Drez lesioning explained by Dr. Rohit Mishra: Hope for patients with chronic spine pain


Chronic spine pain can have a significant impact on your life, affecting daily activities, mobility, and overall well-being. For patients who have tried everything without success, Drez lesioning may offer a glimmer of hope. In this blog, learn how it can be a life-changing treatment for those struggling with chronic pain.

What is a Drez Lesioning Procedure?

Drez lesioning is a specialized surgical procedure designed to treat chronic pain, especially in the spine. It involves making small lesions on the dorsal roots of the spinal cord to block pain signals from reaching the brain. The dorsal roots are responsible for transmitting pain signals, and by interrupting this transmission, patients often experience significant pain relief. This is suitable for conditions like failed back surgery syndrome, post-herpetic neuralgia, and complex regional pain syndrome.

The procedure is done under local anesthesia, meaning the patient remains awake during the process. This allows the surgeon to precisely target the affected area and minimize risk. For many patients, Drez lesioning offers long-term relief from chronic pain.

What is the Success Rate of Drez Procedure?

The success rate of the Drez lesioning procedure is quite high. The success of the procedure largely depends on the condition being treated, the patient’s overall health, and the extent of the pain. While results vary, many patients report long-lasting improvements that allow them to return to their normal daily activities.

In some cases, the pain relief is immediate, while for others, it may take some time to feel the full benefits. Dr. Mishra, the best spine surgeon in Kolkata, works closely with his patients to monitor progress and ensure the best possible outcome.

What Does Drez Stand For?

The term Drez is an abbreviation for Dorsal Root Entry Zone, which refers to the area where

the sensory nerve roots enter the spinal cord. The Drez lesioning procedure targets this area to interrupt pain signals before they can travel to the brain. By carefully making lesions in this region, the doctor can help block the signals responsible for chronic pain, providing patients with much-needed relief.

What Happens to the Body if the Dorsal Root is Damaged?

The dorsal root of the spinal nerve is responsible for carrying sensory information, including pain, to the brain. If this root is damaged, it can result in a loss of sensation, extreme pain, or other neurological issues in the affected area of the body. For patients with chronic pain conditions, damage to the dorsal root can make it difficult to find relief from their symptoms.

Drez lesioning works by selectively interrupting these pain signals, providing a much-needed solution for patients who have not found success with other treatments. This technique is highly effective in treating pain conditions that stem from nerve damage, offering a new hope for many.

Move Forward Towards a Pain-free Life

If you’re struggling with chronic spine pain and haven’t found relief through other treatments, Drez lesioning may be the solution you’ve been waiting for.
