Metallic acetabular liner

Dual mobility hip acetabular liners are components of total hip arthroplasty systems that provide increased stability by replacing the hip joint articulation through a two-piece design where an inner articulating surface is inserted into an acetabular shell . These devices are used in primary and revision hip replacement procedures for conditions including non-inflammatory degenerative joint disease, inflammatory joint disease, correction of functional deformity, traumatic injury, femoral neck fractures, and cases with elevated dislocation risks .
