Device Story

Arcos™ Interlocking Distal Stem is a modular femoral revision implant component; used in femoral revision surgery to replace proximal femur structures. Device features porous-coated Ti-6Al-4V construction; includes interlocking screw holes for temporary rotational stability. Stems available in 15-26mm diameters and 200-300mm lengths; offered in porous cylindrical with proximal taper and splined tapered designs. Implanted by orthopedic surgeons in clinical/OR settings. Provides structural support and fixation for hip reconstruction; benefits patients by restoring joint function and addressing complex femoral bone loss or revision needs.

Clinical Evidence

Bench testing only. Distal pot fatigue testing performed per ISO 7206-8 on six stems to 5 million cycles to verify strength. Torsional fatigue testing performed on Kaessmann Transverse Screws to verify rotational stability. No clinical data provided.

Technological Characteristics

Materials: Ti-6Al-4V (ASTM F-136) for stems/bodies; Ti-6Al-4V (ASTM F-1580) for porous coating. Design: Modular femoral revision system with roller hardened taper and porous plasma spray (PPS®) coating. Dimensions: 15-26mm diameter, 200-300mm length. Application: Uncemented. Fixation: Interlocking screws for rotational stability.

Indications for Use

Indicated for patients requiring hip arthroplasty due to noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures (non-union, femoral neck, trochanteric) unmanageable by other techniques, and for revision of failed total hip arthroplasty.

Regulatory Classification

Identification

A hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis is a two-part 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 includes prostheses that consist of a femoral and an acetabular component, both made of alloys, such as cobalt-chromium-molybdenum. The femoral component is intended to be fixed with bone cement. The acetabular component is intended for use without bone cement (§ 888.3027).

Biomet® Modular Femoral Revision System K090757

#### Device Description:

The Arcos™ Interlocking Distal Stem was designed to be a part of the Arcos™ Modular Femoral Revision System, a modular system using interchangeable stems and proximal bodies commonly seen in femoral revision surgery. The proximal bodies consist of broached, calcar-replacing, and cone-style implants, made from Ti-6Al-4V (ASTM F-136) and featuring a roller hardened taper, is fully porous coated (Ti-6AL-4V, ASTM F-1580) with a fine buffed finish on the bullet-tip. The distal stems will be offered in a range of diameters from 15-26mm and lengths of 200mm, 250mm, and 300mm. The stems are offered in porous cylindrical with proximal taper and splined tapered designs. The stem provides holes for interlocking screws to provide temporary rotational stability. The system also includes auxiliary implants to aid in fixation. The system is intended for uncemented applications

#### Intended Use:

Indications for the Arcos™ Interlocking Distal Stem include:

- 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™ Interlocking Distal Stems are single-use implants, intended for uncemented applications.

### Summary of Technologies:

The Arcos™ Interlocking Distal Stems have the same technological characteristics as the predicates listed above, including the same roller hardened taper process, as well as the same titanium porous plasma spray (PPS®) outer-surface coating.

#### Testing:

The following testing was performed to determine substantial equivalence:

- The distal pot fatique test was performed to verify stem strength in the smallest distal . implant design in the Arcos™ Femoral Revision System. As required in ISO 7206-8, six stems were shown to have sufficient strength to survive distal pot fatigue testing to 5 million cycles. Since the smallest design in the Arcos™ Interlocking Distal Stems product line is a 15mm bullet-tipped stem, the orevious testing of the worst case adequately confirms the strength of the smallest stem within this product line.
- The Kaessmann Transverse Screws, cleared in K9829953, were tested for use with femoral implants . two separate times. The test performed was a torsional fatigue test to determine the ability of the screws to provide temporary rotational stability, as stated in the package insert.
- The results indicated that the device was functional within its intended use.
