REFLECTION Constrained Liner Adaptor - Constrained polyethylene acetabular liner

Intended purpose

Hip components are indicated for individuals undergoing primary and revision surgery where other treatments or devices have failed in rehabilitating hips damaged as a result of degenerative joint disease or any of its composite diagnoses of osteoarthritis, avascular necrosis, and traumatic arthritis. Hip components are also indicated for inflammatory degenerative joint disease including rheumatoid arthritis, congenital dysplasia, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement that are unmanageable using other techniques, and fracture-dislocation of the hip deformity.

Functional description

A three-piece construct that is package-assembled on a plastic Y-shaped holder, designed to help align the rings during impaction. It attaches to any Reflection or Reflection Interfit shell and provides the pull-out strength necessary for constrained liner applications. The device is inserted into the shell and aligned by hand or with a hex screwdriver. It is impacted into the shell, which loosens the center Y-shaped holder for easy removal.
