Rhizotomy is a surgical procedure that involves damaging certain nerves through cutting, chemical ablation, or radiofrequency ablation to treat chronic pain or spasticity. It is a last-resort treatment option for patients who have not found relief from pain through other methods such as medication and physical therapy. Rhizotomy can be performed on various parts of the body, with the spinal cord being the most common location. The procedure aims to sever nerve fiber roots that transmit pain signals to the brain, providing instant pain relief that typically lasts several years. While it does not kill muscle, rhizotomy can help reduce muscle spasms and improve muscle function by interrupting pain sensations.
| Characteristics | Values |
|---|---|
| Purpose | Rhizotomy is a procedure that involves damaging certain nerves through surgical cutting, chemical ablation, or radiofrequency ablation to treat chronic pain or spasticity. |
| Nerve Function | Nerves carry electrical signals between the brain and the rest of the body, helping to feel sensations like touch and pain, and move muscles. |
| Muscle Function | Rhizotomy can reduce muscle spasms by cutting off the signals from nerves that cause them. It can also improve communication between the spine and muscles. |
| Muscle Contraction | Rhizotomy can prevent extreme muscle scarring and joint and bone deformities by reducing continuous muscle contraction in patients with cerebral palsy. |
| Muscle Weakness | Rhizotomy can cause muscle weakness in some cases, such as masseter and masticatory muscle weakness after percutaneous rhizotomy. |
| Muscle Stiffness | Rhizotomy can decrease muscle stiffness and improve underlying muscle function, especially in patients with cerebral palsy. |
| Muscle Movement | Rhizotomy can improve mobility and range of motion by reducing pain and enhancing movement in afflicted joints. |

What You'll Learn
Rhizotomy is a treatment for chronic pain
There are several types of rhizotomies, each targeting different nerves to treat specific causes of pain. For example, facet rhizotomy is used to treat back and neck pain from arthritis, herniated discs, or spinal stenosis, while trigeminal neuralgia addresses facial pain due to irritation of the trigeminal nerve. Selective dorsal rhizotomy is a type of rhizotomy that can improve communication between the spine and muscles in people with cerebral palsy spasticity.
The procedure is typically performed as a minimally invasive surgery, with patients often returning home the same day and resuming work within a few days. It provides immediate pain relief that can last for several years, after which the nerve may recover and transmit pain signals again. During the procedure, a surgeon may use a surgical instrument, chemical agents, or an electrical current to destroy the nerve fibres causing pain.
While rhizotomy can be an effective treatment for chronic pain, it is important to note that it does not offer a 100% success rate. Some patients may experience a gradual return of pain after several years, requiring further treatment options such as decompression surgery or a second rhizotomy. It is always best to consult with a healthcare provider to determine if rhizotomy is the right treatment option for an individual's specific needs.

Rhizotomy can reduce muscle spasms
Rhizotomy is a surgical procedure that involves damaging certain nerves through cutting, chemical ablation, or radiofrequency ablation to treat chronic pain or spasticity. It is a last-resort treatment option for patients who have not found relief from pain through other methods, such as medication and physical therapy.
One of the goals of a rhizotomy is to reduce muscle spasms caused by spasticity, a condition that affects people with cerebral palsy. Spasticity causes certain muscles to contract all at once, making daily tasks painful and affecting mobility. Selective dorsal rhizotomy (SDR) is a type of surgery that specifically targets these sensory nerve fibers in the lower spinal cord, helping to reduce muscle spasms and improve communication between the spine and muscles.
During the procedure, surgeons may use open surgery or an endoscopic approach. In the latter, a tiny incision is made, and a small camera tool is inserted to locate and cut the nerves. The rhizotomy itself takes only a few minutes, but the patient will spend several hours in the recovery room. The procedure can be performed under local or general anesthesia, depending on the location of the nerve.
Rhizotomy can effectively reduce muscle spasms by severing the nerve fiber roots that deliver nerve impulses to the muscles. This interrupts the signals that cause the spasms, providing relief from pain and improving mobility. The procedure is considered safe and reliable, with a low risk of complications.
It is important to note that the nerve will regrow over time, and the pain may gradually return. In such cases, patients can consult their doctors to determine if a second rhizotomy or another treatment option is more suitable. Additionally, intensive follow-up rehabilitation and physical therapy are necessary to achieve the best possible results and prevent potential complications.

Rhizotomy is a safe, efficient and minimally invasive treatment
Rhizotomy is a safe, efficient, and minimally invasive treatment for chronic pain. It is a last-resort procedure for patients who have not found relief from pain through medication or physical therapy. The treatment involves damaging certain nerve fibres to prevent them from sending pain signals to the brain. Rhizotomy can be performed on the spinal cord or other joints in the body, and it can be carried out under local or general anaesthesia.
There are several types of rhizotomy procedures, including:
- Open surgery involves cutting the nerves with a surgical instrument.
- Endoscopic approach uses a tiny incision and a small camera tool to locate and cut the nerves.
- Chemical ablation damages the nerves with chemicals like glycerin or glycerol.
- Radiofrequency ablation burns the nerves with focalized high-intensity radio waves.
- Direct visualized rhizotomy uses an endoscope (a small camera device) to locate and sever the affected nerve fibres.
Rhizotomy is a safe and effective treatment for managing pain and improving patients' quality of life. It can provide instant pain relief that typically lasts for several years, until the nerve heals and can transmit pain signals again. Rhizotomy can also help reduce muscle spasms by cutting off the signals that cause them.
While rhizotomy is considered safe and minimally invasive, it is important to note that it does carry some risks and potential complications, such as sensory changes, muscle weakness, and allergic reactions to anaesthesia. Additionally, the procedure may not offer a 100% success rate, and the nerve will regrow over time, requiring further treatment.

Rhizotomy can be performed using surgery, chemicals or radiofrequency ablation
Rhizotomy is a procedure that involves damaging certain nerve fibres to treat chronic pain or spasticity. It is not the first-choice treatment for chronic pain. Healthcare providers will recommend more conservative treatments first, such as physical therapy, pain medication, NSAIDs or nerve blocks.
There are several different types of rhizotomies, and the procedure can be performed using surgery, chemicals, or radiofrequency ablation. With surgery, doctors can use either open surgery, which involves a large incision, or endoscopic surgery, which involves a tiny incision and a small camera tool to locate the nerves and cut them.
Chemical ablation involves damaging nerves using a toxic substance, such as glycerin or glycerol. This method has a lower likelihood of causing sensory changes (feelings of numbness) than radiofrequency ablation.
Radiofrequency ablation (RFA) is a way of damaging nerves using heat. It involves burning the nerves with focalised high-intensity radio waves.
The majority of people who have a rhizotomy experience long-lasting pain relief or significant improvement in spasticity. However, it is important to note that the procedure does not offer a 100% success rate, and a small percentage of people may feel little to no pain relief.

Rhizotomy is used to treat spasticity in children with cerebral palsy
Rhizotomy is a surgical procedure that involves damaging certain nerve fibres to treat chronic pain or spasticity. It is a pain management technique that can be performed in several ways, including surgical cutting, chemical ablation, or radiofrequency ablation. The procedure is typically considered a last resort when other methods, such as pain medication and physical therapy, have been unsuccessful.
Selective dorsal rhizotomy (SDR) is a type of rhizotomy that is specifically used to treat spasticity in children with cerebral palsy. Spasticity is a common symptom of cerebral palsy, causing certain muscles to contract all at once, affecting mobility and causing pain. SDR targets the sensory nerve fibres in the lower spinal cord that are responsible for muscle tightness in the legs. By cutting or deadening these specific nerve fibres, SDR can reduce spasticity and improve communication between the spine and muscles. This, in turn, helps to prevent muscle scarring and joint and bone deformities that can develop in children with cerebral palsy if spasticity is left untreated.
While SDR can be an effective treatment for spasticity in children with cerebral palsy, it is not a common surgery and is only performed in a limited number of hospitals. Not all children with cerebral palsy are candidates for SDR, and a screening process is necessary to determine if the surgery will be beneficial. The procedure requires intensive follow-up rehabilitation and physical therapy, and the child will need to lie flat for the first one to three days after surgery.
The rhizotomy procedure itself takes only a few minutes, but it requires general anesthesia and a hospital stay of four to five days. After surgery, children typically begin physical therapy several times a week for six weeks or longer. Rhizotomy does not offer a 100% success rate, and there is a chance that pain may return after several years as the nerve regrows. However, it has been shown to improve mobility and function, helping children with cerebral palsy increase their independence and quality of life.
