The benefits from the first shot only lasted 2 weeks. The second and third set of injections lasted about 90 days. In November, I was ready to have surgery. My EMG and nerve conduction tests proved that the nerves were "sleeping" before I was. After another MRI, the neurosurgeon said I was a candidate for surgery but I was not able to get the endoscopic type surgery that is less invasive. I would have an incision about 6-8" long. Along with removing the herniation, they would have to increase the size of the hole where the nerve roots were going through.
When the disease is in its chronic form -as it usually happens after spine surgery or following the acute and subacute phase of radiculitis from disc herniation that had been undertreated with conservative therapy- neuroplasty (adhesiolysis) with Racz catheter is indicated.
The American Society of Interventional Pain Physicians (ASIPP) published evidence-based guidelines for invasive techniques in the management of chronic spinal pain.
According to these guidelines, there is strong evidence indicating the efficacy of neuroplasty with corticosteroids in the short and long-term control of pain in refractory radiculopathy and neuropathic spinal pain.
