Summary

This study looked back at the medical records of 90 adults who received a stellate ganglion block (a nerve injection) for neck and arm pain caused by a pinched nerve. Researchers wanted to see if MRI findings, like fatty changes in neck muscles or bone spurs, could predict who would get good pain relief. The goal was to help doctors choose the right patients for this procedure and avoid unnecessary treatments.
