Intended Use

The ArComXL™ Polyethylene Rx90™ Low Profile Acetabular Liners are indicated for single cemented or non-cemented use 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

ArComXL™ Polyethylene Rx90™ Low Profile Acetabular Liners are orthopedic implants used in total hip arthroplasty. The device serves as a bearing surface within the acetabular component of a hip prosthesis. It is manufactured from ArComXL™ polyethylene and is available in inner diameters of 28, 32, and 36mm. The device is implanted by an orthopedic surgeon during hip replacement surgery. It functions as a mechanical interface to facilitate joint articulation, replacing damaged or diseased natural hip joint surfaces. The device is intended to restore joint function and alleviate pain associated with degenerative joint disease, fractures, or previous implant failure.

Clinical Evidence

No clinical data provided as a basis for substantial equivalence. Verification activities were performed on ArComXL™ polyethylene predicate devices, meeting or exceeding current standards.

Technological Characteristics

Acetabular liner composed of ArComXL™ polyethylene. Available in 28mm, 32mm, and 36mm inner diameters. Designed for cemented or non-cemented use in hip arthroplasty. Mechanical device; no software or energy source.

Indications for Use

Indicated for patients requiring total hip arthroplasty due to non-inflammatory 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. For cemented or non-cemented use.

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.

Dear Ms. Koskey:

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
