Comparative StudyCorrelative analysis of lateral vertebral radiographic variables and medical outcomes study short-form health survey: a comparative study in asymptomatic volunteers versus patients with low back pain.
This prospective comparative study was designed to investigate the possible link between SF-36 functional status and lateral roentgenographic variables of the standing lumbar spine in patients with low back pain (LBP) versus asymptomatic volunteers. To the authors' knowledge, no previous studies have correlated SF-36 scores and sagittal roentgenographic variables in patients with LBP versus asymptomatic individuals. A total of 100 male volunteers, used as controls, and an equal number of age-, height-, and weight-comparable patients of the same ethnicity with chronic LBP were compared on the basis of roentgenographic and SF-36 data. ⋯ For the patients with LBP this study showed that General health, Physical Functioning, Role-Emotional, Social Functioning, and Bodily Pain were significantly correlated with age, height, L1-L2 inclination, distal lordosis, L2-L5 index, and L4-L5 and L5-S1 disc index. This comparative study showed that the functional status of hard-working patients with chronic LBP is associated with degenerative changes on the lateral radiographs of the lumbosacral spine. Spine surgeons should take into consideration the results of this study in reconstruction of painful degenerative lumbosacral spine.

This prospective, non-randomized clinical trial was designed to determine the clinical outcome of patients who underwent Intradiscal Electrotherapy (IDET) for the treatment of chronic discogenic low back pain. Twenty-seven consecutive patients undergoing IDET were prospectively evaluated. All patients, as determined by provocative discography and/or MRI, had discogenic disease with chronic low back pain and were non-responsive to conservative treatment for at least 6 months. ⋯ This did not translate into a significant improvement in the SF-36 survey scores. The risks are negligible, and recovery time is minimal. The procedure may be useful in selected patients who would otherwise undergo an interbody fusion procedure.

The role of zygapophysial (facet) joints in chronic thoracic pain has received very little attention with only a few publications discussing these joints as sources of pain. In contrast, facet joints have been implicated as responsible for chronic pain in a significant proportion of patients with chronic neck and low back pain. However, thoracic spinal pain, though less common, has been reported to be as disabling as neck and low back pain. ⋯ Results showed that 46 patients underwent single blocks with lidocaine and 36 of these patients, or 78%, were positive for facet joint pain, reporting a definite response. Confirmatory blocks with bupivacaine were performed in all patients who were lidocaine-positive, with 61%, or 48% of the total sample of the lidocaine-positive group, reporting a definite response with improvement in their pain. Thus, comparative local anesthetic blocks showed the prevalence of facet joint pain to be 48%, with single blocks carrying a false-positive rate of 58%.

Randomized Controlled Trial Comparative Study Clinical Trial
Does acupuncture improve the orthopedic management of chronic low back pain--a randomized, blinded, controlled trial with 3 months follow up.
This prospective, randomised controlled trial, with three parallel groups, patient and observer blinded for verum and sham acupuncture and a follow up of 3 months raises the question: "Does a combination of acupuncture and conservative orthopedic treatment improve conservative orthopedic treatment in chronic low back pain (LBP). 186 in-patients of a LBP rehabilitation center with a history of LBP >or=6 weeks, VAS >or=50mm, and no pending compensation claims, were selected; for the three random group 4 weeks of treatment was applied. 174 patients met the protocol criteria and reported after treatment, 124 reported after 3 months follow up. Patients were assorted 4 strata: chronic LBP,

To review evidence on the diagnostic accuracy of clinical information and imaging for patients with low back pain in primary care settings. ⋯ The data suggest a diagnostic strategy similar to the 1994 Agency for Health Care Policy and Research guidelines. For adults younger than 50 years of age with no signs or symptoms of systemic disease, symptomatic therapy without imaging is appropriate. For patients 50 years of age and older or those whose findings suggest systemic disease, plain radiography and simple laboratory tests can almost completely rule out underlying systemic diseases. Advanced imaging should be reserved for patients who are considering surgery or those in whom systemic disease is strongly suspected.
