The OMNI Interface™ Acetabular System is designed to be used in hip arthroplasty. The specific indications for use include - - . Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; - Rheumatoid arthritis; - Correction of functional deformity; - Congenital dislocation; - Revision procedures where other treatments or devices have failed; - Femoral neck and trochanteric fractures of the proximal femur. The OMNI Interface Acetabular System is intended for cementless and single use implantation only.

The OMNI Interface Acetabular System consists of acetabular cups/shells that are made of titanium alloy, standard and crosslinked ultra high molecular weight polyethylene shell inserts and femoral heads that are used with compatible femoral hip stems for primary and revision total hip replacement. The shells are available in “no hole” and “3-hole” configuration and a size range from 46-76 mm and X size (48x-58xmm).

The Apex Interface™ Acetabular System is intended for use in combination with the Apex Modular Hip Stem in total hip replacement procedures. This acetabular cup is intended to articulate with a metal (cobalt chromium) or ceramic (alumina) femoral head. This prosthesis is intended for uncemented fixation and single use implantation, and may be used for the following conditions, as appropriate: Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Congenital dislocation; Revision procedures where other treatments or devices have failed; Femoral neck and trochanteric fractures of the proximal femur.

The Interface Acetabular System, Acetabular Shell is composed of titanium alloy (ASTM F136), coated with sintered unalloyed titanium beads. The shells are designed for cementless use. The two versions of the shells include a "no hole" and a "3 hole" version (plus an apical hole in both versions). The cup system includes titanium alloy cancellous bone screws (in separate sterile packaging) for optional supplemental fixation of the "3 hole" shell. The Shell uses plastic inserts manufactured from ultra high molecular weight polyethylene (UHMWPE, ASTM F648-00), machined from compression molded sheet, and sterilized using ethylene oxide.

The Apex Knee ™ Modular Tibia System is intended for use as a primary or revision total knee replacement. This prosthesis may be used for the following conditions, as appropriate: • Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis • Rheumatoid arthritis • Correction of functional deformity • Revision procedures where other treatments or devices have failed The porous coated femoral component may be used cemented or uncemented (biological fixation). The porous coated tibial baseplate component may be used uncemented (biological fixation). All other femoral, tibial baseplate and patellar components are indicated for cemented use only. The Apex Knee™ Modular Tibia System Tibial Augments are intended to be bolted to the Tibia baseplate and cemented to the prepared tibia.

The Modular Tibial Baseplate is offered in sizes 1 thru 6 and is a symmetrical design. It is 5mm thick, and accepts Tibial Stems and Augment Blocks on its inferior surface. Modular Tibia Stems are available from 9-17mm diameter in lengths of 75,100 or 150mm. The stem mates to the Modular Tibial Baseplate via a Morse taper connection, secured by a Locking Bolt. Modular Tibia Augments are available in, size 1 thru 6. Each Augment is 4mm thick, and may be placed on either the medial or lateral side of the baseplate. They may be stacked up to three high in equal or descending sizes to create either a uniform or stepped lateral profile. Bone cement should not be used between stacked augments. Once stacked the augments must be secured to the tibial tray using a locking bolt of appropriate length to match the height of the augment stack. The Tibial tray (tibial baseplate) - augment assembly is then cemented to the prepared tibia.

The Apex Hip System is intended for primary or revision total hip replacement. The femoral hip stems and acetabular cup are intended for uncemented fixation and single use implantation. These prostheses may be used for the following conditions, as appropriate: Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Congenital dislocation; Revision procedures where other treatments or devices have failed; Femoral neck and trochanteric fractures of the proximal femur.

Apex Modular Head sizes 28, 32, 36, and 40 mm with a + 10.5mm offset

The Apex Hip System Bipolar Head is intended for use in combination with an Apex Hip System femoral stem for uncemented primary or revision hemiarthroplasty of the hip. This prosthesis may be used for the following conditions, as appropriate: - . Femoral neck and trochanteric fractures of the proximal femur; - Osteonecrosis of the femoral head; - Revision procedures where other devices or treatments for these indications have failed.

The Apex Hip System Bipolar Head consists of a factory assembled Ultra High Molecular Weight Polyethylene (UHMWPE) liner in a cobalt chrome outer shell and UHMWPE retention ring with a Ti-6Al-4v spring. These bipolar heads include outer diameters ranging from 38 to 60 mm, in 1 mm increments, to properly fit the patient anatomy. The smaller bipolar heads (38 to 42 mm) have an inner diameter that mates with a 22 mm diameter femoral head; the larger bipolar heads (43 mm to 60 mm) have an inner diameter that mates with a 28 mm diameter femoral head. The Apex Hip System Bipolar Head may be used in conjunction with an Apex Hip System femoral stem (K060072) for hemiarthroplasty.

The Apex Knee System is intended for use as a primary or revision total knee replacement. This knee replacement system is intended for cemented fixation, with the option of using a porous coated femoral component for uncemented or cemented fixation. This prosthesis may be used for the following conditions, as appropriate: - Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; . - . Rheumatoid arthritis; - Correction of functional deformity; . - Congenital dislocation; ● - Revision procedures where other treatments or devices have failed. .

The Apex Knee System Porous Coated Femoral Components are part of the Apex Knee System for primary or revision total knee replacement. These cobalt chrome femoral components have a sintered porous coating (ASTM F1377). Fixation of the femoral component is achieved using either PMMA bone cement or by biological fixation via tissue ingrowth into the porous coating. The Apex Knee System consists of a range of sizes of femoral components with a deep patellar groove, dome shaped UHMWPE patella resurfacing components, UHMWPE tibial inserts, cobalt chrome tibial trays, and a titanium alloy bolt for locking the tibial insert to the tibial tray. This modular configuration allows the surgeon user to choose a combination of femoral and tibial tray component sizes to appropriately fit the anatomy of the patient, and to use a tibial insert with a sizefor-size match to the femoral component. There are two different articular geometries for the tibial insert, a cruciate retaining ("CR") design, which allows retention of the posterior cruciate ligament, and an ultra-congruent posterior cruciate substituting ("Ultra") design. For each tibial insert, a range of UHMWPE thicknesses are available to aid in obtaining the proper soft tissue balance across the knee joint.
