Active Articulation Dual Mobility Bearing E1 Antioxidant Infused UHMWPE - Non-constrained polyethylene acetabular liner

Intended purpose

The Active Articulation E1 (Antioxidant Infused Technology) Hip Bearing is designed to fit over 22.2mm and 28mm modular heads. The modular head articulates with the Active Articulation E1 Hip Bearing, which in turn articulates with a G7 Dual Mobility liner inside a G7 Acetabular Shell, or a Biomet acetabular shell. The components are intended for use with either primary or revision hip arthroplasties where all devices associated with the wear couple are removed and replaced. Indications include: Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques; Revision of previously failed total hip arthroplasty; Dislocation risks. Intended for uncemented applications.

Functional description

E1, highly cross-linked UHMWPE and α-tocopherol dual mobility bearing designed to fit over 22.2 and 28mm modular head with a Type 1 or Type 12/14 taper and may only be used with G7 cobalt chrome liners. The femoral head articulates on the inner, concave surface of the Active Articulation Bearing. Once the femoral stem contacts the Active Articulation Bearing, a secondary motion occurs between the Active Articulation Bearing and the CoCr Liners. Intended for uncemented applications.
