ADVANCED MATERIALS 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 an impressive initial scratch fit.

ADVANCED FIXATION LOCKING SCREW OPTION GRIPTION TF implants have the ability to use locking screws to fixate the Augment to host bone. Locking screws help prevent the screw from becoming loose and backing out of the Augment. This minimises the risk of compromising the fixation as a result of screw migration. In addition, GRIPTION TF enables surgeons to implant diverging locking screws for even stronger fixation to the host bone.

CEMENT, CEMENTLESS OR HYBRID FIXATION OPTIONS Prior to the availability of the GRIPTION TF Augments, the recognised method of securing the Augment to the cup was with bone cement. The introduction of the GRIPTION TF Augments allow surgeons to select between cementless, cemented and hybrid options of Augment to cup fixation. TRUEBOND Cementless Technology The Truebond Cementless Technology and Hybrid ﬁ xation is achieved by using a short 6.5mm screw through the cup into the augment.

KEY BONE STOCK AND LANDMARK CONSIDERATIONS Radiographic landmarks are helpful in assessing the acetabular bone stock. It can also be useful to order a CT scan of the area with a metal suppression technique. A CT scan will often indicate significantly more lysis than what is apparent on plain radiographs, and can also aid in determining pelvic discontinuities or loss of structural bone. Bone Stock Considerations Completely supportive acetabulum – PINNACLE Hip Solutions Shell Partially supportive acetabulum – PINNACLE Hip Solutions Shell with GRIPTION TF Augments Non-supportive – PINNACLE Hip...
