This study was designed to determine the prevalence of lumbar facet joint pain in patients suffering with or without somatization disorder. The study was performed using comparative local anesthetic blocks. One hundred consecutive patients with chronic low back pain, with or without somatization, were evaluated. ⋯ The evaluation also was extended to depression, generalized anxiety disorder and combinations with or without somatization thereof which showed no significant differences in the prevalence of facet joint pain. The results of this study demonstrated that the facet joint was a source of pain in chronic low back pain patients in 44% of the patients without somatization and 38% of the patients with somatization. This study also showed that there was no correlation between the presence or absence of facet joint pain and the presence or absence of somatization disorder or any other psychological condition or combination thereof.

Different anatomical structures and pathophysiological functions can be responsible for lumbar pain, each producing a distinctive clinical profile. Pain can arise from the intervertebral disc, either acutely as a primary disc related disorder, or as result of the degradation associated with chronic internal disc disruption. In either case, greatest pain provocation will be associated with movements and functions in the sagittal plane. ⋯ Either of these conditions will produce the greatest pain provocation during three-dimensional movements, due to maximal stress to either the synovium or joint cartilage. Finally, patients can experience different symptoms associated with irritation to the dural sleeve, dorsal root ganglion, or chemically irritated lumbar nerve root. Differential diagnosis of these conditions requires a thorough examination and provides information that can assist the clinician in selecting appropriate management strategies.

The objective of this international, multicenter, open-label trial was to assess the efficacy and safety of up to 12 months of therapy with transdermal therapeutic system (TTS) fentanyl in patients (n = 532) with chronic noncancer pain. The trial was completed by 301 (57%) of the patients. The main outcome measures were pain control assessment, global treatment satisfaction, patient preference for TTS fentanyl, and quality of life. ⋯ It was preferred by the majority of patients compared with their previous opioid medication. Overall, long-term treatment with TDF was generally well tolerated, particularly in view of the low incidence of potentially serious side effects such as drug abuse/dependence and respiratory depression. However, at present, it is important that patients receiving TDF should still be subject to careful assessment and monitoring.

Chronic low back pain and obesity are two common medical conditions. Obesity has been associated with symptoms such as adverse fat distribution and multiple secondary disorders, including low back pain. Obesity is defined as being 30% over ideal weight, which influences normal body mechanics as well as recovery from an injury. ⋯ The results showed that the prevalence rate of facet joint pain in chronic low back pain in Group I or nonobese patients was 36%, in contrast to 40% in Group II, or the obese patient group, with no significant differences among the two groups. The study also showed a false-positive rate of 39% in the total sample, or 44% in Group I nonobese patients and 33% in Group II, or obese patients. It is concluded that the prevalence of lumbar facet joint mediated pain of 40% in obese patients and 36% in patients of normal weight with a false-positive rate of 33% in obese patients and 44% in nonobese patients is similar to the results of multiple previous studies concluding that facet joint mediated pain is a common occurrence in obese patients; however, the incidence of facet joint mediated pain is similar in obese patients and nonobese patients.

Spinal endoscopy with epidural adhesiolysis is an interventional pain management technique which emerged during the 1990s. It is an invasive but important treatment modality in managing chronic low back pain that is nonresponsive to other modalities of treatment, including percutaneous spring guided adhesiolysis and transforaminal epidural injections. ⋯ Percutaneous endoscopic lysis of epidural scar tissue has been shown to be cost effective and a safe modality. This review discusses various aspects of endoscopic adhesiolysis, including clinical effectiveness, complications, rationale, and indications.
