Device Story

Avenir Complete Hip System is a cementless femoral stem prosthesis for total or hemi hip arthroplasty. Device consists of forged Ti-6Al-4V titanium alloy stem with wedge-shaped design, proximal-to-distal taper, and reduced distal geometry. Surface features grit-blasted finish and plasma-sprayed commercially pure titanium (CP-Ti) and hydroxyapatite (HA) coating. Stem connects to femoral heads/adapters via 12/14 male taper. Used by orthopedic surgeons in clinical settings to replace diseased or damaged femoral components. Provides structural support for hip joint, restoring function and mobility. Device is provided sterile for single-use.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by non-clinical bench testing, including finite element analysis, distal/proximal stem fatigue testing, range of motion analysis, pull-off strength, corrosion fatigue, and coating characterization.

Technological Characteristics

Materials: Forged Ti-6Al-4V alloy, CP-Ti and HA plasma-sprayed coating. Design: Wedge-shaped femoral stem, proximal-to-distal taper, 12/14 male taper connection. Fixation: Cementless. Sterilization: Sterile, single-use.

Indications for Use

Indicated for patients requiring total or hemi hip arthroplasty due to degenerative, post-traumatic, or rheumatic joint wear; failed previous hip surgery (osteotomy, arthroplasty, THR); acute traumatic femoral head/neck fracture; or avascular necrosis of the femoral head.

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.

### Purpose and Device Description:

#### Intended Use and Indications for Use:

### Summary of Technological Characteristics:

The purpose of this 510(k) premarket notification is to introduce two Size 0 Coxa Vara Avenir Complete™ Hip System femoral stems; one with a collar and one without a collar. The stems are manufactured from a forged titanium alloy Ti-6Al-4V and feature a wedge-shaped design with a proximal-to-distal taper and reduced distal geometry. The Coxa Vara offset provides a 126.5° neck angle. Below the highly polished femoral neck region, the surface is gritblasted and plasma sprayed with commercially pure titanium (CP-Ti) and hydroxyapatite (HA) coating. The stems are designed for cementless implantation into the proximal femur and mates with compatible femoral heads and adapters for use in total or hemi hip arthroplasty through a 12/14 male taper connection. The stems are provided sterile and are for single-use only.

Avenir Complete™ Hip System is intended for total or hemi hip arthroplasty and is indicated for the following conditions:

- Advanced wear of the joint due to degenerative, post-● traumatic or rheumatic diseases.
- Failed previous hip surgery including joint . reconstruction (osteotomy), arthrodesis, hemiarthroplasty or total hip replacement (THR).
- Acute traumatic fracture of the femoral head or neck. ●
- Avascular necrosis of the femoral head.

Avenir Complete™ Hip System is for cementless use only.

The rationale for substantial equivalence is based on consideration of the following characteristics:

- Intended Use: Identical to the predicate device. ●
- Indications for Use: Identical to the predicate device. .
- Design Features: The proposed and predicate devices . incorporate the same design features and fundamental scientific technology. Both stems mate with a variety of femoral heads and adapters equipped with 12/14 tapered necks. The stem length, femoral offset, and collared geometry are features existing in the predicate device.
- Fixation Method: Identical to the predicate device.
- . Materials: The proposed and predicate devices are manufactured from Ti-6A1-4V alloy and plasma

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

sprayed with commercially pure titanium (CP-Ti) and hydroxyapatite (HA) using the same manufacturing processes.

- . Sterilization Method: Identical to the predicate device.
## Summary of Performance Data (Nonclinical and/or Clinical)

## Non-Clinical Testing:

Non-clinical performance testing and engineering evaluations were conducted to verify that the performance of the proposed device is adequate for anticipated in-vivo use. Non-clinical testing carried out on the proposed device include distal stem fatigue testing and proximal stem fatigue testing. Testing demonstrated that the proposed device is not a new worst-case for proximal stem fatigue testing but presents a greater challenge to distal stem fatigue testing than the previously evaluated predicate Avenir Complete™ Hip System range (K182048). Nevertheless, the proposed device was determined to have a distal stem fatigue strength equivalent to the legally marketed reference device (K120030).

The following non-clinical testing is provided in this 510(k) to support substantial equivalence determination of the proposed device to the predicate device in terms of safety and performance:

- 1. Finite Element Analysis to identify the worst-case stem size for the mechanical fatigue testing
- 2. Distal Stem Fatigue Testing
- 3. Proximal Stem Fatigue Testing
- 4. Range of Motion Analysis
- 5. Pull-Off Strength Evaluation
- 6. Corrosion Fatigue Evaluation
- 7. Ti/HA Coating Characterization Evaluation
- 8. Magnetic Resonance Imaging Compatibility (MRI)

# Clinical Testing:

Clinical data and conclusions were not needed for this device.

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

## Substantial Equivalence Conclusion

The proposed device has the same intended use and indications for use as the predicate device. The proposed device uses the same operating principle, incorporates the same design and materials, and is manufactured and sterilized using the same manufacturing processes as the predicate device. Technological characteristics of the proposed device are the same as the predicate device and similar to the reference device, and the performance data and analyses demonstrate that:

- any differences do not raise new questions of safety . and effectiveness as established with performance testing; and
- . the proposed device is at least as safe and effective as the legally marketed predicate device.
