Intended Use

Components are intended for cemented use and may be used in partial and total hip arthroplasties. The Sirius Femoral Hip Stem is intended for cemented use only and may be used in partial and total hip arthroplasties.

Device Story

Sirius Femoral Stem is a highly polished, double-tapered, cemented hip prosthesis; designed to reduce hip pain and restore joint biomechanics/stability. Features collarless design with rectangular proximal geometry and progressive diminishing distal cross-section. Includes PMMA centralizers for uniform cement mantle. Used in partial or total hip arthroplasties by orthopedic surgeons in clinical settings. Operates on taper-slip principle; taper subsides at stem/cement interface; double-taper engages cement mantle to provide rotational stability and minimize loosening. Available in seven sizes with modular Type 1 taper for head selection. Benefits patient by providing stable femoral fixation in primary or revision hip arthroplasty.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by bench testing including distal and proximal stem fatigue testing (ISO 7206-4:2010, ISO 7206-6:1992, ASTM F2068-09), modular head pull-off testing (ISO 7206-10:2003), range of motion analysis (ISO 21535:2009), and fretting/corrosion testing.

Technological Characteristics

Material: Co-Cr-Mo (ASTM F799). Centralizers: PMMA. Design: Highly polished, double-tapered, collarless, rectangular proximal geometry. Principle: Taper-slip (subsidence at stem/cement interface). Connectivity: None (mechanical implant). Sterilization: Not specified.

Indications for Use

Indicated for patients with non-inflammatory 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, and revision procedures where other treatments failed.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

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

Generation 4 (Gen 4) Polished Femoral Hip System with Proximal Cement Spacer -Biomet-(K052639)

Collarless Polished Taper (CPT) Stem -Zimmer-(K960658)

#### Device Description:

The Sirius femoral stem is a highly polished, double-tapered, cemented stem designed to reduce hip pain for patients and restore ioint biomechanics and stability. The short stem is designed to fit a broad range of patient anatomies for primary or revision cases. The features include a collarless, highly polished, doubletaper design, with a rectangular proximal geometry. The distal portion of the stem has a progressive diminishing cross-section. Each stem is packed with a winged and wingless centralizer, made of polymethylmethacrylate (PMMA), designed to help create a uniform mantle.. The size ranges are within the ranges of legally marketed predicates. The Sirius stem is made from Co-Cr-Mo, ASTM F799.

#### Intended Use:

Components are intended for cemented use and may be used in partial and total hip arthroplasties.

#### Indications for Use:

- Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis. 1.
- Rheumatoid arthritis. 2.
- Correction of functional deformity. 3.
- Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with 4. head involvement, unmanageable by other techniques.
- ട. Revision procedures where other treatment or devices have failed.

The Sirius Femoral Hip Stem is intended for cemented use only and may be used in partial and total hip arthroplasties.

#### Summary of Technologies:

The technological characteristics are the predicates identified in the Legally Marketed Devices to which substantial equivalence is claimed. The design is based on the taper-slip principle: the taper subsides at the stem/cement interface, and the double-taper becomes solidly engaged in the cement mantle. The geometry favors rotational stability to help minimize loosening. The stem is made of Co-Cr-Mo, ASTM F799, as are the predicates, and the centralizers are made of polymethylmethacrylate (PMMA). The Sirius stem is available in seven body sizes with numerous offsets to enable proper sizing and the Type 1 taper enables the choice of numerous modular heads. The Sirius stem features a short length, but the shortest stem in the Sirius system fits within the predicate range of sizes.

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

#### Non-Clinical Testing:

Nonclinical performance testing was performed to support substantial equivalence. The testing included Distal and Proximal Stem fatigue testing of the worst-case stem, consistent with the "Guidance for Industry and FDA Staff Non-clinical Information for Femoral Stem Prostheses", ISO 7206-4:2010, ASTM F2068-09 and ISO 7206-6:1992, Cobalt Chrome Modular Head Pull-off from a Type 1 Reduced Taper, as outlined in ISO 7206-10:2003, as well as a Range of Motion analysis consistent with ISO 21535:2009 and a Comparison/ Justification for Modular Connections, Fretting and Corrosion Testing.

#### Clinical Testing:

None provided as a basis for substantial equivalence.

The results of non-clinical testing demonstrate that the device is as safe, as effective, and performs as well as or better than the predicate devices.
