Intended Use
The Headloc™ Ceramic Femoral Head for the Primaloc™ Cementless Hip System is intended for single-use cementless implantation during primary revision surgery. The Ceramic Head allows for primary articulation between the acetabular cup and femoral stem to restore patient mobility. Indications for use are: - Osteoarthritis, rheumatoid arthritis, or other osteoarthroses; - Certain femoral neck fractures or dislocations; - Post-traumatic arthritis; - Idiopathic avascular necrosis of the femoral head; - Benign or malignant bone tumors where sufficient bone stock exists to seat the prosthesis; - Previous failed surgery; - Total hip replacement where the surgeon indicates a ceramic head
Device Story
Headloc™ Ceramic Femoral Head is a prosthetic component for total hip replacement. It serves as the articulating surface between an acetabular cup and a femoral stem. Used in primary or revision surgery to restore patient mobility. Implanted by orthopedic surgeons in an operating room setting. Device must be used exclusively with Ti6Al4V alloy hip stems featuring a specific CeramTec 5°42'30" (+0', -5') cone angle. Benefits include restoration of joint function and mobility in patients with degenerative or traumatic hip conditions.
Clinical Evidence
No clinical data provided; bench testing only.
Technological Characteristics
Ceramic femoral head component. Designed for cementless implantation. Material: Ceramic. Compatibility: Restricted to Ti6Al4V alloy hip stems with a specific CeramTec 5°42'30" (+0', -5') cone angle.
Indications for Use
Indicated for patients requiring total hip replacement due to osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, idiopathic avascular necrosis, femoral neck fractures/dislocations, bone tumors, or previous failed surgery. Requires sufficient bone stock for prosthesis seating.
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 Ms. Freasier:
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 and the following limitation that the package insert must reflect that the Headloc™ Ceramic Femoral Heads are to be used only with Ti6Al4V alloy hip stems with the CeramTec 5°42'30" (+0', -5') cone angle.
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 Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that,
{1}
Page 2 - Ms. Carol Freasier
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.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification immediately. An FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for *in vitro* diagnostic devices), please contact the Office of Compliance at (301) 594-4659. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrh/dsmamain.html".
