Intended Use

The subject Corail Revision Stem is intended for cementless use as part of the femoral component in a total hip arthroplasty.

Device Story

The Corail Revision Stem is a modular, monolithic titanium alloy femoral component for total hip arthroplasty. It features a grit-blasted surface plasma-sprayed with hydroxyapatite. The stem includes a 12/14 AMT (Articul/eze Mini Taper) trunnion, allowing compatibility with previously cleared DePuy femoral heads (metal or ceramic) and acetabular systems. Available in 9 lengths and multiple sizes, the device is implanted by orthopedic surgeons in a clinical/hospital setting. It replaces the femoral head/neck to restore joint function and alleviate pain in patients with degenerative or traumatic hip conditions. The device is intended for cementless fixation.

Clinical Evidence

No clinical testing was required. Substantial equivalence was demonstrated through non-clinical bench testing, including range of motion, proximal fatigue, and ceramic head compatibility testing, alongside characterization of the hydroxyapatite coating.

Technological Characteristics

Monolithic titanium alloy stem; grit-blasted surface; plasma-sprayed hydroxyapatite coating (155 ± 35 microns); 12/14 AMT (Articul/eze Mini Taper) trunnion; available in 9 lengths and sizes 10-20; cementless fixation.

Indications for Use

Indicated for cementless use in patients with severely painful/disabled joints due to osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia; avascular necrosis of the femoral head; acute traumatic fracture of the femoral head or neck; failed previous hip surgery (reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement, or total hip replacement); or ankylosis.

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.

## SUBSTANTIALLY EQUIVALENT DEVICES:

DePuy Corail Hip Stem, K042992 DePuy KAR™ Hip Stem, K961732

## DEVICE DESCRIPTION:

The Corail Revision Stem is part of a modular prosthesis system for use in total hip replacement. It mates with DePuy femoral heads which articulate with DePuy acetabular systems with either a metal or UHMPE liner. The Corail Hip System, Revision Stem is a line addition to the Corail hip stem family. The stems are available in 9 lengths in sizes 10-20 in standard and high-off versions. The subject titanium alloy hip stems are monolithic, grit blasted stems plasma sprayed with hydroxyapatite powders on the entire stem length. The stems feature a 12/14 AMT (Articul/eze Mini Taper) Taper trunnion which are compatible with previously cleared metal and ceramic DePuy femoral heads with corresponding 12/14 tapers and offsets up to +13 mm.

## INDICATIONS AND INTENDED USE:

#### Indications:

The DePuy Corail Revision Stem is indicated for cementless use in the treatment of:

- I. A severely painful and/or a severely disabled joint resulting from osteoarthritis, traumatic arthritis, rheumatoid arthritis or congenital hip dysplasia;
- 2. Avascular necrosis of the femoral head;
- 3. Acute traumatic fracture of the femoral head or neck;
- 4. Failed previous surgery, including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthoplasty, or other total hip replacement; and
- 5. Certain cases of ankylosis.

#### Intended Use:

The subject Corail Revision Stem is intended for cementless use as part of the femoral component in a total hip arthroplasty.

#### Summary of Technologies/Substantial Equivalence:

The substantial equivalence of the subject Corail Revision Stem is demonstrated by similarities in intended use, indications for use, materials, geometry, design and performance as compared to the predicate devices. The changes presented in this 510(k) do not present new issues of safety or effectiveness as the technological characteristics are basically the same as the predicates. Based on the materials, geometry, mechanical testing and indications for use, the DePuy Corail Revision Hip System is considered to be substantially equivalent to the predicate devices.

#### Non-clinical Testing:

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

Non-clinical testing and analysis were provided, including bench testing and coating characterization. Bench testing included Range of Motion, proximal fatigue and ceramic head compatibility testing. The nonporous, calcium phosphate coating was applied by plasma spraying to a nominal thickness of 155 ± 35 microns from hydroxyapatite powders. The calcium phosphate coating is applied by a different vendor and was characterized per FDA's "510(k) Information needed for Hydroxyapatite Coated Orthopedic Implants." All of the observed results indicate that the Corail Revision Hip System is substantially equivalent to devices currently marketed. Therefore, the subject device is as safe, as effective, and performs at least as safely and effectively as legally marketed predicates.

#### Clinical Testing:

No clinical testing was required to demonstrate substantial equivalence.

#### Conclusion:

The subject Corail Revision Stem is substantially equivalent to the predicate devices identified in this premarket notification.
