How are degenerative disc disease, radiculopathy, and sciatica diagnosed?

Degenerative disc disease, radiculopathy, and sciatica are suspected when the symptoms described above are noted. The doctor can sometimes detect signs of irritated nerves during the examination. For example, increased radiating pain when the lower extremity is lifted supports the diagnosis of lumbar radiculopathy. Nerve testing (EMG/electromyogram and NCV/nerve conduction velocity) of the lower extremities can be used to detect the nerve irritation. The actual disc herniation can be detected with radiology testing, such as CAT or MRI scanning.

How is radiculopathy treated?

The treatment of degenerative disc disease, radiculopathy, and sciatica ranges from nonsurgical (medical) management to surgery. Medical management of radiculopathy includes patient education of the condition, medications to relieve pain and muscles spasm, cortisone injection around the spinal cord (epidural injection), physical therapy (heat, exercises, massage, ultrasound, electrical stimulation), and rest (not strict bed rest, but avoiding reinjury). With unrelenting pain, severe impairment of function, or incontinence (which can indicate spinal cord irritation), surgery may be necessary. The operation performed depends on the overall status of the spine and the age and health of the patient. Procedures include removal of the herniated disc with laminotomy (producing a small hole in the bone of the spine surrounding the spinal cord), laminectomy (removal of the bony wall adjacent to the nerve tissues), by needle technique through the skin (percutaneous discectomy), disc-dissolving procedures (chemonucleolysis), and others.
