## Indications for use
The PLUS-FIT Acetabular Cup is intended for all types of arthrosis, such as advanced destruction of the hip joint due to degenerative, post-traumatic or rheumatoid arthritis, fracture or avascular necrosis of the femoral head, sequelae of previous operations, such as internal fixation, joint reconstruction, arthrodesis, hemiarthroplasty or total hip replacement. The same considerations apply to acetabular revisions. In normal cases, however, the surgeon will use an acetabular implant one size larger and in exceptional cases two sizes larger.
