Intended Use

The Trinity Acetabular System is intended for use in total hip arthroplasty in skeletally mature patients, to provide increased mobility and reduce pain by replacing the damaged hip joint articulation where there is evidence of sufficient sound bone to seat and support the components. The indications for the Trinity Acetabular System as a total hip arthroplasty include: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis - Rheumatoid arthritis - Correction of functional deformity - Developmental dysplasia of the hip (DDH) or congenital dysplasia of the hip (CDH) The Trinity Acetabular System is indicated for cementless, single use only.

Device Story

Modular acetabular cup system for total hip arthroplasty; consists of titanium alloy shell with UHMWPE, HXLPE, or vitamin E HXLPE liners; includes modular ceramic or CoCr heads. Subject device variants are non-occluded titanium plasma sprayed (TPS) shells with non-threaded holes for titanium screw fixation. Used in orthopedic surgery; implanted by surgeons to replace damaged hip joint articulation. Provides stable fixation via press-fit and optional screw fixation; restores joint mobility and reduces pain in patients with sufficient bone stock.

Clinical Evidence

No clinical data. Substantial equivalence determined via bench testing, including screw range of motion and coating characterization.

Technological Characteristics

Titanium alloy acetabular shell with titanium plasma spray coating. Non-threaded holes for titanium screw fixation. Modular design compatible with UHMWPE, HXLPE, and vitamin E HXLPE liners, and BIOLOX delta ceramic or CoCr heads. Cementless fixation.

Indications for Use

Indicated for skeletally mature patients undergoing total hip arthroplasty for non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or developmental/congenital hip dysplasia. Indicated for cementless, single-use only.

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.

6. Legally Marketed Devices to which Substantial Equivalence is claimed:

a. Corin Trinity Acetabular System (K093472)

b. Corin Trinity Acetabular System with HXLPE (K110087)

c. Corin Trinity Acetabular System with Trinity-i Acetabular Shells (K122305)

### 7. Device Description:

The Trinity Acetabular System is a modular acetabular cup system consisting of a press fit, titanium alloy shell with ultra .high molecular weight polyethylene (UHMWPE), highly cross-linked polyethylene (HXLPE) and vitamin E highly crosslinked polyethylene (ECiMa) acetabular liners in neutral offset, +4mm offset, +4mm oblique and neutral 4mm EPW. The Trinity system also includes BIOLOX delta™ ceramic and CoCr modular heads which are intended for use with Corin titanium femoral stems. The acetabular shell comes in two variants, a standard Trinity (K093472 and K110087) and a Trinity-i (K122305) shell, both coated with a rough titanium plasma spray with an additional top layer of electrochemically deposited

{1}------------------------------------------------

calcium phosphate (Bonit™). The Trinity and Trinity-i acetabular shells are provided with screw holes and come assembled with ttanium occluders in place. Dedicated titanium screws are also provided for additional fixation if required.

The purpose of this submission is to add two more acetabular shell variants to the Trinity Acetabular System, the standard Trinity Non-occluded Titanium Plasma Sprayed (TPS) acetabular shell and the Trinity-i Non-occluded Titanium Plasma Sprayed (TPS) acetabular shell. Both of these variants, subject of this submission, are coated with a rough titanium plasma spray, contain non-threaded holes for the use of titanium screw fixation and do not come pre-assembled with the hole occluders in place.

#### 8. Intended Use / Indications:

The Trinity Acetabular System is intended for use in total hip arthroplasty in skeletally mature patients, to provide increased mobility and reduce pain by replacing the damaged hip joint articulation where there is evidence of sufficient sound bone to seat and support the components.

The indications for the Trinity Acetabular System as a total hip arthroplasty include:

- Non-inflammatory degenerative joint disease including osteoarthritis and ಂ avascular necrosis
- Rheumatoid arthritis O
- Correction of functional deformity o
- Developmental dysplasia of the hip (DDH) or congenital dysplasia of the hip 0 (CDH)

The Trinity Acetabular System is indicated for cementless, single use only.

- 9. Summary of Technologies/Substantial Equivalence:
The standard Trinity Non-occluded TPS shell is identical to the standard Trinity Acetabular Shell cleared in K093472 and K110087 in terms of intended use, indications for use, substrate materials, and size range. Likewise, the Trinity-i Nonoccluded TPS shell is identical to the Trinity-i Acctabular Shell cleared in K122305 in terms of intended use, indications for use, substrate materials, and size range. The standard Trinity Non-occluded TPS and the Trinity-i Non-occluded TPS shells are similar in design to the Corin predicates with non-threaded holes for the use of titanium screw fixation and a rough titanium plasma spray coating only. The titanium plasma spray coating of the non-occluded TPS variants, subject of this submission, is similar to the titanium plasma spray coating of the United U2

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

Acetabular Component (K050262) and identical to the titanium plasma spray coating applied to predicates K093472, K110087, and K122305. Based on these similarities, the additional variants subject of this submission, are determined to be substantially equivalent to the predicate devices.

### 10. Non-Clinical Testing:

Non-clinical testing conducted to demonstrate substantial equivalence includes: screw range of motion and bench testing of the Trinity titanium shells and characterization and testing for the coating which were included in previous submissions for the Corin standard Trinity Acetabular Shells (K093472 and K110087) and the Trinity-i Acetabular Shells (K122305).

The results of this testing show that the Trinity and Trinity-i non-occluded TPS variants are expected to be safe and effective for the proposed indications and are substantially equivalent to the predicate devices.

#### 11. Clinical Testing:

Clinical testing was not necessary to determine substantial equivalence with the predicate devices.
