Intended Use

Total hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory joint disease such as rheumatoid arthritis, or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses such as osteoarthritis; avascular necrosis; traumatic arthritis; slipped capital epiphysis; fused hip; fracture of the pelvis; diastrophic variant; old, remote osteomyelitis with an extended drainage-free period; nonunion; femoral neck fracture and trochanteric fractures of the proximal femur with heads involvement that are unmanageable using other techniques; femoral osteotomy, or Girdlestone resection; fracture dislocation of the hip; and correction of deformity. The 28 mm. long Biolox Alumina Ceramic Femoral Head is designed for single use only.

Device Story

The 28 mm Biolox Alumina Ceramic Femoral Head is a prosthetic component for total hip replacement. Manufactured from aluminum oxide (Al2O3), it is designed to interface with titanium or cobalt-chromium femoral stems via a 12/14 taper. The device is intended for single-use during primary or revision hip surgery. It functions as a load-bearing articulating surface within the hip joint. Surgeons implant the device to restore joint function in patients with degenerative or traumatic hip conditions. The ceramic material provides wear resistance and structural integrity under in vivo loading conditions.

Clinical Evidence

Bench testing only. Mechanical testing was conducted in accordance with the ceramic femoral head draft guidance document. Results demonstrate the device is equivalent to predicate devices and capable of withstanding in vivo loading without failure. No clinical data provided.

Technological Characteristics

Material: Aluminum oxide (Al2O3). Interface: 12/14 taper. Form factor: 28 mm femoral head. Compatibility: Titanium and cobalt-chromium alloy femoral components. Sterilization: Not specified. Energy source: None (mechanical).

Indications for Use

Indicated for patients undergoing primary or revision total hip arthroplasty due to trauma, inflammatory joint disease (e.g., rheumatoid arthritis), or noninflammatory degenerative joint disease (e.g., osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, pelvic fracture, diastrophic variant, remote osteomyelitis, nonunion, femoral neck/trochanteric fractures, femoral osteotomy, Girdlestone resection, fracture dislocation, or deformity correction).

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.

#### Subject device description:

The 28 mm. long Biolox Alumina Ceramic Femoral Head is manufactured from aluminum oxide (Al2O3), and it is designed for use with both titanium and cobalt chromium alloy femoral components with a 12/14 taper.

#### Subject device intended use:

Total hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory joint disease such as theumatoid arthritis, or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses such as osteoarthritis; avascular necrosis; traumatic arthritis; slipped capital epiphysis; fused hip; fracture of the pelvis; diastrophic variant; old, remote osteomyelitis with an extended drainage-free period; nonunion; femoral neck fracture and trochanteric fractures of the proximal femur with heads involvement that are unmanageable using other techniques; femoral osteotomy, or Girdlestone resection; fracture dislocation of the hip; and correction of deformity.

The 28 mm. long Biolox Alumina Ceramic Femoral Head is designed for single use only.

#### Technological characteristics:

The 28 mm. long Biolox Alumina Ceramic Femoral Head with a 12/14 taper is similar to the devices listed below.

- . Biolox Alumina Ceramic Femoral Head - Smith & Nephew
- Zirconia Ceramic Femoral Head Smith & Nephew �
- . Alumina C - Taper Ceramic Femoral Head - Osteonics

All of the devices listed above are indicated for total hip replacement and are similar in design to the 28 mm. long Biolox Alumina Ceramic Femoral Head. The new device has the same technological characteristics as the predicate device.

#### Performance characteristics:

Mechanical testing was performed according to the requirements in the ceramic femoral head draft guidance document. All of the test results indicate that the 28 mm. long Biolox Alumina Ceramic Femoral Head is equivalent to devices currently on the market and capable of withstanding in wivo loading without failure.
