Material: High-purity alumina matrix with zirconia reinforcement. Form factor: 22.2mm diameter femoral head with V40 taper. Standards: ISO 7206-10, ISO 7206-13, ASTM F2345-21. Titanium coating on compatible stems tested per ISO 13179-1, ASTM F1160, F1147, F1044, F1978, F1580, F1854. Sterile, single-use.

Indications for Use

Indicated for patients with painful, disabling hip joint disease due to degenerative, rheumatoid, or post-traumatic arthritis, or late-stage avascular necrosis; patients requiring revision of previous unsuccessful hip procedures; patients where arthrodesis or other techniques are unlikely to succeed; and patients with poor bone stock or acetabular deficiencies.

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 Meenakshi Verma/Gregg Ritter:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.

# Intended Use:

The subject device has the same intended use as that specified in the predicate device 510(k) clearance.

# Indications:

The indications for use for the subject device are as follows:

- Painful, disabling joint disease of the hip resulting from: degenerative arthritis, ● rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis.
- Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other . procedure.
- Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.
- Where bone stock is of poor quality or is inadequate for other reconstructive techniques . as indicated by deficiencies of the acetabulum.

# Summary of Technological Characteristics:

The device comparisons and performance testing show that the 22.2mm Biolox® delta Ceramic V40TM Femoral Heads are substantially equivalent to the cited predicate V40™ Biolox® delta Ceramic Femoral Heads cleared via K052718, based on intended use, indications for use, design, material, technological characteristics, operational principles, and non-clinical performance data. The predicate femoral heads are available in an outer diameter of 28mm, 32mm, and 36mm with various neck lengths. The subject femoral heads add two 22.2mm outer diameter options to the existing Biolox® delta Ceramic V40TM Femoral Heads family.
