Indications for Use

The Arcos Trochanteric Button is intended for use with the Arcos Modular Femoral Revision System, which is cleared only for uncemented use (K090757), as well as the Arcos Interlocking Stems, a line extension to the Arcos Modular Femoral Revision System, added by Special 510(k) K 100469, listed in the compatible component section.

Device Story

Arcos Trochanteric Button is a hip prosthesis accessory designed to provide proximal stability during hip revision surgery, particularly following greater trochanteric osteotomy. It functions as a washer to compress the greater trochanter against the femoral prosthesis or to assist in reattachment. Used in clinical settings by orthopedic surgeons during total hip arthroplasty or revision procedures. The device provides mechanical fixation, aiding in bone healing and structural restoration of the proximal femur. It serves as an alternative to the claw mechanism for trochanteric fixation.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, specifically Finite Element Analysis (FEA) for pull-through comparison and cross-section analysis.

Technological Characteristics

Manufactured from Ti-6Al-4V. Designed as a single-size trochanteric button/washer for use with the Arcos Modular Femoral Revision System. Mechanical fixation principle. Uncemented application. No software or electronic components.

Indications for Use

Indicated for patients with noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, non-union, femoral neck fracture, trochanteric fractures of the proximal femur with head involvement unmanageable by other techniques, or revision of failed total hip arthroplasty. Intended for single-use, uncemented applications.

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.

#### Legally Marketed Devices To Which Substantial Equivalence Is Claimed:

The predicate device is the Biomet Modular Femoral Revision Modular System (Arcos), K090757.

#### Device Description:

The Arcos Trochanteric Button is being added to the Arcos Modular Femoral Revision System, K090757, to expand surgical options beyond the claw when increased proximal stability is needed, especially when a greater trochanteric osteotomy has been performed. This assembly allows the greater trochanter to be compressed against the prosthesis or for reattaching the greater trochanter in cases where a trochanteric osteotomy has been performed. The Trochanteric Button comes in one size and is manufactured from Ti-6Al-4V. The design is very similar to the cleared Trochanteric Plate cleared for use with the Mallory-Head Modular Calcar System, K031693.

{2}------------------------------------------------

#### Intended Use:

The Arcos Trochanteric Button is intended for use with the Arcos Modular Femoral Revision System, which is cleared only for uncemented use (K090757), as well as the Arcos Interlocking Stems, a line extension to the Arcos Modular Femoral Revision System, added by Special 510(k) K 100469, listed in the compatible component section.

#### Indications For Use:

- 1. Noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis.
- 2. Rheumatoid arthritis.
- 3. Correction of functional deformity.
- 4. Treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques.
- 5. Revision of previously failed total hip arthroplasty.

The Arcos Modular Femoral Revision System Trochanteric Button hip components are singleuse implants, intended for uncemented applications.

#### Summary of Technologies:

The Arcos Trochanteric Button is being added to the line of accessories for use with the Arcos Modular Femoral Revision System. The Arcos Trochanteric Button uses the same technology as the referenced previously cleared Trochanter Plate included in the Revision Mallory-Head Modular Calcar with and without HA, K031693, which served as a predicate for the Arcos Modular Femoral Revision System. The subject device is manufactured from the same material, conforming to the same standard, as the previously cleared Trochanter Plate.

#### Non-Clinical Testing:

- · Pull-Through Comparison (FEA)
- · Cross Section Analysis

Since the stresses are reduced on the new washer due to the smaller hole and larger contact area, the proposed Arcos Modular Femoral Revision System Trochanteric Button should perform as well or better than the referenced cleared Mallory-Head® Trochanter Plate, thus meeting the acceptance criteria, indicating capability to fulfill surgical expectations.

#### Clinical Testing:

None provided as a basis for substantial equivalence.

Testing and analysis demonstrates that the modifications made to the Arcos Modular Femoral Revision System, by the addition of the Arcos Trochanteric Button, do not introduce any new risks of safety or efficacy.
