Summary

This study investigates whether a specialized bone scan (bone scintigraphy) can more accurately diagnose cervical pseudarthrosis — a condition where neck bones fail to fuse after surgery. About 100 adults who had neck fusion surgery and still have symptoms will receive a bone scan in addition to their usual CT scan. The goal is to see if the bone scan improves detection of non-healing, potentially guiding better treatment decisions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Bone scintigraphy (a type of imaging test using a radioactive tracer to detect bone activity)
What this could lead to
If successful, this could provide a more accurate, non-invasive way to diagnose failed neck fusion, helping patients avoid unnecessary surgery.
What could go wrong
This is a small, early-stage study with no established interpretation criteria, and the test may not prove more reliable than current methods.
