This video shows the importance of needle placement during a transforaminal epidural steroid injection under fluoroscopic guidance.
The needle is initially placed in what looked like, and felt like, an excellent position. The contrast is injected, but it stays exclusively outside the foramen in what appears to be a neurogram only. The needle was then advanced merely another millimeter or two, which then yielded an excellent epidural spread of the contrast. This could have been the difference between an ineffective and a successful epidural steroid injection for lumbar radiculopathy pain.
