Coblation of femoral and sciatic nerve for stump pain and phantom limb pain
Phantom limb pain is a common problem in people who have an amputed limb. Phantom pain often begins within a few days after surgery. Some people find that phantom pain and sensations decreases over time where as others may experience the pain for many years. Pain that hos gone untreated for more than a year tend to be more difficult to treat. As well as pain in the absent limb, people can also experience pain in the stump.
There is currently no reliable treatment for stump pain and phantom limb pain. However peripheral factors play s significant role in the pathophysiology of stump pain and phantom limb pain. New advancements have been made for the treatment of stump pain and phantom pain. One of the recent developed is coblation technology, that has shown promising results in treating the neuropathic pain.
A study has been conducted for the trial of coblation technology for treating the stump pain and phantom limb pain. This report described the use of coblation technology on femoral and sciatitic nerve for stump pain and phantom limb pain. An ultrasound guided perineural infiltration anesthesia surrounding the neuroma was first performed and achieved approximately up to 60% pain relief that lasted for 2 hours. But no reduction was seen in the phantom limb pain.
Further, an ultrasound guided femoral and sciatic nerve block was performed to obtain longer pain relief. Significant reduction was observed up to 80% of pain in both stump pain and phantom limb pain that lasted for 40 hours. Addition of other factors to the ultrasound detected neuroma in the residual limb generating pain has proven to be effective after performing coblation of femoral and sciatic nerves.
After the completion of randomized trial, it was evaluated that stump pain was completely relieved imeediately after operation. Overall activity was also improved and further no pain medications were prescribed with stable analgesic effects. Coblation technology has proven to be a useful treatment for stump pain and phantom pain. Whereas, additional study confirmation is needed for the treatments focusing on peripheral nerves that may be more effective than those focusing on the neuroma.
