Embodiment 1
[0096] Fluoroscopy-guided intradiscal injection
[0097] [0095] After sterile preparation, the introducer needle is projected obliquely into the superior articular process. A curved spinal needle is passed through the guide needle and into the disc. Fluoroscopic projections in both anteroposterior and lateral directions are used to confirm proper needle placement. If needle placement needs to be adjusted, then again confirm placement by fluoroscopy. A contrast agent (contrast medium) is injected to confirm needle placement. In patients with chemical radiculitis, leakage of contrast material through annular fissures and / or intradiscal lesions can be observed and thus identified. Once the needle is properly placed in the intradiscal space, the fibrin sealant (or its components) is injected using the injector system of the present invention with a pressure monitor. Monitor the pressure to ensure that the disc is not overstressed. Watch the fibrin sealant to force the contras...
