[Injection therapy of the spine without imaging].

Nerve root blocks and epidural perineural injections are main part in the conservative treatment of degenerative spine diseases. These injections should be done without imaging because degenerative spine diseases - discogenic oder spinal stenotic - tend to recurrence and danger arises from too many imaging with cumulative ionizing radiation over the years, especially in younger people. After certain training it is possible to perform spinal injections without imaging only considering topographic anatomical landmarks like in any other local anesthesia for surgical reasons. Repetitive periradicular injections desensitize the nerve root by local anesthetics and reduce its inflammatory swelling by steroids. The decompensated symptomatic deformity turns back into an asymptomatic compensated status.
