Dexmedetomidine versus hyaluronidase along with lumbar transforaminal epidural steroid injection in failed back surgery: a randomized double-blind clinical trial.

Background: Failed back surgery syndrome is a common problem faced by chronic pain management specialists. Steroid-only epidural injections have modest efficacy because of excessive scarring. Epidural hyaluronidase (HA), functions as a depolymerizing agent, successfully breaking down adhesions and collagen bundles, whereas dexmedetomidine (DEX) helps to reduce inflammation.

Efficacy of Atlantoaxial Joint Glucocorticoid Injection in Patients with Rheumatoid Arthritis: A Randomized Trial.

Unfortunately, it is the most common cervical spine joint that is affected in patients with rheumatoid arthritis. Inflammation of the AAJ results in neck disability, nerve root compression, and finally spinal cord compression.
