Intended Use

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 or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, fracture of the pelvis, and diastrophic variant. Hip components are also indicated for inflammatory degenerative joint disease including rheumatoid arthritis, arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia; treatments of nonunion, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; endoprosthesis, femoral osteotomy, or Girdlestone resection; fracture-dislocation of the hip; and correction of deformity. The ANTHOLOGY AFIT Hip Stem is for single use only. The ANTHOLOGY AFJT Hip Stem is intended for cementless use.

Device Story

ANTHOLOGY AFIT Hip Stem is a femoral component for hip arthroplasty; intended for cementless fixation in primary or revision surgery. Device serves as a structural replacement for damaged femoral head/neck. Implanted by orthopedic surgeons in clinical/OR settings. Provides mechanical stability for hip joint; facilitates patient mobility and pain relief. Manufactured from titanium alloy; features porous and hydroxyapatite coatings for osseointegration. Available in multiple sizes with high/standard neck offsets.

Clinical Evidence

No clinical data provided. Safety and effectiveness supported by mechanical testing and comparison to predicate device.

Technological Characteristics

Titanium alloy (Ti-6Al-4V) per ASTM F1472. Proximal body: porous-coated (ASTM F67) and hydroxyapatite-coated. Middle section: grit-blasted. Distal end: glass-beaded. 12/14 taper. Sizes 3-14. Cementless fixation. Pyrogen limit <= 20 EU/device.

Indications for Use

Indicated for individuals undergoing primary/revision hip surgery due to trauma, noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, pelvic fracture, diastrophic variant), inflammatory degenerative joint disease (rheumatoid arthritis, congenital dysplasia), nonunion, femoral neck/trochanteric fractures, or deformity correction. For cementless use.

Regulatory Classification

Identification

A hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.

#### Device Description

Subject of this Special premarket notification is the addition of a new stem design to the Smith & Nephew ANTHOLOGY™ Hip System. The ANTHOLOGY Hip System currently consists of the ANTHOLOGY Hip Stems cleared via premarket notification K052792. The proposed devices are ANTHOLOGY™ AFIT Hip Stems, new hip stems that will be marketed as part of the ANTHOLOGY Hip System.

The ANTHOLOGY AFIT Hip Stem represents minor design modifications when compared to the predicate ANTHOLOGY Hip Stem cleared via K052792. The ANTHOLOGY AFIT Hip Stem is manufactured from Titanium alloy (Ti-6Al-4V) per ASTM F1472. The proximal body is both porous-coated per ASTM F67 and hydroxyapatite-coated, the middle section is grit-blasted, and the distal end is glassbeaded. The ANTHOLOGY AFIT Hip Stem will be available in a size range of 3 to 14, in both a high and standard neck offset with a 12/14 taper.

#### Intended Use

Hip components are indicated for individuals underqoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of trauma or noninflammatory degenerative joint disease (NIDJD) or any of its composite diagnoses of osteoarthritis, avascular necrosis, traumatic arthritis, slipped capital epiphysis, fused hip, fracture of the pelvis, and diastrophic variant.

Hip components are also indicated for inflammatory degenerative joint disease including rheumatoid arthritis, arthritis secondary to a variety of diseases and anomalies, and congenital dysplasia; treatments of nonunion, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques; endoprosthesis, femoral osteotomy, or Girdlestone resection; fracture-dislocation of the hip; and correction of deformity.

{4}------------------------------------------------

The ANTHOLOGY AFIT Hip Stem is for single use only. The ANTHOLOGY AFJT Hip Stem is intended for cementless use.

## Technological Characteristics

A review of the existing ANTHOLOGY Hip Stem testing has demonstrated that there are no new issues related to the safety and effectiveness of the subject devices. Clinical data was not needed to support the safety and effectiveness of the subject devices.

"The Limulus Amebocyte Lysate (LAL) test was used to determine the subject devices meets the specified pyrogen limit specification of less than or equal to 20 EU/device."

### Substantial Equivalence Information

The subject devices are identical in function, intended use, indications for use, material composition, and very similar in overall design to the ANTHOLOGY Hip Stem cleared via premarket notification K052792.

#### Table 1: Substantially Equivalent Predicate to the ANTHOLOGY AFIT Hip Stem

| Manufacturer | Description | Submission<br>Number | Clearance Date |
