Intended Use

Total hip components are individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory ioint 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; nonunion; femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; femoral osteotomy, or Girdlestone resection; fracture dislocation of the hip; and correction of deformity. The subject devices are intended for single use only.

Device Story

10/12 Taper Oxinium Femoral Heads are orthopedic prosthetic components for total hip replacement. Manufactured from oxidized zirconium; designed to interface with 10/12 taper femoral stems. Device sizes include 22 mm (offsets -3, 0, +3 mm) and 26-36 mm (offsets -5, 0, +5 mm). Used by orthopedic surgeons in clinical settings during primary or revision hip arthroplasty. Provides a bearing surface to restore hip joint function in patients with degenerative or traumatic hip conditions. Benefits include improved wear performance and corrosion resistance compared to traditional metal heads. Device is single-use.

Clinical Evidence

Bench testing only. Performance evaluated via pre-fatigue and post-fatigue assembly/disassembly, environmental fatigue and corrosion, axial fatigue, range of motion, device rigidity, and wear performance. Results demonstrate equivalence to predicate devices.

Technological Characteristics

Material: Oxidized zirconium. Form factor: Femoral head with 10/12 taper interface. Sizes: 22 mm (offsets -3, 0, +3 mm) and 26-36 mm (offsets -5, 0, +5 mm). Mechanical device; no energy source or software.

Indications for Use

Indicated for individuals undergoing primary or revision hip surgery 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, nonunion, femoral neck/trochanteric fractures, femoral osteotomy, Girdlestone resection, fracture dislocation, or deformity).

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.

### Device Description

Subject of this Traditional 510(k) Premarket Notification are the Smith & Nephew, Inc. 10/12 Taper Oxinium Femoral Heads. The subject devices are geometrically similar to the femoral head component in the Echelon Titanium Hip System cleared via submission K072817 and will include the addition of 32 mm and 36 mm diameter head sizes. This premarket notification seeks to add the 10/12 taper femoral head in oxidized zirconium material. Oxidized zirconium is the material of manufacture for 12/14 taper Femoral Heads cleared via submission K021673. The subject device will be offered in a size of 22 mm with offsets of -3, +0, and +3 mm; and is sizes ranging from 26 mm - 36mm, all with offsets of -5, +0, and +5 mm.

#### Intended Use

Total hip components are individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma, inflammatory ioint 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; nonunion; femoral neck fracture and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; femoral osteotomy, or Girdlestone resection; fracture dislocation of the hip; and correction of deformity. The subject devices are intended for single use only.

#### Performance Data

Performance testing of the 10/12 taper Oxinium Femoral Heads yields results at least equivalent to previously cleared devices, Total Hip Femoral head - 12/14 Taper, submission K021673; and Echelon Titanium Hip System, submission K072817. Results of testing and analysis show that the subject device performs equal to or better than previously cleared devices in regards to:
