Injections are made into the joint between the top of the triangular bone at the base of the spine and the base of the tailbone (the sacroccygeal junction).
When hard-to-pin-down lower back pain is accompanied by a dull ache high in the rectum, this kind of injection may confirm or disprove whether the patient’s pain is caused by coccydynia, a condition caused by impact to the tailbone.
During the Procedure
The patient lies facedown on an x-ray table while numbing medication and then steroids are injected into the into the sacroccygeal junction using fluoroscopic guidance for precise delivery. The procedure takes 15 to 30 minutes, with about 45 minutes recovery. Discomfort during the procedure should be minimal.
If a patient desires further sedation, that is certainly available. Usually this isn’t necessary and sedation does increase recovery time. Whether or not the patient is sedated, Dr. Dumitru requires that after a coccygeal block, a patient be driven home.
Patients are advised to take it easy and not return to work or other taxing activities until the next day.
Usually a coccygeal block will provide significant relief for individuals who are suffering from tailbone pain.
