Intended Use

The subject femoral heads are single-use devices intended for use in cemented or cementless total hip arthroplasty with various Howmedica Osteonics hip stems featuring the PCA® taper (2° 52') that are manufactured from CoCr alloy. They are not intended for use with any stem manufactured from Stainless Steel or Titanium alloy. They are also intended for use with any compatible, currently available Howmedica Osteonics acetabular component featuring a polyethylene bearing surface.

Device Story

PCA® Alumina Femoral Heads are orthopedic implants for total hip arthroplasty; 32mm diameter; manufactured from Alumina ceramic (ASTM F603) with Ti-6Al-4V alloy sleeves (ASTM F136). Device functions as a bearing surface in hip joint replacement; interfaces with CoCr alloy femoral stems via PCA® taper (2° 52') and compatible polyethylene-bearing acetabular components. Used by orthopedic surgeons in clinical/surgical settings. Provides stable articulation for hip joint; restores joint function; addresses degenerative disease or fracture. Single-use device.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on bench testing and design comparison to legally marketed predicate devices.

Technological Characteristics

Materials: Alumina ceramic (ASTM F603) head, Ti-6Al-4V alloy sleeve (ASTM F136). Dimensions: 32mm diameter, 0 (standard) and +5 offsets. Interface: PCA® taper (2° 52'). Compatibility: CoCr alloy femoral stems and polyethylene-bearing acetabular components. Non-electronic, mechanical implant.

Indications for Use

Indicated for patients with noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis (excluding specific HA-coated cups), functional deformity, failed prior treatments requiring revision, and nonunion/fractures of the proximal femur. Indicated for cementless total hip arthroplasty depending on chosen stem/acetabular components.

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

PCA® taper (2° 52') femoral heads manufactured from Alumina ceramic (ASTM F603) with a Ti-6Al-4V alloy sleeves (ASTM F136) will be available in 32mm diameters. The femoral heads will be available with 0 (standard) and +5 offsets. The PCA® taper femoral heads are compatible with a range of CoCr alloy Howmedica Osteonics PCA® taper femoral stems. The subject components are also compatible for use with a wide range of acetabular components (shells and polyethylene inserts).

### Intended Use:

The subject femoral heads are single-use devices intended for use in cemented or cementless total hip arthroplasty with various Howmedica Osteonics hip stems featuring the PCA® taper (2° 52') that are manufactured from CoCr alloy. They are not intended for use with any stem manufactured from Stainless Steel or Titanium alloy. They are also intended for use with any

compatible, currently available Howmedica Osteonics acetabular component featuring a polyethylene bearing surface.

### Indications for Use

- 1) noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis:
- rheumatoid arthritis (excepting the Osteolock" HA Acetabular Cup and Peri-2) Apatite coated prostheses):
- 3) correction of functional deformity:
- 4) revision procedures where other treatments or devices have failed; and,
- ર) treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques.

The Peri-Apatite coated prostheses are indicated only for primary uncemented total hip arthroplasty for items 1, 3, & 5 above when offered for sale in the USA.

Femoral head prostheses are indicated for use in cementless total hip arthroplasty, depending upon the indications of the acetabular and femoral stem components chosen.

## Substantial Equivalence:

The PCA® Alumina Femoral Heads are substantially equivalent to the Alumina V40™ Femoral Heads (K023901), cleared by Howmedica Osteonics Corp., PCA Total Hip System - Cementless Use (K920831), cleared by Pfizer Hospital Products Group, Inc., and the V40™/C-Taper Adapter Sleeve (K003379), cleared by Howmedica Osteonics Corp.
