Indications for Use
The Empire Acetabular Augments are indicated for use in skeletally mature individuals undergoing primary or revision surgery for hip replacement and whose orthopedic surgeon desires a prosthetic alternative to structural allograft in cases of segmental acetabular deficiencies. The Empire Acetabular Augment is affixed to the mating acetabular shell using PMMA bone cement. Therefore, acetabular shells with HA coating must not be used with Empire Acetabular Augments. The assembled construct is intended for press-fit fixation. The construct may also be used with bone cement at the discretion of the surgeon.
Device Story
Empire Acetabular Augments are titanium alloy implants manufactured via additive manufacturing to create a porous structure for mechanical and biological fixation. Used in primary or revision hip replacement surgery to address segmental acetabular deficiencies; serves as an alternative to structural allograft. Augments are affixed to Novation Crown Cup acetabular shells using PMMA bone cement; construct is intended for press-fit fixation, though bone cement may be used at surgeon discretion. Augments feature holes for 4.5mm bone screws for adjunct fixation. Available in three heights (8mm, 11mm, 13mm) for shell diameters 48-58mm. Operated by orthopedic surgeons in clinical/OR settings. Provides structural support to the acetabulum, potentially improving implant stability and patient outcomes in complex revision cases.
Clinical Evidence
No clinical trials performed. Evidence includes cadaver lab validation of design features, mechanical testing per FDA guidance for modified metallic surfaces, animal study comparing biological fixation of porous Ti-6Al-4V to historical data, and clinical literature review of predicate devices.
Technological Characteristics
Material: Ti-6Al-4V titanium alloy. Manufacturing: Additive manufacturing (porous structure). Dimensions: 8mm, 11mm, 13mm heights; 48-58mm diameters. Fixation: PMMA bone cement to shell; press-fit or cement to bone. Sterilization: Provided sterile for single use.
Indications for Use
Indicated for skeletally mature patients undergoing primary or revision hip replacement surgery requiring a prosthetic alternative to structural allograft for segmental acetabular deficiencies. Contraindicated for use with HA-coated acetabular shells.
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.
