The sacroiliac joint (SIJ) is a putative source of low back pain. The objective of this article is to provide clinicians with a concise review of SIJ structure and function, diagnostic indicators of SIJ-mediated pain, and therapeutic considerations. The SIJ is a true diarthrodial joint with unique characteristics not typically found in other diarthrodial joints. ⋯ Conservative management includes manual medicine techniques, pelvic stabilization exercises to allow dynamic postural control, and muscle balancing of the trunk and lower extremities. Interventional treatments include sacroiliac joint, intra-articular joint injections, radiofrequency neurotomy, prolotherapy, cryotherapy, and surgical treatment. The evidence for intra-articular injections and radiofrequency neurotomy has been shown to be limited in managing sacroiliac joint pain.

Does adherence monitoring reduce controlled substance abuse in chronic pain patients?
Opioids are used extensively for chronic pain management in the United States. The frequency of opioid use prior to presenting to interventional pain management settings and in interventional pain management settings has been shown to be above 90%. Given that controlled substance abuse and illicit drug use are prevalent phenomena, adherence monitoring of patients that are prescribed opioids is becoming common. Adherence monitoring is carried out by an appropriate history, periodic evaluation of appropriate intake of drugs, random drug testing, and pill counts. Crucial to adherence monitoring is an initial controlled substance agreement and repeated review of the terms of this agreement with on-going education. However, the effect of adherence monitoring on drug abuse is unclear. ⋯ Adherence monitoring, including controlled substance agreements and various periodic measures of compliance was associated with a 50% reduction in opioid abuse.

The role of nonspecific treatment effects in the outcomes of patients receiving interventions for pain has been the subject of controversy and interest. While the administration of placebo and its effects have been widely studied, the role of placebo and nocebo effects of active agents administered prior to or during interventional techniques has not been explored. ⋯ In patients undergoing interventional procedures, sodium chloride solution, midazolam, and fentanyl produced placebo effects in 13% to 15%, 15% to 20%, and 18% to 30% of the patients respectively. Similarly, a nocebo effect was seen in 5% to 8% of the patients in the sodium chloride group, 8% of the patients in the midazolam group, and 3% to 8% of the patients in the fentanyl group. It is concluded that positive and negative effects may be seen either with placebo or active agents in 13% to 30% of the patients.

Over 500,000 percutaneous disc decompression procedures have been performed in the past 20 years. Various percutaneous techniques include chemonucleolysis, percutaneous lumbar discectomy, and laser discectomy which have reported success rates in the 70% to 75% range. This retrospective evaluation of 49 patients who underwent nucleoplasty procedures for treatment of herniated discs, evaluates the effectiveness of nucleoplasty in the reduction of pain, improvement of functional activity, and reduction of pain medication. ⋯ Nucleoplasty should be used in those patients who fail conservative medical management including medication, physical therapy, behavioral management, psychotherapy, and who are unwilling to undergo a more invasive technique such as spinal surgery.

In the United States, physicians are faced with two opposing dilemmas in the treatment of pain - the potential for drug abuse and diversion, and the possible undertreatment of pain. While controlled prescription drugs such as narcotic analgesics, anxiolytics, antidepressants, stimulants, and sedative-hypnotics, play a legitimate role in managing chronic pain and other conditions, the illicit use of prescribed medicines is increasing at epidemic proportions. Diversion and abuse of prescription drugs is costly in terms of addiction, overdose, death, and related criminal activities, but chronic pain carries significant economic, social, and health impact as well. ⋯ President George W. Bush signed NASPER on August 11, 2005, and it became Public Law 109-60. Implementation of NASPER will improve patient care and reduce abuse and diversion of prescription controlled substances.
