DESIGN RATIONALE
Augment
The GRIPTION TF Augments are designed to act as a defect filling implant in the case of severe bone loss in the acetabulum.
Design and geometry is designed to provide increased surface area for bone contact.
Screw holes engineered to improved fixation capability. 5.5 mm locking or 5.0 mm non-locking screws can be utilized on the outer rim.
Screwhole cutaways designed to fit with PINNACLE Shell System.
Proprietary TRUEBOND Locking Slot to help mechanically secure Augment to acetabular shell using a PINNACLE® 6.5 mm Bone Screw. Additionally bone cement can be used along with the screw for hybrid fixation, or cement only can be used. See pages 10 - 11 for more information.
Tight radius inner diameter to achieve precise fit with shell.
Divergent screw options to support fixation

SYSTEM OVERVIEW
The GRIPTION TF Buttress is designed to support the shell in a similar manner as the Augments. It is important to note the Buttress implant spans the defect in the acetabulum and must be cemented to the shell.
Tapered curved surface for ease of implantation
Angled screw holes for use with 5.5 mm locking/5.0 mm non-locking screws
Screw holes for use with PINNACLE 6.5 mm Bone Screws.
Curved spherical radius to mate with Acetabular Shell
Buttress
Neutral, left and right configurations available for different implant positioning

SYSTEM OVERVIEW
The GRIPTION TF Shim Implants are designed to mate with the Buttress via cement to raise the end of the Buttress when pelvic geometries require support.
Oversized holes for clearance of locking/non-locking screws
Available in 5, 10 and 15 degree configurations

Fixation
The GRIPTION TF Material is a completely porous structure made from commercially pure titanium. It provides a modulus of elasticity similar to bone, and a coefficient of friction that allows for initial scratch fit.

Locking Screw Option
GRIPTION TF Implants have the ability to use locking screws to fixate Augments and Buttresses to the host bone. The Locking Screw Mechanism designed to help prevent the screw from becoming loose and backing out of the implant. In addition, GRIPTION TF Augments designed to allow allow surgeons to implant diverging locking screws for even stronger fixation to the host bone.
5.5 mm Locking Screws can be utilized in the inner diameter of the augment as well as on the outer rim as shown in the image.
When using with Buttresses, 5.5 mm Locking screws can be utilized in the proximal four screw holes of the Buttress.
Note: Locking Screws should not be placed in the Truebond Locking Slot of the Augment. The TRUEBOND Locking Slot is only compatible with a 6.5 mm PINNACLE Bone Screw.

Screw Placement
5.0 mm non-locking screw or 5.5 mm polyaxial locking screw
5.5mm GRIPTION TF Locking ScrewsNote: On the 10 mm thick augments the two outside holes on the outer periphery are for Threaded Headed pin placement only. Do not place screws through these two holes.
6.5 mm PINNACLE Cancellous Bone Screw
5.5 mm GRIPTION TF Locking or 5.0 mm Peripheral Non-Locking Screws
Oversized through-holes on the Shims allow for the 5.5 mm Gription TF Locking or the 5.0 mm Peripheral Non-Locking Screws to pass through.
6.5 mm PINNACLE Bone Screws ONLY
Note: The 6.5 mm PINNACLE Bone Screw is only used in the event of Mechanical Screw Fixation of the Augment to the Cup. This screw will go from the PINNACLE Cup into the Augment TRUEBOND Slot.
15GRIPTION® TF Acetabular Revision Solutions Design Rationale DePuy Synthes
The option is also available for 5.0 mm PINNACLE Non-Locking Screws to be placed on the flat outer rim of the augment and the proximal four screw holes of the Buttress.
Note: Do not place PINNACLE Non-Locking Screws in the inner diameter screw holes of the Augment. The only time a screw is used with the TRUEBOND Locking Slot of the Augment is for mechanical fixation of the PINNACLE Cup to the GRIPTION TF Augment.

INCREASED COMPATIBILITY
The instruments for the GRIPTION TF System were designed to provide ease of use and consistency for the surgeon and OR team. The finishing rasps, modular rasps, and accompanying PINNACLE Cup Instrumentation are designed to allow for an increased conformity between the prepared bone and the implant.
Every augment in the TF range has a matching finishing rasp designed to create a press-fit bone envelope.
