Discography A discogram, also known as disc stimulation, is a brief outpatient diagnostic procedure that is performed in order to identify painful discs in the spine. If the pain is the same this may indicate a diseased disc. If pain is provoked between 51 and 90 psi 346. Using patients who underwent spinal fusion for unstable lumbar spondylolisthesis as controls and adjusting for surgical morbidity and dropout, the best-case positive predictive value of discography was calculated to be 50—60%. If the tear is extensive, the contents of the disc can leak out and can be very irritating to the surrounding tissue, contributing to that pain. Got state of the art custom fitted splint that made life easy and they put my mind at ease. Supporters for the use of discography counter these points through a number of studies.
Discitis usually results in very intense pain but can be treated with antibiotics. Lastly, there were notable errors in the accounting of the data. Because it's important to describe sensations felt during the procedure, the patient remains conscious. Discography is usually done only if you think your pain is significant enough for you to consider more advanced treatment options, directed at the disc itself, such as surgery. Under fluoroscopy, clinicians place a needle via a right paramedian approach. Doctors may administer intravenous sedation to make patients more comfortable. Repetitive twisting increases the susceptibility for microtears of annulus, which is one of the beginning pathways for degenerative disc changes.
Discography may be uncomfortable, but it may provide valuable information that helps the physician pinpoint the pain-generating disc. The patient is asked about any sensations felt upon the injection. If the needle is inserted into a disc that is not the cause of ongoing pain, then you should not feel any discomfort. First, the soft tissues of the right neck and vascular structures are manually displaced laterally, while the esophagus and trachea is deviated medially. Local anesthesia is administered to numb skin and tissue over the discs being tested.
You may be given pain medication to alleviate discomfort. Fortunately, there are treatments available to address many conditions with chronic pain, and some of these treatments use orthobiologics. Your soreness should improve by the third day and your pain should go back towards your baseline level. Plavix ® and Aggrenox ® are stopped 1 week prior to the procedure to avoid bleeding. The end plate articulates with the disc and the vertebral body. If the cause of your typical symptoms is a painful disc in your spine, then this pain will likely be reproduced during disc stimulation.
Increased intra-discal pressure may replicate your symptoms eg, leg pain. He performed the first discography when he injected red lead contrast into a cadaveric disc. Typical symptoms related to disc degeneration are neck or back pain and sometimes pain in the lower limbs. This information may be used to determine if surgery may be benefi cial. Prior to conducting a discogram, clinicians must assess discs cephalic and caudal to the level of pathology in addition to a normal control disc.
Discography might prove effective for clinicians treating patients who have tried treatment modalities, such as modified activities, medications, physical therapy, injection procedures, and other conservative methods. History and controversy of discography During the 1940s and 1950s, many researchers conducted studies that answered questions regarding the pathophysiology of lumbar and cervical disc disease. A normal thoracic disc accepts around 0. None of the asymptomatic patients had significant pain with dye injection. The health care provider performing the discographic injections will likely talk to you about your symptoms and the details of the procedure. It is extremely important for you to be awake enough to tell your doctor what you are feeling during this procedure.
There is a risk of complications associated with discography. Pain provocation is crucial before further interpretation of imaging findings. This injection is guided by a Fluoroscopy machine. Movements in the cervical and lumbar regions include flexion, extension, rotation, and lateral bending. Discogram is another term for discography.
P1 response is a partial positive response and P2 is a negative response. Ordering the procedure depends on access to a skilled discographer. Both plexuses ultimately supply the annulus fibrosus with nerve innervation. Intervertebral discs connect the inferior and superior vertebral bodies. These difficult cases require supplemental diagnostic studies.
