Multicenter Study Comparative Study
The transition from acute to subacute and chronic low back pain: a study based on determinants of quality of life and prediction of chronic disability.
Follow-up study. ⋯ LBP influences disability and quality of life more than RP. Disability is predicted by pain duration and quality of life is predicted by disability, but pain severity predicts neither one of them. Changes related to determinants of disability and quality of life, and to the prediction of chronic disability, appear 14 days after the onset of pain, supporting that cutoff point for considering a patient as being subacute.

Comparative Study
Burden of illness of chronic low back pain in Sweden: a cross-sectional, retrospective study in primary care setting.
Cross-sectional survey of patients with chronic low back pain in primary care setting. ⋯ In Sweden, the indirect costs for chronic LBP appear to be substantially higher than the direct costs for pharmaceuticals, medical visits, physiotherapy, andhospitalizations. The high indirect costs indicate that more effective treatments for chronic LBP could potentially lead to cost savings even if the therapy costs were higher.

Randomized Controlled Trial Comparative Study
Efficacy of dilute betadine solution irrigation in the prevention of postoperative infection of spinal surgery.
Prospective, single-blinded, randomized study. ⋯ Our report is the first prospective, single-blinded, randomized study to evaluate the clinical effectiveness of dilute betadine solution irrigation for prevention of wound infection following spinal surgery. We recommended this simple and inexpensive measure following spinal surgery, particularly in patients with accidental wound contamination, risk factors for wound infection, or undergoing surgery in the absence of routine ultraviolet light, laminar flow, and isolation suits.

Review Case Reports
Successful reduction for a pediatric chronic atlantoaxial rotatory fixation (Grisel syndrome) with long-term halter traction: case report.
Clinical case report of atlantoaxial rotatory fixation (AARF) in a girl presenting with torticollis and neck pain. ⋯ From this case, we suggest that long-term traction could be another treatment method for chronic AARF, especially in children.

A prospective, cohort study of 11 patients who underwent either a posterior lumbar spinal fusion with instrumentation (n = 7) or a lumbar laminotomy and discectomy alone (n = 4) and who were evaluated by dual energy radiograph absorptiometry (DEXA) to determine bone mineral density (BMD) at the adjacent three cephalad vertebral levels. ⋯ The local BMD adjacent to an instrumented lumbar fusion is increased at a mean of 10.8-years after surgery. There is a gradual decrease in BMD changes with increasing distance from the fusion level. Alterations in fusion site biomechanics and modulus mismatch between the host bone and the spinal instrumentation most likely result in chronic, localized bone remodeling with an increased BMD that decreases the greater the distance from the fusion mass.
