About

Sacral lateral branch blocks are used for the diagnosis and treatment of sacroiliac joint pain. This study will compare ultrasound and fluoroscopy guidance for sacral lateral branch blocks. Outcomes examined will include performance times and success rates.

Enrollment: 40 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Any consenting patient over 18 years of age, undergoing a diagnostic sacral lateral branch block for suspected sacroiliac joint related pain.

Exclusion criteria

• Inability to consent, iodine or lidocaine allergy, pregnancy, coagulopathy (as defined by an international normalized ratio over 1.4, platelets under 100,000, or a documented bleeding disorder) and inability to visualize the target areas necessary for sensory testing (posterior superior iliac spine, dorsal aspect of SIJ) under ultrasound guidance.
