Randomized Controlled Trial
The perioperative cost of Infuse bone graft in posterolateral lumbar spine fusion.
There is mounting evidence supporting the efficacy of bone morphogenetic protein (BMP) for both anterior interbody and posterolateral lumbar fusion. However, the relative cost of BMP remains an important concern for physicians, hospitals, and payers. ⋯ The hospital carries the cost burden associated with the utilization of rhBMP-2/ACS. In contrast, the payer in a Diagnosis-Related Group (DRG) model achieves a net savings, based primarily on the decreased payment for inpatient rehabilitation, but also on decreased hospital reimbursement, physician costs, and other outpatient services.

Randomized Controlled Trial Comparative Study
Lumbar microdiscectomy under epidural anesthesia: a comparison study.
Lumbar microdiscectomy is most commonly performed under general anesthesia, which can be associated with several perioperative morbidities including nausea, vomiting, atelectasis, pulmonary aspiration, and prolonged post-anesthesia recovery. It is possible that fewer complications may occur if the procedure is performed under epidural anesthesia. ⋯ Epidural anesthesia as an alternative to general anesthesia has shown less postoperative nausea and vomiting in lumbar microdiscectomy. Nevertheless, given the small number of patients, this study should be considered as preliminary, showing small differences in minor potential complications.

Validity of the new Backache Index (BAI) in patients with low back pain.
The Backache Index (BAI) is applied to patients with low back pain (LBP) in order to help therapists, doctors, and surgeons perform physical examinations easily. It is carried out within a short space of time (<2 min) without using inclinometric instruments. ⋯ The BAI appears to be a reliable and valid assessment of overall restricted spinal movements in case of LBP and discriminates between successful and unsuccessful treatment outcome.

Randomized Controlled Trial Comparative Study
Comparison of usual surgical advice versus a nonaggravating six-month gym-based exercise rehabilitation program post-lumbar discectomy: results at one-year follow-up.
Discectomy is the surgery of choice for the lumbosacral radicular syndrome. Previous studies on the postsurgical management of these cases compare one exercise regime to another. This study compares an exercise-based group with a control group involving no formal exercise or rehabilitation. ⋯ There was no statistical advantage gained by the group that performed the 6-month supervised nonaggravating exercise program at 1-year follow-up. They did, however, have fewer days off work.

Randomized Controlled Trial
Knowledge transfer in family physicians managing patients with acute low back pain: a prospective randomized control trial.
The process through which new scientific developments are incorporated into clinical practice is referred to as "knowledge transfer" and is currently the subject of great interest in many areas of clinical medicine. Family physicians managing patients with acute low back pain have been shown to have a poor overall rate of concordance with clinical practice guideline-recommended treatments. New methods need to be developed to help physicians bridge the guideline implementation gap. ⋯ A knowledge transfer method that involved patient-specific, physician-to-physician communication to family physicians or their patients at three stages of the patient's clinical course was largely unsuccessful in improving concordance with guideline treatment recommendations.
