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 press-fit titanium alloy shell with UHMWPE, HXLPE, or vitamin E HXLPE liners. Subject device variants are 'No Hole' acetabular shells, lacking screw holes present in previous versions. Used in orthopedic surgery to replace damaged hip joint articulation; provides increased mobility and pain reduction. Components seated in sound bone; cementless fixation. Surgeon-operated in clinical/OR setting. Benefits patient through restoration of hip function and joint stability.

Clinical Evidence

No clinical data. Substantial equivalence determined via non-clinical design, material, and dimensional comparisons to predicate devices.

Technological Characteristics

Titanium alloy shell; rough titanium plasma spray coating; electrochemically deposited calcium phosphate (BONIT) top layer. Modular design for use with UHMWPE/HXLPE/ECiMa liners and ceramic/CoCr modular 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 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.

## 9. 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 cross-linked polyethylene (ECiMa) acetabular liners in neutral offset, +4mm offset, +4mm oblique,

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

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 calcium phosphate (BONIT™). The Trinity and Trinity-i acetabular shells are provided with screw holes and come assembled with titanium 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 No Hole acetabular shell and the Trinityi No Hole acetabular shell. Both of these variants, subject of this submission, are similar to the standard Trinity Acetabular shells previously cleared (K093472, K110087 and K122305) with the only difference being the shells subject of this submission do not have screw holes in them.

#### 10. 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 .
- 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.

## 11. Summary of Technologies/Substantial Equivalence:

The Trinity No Hole acetabular shells are 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 and are similar in design and performance. Likewise, the Trinity-i No Hole acetabular shells are identical to the Trinity-i Acetabular Shell cleared in K122305

### K130128 (pg 3/3)

in terms of intended use, indications for use, substrate materials, and size range and are similar in design and performance. The intended use, indications for use, substrate material, size range and design of the Trinity No Hole shells are similar to the DePuy Pinnacle 100 acetabular shell (K001534). Based on these similarities, the additional variants subject of this submission, are determined to be substantially equivalent to the predicate devices.

## 12. Non-Clinical Testing:

Non-clinical testing conducted to demonstrate substantial equivalence includes a comparison of the designs, materials, intended use, indications and dimensions of the additional Trinity Acetabular shells to the predicate devices. The results of this testing show that the Trinity and Trinity-i No Hole variants are expected to be safe and effective for the proposed indications and are substantially equivalent to the predicate devices.

#### 13. Clinical Testing:

Clinical testing was not necessary to determine substantial equivalence between the Trinity Acetabular System and the predicate devices.
