Comparative Study
A prospective comparison of surgical approach for anterior L4-L5 fusion: laparoscopic versus mini anterior lumbar interbody fusion.
A prospective comparison of 50 consecutive patients who underwent L4-L5 anterior lumbar interbody fusion (ALIF). ⋯ There does not appear to be a significant advantage at the L4-L5 level of the transperitoneal laparoscopic surgical approach when compared with an open mini-ALIF retroperitoneal technique.

Prospective case series. ⋯ A cohort of patients with chronic unremitting low back pain of discogenic origin whose symptoms had failed to improve with aggressive nonoperative care demonstrated a statistically significant and clinically meaningful improvement on the SF-36 and the VAS scores at a minimum follow-up of 1 year after IDET. The positive results should be validated with placebo-controlled randomized trials and studies that compare IDET with alternative treatments.-

In vitro study to determine occupational radiation exposure during lumbar fluoroscopy. ⋯ Fluoroscopically assisted thoracolumbar pedicle screw placement exposes the spine surgeon to significantly greater radiation levels than other, nonspinal musculoskeletal procedures that involve the use of a fluoroscope. In fact, dose rates are up to 10-12 times greater. Spine surgeons performing fluoroscopically assisted thoracolumbar procedures should monitor their annual radiation exposure. Measures to reduce radiation exposure and surgeon awareness of high-exposure body and hand positions are certainly called for.

Prospective design in which 102 patients were evaluated with a battery of psychological assessment tests 1-2 weeks before surgery, and outcome was assessed 6 months and 1 year after surgery. ⋯ These results indicate that screening for presurgical distress is likely to identify those patients at risk for poor outcome. Studies to evaluate whether presurgical psychological treatment improves outcome are warranted.
