Intended Use

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: - Severely painful and/or disabled joint from 1. osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia. - 2. Avascular necrosis of the femoral head. - 3. Acute traumatic facture 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. The Porocoat® Prodigy™ Hip Stem is indicated for cementless use and fixation by biological tissue ingrowth into the porous coating as well as cemented use and fixation in which the porous coating serves as a means to augment the fixation of the prostheses to the bone cement.

Device Story

Porocoat® Prodigy™ Hip Prosthesis; femoral hip stem for total hip arthroplasty. Manufactured from ASTM F-75 Cobalt-Chromium-Molybdenum alloy; features sintered cobalt-chrome-molybdenum alloy bead porous coating (Porocoat®) for biological fixation or cement augmentation. Designed for use with AML reamers, broaches, and Excel®/AML impactors. Anteverted neck design accepts femoral ball heads (cobalt-chromium-molybdenum alloy or aluminum ceramic). Used in combination with metal-backed acetabular cup and UHMWPe bearing surface. Intended for surgical implantation by orthopedic surgeons to replace damaged hip joint articulation, increase patient mobility, and reduce pain.

Clinical Evidence

No clinical data provided; substantial equivalence based on design, material, and technological similarities to predicate devices.

Technological Characteristics

Material: ASTM F-75 Cobalt-Chromium-Molybdenum alloy. Coating: Sintered cobalt-chrome-molybdenum alloy bead porous coating. Design: Anteverted neck, tapered for femoral ball heads. Compatibility: AML reamers, broaches, Excel®/AML impactors. Fixation: Cementless (biological ingrowth) or cemented. Sterilization: Identical to predicates.

Indications for Use

Indicated for patients requiring total hip arthroplasty due to osteoarthritis, traumatic arthritis, rheumatoid arthritis, congenital hip dysplasia, avascular necrosis of the femoral head, acute traumatic fracture of the femoral head/neck, failed previous hip surgery, or ankylosis, provided sufficient sound bone exists to support components.

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.

## 510(k) Summary (continued)

metal backed acetabular cup prosthesis that uses an ultra high molecular weight polyethylene bearing (UHMWPe) surface.

Intended use: 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:

- Severely painful and/or disabled joint from 1. osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia.
- 2. Avascular necrosis of the femoral head.
- 3. Acute traumatic facture 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.
- న్. Certain cases of ankylosis.

The fundamental scientific technologies of the Prodigy Hip Prosthesis have not changed from the FDA cleared Prodigy Hip Prosthesis system (K931641) and the Vision AML Hip System (K953694). The intended use and indications for use of the Prodigy Hip Prosthesis have not changed from the FDA cleared Prodigy Hip Prosthesis system (K931641). The Prodigy hip stem is manufactured from ASTM F-75 Cobalt Chromium Molybdenum alloy as are the Prodigy hip stem cleared in K931641 and the Vision AML Hip System (K953694). With the exception of the minor design modifications, the Prodigy hip stem is identical to the Prodigy hip stem device cleared in K931641.

Based on conformance with the design control procedures requirements as specified in 21 CFR 820.30, similarities of design, commonly used materials, identical sterilization processes, the same indications for use and intended use, DePuy believes that the Porocoat Prodigy Hip Prosthesis to be substantially equivalent to the FDA cleared Prodigy Hip Prosthesis system (K931641) and the Vision AML Hip System (K953694).

Substantial equivalence:
