Intended Use

Exactech AcuMatch® A-Series and MCS® Acetabular Shells and Liners are indicated for use in skeletally mature individuals undergoing primary surgery for hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degenerative problems of the hip, and for treatment of proximal femoral fractures where prosthetic replacement is determined by the surgeon as the preferred treatment. Components of Exactech Hip Systems are also potentially indicated for ankylosing spondylitis, congenital hip dysplasia, revision of failed previous reconstructions where sufficient bone stock is present, and to restore mobility resulting from previous fusion.

Device Story

Acetabular shells and liners for total hip arthroplasty; used with Exactech femoral stems and heads. Metal shells composed of titanium alloy (Ti-6Al-4V) with porous coating (titanium beads, blast finish, or hydroxylapatite); liners machined from compression-molded UHMWPE. Device provides prosthetic hip joint surface; implanted by orthopedic surgeons in clinical/OR settings. Intended to restore mobility and treat degenerative hip conditions or fractures. Line extension of previously cleared systems; no new clinical data required.

Clinical Evidence

No clinical data. Substantial equivalence supported by design control assessments and performance testing reviewed in predicate device submissions.

Technological Characteristics

Metal shells: Ti-6Al-4V titanium alloy (ASTM F136) with porous coating (titanium beads, blast finish, or hydroxylapatite). Liners: UHMWPE (ASTM F648). Semi-constrained, porous-coated, uncemented prosthesis.

Indications for Use

Indicated for skeletally mature patients undergoing primary hip replacement or revision due to osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degeneration, proximal femoral fractures, ankylosing spondylitis, congenital hip dysplasia, or previous fusion.

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.

Premarket Notification - Special 510(k) Premarket Nothication - Special 510(K)
Exactech AcuMatch A-Series " and MCS " Acetabular Shells and Liners

#### Description:

Exactech AcuMatch A-Series® & MCS® Acetabular Shells and Liners are designed for use with appropriately sized Exactech femoral stems and heads.

The metal shells are made from titanium alloy (Ti-6Al-4V) conforming to ASTM F136. They are porous coated with titanium beads, a blast finish, or with hydroxylapatite.

The liners are machined from compression molded ultra-highmolecular-weight polyethylene (UHMWPE). Polyethylene raw material must meet all aspects of ASTM F648.

#### Intended Use:

Exactech AcuMatch® A-Series and MCS® Acetabular Shells and Liners are indicated for use in skeletally mature individuals undergoing primary surgery for hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degenerative problems of the hip, and for treatment of proximal femoral fractures where prosthetic replacement is determined by the surgeon as the preferred treatment. Components of Exactech Hip Systems are also potentially indicated for ankylosing spondylitis, congenital hip dysplasia, revision of failed previous reconstructions where sufficient bone stock is present, and to restore mobility resulting from previous fusion.

## Substantial Equivalence:

The devices are line extensions, identical to previously cleared Exactech AcuMatch® (K993082 & K000242) and MCS® (K921114 & K990197) Shells and Liners.

Exactech AcuMatch A-Series & and MCS ® Acetabular Shells and Liners

### Performance Testing:

Testing for the Exactech AcuMatch® A-Series and MCS® Acetabular Shells and Liners was performed for, and reviewed, in predicate device submissions. Design Control assessments did not indicate a need for additional testing for the line extensions which are the subject of this Special 510(k).

### Conclusions:

The new sizes of Exactech AcuMatch® A-Series and MCS® Acetabular Shells and Liners are substantially equivalent to existing previously cleared devices in design, materials of construction, manufacturing, and other characteristics. The changes in the devices have been done under the control of Design Assurance, and no new unmitigated risks were identified for these line extensions. The predicate products have been shown to be an effective design, with an acceptable performance history.

The contents of this submission demonstrate that the device additions are eligible for review and clearance under the special 510(k) premarket notification process.
