Acetabular Components with Radiological Markers for a Hip Replacement Implant

摘要

An acetabular component of a hip replacement implant that is configured to be attached to an acetabulum and to receive a femoral component of the hip replacement implant. The component includes a concave body with a closed end configured to seat against the acetabulum and an open end configured to receive the femoral component. At least one radiological marker is positioned on the body and is visibly distinct from the body on X-ray imaging. The radiological markers may include an elongated shape with a length measured between a first end and a second end. The radiological markers may be shorter than the body such that they do not extend completely around the body and the first and second ends are spaced apart from one another.

1. An acetabular component of a hip replacement implant configured to be attached to an acetabulum and to receive a femoral component of the hip replacement implant, the acetabular component comprising:
a concave body with a closed end configured to seat against the acetabulum and an open end configured to receive the femoral component, the body further comprising inner and outer sides, and a circular rim that extends around the open end; at least one radiological marker on the body and being constructed from a material that is visibly distinct from the body on X-ray imaging, each of the radiological markers comprising an elongated shape with a length measured between a first end and a second end; each of the radiological markers being positioned at the rim of the open end of the body where the length of the radiological marker is less than a circumference of the body with the first and second ends of the radiological marker being spaced apart.
