NCT ID NCT06696313
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the Insignia hip stem moves inside the body after a hip replacement. About 25 people with hip arthritis will get special X-rays and CT scans over two years to check for any shifting. The goal is to see if the stem stays stable and to compare two different scanning methods.
