Intended Use

For Use as a Total Hip Replacement: - Painful disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage vascular necrosis. - Revision of previous cup arthroplasty or other procedures. - Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results. For Use as a Bipolar Hip Replacement - Femoral head/neck fractures or non-unions. - Asceptic necrosis of the femoral head. - Osteo-, rheumatoid, and post traumatic arthritis of the hip with minimal acetabular involvement or distortion. Other Considerations: - Pathological considerations or age considerations which indicate a more conservative acetabular procedure and an avoidance of the use of bone cement in the acetabulum. - Salvage of failed total hip arthroplasty.

Device Story

V40™ Biolox® delta Ceramic Femoral Heads are orthopedic prosthetic components designed for total or bipolar hip replacement. The device serves as the femoral head, mating with V40™ taper femoral stems made of titanium, CoCr, or stainless steel. Manufactured from Zirconia Toughened Alumina (ZTA) ceramic, the heads are available in 28, 32, and 36 mm diameters with various neck offsets. Used in surgical settings by orthopedic surgeons, the device replaces the natural femoral head to restore joint function in patients with degenerative, rheumatoid, or post-traumatic arthritis, or necrosis. The ceramic material provides a bearing surface intended to improve wear characteristics compared to previous alumina versions. Clinical benefit includes pain relief and restoration of hip joint mobility.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Material: Zirconia Toughened Alumina (ZTA) ceramic. Form factor: Femoral head component in 28, 32, 36 mm diameters with V40™ taper interface. Compatibility: Mates with titanium, CoCr, or stainless steel femoral stems. Sterilization: Not specified (identical to predicate).

Indications for Use

Indicated for patients requiring total or bipolar hip replacement due to degenerative, rheumatoid, or post-traumatic arthritis, late-stage vascular necrosis, femoral head/neck fractures, non-unions, or revision of failed arthroplasty. Applicable where conservative acetabular procedures are preferred or arthrodesis is unsuitable.

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.

## Indications for Use

The indications for use of the subject device, in keeping with those of other legally marketed Howmedica Osteonics' ceramic femoral bearing heads are as follows:

## For Use as a Total Hip Replacement:

- Painful disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid . arthritis, post-traumatic arthritis or late stage vascular necrosis.
- Revision of previous cup arthroplasty or other procedures .
- Clinical management problems where arthrodesis or alternative reconstructive techniques are . less likely to achieve satisfactory results.

## For Use as a Bipolar Hip Replacement

- Femoral head/neck fractures or non-unions. .
- Asceptic necrosis of the femoral head. .
- Osteo-, rheumatoid, and post traumatic arthritis of the hip with minimal acetabular . involvement or distortion.

#### Other Considerations:
