Lumbar Discogram

PREOPERATIVE DIAGNOSIS: Low back pain.

POSTOPERATIVE DIAGNOSIS: Low back pain.

PROCEDURE PERFORMED:
1. Lumbar discogram L2-3.
2. Lumbar discogram L3-4.
3. Lumbar discogram L4-5.
4. Lumbar discogram L5-S1.

ANESTHESIA: IV sedation.

PROCEDURE IN DETAIL: The patient was brought to the Radiology Suite and placed prone onto a radiolucent table. The C-arm was brought into the operative field and AP, left right oblique and lateral fluoroscopic images of the L1-2 through L5-S1 levels were obtained. We then proceeded to prepare the low back with a Betadine solution and draped sterile. Using an oblique approach to the spine, the L5-S1 level was addressed using an oblique projection angled C-arm in order to allow for perpendicular penetration of the disc space. A metallic marker was then placed laterally and a needle entrance point was determined. A skin wheal was raised with 1% Xylocaine and an #18-gauge needle was advanced up to the level of the disc space using AP, oblique and lateral fluoroscopic projections. A second needle, #22-gauge 6-inch needle was then introduced into the disc space and with AP and lateral fluoroscopic projections, was placed into the center of the nucleus. We then proceeded to perform a similar placement of needles at the L4-5, L3-4 and L2-3 levels.

A solution of Isovue 300 with 1 gm of Ancef was then drawn into a 10 cc syringe and without informing the patient of our injecting, we then proceeded to inject the disc spaces sequentially.
