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 Zirconia Ceramic Femoral Head is designed for single use only.

Device Story

Zirconia Ceramic Femoral Head; prosthetic component for total hip replacement. Designed for use with titanium or cobalt chromium alloy femoral stems via 12/14 taper interface. Implanted by orthopedic surgeons during primary or revision hip surgery. Functions as load-bearing articular surface to restore hip joint function. Single-use device. Benefits patients by replacing damaged femoral head, reducing pain, and restoring mobility in cases of severe joint degeneration or trauma.

Clinical Evidence

Bench testing only. Mechanical testing performed per ceramic femoral head draft guidance requirements demonstrated equivalence to predicate devices and ability to withstand in vivo loading.

Technological Characteristics

Material: Zirconia ceramic. Interface: 12/14 taper. Compatibility: Titanium and cobalt chromium alloy femoral components. Single-use. Mechanical testing performed per ceramic femoral head draft guidance.

Indications for Use

Indicated for individuals undergoing primary and revision hip surgery for 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, 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.

Orthopaedic Division 1450 East Brooks Road Memphis, TN 38116 (901) 396-2121 #### Device Description The Zirconia Ceramic Femoral Head designed for use with both titanium and cobalt chromium alloy femoral components with a 12/14 taper. ### Device Classification Name Device Classification wetal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis Class II #### Indications for 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 Zirconia Ceramic Femoral Head is designed for single use only. ### Mechanical and Clinical Data Mechanical testing was performed according to the requirements in the ceramic femoral head draft guidance document. All of the test results indicate that the Zirconia Ceramic Femoral Head is equivalent to devices currently on the market and capable of withstanding in vivo loading without failure. ## Substantial Equivalence Information The Zirconia Ceramic Femoral Head with a 12/14 taper is similar to the Zirconia Ceramic Femoral Head with a 14/16 taper distributed by Smith & Nephew, Inc. Both heads are indicated for total hip replacement and are similar in design.
