Intended Use

The Initia Total Hip System is a single use total hip system for use in cementless hip arthroplasty procedures for the following indications: - Painful disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis, - Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure, - Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results, The Initia Total Hip System femoral stems are intended for cementless press-fit use. The Initia Total Hip System acetabular shells are intended for cementless use with biological fixation. The BIOCERAM AZUL HEAD is a single use modular femoral head component for use in hip arthroplasty procedures for the following indications: - Painful disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis, - Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure, - Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.

Device Story

Initia Total Hip System and BIOCERAM AZUL HEAD are modular hip arthroplasty components. System includes femoral stems (titanium alloy, plasma-sprayed), acetabular shells (titanium alloy, plasma-sprayed), crosslinked UHMWPE liners, Co-Cr femoral heads, and ZTA ceramic heads. Components are implanted by orthopedic surgeons in clinical settings to replace diseased hip joints. Femoral stems are press-fit; acetabular shells rely on biological fixation. Modular heads attach via 12/14 taper. Device restores joint function, reduces pain, and improves mobility for patients with degenerative or post-traumatic hip conditions.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing including femoral stem/neck fatigue, taper pull-off, fretting corrosion, acetabular shell/liner push-out/lever-out/torque-out, hip simulator wear (including Mode 3), wear particle analysis, impingement, and bone screw mechanical testing. Coating characterization and biocompatibility testing were also performed.

Technological Characteristics

Materials: Titanium alloy (ASTM F136, F620), plasma-sprayed CP titanium (ASTM F1580), Co-Cr (ASTM F1537), crosslinked UHMWPE (ASTM F648, F2565), ZTA ceramic (ISO 6474-2). Design: Modular, cementless, press-fit femoral stems; acetabular shells with locking liners; 12/14 taper interface. Sterilization: Not specified.

Indications for Use

Indicated for patients with painful disabling hip joint disease (degenerative, rheumatoid, post-traumatic arthritis, or late-stage avascular necrosis), patients requiring revision of previous unsuccessful hip procedures, or patients where arthrodesis/alternative reconstruction is unlikely to succeed.

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.

## DEVICE DESCRIPTION:

The Initia Total Hip System is comprised of femoral stems, Co-Cr femoral heads, acetabular shells, an apical hole plug, bone screws and crosslinked polyethylene acetabular liners.

The BIOCERAM AZUL® ceramic heads are zirconia toughened alumina (ZTA) ceramic femoral heads compatible with the femoral stems, acetabular shells and acetabular liners of the Initia Total Hip System.

The femoral stem is a monoblock wedge tapered design. It is manufactured from forged titanium alloy complying with ASTM F136 and ASTM F620 and is coated with a plasma spray of commercially pure titanium complying with ASTM F1580. The stem is offered in 19 stem sizes which include both standard and high offset neck options, for a total of 38 offerings.

The Co-Cr femoral head is manufactured from wrought Co-Cr complying with ASTM F1537. The head has a 12/14 taper bore and is available in outer diameters of 22, 26, 28, 32, 36, 40 and 44 mm. Each head diameter is available in multiple offset options.

The acetabular shell is also made from titanium alloy complying with ASTM F136. The acetabular shell is available in outer diameters ranging from 40 mm to 74 mm in 2 mm increments. The outer surface of the shell is coated with a plasma spray of commercially pure titanium complying with ASTM F1580. The acetabular shell is offered in 0 hole, 3 hole, and multi-hole configurations. Self-tapping acetabular bone screws can be used for initial shell

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

fixation. The screws are made from titanium alloy complying with ASTM F136. Bone screws are available in a 6.5 mm diameter and lengths from 15 to 60 mm in 5 mm increments. An apical hole plug, manufactured from titanium alloy complying with ASTM F136, is available to close the apical hole on the acetabular shell.

The acetabular liner is made from crosslinked ultra high molecular weight polyethylene (UHMWPE) complying with ASTM F648 and ASTM F2565. The polyethylene liner is offered in inner diameters of 22, 26, 28, 32, 36, 40 and 44 mm with outer diameters to fit the 40 - 74 mm acetabular shells. The liner is offered in 4 configurations: standard (STD), standard with offset (STD HO), elevated rim (MX), and elevated rim with offset (MX HO). The liner mates with the shell using a circumferential locking feature that is integrated into the liner to prevent disassociation. The locking feature mates with a circular groove machined into the shell. The liner also possesses anti-rotation tabs that mate with scallops in the shell.

The BIOCERAM AZUL® ceramic head is manufactured from high purity alumina matrix with zirconia reinforcement, which complies with ISO 6474-2. The head has a 12/14 taper bore and is available in outer diameters of 28, 32, 36, 40 and 44 mm. There are 3 offsets (-3.5, +0, +3.5 mm) for the 28 mm size. There are 4 offsets (-3.5, +0, +3.5, +7 mm) for the 32 to 44 mm sizes.

{7}------------------------------------------------

- Painful disabling joint disease of the hip resulting from: degenerative arthritis, rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis,
- Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other procedure,
- Clinical management problems where arthrodesis or alternative reconstructive techniques are less likely to achieve satisfactory results.

## BASIS FOR SUBSTANTIAL EQUIVALENCE:

The Initia Total Hip System and the BIOCERAM AZUL® ceramic heads are substantially equivalent to the predicate devices based on similarities in intended use, indications for use, materials, design, sizing and mechanical strength.

## PERFORMANCE DATA:

Mechanical testing confirmed that the Initia Total Hip System met pre-determined acceptance criteria for femoral stem neck fatigue, femoral stem fatigue, Co-Cr femoral head / femoral stem taper axial pull-off, fretting corrosion, acetabular shell / acetabular liner push-out, lever-out and torque-out, hip simulator wear, Mode 3 (with a roughened femoral head) hip simulator wear, wear particle analyses, impingement, bone screw torsional strength, insertion and removal torque and pull-out, and total hip range of motion.

Characterization testing included femoral stem and acetabular shell coating characterization and performance testing (static shear, static tensile, shear fatigue, abrasion resistance), and characterization of the crosslinked UHMWPE liner material in aged and unaged conditions as compared to predicate devices.

Biocompatibility testing was also conducted. Bacterial Endotoxin Testing was performed and the endotoxin limit of 20EU/device was met.

The BIOCERAM AZUL® ceramic heads met pre-determined acceptance criteria for static burst strength, fatigue, post-fatigue burst strength, axial pull-off, fretting corrosion, hip simulator wear, Mode 3 (with a roughened ceramic head) hip simulator wear and wear particle analyses.

## CLINICAL TESTING:

Clinical testing was not required for determining substantial equivalence with the predicate devices.
