Ganglion Impar Block

What is a Ganglion Impar Block?

A Ganglion Impar block is a medical procedure that involves the injection of a local anesthetic near the ganglion of Impar, a small bundle of nerves located at the level of the coccyx (tailbone). By blocking these nerves, the procedure can effectively relieve pain in the pelvic and perineal regions.

What Can It Treat?

The Ganglion Impar block is used to treat a variety of chronic pain conditions, including but not limited to:

Coccydynia (tailbone pain)

Perineal pain

Chronic pelvic pain

The procedure can be an effective way to manage pain for those suffering from these conditions, especially when other conservative treatments have failed.

How is the Ganglion Impar Block Administered?

The procedure is performed with the patient lying face down or in a prone position. Using fluoroscopic or ultrasound guidance, I locate the ganglion of Impar, and then:

Preparation: The area is cleaned and sterilized.

Anesthetic: A local anesthetic is used to numb the area.

Injection: A needle is guided to the targeted area, and the blocking agent (usually a mixture of a local anesthetic and sometimes a steroid) is injected.

Monitoring: After the procedure, the patient is monitored for a brief period to ensure no immediate complications arise.

What are the Risks?

While the Ganglion Impar block is considered safe and is usually well-tolerated, as with any medical procedure, there can be risks and side effects:




Temporary increase in pain

Allergic reaction to the medication
