Evaluation of the age related prevalence of persistent low back pain has been estimated to be consistently higher in the elderly compared to the younger population. Facet joints have been shown to be the cause of chronic low back pain in 15% to 45% of the patients in controlled studies. Prevalence of facet joint mediated pain has not been studied in the elderly. ⋯ Facet joints were investigated with diagnostic blocks initially using lidocaine 1% followed by bupivacaine 0.25%, usually 2 weeks apart. The prevalence of facet joint mediated pain was determined to be 30% in the adults and 52% in the elderly, which was significantly higher with a false positive rate of 26% in adults and 33% in the elderly. In conclusion, the results of this study show that facet joint mediated pain is a significant problem in all patients suffering with chronic low back pain with the prevalence of 52% in the elderly and 30% in adults.

Epidural steroid injections are the most commonly used procedures to manage chronic low back pain in interventional pain management settings. Approaches available to access the epidural space in the lumbosacral spine include the interlaminar, transforaminal, and caudal. The overall effectiveness of epidural steroid injections has been highly variable. ⋯ The study also showed cost effectiveness of this treatment, with a cost of $ 2550 for 1-year improvement of quality of life. In conclusion, caudal epidural injections with steroids or Sarapin are an effective modality of treatment in managing chronic, persistent low back pain that fails to respond to conservative modalities of treatments and is also negative for facet joint pain. The treatment is not only effective clinically but also is cost effective.

An attempt was made to determine the relative contribution of various structures to chronic low back pain, including facet joint(s), disc(s), and sacroiliac joint(s) in a prospective evaluation. Precision diagnostic blocks, including disc injections, facet joint blocks, and sacroiliac joint injections, are frequently used. ⋯ One hundred and twenty patients with a chief complaint of low back pain were evaluated with precision diagnostic injections, which included medial branch blocks, provocative discography and sacroiliac joint injections. In 40% (95% CL, 31%, 49%), of the patients, facet joint pain was diagnosed; and in 26% (95% CL, 18%, 34%) of the patients discogenic pain was diagnosed; and 2% of the patients were diagnosed with sacroiliac joint pain.

Alpha(2) agonists have been in clinical use for decades, primarily in the treatment of hypertension. In recent years, alpha(2) agonists have found wider application, particularly in the fields of anesthesia and pain management. It has been noted that these agents can enhance analgesia provided by traditional analgesics, such as opiates, and may result in opiate-sparing effects. ⋯ The clinical utility of these agents is ever expanding, as they are gaining broader use in neuraxial analgesia, and new applications are continuously under investigation. The alpha(2) agonists that are currently employed in anesthesia and pain management include clonidine, tizanidine, and dexmedetomidine. Moxonidine and radolmidine, which are not currently in clinical use in humans, may offer favorable side-effect profiles when compared with traditional alpha(2) agonists, and may thereby allow for more widespread pain management applications.

While drug therapy is one of the most commonly used modalities of treatment in managing persistent or chronic pain, controversy continues with regards to the appropriate use of controlled substances, specifically opioid analgesics, in interventional pain medicine settings. This study included 100 randomly selected patients receiving opioids in an interventional pain medicine setting. The patient's controlled substance profile was evaluated using multiple means. ⋯ There were no significant differences noted either in demographic characteristics or psychological characteristics, except for a higher prevalence of depression in the abuse group. In conclusion, there was significant abuse of opioids in an interventional pain medicine setting, with an incidence of 24%, with frequent abuse seen in almost half of these patients. Thus, it is important for interventional pain physicians to recognize this possibility and also to recognize that there is no definite physiologic, psychologic or demographic information to suggest abuse, even though depression was more prevalent in abuse patients.
