• Regulation: 21 CFR 888.3358
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Exactech Novation InteGrip 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 Exactech Novation InteGrip Acetabular Augment is affixed to the mating acetabular shell using PMMA bone cement. Therefore, acetabular shells with HA coating must not be used with InteGrip Acetabular Augments. The assembled construct is intended for press-fit fixation.

Device Story

Titanium alloy acetabular augments designed to address segmental acetabular deficiencies during primary or revision hip replacement. Augments are affixed to compatible acetabular shells using PMMA bone cement; the final construct is intended for press-fit fixation. Used by orthopedic surgeons in clinical settings. Modification expands size range to accommodate Novation Crown Cup acetabular shells (60-68mm). Provides structural support as an alternative to allograft.

Clinical Evidence

Bench testing only. Engineering evaluations were conducted to verify that the geometric features of the modified devices correspond to compatible acetabular shells and are dimensionally and functionally similar to the predicate device.

Technological Characteristics

Material: Titanium alloy. Design: Acetabular augments with screw holes and specific height configurations. Fixation: PMMA bone cement to shell; press-fit to bone. Sterilization: Gamma radiation (SAL 10^-6). Compatibility: Compatible with Novation Crown Cup acetabular shells (60-68mm); incompatible with HA-coated shells.

Indications for Use

Indicated for skeletally mature patients undergoing primary or revision hip replacement surgery requiring prosthetic alternatives 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.

# Exactech® Novation® InteGrip™ Acetabular Augments Special 510(k) - 510(k) Summary of Safety and Effectiveness

### Device Description:

The proposed Exactech Novation InteGrip Acetabular Augments are a modification of the Exactech InteGrip Acetabular Augments cleared through premarket notification #K101761.

The predicate and proposed devices have the same intended use and the same basic fundamental scientific technology.

The modified devices share the following similarities with predicate devices:

- . Indications for Use
- Design Features (e.g. screw holes, height configurations) �
- Material (titanium alloy) .
- . Shelf Life (5 years)
- Packaging and sterilization materials and processes (gamma radiation sterilization to a sterility assurance level of 10°)

The proposed devices include the following design change:

- Expand the current scope of augments to include sizes that are compatible with . the Novation Crown Cup acetabular shell sizes 60-68mm (both plasma spray and InteGrip).
### Substantial Equivalence Conclusion:

The following engineering analyses were conducted to demonstrate substantial equivalence of the proposed device to the predicate Exactech Novation InteGrip Acetabular Augments:

- An engineering evaluation to determine that the geometric features of the . proposed devices correspond to the compatible acetabular shells and are dimensionally and functionally similar to the predicate devices.
In addition to the design similarities, the results of engineering analyses demonstrate the proposed device is substantially equivalent to the predicate device.
