Intended Use

The Master stems are indicated for use in partial or total hip arthroplasty and are intended for press-fit (uncemented) use. When used in total hip arthroplasty, the Master Stems are intended for use with Co-Cr-Mo femoral heads and cemented cups or with Co-Cr-Mo femoral heads and Delta TT Acetabular System. When used in partial hip arthroplasty, the MasterSL stems are intended for use with Lock Bipolar Heads. Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: - non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia; - rheumatoid arthritis; - treatment of femoral head and neck fractures; - revisions in cases of good remaining femoral bone stock.

Device Story

MasterSL Femoral Stem is a monolithic, collarless, tapered wedge-shaped implant for press-fit uncemented hip arthroplasty. Device is surgically implanted by orthopedic surgeons in a clinical/hospital setting. Stem features a Ti6Al4V alloy body with a plasma-sprayed titanium alloy coating on the proximal half for osseointegration; distal anterior/posterior surfaces include vertical grooves for rotational stability. Neck features a 12/14 conical taper for coupling with femoral heads (Co-Cr-Mo) and is mirror-polished to minimize abrasion against the acetabular cup. Available in 13 sizes with standard/lateralized versions and varying CCD angles. Device restores hip function and reduces pain by replacing the femoral head/neck. Clinical benefit derived from mechanical stability and articulation within the hip joint.

Clinical Evidence

No clinical data provided. Substantial equivalence demonstrated via bench testing, including fatigue resistance testing per ISO 7206-4 and ISO 7206-6, and characterization of the titanium plasma spray coating.

Technological Characteristics

Monolithic, collarless, tapered wedge-shaped femoral stem. Material: Ti6Al4V alloy (ASTM F1472/ISO 5832-3). Surface: Proximal plasma-sprayed titanium alloy coating. Features: 12/14 conical taper, vertical distal grooves for rotational stability, mirror-polished neck. Available in 13 sizes, standard/lateralized versions, various CCD angles. Non-active, mechanical implant.

Indications for Use

Indicated for skeletally mature patients requiring partial or total hip arthroplasty for non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis, hip dysplasia), rheumatoid arthritis, femoral head/neck fractures, or revisions with good remaining femoral bone stock.

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.

#### Description:

The Master femoral stem is a monolithic, collarless, tapered wedge shaped stem intended for press-fit uncemented partial or total hip arthroplasty. When used in total hip arthroplasty the stem is coupled to a Limacorporate Femoral Heads (K112158) and used with either a Limacorporate Cemented Cups (K112158) or Limacorporate Delta TT Acetabular System cup (K112898). When used in partial hip arthroplasty the Master" femoral stem is coupled to a Limacorporate Femoral Heads (K112158) and used with a Lock Bipolar Head (Limacorporate K112158).

The Master" femoral stem is made of Ti6A14V alloy conforming to ASTM F1472 - ISO 5832-3; the proximnal 1/2 of the stem a plasma sprayed coating of titanium alloy (ASTM F1472 - ISO 5832-3). The stem has a tapered rectangular section and the distal anterior and posterior surfaces have a vertical groove for rotational stability. The stem provides a

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

neck with a 12/14 conical taper to couple to Limacorporate Femoral Heads and the necks are mirror-polished and lowered to reduce accidental abrasion and contact between the stem neck and the acetabular cup. The Master stems is available 13 sizes in both standard and lateralized versions with different CCD angles.

#### Intended Use:

The Master stems are indicated for use in partial or total hip arthroplasty and are intended for press-fit (uncemented) use. When used in total hip arthroplasty, the MasterSL Stems are intended for use with Co-Cr-Mo femoral heads and cemented cups or with Co-Cr-Mo femoral heads and Delta TT Acetabular System. When used in partial hip arthroplasty, the MasterSL stems are intended for use with Lock Bipolar Heads.

Hip arthroplasty is intended for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions:

- · non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia;
- · rheumatoid arthritis;
- · treatment of femoral head and neck fractures;
- · revisions in cases of good remaining femoral bone stock.

#### Predicate Devices:

- . H-MAX S stems (Limacorporate, K112091):
- . Encore Linear Hip (DJO, K972791 and K991325);
- Modulus Femoral Hip System (Limacorporate, K112158); .
- Taperloc 12/14 Taper Femoral Component (BIOMET, K043537). .

#### Comparable Features to Predicate Device(s):

The Master stems are substantially equivalent to the predicate devices in terms of intended use, indications for use, design and materials. As for all of the predicates, the Master stems is intended for use in total hip arthroplasty and like the Modulus Femoral Hip System predicate (K112158), it can also be used in partial hip arthroplasty. Like all of the predicates, the subject MasterSL stem is intended for press-fit cementless use.

The Master" stems are manufactured from the same materials as the predicate devices. The Master Stem has a tapered wedge design which is similar to all of the predicates exception that predicate Modulus stem is a 2-piece stem with the components coupled through a conical taper while the other predicates and the subject device are all one pice monolithic stems. Like all of the predicates, the subject device is available in standard and lateralized versions, with different CCD angles, offsets and sizes.

### Non-Clinical Testing:

The Master stems were tested in worst case configurations for fatigue resistance according to ISO 7206-4 and ISO 7206-6.

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

The ROM of the Master 5- hip stem was analyzed using the worst case construct.

The Titanium Plasma Spray coating was characterized to verify the conformity to FDA guideline and referenced standards.

### Clinical Testing:

Clinical testing was not necessary to demonstrate substantial equivalence of the Master St Femoral Stem to the predicate devices. -
