• Attributes: Therapeutic

Intended Use

1. Fractures of the proximal femur 2. Non-unions of proximal femoral neck fractures. 3. Aseptic necrosis of the femoral head: 4. Osteo-rheumatoid and post-traumatic arthritis of the hip with minimal distortion of the acetabulum. 5. Salvage of failed total hip arthroplasty.

Device Story

SkelKast Bipolar System is a prosthetic hip implant designed for surgical replacement of the femoral head. Used by orthopedic surgeons in hospital settings to treat degenerative or traumatic hip conditions. Device functions as a mechanical replacement for the natural femoral head, articulating within the patient's acetabulum or a prosthetic cup. Benefits include restoration of hip joint function and mobility for patients with severe hip pathology.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Bipolar hip prosthesis system. Mechanical device; no software or electronic components. Materials and sterilization methods are consistent with standard orthopedic implant requirements.

Indications for Use

Indicated for patients requiring hip arthroplasty due to proximal femur fractures, non-unions of femoral neck fractures, aseptic necrosis of the femoral head, osteo-rheumatoid or post-traumatic arthritis with minimal acetabular distortion, or salvage of failed total hip arthroplasty.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Dear Mr. Stevens:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
