Abstract

A psoas compartment block has been used to provide anesthesia for orthopedic surgical procedures and analgesia for post-operative pain. Currently, this block is advocated for relieving pain in the lower extremity and pelvic area resulting from various origins. We report a case of a 69-year-old male patient who had gait abnormality with posterior pelvic and hip pain, which were both aggravated by hip extension. From the magnetic resonance image, the patient was found to have a laterally herniated intervertebral disc at the L2/3 level, which compressed the right psoas muscle. This was thought to be the origin of the pain, so a psoas compartment block was performed using 0.25% chirocaine with triamcinolone 5mg, and the pain in both the pelvis and hip were relieved.
