Can a catheter in bone tell surgeons if a graft is healthy?
NCT ID NCT01879384
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether a small microdialysis catheter placed directly into a bone graft could monitor blood flow and healing after head and neck reconstruction. Thirty-four people having surgery with bone from their hip or leg took part. The goal was to see if the catheter could reliably measure key chemicals in the bone tissue.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
CMA 70 microdialysis catheter (device placed in bone tissue)
What this could lead to
If successful, this method could give surgeons a reliable way to check if bone grafts are healing properly after head and neck reconstruction.
What could go wrong
This is a small feasibility study with only 34 participants, so results may not apply widely. The catheter placement is experimental and may not always work.
