title: Spinal balloon nucleoplasty: a hypothetical minimally invasive treatment for herniated nucleus pulposus.
abstract: Low back pain is the most common cause of disability under the age of 45. The annual incidence of back pain is estimated to be 5% and the lifetime prevalence is 80%. Majority of the patients with persistent symptoms are suffering from radiculopathy that is mainly caused by a herniated nucleus pulposus (HNP). HNP can heal spontaneously due to spontaneous resorption. Besides pressure nucleus pulposus, without any compression, may induce similar changes when applied epidurally to the nerve roots. Nevertheless, combination of chronic mechanical compression and application of nucleus pulposus causes a more pronounced nerve injury. When dual pathophysiology (pressure and inflammatory reaction), spontaneous resorption, and natural course of HNP are taken into account, any treatment modality that eliminates both the pressure and contact of the nucleus pulposus with the nerve root via creating extra time for healing to take place might prove beneficial. These requirements can be provided by spinal balloon nucleoplasty (SBN), which can be used in combination with other treatment modalities such as chymopapain injection. In this hypothetical method, epidural access to the subarachnoid space is established via epidural needles, thereafter a specially designed balloon tipped catheter is advanced. When the catheter is ideally placed with the help of CT or MRI, the balloon at the tip is inflated to relieve pressure and to prevent contact of the nerve root with HNP. The answer to the question, will SBN find a place in clinical practice? is obscure. But a homology can be established with uterine fibroid embolization, which has found clinical use in a period of 30 years approximately.
