the requirements set up in this guidance document.

#### PERFORMANCES:

To evaluate the safety and effectiveness of our Alumina heads, we have made three series of tests:

- Fatigue test and static compression test to rupture in the first series -
- Test of static compression to rupture in the second series …
- Pre-loading of femoral head on its neck at 2000 N and measurement of the head extraction force in the thrid series.

All the results were in compliance with the requirements set forth by the FDA. Risk to health have been addressed through the specified materials, Processing controls, quality assurance and compliance to the Medical Device Good Manufacturing Practices Regulations.

#### CONCLUSION:

All these elements show the safety and effectiveness of our product. Our 10/12 cone Alumina heads are substantially equivalents to the selected predicate device in terms of intended use, material, safety and effectiveness.
