Comparative Study
In vivo erector spinae muscle blood volume and oxygenation measures during repetitive incremental lifting and lowering in chronic low back pain participants.
A case control study. ⋯ The results indicated that the chronic LBP participants demonstrated a reduced cardiorespiratory and erector spinae muscle response during repetitive incremental lifting and lowering to volitional fatigue as compared to the healthy controls.

Retrospective review. ⋯ DTs are common during degenerative lumbar spine surgery. Revision surgery is twice as likely as primary surgery to result in this complication. Our postoperative early mobilization protocol appears to be an effective and safe management strategy for treating this complication (98.2% success rate). Very few patients (6 of 338, or 1.8%) needed a reoperation.

Randomized Controlled Trial Comparative Study
Optimal end-tidal concentration of sevoflurane to test an ankle clonus in children.
A prospective randomized study on the end-tidal concentrations of sevoflurane at which ankle clonus existed. ⋯ The ankle clonus should be tested at 0.45% volume of end-tidal sevoflurane concentration in children undergoing scoliosis surgery during emergence from the general anesthesia.

A cross-sectional study to evaluate the long-term result of posterolateral (PLF), anterior (AF), and circumferential fusion (CF) for isthmic spondylolisthesis. ⋯ The clinical outcome was best in the CF group as measured by ODI. Degenerative changes were most commonly found at the level of the slip and above the fusion level. The prevalence of disc prolapses was low. Spinal fusion for isthmic spondylolysis is not associated with central canal stenosis above the fusion. Radiologic nerve root stenosis was common but asymptomatic. Mild muscle atrophy was common.

Randomized Controlled Trial Multicenter Study Comparative Study
Effect of high-dose intravenous dexamethasone on postlumbar discectomy pain.
A prospective, randomized triple-blind clinical trial. ⋯ Intraoperative IV injection of 40 mg dexamethasone could effectively reduce postoperative radicular leg pain and narcotics usage in patients with single-level herniated lumbar disc.
