Intended purpose

A component of the Delta Double Mobility System which is indicated for use in total hip arthroplasty for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: o Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis and hip dysplasia; o Rheumatoid arthritis; o Post-traumatic arthritis; o Correction of functional deformity; o Fractures, dislocation of the hip and unsuccessful cup arthroplasty; o Revisions in cases of good remaining bone stock.

Functional description

The Mobile Liner UHMWPE functions as part of a double mobility system. It is coupled with an outer liner before being fitted onto the head of a femoral stem. The inner liner provides the articulating surface within the outer liner and the coupled liner provides the articulating surface with the acetabular shell after insertion into the acetabular shell/Cup as part of a total hip arthroplasty.
