Radiculopathy is a condition where a nerve root in the spine is compressed, producing pain or weakness across the whole length of the nerve. It is sometimes referred to as a pinched nerve or sciatica. It occurs most commonly, but is not limited, to the lower back and neck. Dr. William Ryan Spiker is a fellowship-trained Orthopaedic and Neurologic spine specialist who treats conditions of the neck and back such as disc herniations, spinal stenosis, cervical myelopathy, and deformities of the spine. He believes in the thoughtful use of new technologies, including minimally invasive surgery and image-guided techniques for the betterment of patients. Dr. Spiker provides diagnosis and individualized management for neck pain in Utah. Contact Dr. Spiker’s team for an appointment today!
Spinal Cord Anatomy
The spinal cord is made up of a bundle of spinal nerves that run down the vertebral column, extending from the neck to the lower back. The spinal cord functions as a message carrier between the brain and different parts of the body and are protected from injury by the bones of the vertebral column.
What is Radiculopathy?
Certain diseases or mechanical compression of these spinal nerves due to deformities in the vertebral column can lead to radiculopathy.
Radiculopathy is a condition where a nerve root in the spine is compressed, producing pain or weakness across the whole length of the nerve. It is sometimes referred to as a pinched nerve or sciatica. It occurs most commonly, but is not limited, to the lower back and neck.
Causes of Radiculopathy
Spinal nerves are compressed when the space in the spinal canal is reduced. This reduction of space in the spinal canal can occur due to:
- Herniation of the discs in the vertebral column
- A bone spur or outgrowth of bone due to osteoarthritis
- Thickening of surrounding ligaments
- Abnormal curvature of the spine from scoliosis
- Diabetes, which can reduce blood flow to the nerves
- Inflammation due to degeneration or trauma
Signs and Symptoms of Radiculopathy
Pain, numbness and tingling sensation are common symptoms of radiculopathy. Pain can be felt either locally at the nerve injury site, or farther from the point of injury in the arms and legs.
The place where the symptoms are felt depends on the region of nerve injury on the spinal cord. Sensation or pain can be felt in the neck, arms, or legs if the nerves of the neck, thorax, or lower back are injured.
Some patients can develop hypersensitivity when the affected region is touched or weakness of the muscles due to nerve damage.
Diagnosis of Radiculopathy
Your doctor diagnoses radiculopathy after reviewing your medical history to localize the point of injury. A physical examination will be performed to determine sensation, muscle strength and reflexes. Additionally, imaging studies will be ordered including:
- X-rays to identify infection, osteoarthritis, trauma and early signs of a tumor
- MRI or CT scan, to check the surrounding soft tissues and location of nerve compression
- Nerve conduction study and electromyogram, to measure the electrical activity of the nerve
Treatment of Radiculopathy
Your doctor will first suggest conservative treatments such as muscular rehabilitation, medication and interventional therapy typically in the form of an epidural injection. Epidural steroid injection will be administered between the bones of the spine where the nerve is damaged, guided by X-ray imaging.
Surgical treatment may be recommended based on your presentation and response to conservative care.
Surgery to Treat Radiculopathy
Depending on the cause of the nerve damage, your surgeon will perform a decompression surgery and may include spinal fusion of the vertebrae. Through the corresponding procedures, the part of the bone or herniated disc pressing against the nerve is removed to make more room for the nerve, and release the compression. Surgeries are performed under general anesthesia.
