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.

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.

Comparative Study
A relook into the association of the estrogen receptor [alpha] gene (PvuII, XbaI) and adolescent idiopathic scoliosis: a study of 540 Chinese cases.
A genetic association study of estrogen receptor-[alpha] gene (ESR1) with adolescent idiopathic scoliosis (AIS) in Chinese. ⋯ The previously reported association with curve severity could not be replicated in our large series of Chinese AIS patients. The current study also did not show any association of the 2 SNPs with increased risk of having AIS.

Comparative Study
Anterior exposure of the spine for removal of lumbar interbody devices and implants.
A retrospective review of a consecutive series of 14 patients operated on between March 1998 and April 2005. ⋯ Anterior removal of lumbar interbody devices placed anteriorly or posteriorly has a high incidence of complication. Average blood loss and hospital stay are increased with revision anterior surgery. The vascular complication rate is 2-fold higher at L4-L5 level compared to L5-S1.

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.
