What is dorsal rhizotomy surgery?

What is dorsal rhizotomy surgery?

Selective dorsal rhizotomy (SDR) is a surgery done on the lower spinal cord to reduce spasticity (high muscle tone) in the legs. Certain abnormal nerve fibers that cause high muscle tone are cut. The goal of SDR is to relax the muscles by identifying and cutting only those nerve fibers that contribute to spasticity.

Who is a candidate for selective dorsal rhizotomy?

Primary candidates for SDR are children who have muscle spasticity in their legs that limits their mobility, but have little spasticity in their arms and are generally otherwise well. The procedure, combined with physical therapy, can greatly improve mobility for these children.

How is a selective dorsal rhizotomy performed?

Selective dorsal rhizotomy is a surgical procedure performed on the lower spinal cord. The nerves are separated then identified via an electrical stimulation. Following identification, certain sensory nerve fibers in the spinal cord are cut.

How long is selective dorsal rhizotomy surgery?

SDR takes about four hours at Nationwide Children’s. A surgery nurse will come out from time to time to give you updates on your child’s operation. It involves the following steps: The surgeon makes a 1- to 2-inch cut along the lower backbone.

Can adults have selective dorsal rhizotomy?

Adults 25 years and younger will undergo selective dorsal rhizotomy (SDR) at St. Louis Children’s Hospital and will follow their protocol. The adult patient over the age of 25 will undergo SDR at Barnes-Jewish Hospital. Approximately 24 hours will be spent in the Neurology/Neurosurgery Intensive Care Unit.

Is rhizotomy a major surgery?

The rhizotomy can be repeated, if needed. Rhizotomy is a minimally invasive procedure, so it is usually performed in an outpatient surgical center. Heat is used to burn the nerve roots that are causing the back pain.

Is SDR surgery painful?

Children undergoing SDR are postoperatively in severe pain, a pain related to both the extensive surgical exposure with multilevel laminectomy and the nerve root manipulation.

How long does a dorsal rhizotomy take?

Selective dorsal rhizotomy surgery takes about four hours. Your child will be under general anesthesia. A nurse will talk with you during surgery to let you know how things are going. During the surgery, the neurosurgeon will make a one-inch incision to access the lower spine.

Who performs SDR surgery?

Neurosurgeons typically perform SDR after removing the lamina ( laminectomy ) from 5-7 vertebrae. That technique was also used at the St. Louis Children’s Hospital Cerebral Palsy Center to perform SDR on over 140 children with CP.

How painful is a rhizotomy?

Most patients feel pressure but do not experience pain during a rhizotomy. The surgical site will be numbed using local anesthesia. A 1/4-inch incision will be made near the facet joint of the vertebrae.

What can go wrong with a rhizotomy?

The risks associated with rhizotomy depend on the type of the procedure and which nerves it’s performed on. Glycerin/glycerol rhizotomy risks include bleeding, infection, nausea, vomiting, a small chance of sensory change (feeling of numbness) and anesthesia complications.

How many times can you have a rhizotomy?

The pain relief induced by this procedure may last anywhere from six months to two years. Unfortunately, the nerve will eventually grow back and that may lead to a return of previous pain levels. The procedure can be repeated every six to eight months, if necessary.

Do they put you to sleep for a rhizotomy?

Type of Anesthesia – Most rhizotomy procedures are done under general anesthesia. You will be asleep during the procedure and will not be aware of what is going on. If you undergo rhizotomy using chemicals like glycerol injection, you will be sedated with intravenous medications.

What is the success rate of a rhizotomy?

Endoscopic rhizotomy patients report a 90% success rate with up to 5 years of pain relief.

What should you not do after a rhizotomy?

After a rhizotomy, patients can usually return to work and normal activities the next day, but should avoid any strenuous activity or heavy lifting for a day or two. Taking a shower is permitted but bathing, swimming, or soaking in a hot tub should be avoided for the next 24 hours.

What is a selective dorsal rhizotomy?

What Does Selective Dorsal Rhizotomy Involve? A selective dorsal rhizotomy is a surgery that involves cutting sensory nerve fibers, typically in the L2 to S1 levels of the spinal cord to reduce the hyperexcitability of spastic muscles in the legs.

What are the risks of a dorsal rhizotomy?

The dorsal rhizotomy is a complicated neurosurgical procedure. As in other major neurosurgical procedures, it carries risks. Paralysis of the legs and bladder and sensory loss are the most severe complications. Wound infection and meningitis are also possible.

Does dorsal rhizotomy worsen hip subluxation in children?

In most patients, selective dorsal rhizotomy can halt the progression; certainly it does not exacerbate or increase the risk of hip subluxation. However, some children under 5 years of age who have poorly developed hip joints do show progression of hip subluxation regardless of treatment.

What are the benefits of dorsal rhizotomy for spasticity?

When there is less spasticity to deal with, parents find it easier to change a diaper or use an adaptive feeding device, for example. For reasons that are not clear, selective dorsal rhizotomy sometimes results in better breath, arm and head control as well as lessened leg spasticity.
