## Intended Use

The Orthopedic Source Hip Stem is intended for treating patients who are candidates for total hip arthroplasty because of: degenerative joint disease, including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedures where other treatments or devices have failed; and treatment of non-union, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques. It is intended for cementless use.

## Device Story

Orthopedic Source Press-fit Hip is a collarless, flat, wedge-shaped femoral stem implant. Manufactured from Ti-6Al-4V alloy (ASTM F136) with proximal circumferential commercially pure titanium plasma spray coating. Features 135° neck-shaft angle and 12/14 Morse taper for modular femoral heads (wrought CoCrMo alloy, ASTM F799). Implanted by surgeons in clinical settings for total hip arthroplasty. Design facilitates self-seating and rotational stability. Modular offset options allow reconstruction of joint stability and leg length. Benefits include durable, stable fixation for patients with degenerative joint disease, rheumatoid arthritis, or proximal femur fractures. Device is cementless.

## Clinical Evidence

Bench testing only. Engineering analysis performed to compare mechanical strength against the predicate device.

## Technological Characteristics

Material: Ti-6Al-4V alloy (ASTM F136) stem; CoCrMo alloy (ASTM F799) femoral heads. Coating: Commercially pure titanium plasma spray. Geometry: Collarless, flat wedge-shaped stem; 135° neck-shaft angle; 12/14 Morse taper. Fixation: Cementless, porous-coated. Dimensions: 22mm, 28mm, 32mm head diameters.

## Regulatory 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

The Orthopedic Source stem is manufactured from Ti-6Al-4V alloy that conforms to ASTM F136. It is a collarless flat wedge-shaped implant that provides excellent durability and stability in a design that is relatively simple and predictable to implant. The use of a collarless designity the Orthopedic Source hip tends to allow for self seating of the implant and achievement of optimal rotational stability, immediately after implantation. The incorporation of standard and lateralized offset options provides the surgeon the ability to reconstruct a stable joint with proper leg length in virtually all patient anatomies. The Orthopedic Source Stem has a 135° rack shaft angle and a standard 12/14 Morse type taper is incorporated in to the geometry to receive modular heads. The proximal body is circumferentially coated with commercially pure titanium plasma spray. Femoral heads are manufactured from wrought CoCrMo alloy conforming to ASTM F799 and are available in 22m, 28mm and 32mm diameters and multiple neck lengths.

## Intended Use

The Orthopedic Source Hip Stem is intended for treating patients who are candidates for total hip arthroplasty because of: degenerative joint disease, including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedures where other treatments or devices have failed; and treatment of non-union, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques. It is intended for cementless use.

## Summary of Technological Characteristics Compared to Predicate Device

The results of an engineering analysis shows that the strength of the Orthopedic Source 7.5mm Offset Hip is slightly greater than the Taperloc 7.5mm Hip.

Dear Mr. Webb:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
