Intended Use

The Responsive Orthopedics Total Hip Arthroplasty System is indicated for cementless use only in the following cases: - Noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis; - Rheumatoid arthritis; - Correction of functional deformity; - Revision procedures where other treatments or devices have failed; and - Nonunions, femoral neck and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques. The Responsive Orthopedics Total Hip Arthroplasty System Acetabular screws are indicated for supplemental fixation of Responsive Orthopedics Acetabular Cup.

Device Story

Total hip arthroplasty system replacing articulating hip joint surfaces to restore alignment, stability, and range of motion while alleviating pain. System comprises femoral stems, acetabular cups, acetabular liners, and femoral heads. Used in surgical settings by orthopedic surgeons. Implants available in multiple sizes to match patient anatomy. Acetabular screws provide supplemental fixation for acetabular cups. Device functions as a semi-constrained prosthesis; restores joint mechanics through mechanical replacement of bone/cartilage structures. Benefits include improved mobility and pain reduction for patients with degenerative or traumatic hip conditions.

Clinical Evidence

Bench testing only. Performed femoral stem/neck fatigue, axial/cup/liner disassembly, fretting/corrosion, screw characteristics, and ceramic head burst/torque/fatigue testing. Wear/impingement performance addressed via comparative analysis of liner thickness against predicates. All tests met acceptance criteria.

Technological Characteristics

Materials: Ti-6Al-4V ELI (ASTM F136/F620), Co-Cr-Mo alloy (ASTM F1537), BIOLOX delta ceramic, and conventional non-crosslinked GUR1020 UHMWPE (ASTM F648). Semi-constrained hip prosthesis. Cementless fixation. Porous structure characterization referenced in MAF-628.

Indications for Use

Indicated for patients requiring cementless total hip arthroplasty due to noninflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, failed prior procedures, or proximal femur fractures/nonunions unmanageable by other techniques.

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.

The predicate and subject devices have the same function.

#### VI. Materials

{5}------------------------------------------------

The RO THA Femoral Stems and acetabular cups are manufactured from forged Ti-6AI-4V ELI conforming to ASTM F136 and ASTM F620.

The RO THA Acetabular Screws are manufactured from machined Ti-6AL-4V ELI conforming to ASTM F136.

The RO THA Femoral heads are manufactured from Co-Cr-Mo alloy conforming to ASTM F1537 and from BIOLOX® delta.

The RO THA Acetabular Liners are manufactured from conventional, noncrosslinked GUR1020 UHMWPE conforming to ASTM F648.

#### VII. Performance Data

The following performance bench testing was performed for the Responsive Orthopedics Total Hip Arthroplasty System in support of the substantial equivalence determination.

The tests completed were:

- -Femoral Stem Fatigue Testing
- Femoral Neck Fatigue Testing -
- Axial Disassembly Testing -
- -Fretting and Corrosion Testing
- -Cup and Liner Disassembly Testing
- Screw Characteristics Testing -
- Ceramic Femoral Head Comparative Burst Testing -
- Ceramic Femoral Head Fatigue and Post-Fatigue Burst Testing -
- Ceramic Femoral Head Axial Disassembly Testing -
- Ceramic Femoral Head Torque Testing -
- -Pyrogenicity Testing

Wear and impingement performance of the conventional, non-crosslinked polyethylene liners in the subject system were addressed based on a comparison of the minimum thickness in the rim and load-bearing regions of the liners with the predicate devices.

All tests which are in relation to the porous structure characterization (physical, chemical or mechanical) are in Master File MAF - 628 (owned by APS Materials) and are not included in this 510(k).

The subject devices met the pre-determined acceptance criteria for all tests. Therefore, design verification testing determined that the subject devices are substantially equivalent to the predicate devices.

#### VIII. Conclusions

{6}------------------------------------------------

Based on the test results and additional supporting information provided in this pre-market notification, the subject devices demonstrated substantial equivalence to the legally marketed predicate devices.
