According to studies, approximately 30% of the patients who undergo surgery for degenerative spine disease do not achieve the desired results. This residual or worsened pain after spinal surgery is notoriously difficult to treat.
Chronic back pain is a serious condition affecting millions of people worldwide. It can affect your ability to work, play with your kids, or even just enjoy a good night's sleep. For many people, lumbar spine surgery can be a solution to this problem, but some patients still experience pain after the surgery.
It is estimated that up to 50,000 patients currently undergo spinal cord stimulation treatment per year worldwide, and one of the most common indications is persistent radicular pain following lumbar spine surgery. While the use of spinal cord burst stimulation is increasing, rigorous clinical evidence of its efficacy is lacking.
Clinical TrialA clinical trial has aimed to investigate the efficacy of spinal cord burst stimulation in patients with chronic radiculopathy after surgery for degenerative lumbar spine disorders.
The trial involved 50 patients who had chronic radicular pain after lumbar spine surgery. Radicular pain is a type of pain that radiates from the spine to other parts of the body, such as the legs or arms. The patients underwent two 3-month periods with spinal cord burst stimulation and two 3-month periods with placebo stimulation in a randomized order.
Spinal cord burst stimulation involves implanting electrodes near the spinal cord and using them to deliver electrical pulses to the nerves that transmit pain signals. This can help to interrupt the pain signals and reduce the amount of pain that a person experiences.
