- Patient: male; 48 years old
Treatment history: Previous treatment consisted of analgesics, physical therapy, and a sacroiliac belt. The pain was diagnosed as sacroiliac in origin, but was unable to wear the belt due to increased discomfort.
Physician evaluation: Points of spontaneous pain involved the upper half of the buttock as far as the sacroiliac joint medially and the anterior thigh. These points were within a zone of tenderness which involved the T12, L1 and L2 dermatomes. There was trunk tenderness paravertebrally at points corresponding to the peripheral distribution.
Resolution: Paravertebral infiltration at these levels caused immediate cessation of pain. There was no recurrence 4 years after the first injection.
