Intended Use

The DePuy Delta TS Ceramic Femoral Head is intended for use in total hip arthroplasty applications to replace the articular surface of the femoral head in primary hip surgery and for the salvage of a failed previous hip surgery.

Device Story

Ceramic femoral head prosthesis for total hip arthroplasty; replaces damaged femoral head articular surface. Device consists of alumina composite ceramic head with internal titanium alloy sleeve; mechanically locks onto femoral hip stem via taper junction; articulates with polyethylene acetabular component. Used in clinical settings by orthopedic surgeons. Provides stable joint articulation; restores mobility; reduces pain. Available in 28mm, 32mm, 40mm, and 44mm diameters with 12/14 taper option.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Alumina composite ceramic femoral head; titanium alloy internal sleeve. 12/14 taper junction. Diameters: 28mm, 32mm, 40mm, 44mm. Mechanical fixation via taper lock. Articulates with polyethylene acetabular components.

Indications for Use

Indicated for use as femoral head component in total hip arthroplasty to increase mobility and reduce pain in patients with sufficient bone stock. Conditions include: osteoarthritis, traumatic arthritis, rheumatoid arthritis, congenital hip dysplasia, avascular necrosis, acute traumatic fracture of femoral head/neck, failed previous hip surgery (reconstruction, fixation, arthrodesis, hemiarthroplasty, surface replacement), and ankylosis.

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:

The DePuy Delta TS (Taper Sleeve) Ceramic Femoral Heads are designed for use as the femoral head component in total hip arthroplasty procedures. The femoral head is manufactured from an alumina composite ceramic material and includes an internal titanium alloy sleeve to mate with DePuy femoral hip stems with a corresponding taper. The ceramic femoral head mechanically locks with the femoral hip stem via a taper junction, and articulates with a polyethylene acetabular component.

The subject DePuy Delta TS Ceramic Femoral Heads are available in femoral head outer diameters of 28mm, 32mm, 40mm and 44mm. The internal bore of the titanium sleeve is available in a 12/14 option.

#### INTENDED USE AND INDICATIONS FOR USE:

## Intended Use:

The DePuy Delta TS Ceramic Femoral Head is intended for use in total hip arthroplasty applications to replace the articular surface of the femoral head in primary hip surgery and for the salvage of a failed previous hip surgery.

#### Indications for Use:

The DePuy Delta TS Ceramic Hip Head Prosthesis is indicated for use as the femoral head component in total hip arthroplasty procedures.

Total hip arthroplasty is intended to provide increased patient mobility and reduce pain by replacing the damaged hip joint articulation in patients where there is evidence of sufficient sound bone to seat and support the components. Total hip replacement is indicated in the following conditions:

- 1. A severely painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia.
- 2. Avascular necrosis of the femoral head.
- 3. Acute traumatic fracture of the femoral head or neck.
- 4. Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement.
- 5. Certain cases of ankylosis.

# BASIS OF SUBSTANIAL EQUIVALENCE:

The DePuy Delta TS Ceramic Femoral Heads described in this submission are substantially equivalent to the predicate devices based on similarities in intended use and
