Lumbar radiculopathy refers to lower back and leg pain that derives from pressure on the nerve roots as they exit the spinal column. The pressure on the nerve root is often the result of damage to the discs in between the vertebrae that make up the spine where the central softer portion of the disc can rupture through the outer ring of the disc. The main causes of lumbar radiculopathy include degenerative disc disease, disc herniation (herniated or ruptured discs), and spinal trauma.
Signs and Symptoms of Lumbar Radiculopathy
Pressure on the nerve roots leads to sensory symptoms like tingling and numbness, which in many cases grow more severe over time. Some patients experience dull aches or radiating pain from the back to the buttocks and down to the legs and feet, which is a condition known as sciatica. Motor symptoms (like muscle weakness) and incontinence of the bladder and/or bowels are usually signs that the nerve compression is more severe.
Lumbar Radiculopathy Diagnosis
The correct diagnosis of lumbar radiculopathy begins with a complete history , physical exam and a consultation to evaluate a patient’s history of symptoms. Nerve testing (EMG/electromyogram and NCV/nerve conduction velocity) of the lower extremities can be used to detect nerve irritation. Actual disc herniation can be detected with radiology testing, such as CT Myelography(computed tomography) or MRI (magnetic resonance imaging) scanning.
Treatment for Lumbar Radiculopathy
Typically, non surgical treatment is pursued as first-line lumbar radiculopathy treatment. Medical management may include medications, cortisone injections around the spinal nerve roots, physical therapy (heat, massage, ultrasound, electrical stimulation), and rest to avoid re-injury. In cases of extreme pain, severe impairment of function, or incontinence, surgery may be necessary. Minimally invasive spinal surgery, such as laminectomy, percutaneous discectomy, may prove effective in alleviating the pressure and resolving lumbar radiculopathy pain. If you are diagnosed with lumbar radiculopathy, your doctor will explain treatment options to you and help you decide what course of action is best to help you get back the quality of life you expect. |
