Pain Management – PSIS Injection and PSIS Neurotomy
The Posterior Superior Iliac Spine (PSIS) is the section of the hip to which major ligaments attach. These ligaments help support the hip and lower back. A PSIS injection may be used to help evaluate pain in this area.
What is PSIS Injection?
A PSIS injection is used to help diagnose pain in the PSIS region, which may be related to inflammation or dysfunction in this area of the body. The benefit of a PSIS injection is to help better understand the source of pain and assist in determining appropriate next steps in care.
How is a PSIS Injection performed?
Under the guidance of fluoroscopy (X-ray guidance), a diagnostic needle is placed into the PSIS and a local anesthetic is injected.
If, during two different occasions, you experience a temporary change in pain, it may suggest that the PSIS is contributing to the symptoms. This information can help guide whether a radiofrequency PSIS neurotomy may be considered.
What is Radiofrequency PSIS Neurotomy?
Radiofrequency PSIS neurotomy is a nonsurgical procedure that targets small nerves near the PSIS that may contribute to pain signaling.
During the procedure, a provider places a probe next to the nerves and delivers a controlled electrical current. This current creates heat, which affects the targeted nerve. However, surrounding tissue is generally preserved.
Providers may consider this procedure after a PSIS injection, depending on individual findings. Still, outcomes can vary from patient to patient.
What to Expect After a PSIS Injection
After a PSIS injection, patients remain under observation for a short period before leaving the facility.
In addition, patients need a driver on the day of the appointment because minimal sedation may be used.
