Intended Use

The ULTIMA and ULTIMA LX Femoral Hip Stem is indicated for use in total or partial hip replacement procedures for patients suffering severe pain and disability due to structural damage in the hip joint from rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, collagen disorders, avascular necrosis, traumatic and non-union of femoral fractures. Use of the prosthesis is also indicated for patients with congenital hip dysplasia, protrusio acetabuli, slipped capital epiphysis, and disability due to previous fusion, where bone stock is inadequate for other reconstruction techniques. The ULTIMA and ULTIMA LX Cemented Femoral stem is indicated for use only with PMMA bone cement.

Device Story

Femoral component for total or partial hip arthroplasty; implanted with PMMA bone cement. Used in conjunction with acetabular component and modular hip head. Features include collared or collarless (ULTIMA LX) designs, polished or grit blast finishes, and proximal slot for instrumentation. Available in 135-degree (centralized) or 130-degree (medialized) neck angles to facilitate anatomical head positioning. Used by orthopedic surgeons in clinical settings. Provides structural support for hip joint; restores mobility; reduces pain in patients with severe joint damage.

Clinical Evidence

No clinical data provided; substantial equivalence based on design, material, and functional comparison to predicate device.

Technological Characteristics

Cemented femoral hip prosthesis. Materials: metal/polymer. Design: collared/collarless, polished/grit blast finish, proximal slot. Neck angles: 130/135 degrees. Modular compatibility with P.F.C. Hip Heads. Implanted with PMMA bone cement.

Indications for Use

Indicated for patients requiring total or partial hip replacement due to severe pain/disability from rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, collagen disorders, avascular necrosis, femoral fractures, congenital hip dysplasia, protrusio acetabuli, slipped capital epiphysis, or previous fusion with inadequate bone stock. Must be used with PMMA bone cement.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).

Predicate Devices

• ULTIMA Total Hip System Cemented Femoral Stem (K924379)

### Statement of Substantial Equivalence__________________________________________________________________________________________________________________________________________

The modifications to the ULTIMA Cemented Femoral Stem which include surface finishes of polished and grit blast, collared and collarless (ULTIMA LX) and an increase in offset, and a larger proximal slot are substantially equivalent and identical in material and in function to the ULTIMA Total Hip System Cemented Femoral Stem cleared for marketing under premarket notification #K924379 (February 12, 1993).

The subject device is composed of similar materials to the predicate device mentioned above. Further, the intended use, design, and manufacture of the modified ULTIMA and ULTIMA LX Cemented Femoral Stem are substantially equivalent to those currently distributed. Additionally, the packaging and method of sterilization utilized for the ULTIMA and ULTIMA LX Cemented Femoral Stem are the same as those used for the previously mentioned predicate device.

ULTIMA and ULTIMA LX Cemented Femoral Stem

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

The ULTIMA and ULTIMA LX Cemented Femoral Hip Stem is indicated for use in total or partial hip replacement procedures for patients suffering severe pain and disability due to structural damage in the hip joint from rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, collagen disorders, avascular necrosis, traumatic and non-union of femoral fractures. Use of the prosthesis is also indicated for patients with congenital hip dysplasia, protrusio acetabuli, slipped capital epiphysis, and disability due to previous fusion, where bone stock is inadequate for other reconstruction techniques.

The ULTIMA and ULTIMA LX Cemented Femoral Stem is indicated for use only with PMMA bone cement.

### Physical Description

The ULTIMA and ULTIMA LX Cemented stem is a femoral component for use in total or partial hip arthroplasty procedures. It is designed to be implanted with Polymethylmethacrylate bone cement (PMMA) and used in conjunction with a total hip acetabular component and modular hip head. The ULTIMA and ULTIMA LX Femoral Hip Stems can be used in either the right or left hip.

The stem body design is derived from that of the primary ULTIMA stems K#924379. These stems will be offered in both a collared and collarless (ULTIMA LX) design, with either a polished or grit blast finish and a larger proximal slot. The stems have also been designed with a proximal slot to allow the surgeon an additional instrumentation choice during the seating of the implant.

Both the ULTIMA and ULTIMA LX femoral components are available with either a neck angle of a 135 (centralized) or a neck angle of 130 (medialized) to allow for more accurate anatomical head positioning for the patient. The ULTIMA and ULTIMA LX femoral components can be utilized with the P.F.C. Modular Hip Heads (previously cleared K# 893872) of various neck heads diameters (22.225, 26, 28, and 32 mm) and three neck lengths of standard, +5 mm and +10 mm. The 28 mm head and the 32 mm head are also available with a neck length of -3 mm and -5 mm, respectively.
