Intended Use

The DePuy Pinnacle Acetabular System is intended to resurface the acetabular socket in cemented or cementless total hip arthroplasty. The Pinnacle Acetabular System is indicated for total hip replacement 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. All Pinnacle porous-coated acetabular shells are indicated for cementless application.

Device Story

Modular acetabular cup prosthesis for total hip arthroplasty; consists of porous-coated hemispherical titanium alloy (Ti-6Al-4V) outer shell and UHMWPE liner. Liner locks into shell and articulates with femoral head. Used by orthopedic surgeons in clinical settings for hip joint replacement. Provides stable acetabular socket surface to restore joint function and reduce pain in patients with degenerative or traumatic hip conditions.

Clinical Evidence

Bench testing only; no clinical data provided.

Technological Characteristics

Modular acetabular cup system. Materials: Titanium alloy (Ti-6Al-4V) for porous-coated shell; UHMWPE for liner. Cementless application. Non-software device.

Indications for Use

Indicated for patients requiring total hip replacement due to osteoarthritis, traumatic arthritis, rheumatoid arthritis, congenital hip dysplasia, avascular necrosis of the femoral head, acute traumatic fracture of the femoral head or neck, failed previous hip surgery (reconstruction, fixation, arthrodesis, hemiarthroplasty, surface replacement), or ankylosis.

Regulatory Classification

Identification

A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.

#### DEVICE DESCRIPTION AND INTENDED USE:

The Pinnacle Acetabular System is indicated for total hip replacement 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.

JUN 1 2 2000

All Pinnacle porous-coated acetabular shells are indicated for cementless application.

The Pinnacle Acetabular System is part of a modular system for use in total hip replacement. The acetabular component is provided as two separate units, a porous coated hemispherical outer shell manufactured from titanium alloy (Ti-6Al-4V) and a liner manufactured from ultra high molecular weight polyetheylene (UHMWPE), which locks into the outer shell. The liner component articulates with a femoral head of an appropriate diameter.

### BASIS OF SUBSTANTIAL EQUIVALENCE:

The Pinnacle Acetabular System has the following similarities to the acetabular cup liners that were cleared in K000306: same intended use; same material; same method of manufacture; same design; same sterilization and packaging methods. The Pinnacle Acetabular System demonstrated adequate performance in design control activities.
