Radiofrequency (RF) ablation is a method that has been gaining popularity over the past few years among spinal surgeons. It has a role when dealing with pain of spinal origin, either mechanical or neuropathic, after conservative treatment has failed. In the present study, 122 patients with a minimal follow up of 1 year were examined at our institution after having undergone RF heat lesion of the medial branch for mechanical spinal pain (low back pain, thoracic pain or cervical pain). ⋯ In the case of the 22 patients who were followed for 18 months, all showed significant pain relief. Minor complications occurred in 27 patients (22%), who had transient discomfort and burning pain. We concluded that RF is a safe and partially effective procedure for mechanical back pain.

Comparative Study
Comparison of instrumented anterior interbody fusion with instrumented circumferential lumbar fusion.
Posterior lumbar interbody fusion (PLIF) restores disc height, the load bearing ability of anterior ligaments and muscles, root canal dimensions, and spinal balance. It immobilizes the painful degenerate spinal segment and decompresses the nerve roots. Anterior lumbar interbody fusion (ALIF) does the same, but could have complications of graft extrusion, compression and instability contributing to pseudarthrosis in the absence of instrumentation. ⋯ There was no significant difference between the compensation rate and disability benefit rate between the two groups. There were three complications in ALIF group and four in the PLIF (circumferential) group. On the basis of these results, we conclude that it is possible to treat discogenic back pain by anterior interbody fusion with Hartshill horseshoe cage or with circumferential fusion using instrumented PLIF.

Randomized Controlled Trial Clinical Trial
The effect of perioperative corticosteroids on the outcome of microscopic lumbar disc surgery.
Eighty adult patients with lumbar disc herniation verified by magnetic resonance imaging (MRI) and clinical findings corresponding to the radiological level underwent microscopic disc removal to evaluate the outcome of perioperatively given corticosteroids in a prospective randomized double-blind study. In the treatment group the patient received 250 mg Solu-Medrol intravenously and 160 mg Depo-Medrol intramuscularly. Before closure of the wound, a free fat transplant soaked in 80 mg Depo-Medrol was placed on the dural sac. ⋯ Postoperative spondylitis occurred in one patient in the control group and no adverse corticosteroids effect was seen. Our study shows that perioperatively given corticosteroids improve the outcome of microscopic disc surgery in terms of length of hospital stay and time taken to return to full-time work. The results also indicate that corticosteroid treatment reduces pain and improves functional outcome.

One of the major challenges for general practitioners is to manage individuals with acute low back pain appropriately to reduce the risk of chronicity. A prospective study was designed to assess the actual management of acute low back pain in one primary care setting and to determine whether existing practice patterns conform to published guidelines. Twenty-four family physicians from public primary care centers of the Basque Health Service in Bizkaia, Basque Country (Spain), participated in the study. ⋯ The diagnostic process showed a low rate of appropriate use of history (27%), physical examination (32%), lumbar radiographs (31%), and referral to specialized care (33%). Although the therapeutic process showed a relatively high rate of appropriateness in earlier mobilization (77%) and educational advice (65%), only 23% of patients were taught about the benign course of back pain. The study revealed that management of acute low back pain in the primary care setting is far from being in conformance with published clinical guidelines.

There have been a large number of epidemiological studies demonstrating various primary factors that cause musculoskeletal disorders in middle-aged and older women. However, the relationship between low back pain and bone mineral density is not well documented, and no evidence for any direct relationship between the two has been found. To investigate the relationship, we conducted a cross-sectional study, on a population of 2,244 Japanese women aged 25-85 years who were participating in a regional health screening program. ⋯ Exercise and smoking were also significantly associated with low back pain. This association remained even after entering other lifestyle and reproductive factors into the final model. Accordingly, high bone mineral density would seem to be as important a public health problem as low bone mineral density and osteoporosis when considering the musculoskeletal symptoms and disabilities that appear in middle-aged women.
