ONS Advance Access: Long-Term Reduction of Sacroiliac Joint Pain With Peripheral Nerve Stimulation

Low back pain is a common disorder, causing long-term disability among a large proportion of the population in the developed world. Work force loss caused by pain in the lower back ranges between 2% and 4%.1 The lifetime risk of developing pain in the lower back is close to 14%.2 Sacroiliac joint (SIJ) pain contributes about one-fifth of all patients with pain in their lower back.3-5 It has been estimated via compared diagnostic injections that 10% to 38% (false positive rate of 0%-53.8%) of back and leg pain originates from the SIJ.5

SIJ pain is usually perceived in the buttocks, but pain can radiate toward the legs or the lower back.6,7 The diagnosis is usually confirmed by pain reduction after anesthetizing the SIJ.8

Nonsurgical therapy for chronic SIJ pain includes oral administration of anti-inflammatory and analgesic medications, repetitive intraarticular injection of corticosteroids, and physical therapy.9 If conventional treatments fail, then radiofrequency or cryoablation of the lateral branches of S1 to S3 can be performed.7, 10 SIJ arthrodesis may be considered if all known treatments fail.11
