Intended Use

The INTRAPLANT Ceramic Head Prostheses is intended for use in total hip arthroplasty. The indications for use of the total hip replacement prosthesis include: degenerative joint disease including osteoarthritis and avascular necrosis; rheumatoid arthritis; correction of functional deformity; revision procedure where previous treatments or devices have failed; and treatment of nonunion, femoral neck and trochanteric fractures of the proximal femur with head involvement, which is unmanageable using other techniques. The INTRAPLANT Ceramic Head Prostheses are to be used only with SL-PLUS® and SLR-PLUS® hip stems.

Device Story

INTRAPLANT Ceramic Head Prostheses are orthopedic implants used in total hip arthroplasty. Manufactured from alumina and zirconia, these femoral heads are designed to interface with specific hip stems (SL-PLUS and SLR-PLUS). The device replaces the femoral head in the hip joint to restore function and mobility in patients with degenerative joint disease, arthritis, or fractures. Used in surgical settings by orthopedic surgeons. The device provides a bearing surface for the hip joint, aiming to reduce pain and improve joint function. Biomechanical testing confirms structural integrity for its intended orthopedic application.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: Alumina and zirconia ceramic. Form factor: Femoral head with standard 12/14 taper cone. Sizes: 28mm (S, M, L) and 32mm (S, M, L). Compatibility: Restricted to SL-PLUS and SLR-PLUS hip stems.

Indications for Use

Indicated for patients requiring total hip arthroplasty due to degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, revision of failed prior procedures, or nonunion/fractures of the proximal femur. Contraindicated in patients with active/chronic infection, severe muscular/neurological/vascular deficiency, insufficient bone quality, severe obesity, material allergy, subluxation, ligament instability, or severe varus/valgus misalignment.

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. Loch:

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 Regulation (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.
