Intended Use

Non-cemented total joint replacement in cases of: 1) Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis 2) Rheumatoid arthritis 3) Correction of functional deformity 4) Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques. 5) Revision of previously failed total hip arthroplasty

Device Story

X-Series Integral® Hip Femoral Components are orthopedic implants for non-cemented total hip replacement. Device serves as femoral component in hip arthroplasty. Design is identical to predicate Integral® Hip Femoral Component (K984296) in overall geometry, with added stem diameters and lengths and a 6mm medial shift of the insertion hole. Used by orthopedic surgeons in clinical settings to restore hip function and treat degenerative disease or fractures. Benefits include structural support for hip joint reconstruction.

Clinical Evidence

No clinical data provided. Safety and effectiveness supported by Finite Element Analysis and engineering analysis.

Technological Characteristics

Titanium alloy (Ti-6Al-4V) per ASTM F-620. Semi-constrained, porous-coated, uncemented hip prosthesis. Design features include varied stem diameters/lengths and medialized insertion hole.

Indications for Use

Indicated for patients requiring non-cemented total hip arthroplasty due to degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, proximal femur fractures (non-union, femoral neck, trochanteric), or revision of failed total hip arthroplasty.

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.

Proprietary Name: X-Series Integral® Hip Femoral Components

Common Name: Hip replacement prosthesis

Classification Name: Prosthesis, hip, semi-constrained, metal/polymer, porous coated uncemented (21 CFR 888.3558)

Legally Marketed Device to which Substantial Equivalence is Claimed: Integral® Hip Femoral Component (K984296)

Device Description: The X-Series Integral® femoral components are identical to the predicate Integral® femoral components in overall geometry. Both device series are manufactured from titanium alloy (Ti-6AI-4V) conforming to ASTM F-620. Additional stem diameters and lengths have been added to the product line. The insertion hole has been moved medially by 6mm.

Indications for Use: Non-cemented total joint replacement in cases of:

- 1) Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis
- 2) Rheumatoid arthritis
- 3) Correction of functional deformity
- 4) Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques.
- 5) Revision of previously failed total hip arthroplasty

Summary of Technologies: The technological characteristics (materials, design, sizing and indications) of the X-Series Integral® femoral components are similar to or identical to the predicate device.

Dear Ms. Beres:

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
