Intended Use

The Klassic HD™ Hip System is intended for prosthetic replacement without bone cement in treatment of the following: - . Patient conditions of non-inflammatory degenerative joint disease (NIDJD): avascular necrosis, osteoarthritis, ankylosis, protrusio acetabuli and painful hip dysplasia. - Patient conditions of inflammatory joint disease (IJD): rheumatoid arthritis. ● - Those patients with failed previous surgery where pain, deformity, or dysfunction ● persists. - Revision of a previously failed hip arthroplasty. - Patients who require a total hip replacement.

Device Story

Klassic HD™ Hip System; prosthetic hip replacement device; restores hip joint biomechanics by addressing femur/acetabulum size, leg length, offset, and version. System components include femoral stems, acetabular components, and femoral heads. Modification adds ceramic femoral heads to existing system; compatible with metal (CoCrMo) or ceramic femoral heads and UHMWPE acetabular components. Used by surgeons in clinical/OR settings for total hip arthroplasty. Device provides mechanical structural support for hip joint; intended for non-cemented use. Benefits include pain relief and restoration of joint function for patients with degenerative or inflammatory joint disease.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included burst strength, fatigue, post-fatigue burst strength, and pull-off testing of ceramic femoral heads to verify mechanical integrity.

Technological Characteristics

Semi-constrained hip prosthesis; non-cemented. Materials: Ceramic femoral heads, metal (CoCrMo) femoral heads, UHMWPE acetabular components. Modular design allows independent adjustment of femur/acetabulum size, leg length, offset, and version.

Indications for Use

Indicated for patients requiring total hip replacement due to non-inflammatory degenerative joint disease (avascular necrosis, osteoarthritis, ankylosis, protrusio acetabuli, painful hip dysplasia), inflammatory joint disease (rheumatoid arthritis), failed previous surgery, or revision of failed hip arthroplasty.

Regulatory Classification

Identification

A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

Dear Mr. Weaber:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

## Device Description:

The Klassic HD™ Hip System employs a prosthesis designed to help surgeons restore hip joint biomechanics intraoperatively by independently addressing the size of the femur and acetabulum, leg length, offset and version. The Klassic HD™ Hip System can be mated with metal (CoCrMo) or ceramic femoral heads and UHMWPE acetabular components.

## Predicate Devices:

The modified Klassic HD™ Hip System is substantially equivalent to the predicate Klassic HD™ Hip System (K100445) with respect to indications, design, and function.

## Substantial Equivalence:

The company performed burst strength testing, fatigue testing, post-fatigue burst strength testing and pull-off testing of the ceramic femoral heads. The test results demonstrate that the pre-determined acceptance criteria identified in the Design Control Activities Summary were met.

## Conclusion

The Klassic HD™ Hip System when mated with a ceramic femoral head is substantially equivalent to previously cleared devices with respect to its indications for use, design, and function.
