Intended Use

This device is indicated for use in total hip replacement or bipolar hip replacement undergoing primary and revision surgery for the following conditions: non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusion acetabuli, and painful hip dysplasia; inflammatory degenerative joint disease such as rheumatoid arthritis; correction of functional deformity; treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques; revision procedures where other treatments or devices have failed. This device is designed for cementless use.

Device Story

Modular, wedge-shaped femoral hip stem; forged from Ti-6Al-4V alloy; features 12/14 neck taper; proximal portion plasma-coated with CP Ti powder for cementless fixation. Size extension to existing UTF Stem-Reduced line. Used by orthopedic surgeons in hospital settings for primary or revision hip arthroplasty. Provides structural support for prosthetic hip joint; restores joint function; alleviates pain associated with degenerative or traumatic hip conditions.

Clinical Evidence

Bench testing only. Mechanical property analysis performed to compare new sizes against existing range; no clinical data provided.

Technological Characteristics

Modular, wedge-shaped femoral stem; Ti-6Al-4V alloy (ASTM F136); proximal plasma coating with CP Ti powder (ASTM F1580); 12/14 neck taper; cementless design.

Indications for Use

Indicated for patients undergoing primary or revision total or bipolar hip replacement for non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis, ankylosis, protrusion acetabuli, painful hip dysplasia), inflammatory degenerative joint disease (rheumatoid arthritis), functional deformity, or non-union/fractures of the proximal femur unmanageable by other techniques.

Regulatory Classification

Identification

A hip joint metal/polymer/metal semi-constrained porous-coated uncemented 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.

#### Device Description:

This subject device is a size extension to the cleared "UNITED" UTF Stem-Reduced (K123550). The indications, materials, design of this subject device are identical to the cleared "UNITED" UTF Stem-Reduced except for its large size. As the same as the cleared UTF Stem-reduced (K123550), the subjected device forged from Ti-6A1-4V alloy (ASTM F136), is a modular, wedge-shaped stem with 12/14 neck taper. The proximal part of each femoral stem is plasma coated with CP Ti powder (ASTM F1580).

#### Indications:

This device is indicated for use in total hip replacement or bipolar hip replacement undergoing primary and revision surgery for the following conditions: non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusion acetabuli, and painful hip dysplasia; inflammatory degenerative joint disease such as rheumatoid arthritis; correction of functional deformity; treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable using other techniques; revision procedures where other treatments or devices have failed.

This device is designed for cementless use.

#### Basis for Substantial Equivalence:

The subject device is a size extension to the cleared "UNITED" UTF Stem-Reduced (K123550). The indications, materials, design, manufacturing process and sterilization method of the subject device are identical to the cleared "UNITED" UTF Stem-Reduced (K123550).

#### Performance Data:

The mechanical properties of this device have been evaluated, and the analysis results shown that this subjected device (#12~#14) is not the worst case within all sizes of UTF Stem-reduced (#1~#14). This device modification would not affect the safety and effectiveness.
