An impar block is a type of injection that can be used to treat pain in the lower pelvis and groin. It involves injecting a local anesthetic or steroid medication into the ganglion impar, which is a cluster of nerve cells located at the base of the spine.
The ganglion impar is responsible for transmitting pain signals from the lower pelvis and groin to the brain. By blocking the ganglion impar, the injection can interrupt these pain signals and provide temporary relief.
Impar blocks are typically used to treat pain caused by these conditions:
Impar blocks are typically performed in an outpatient setting. The procedure usually takes about 30 minutes to complete.
Before the procedure, patients are asked to lie on their stomach on an X-ray table. The area where the injection will be given is cleaned and numbed with a local anesthetic.
The doctor will then use a fluoroscope—a type of X-ray machine—to guide a thin needle to the ganglion impar. Once the needle is in place, the doctor injects a local anesthetic and/or steroid medication.
The local anesthetic numbs the nerves in the ganglion impar, which will temporarily relieve pain. The steroid medication will reduce inflammation and may provide longer-lasting pain relief.
Impar blocks can provide several benefits, including:
Impar blocks are generally safe procedures. However, there are a few potential risks.
After an impar block, patients may experience some temporary discomfort at the injection site. They may also experience some temporary numbness or weakness in the area where the injection was given.
Patients are typically able to go home after the procedure. However, they may need to have someone drive them home because the local anesthetic may impair coordination.
Patients should avoid strenuous activity for 24 hours after the procedure. They should also avoid taking any blood thinners, such as aspirin or warfarin, for 24 hours after the procedure.
Impar blocks can be an effective treatment for a variety of pain conditions in the lower pelvis and groin. They're generally a safe procedure with few risks.
