GRIPTION® TF Acetabular Revision System
GRIPTION® TF Acetabular Revision System is an innovative technology for addressing bone defects in complex acetabular revision surgery. It represents one of the latest advances in materials, fixation, and instrumentation technologies. The system features augments, buttresses, and shims.
The GRIPTION TF System Material is a completely porous structure made from commercially pure titanium. It is designed to provide a modulus of elasticity similar to bone, and a coefficient of friction that allows for initial scratch fit.Advanced Fixation
The GRIPTION TF Augments allow surgeons to select between cement-less, cemented, and hybrid options of Augment to shell fixation.Advanced Instrumentation
The instruments for the GRIPTION TF System were designed to provide ease of use and consistency for the surgeon and OR team.Radiographic landmarks can be 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.Once the acetabulum has been exposed and evaluated,
preparation for the acetabular construct can begin. Start
by reaming the acetabulum with an undersized reamer
at a level that will restore the appropriate center of
rotation. Ream concentrically with progressively larger
reamers – maintaining appropriate opening abduction
