Value of Functional Anesthetic and Provocative Discography in the Surgical Treatment of Discogenic Pain

2014-08-27 03:15:35 | BioPortfolio


Although discography and spinal imaging techniques, either alone or in combination, are commonly used to diagnose discogenic pain, their exact role in predicting surgical results are poorly defined. Our aim in this study is to compare the ability of Functional anesthetic discography (FAD), and Provocative Discography (PD) to diagnose discogenic pain and to correctly identify the disc levels for the surgical treatment. Proper identification for disc levels should improve the overall results of surgery for this condition. Patients with discogenic pain have better outcomes if the disc levels for the fusion surgery are identified by using FAD compared to similar disc level identification by PD.

Medical and Biotech [MESH] Definitions

Inflammation of an intervertebral disk or disk space which may lead to disk erosion. Until recently, discitis has been defined as a nonbacterial inflammation and has been attributed to aseptic processes (e.g., chemical reaction to an injected substance). However, recent studies provide evidence that infection may be the initial cause, but perhaps not the promoter, of most cases of discitis. Discitis has been diagnosed in patients following discography, myelography, lumbar puncture, paravertebral injection, and obstetrical epidural anesthesia. Discitis following chemonucleolysis (especially with chymopapain) is attributed to chemical reaction by some and to introduction of microorganisms by others.

Procedure in which an individual is induced into a trance-like state to relieve pain. This procedure is frequently performed with local but not general ANESTHESIA.

Drugs administered before an anesthetic to decrease a patient's anxiety and control the effects of that anesthetic.
