Randomized Controlled Trial Comparative Study
Greater peripheral blood flow but less bleeding with propofol versus sevoflurane during spine surgery: a possible physiologic model?
Prospective, randomized, single blind. ⋯ Despite the greater blood flow when it is used, propofol causes less bleeding than sevoflurane during spine surgery and could be more indicated to produce hypotension during anesthesia. Moreover, it is possible to explain our findings hypothesizing a selective vasodilation of propofol (postcapillary, venous vasodilation), different from that of sevoflurane (precapillary, arteriolar vasodilation).

Randomized Controlled Trial Comparative Study
A randomized placebo-controlled trial of single-dose IM corticosteroid for radicular low back pain.
A randomized, double-blind, placebo-controlled trial of patients with radicular low back pain who present to an emergency department (ED) within 1 week of pain onset. ⋯ This study was a negative study, though there was a suggestion of benefit of methylprednisolone acetate in a population of young adults with acute radicular low back pain. Further work with a larger sample of patients is needed.

Case report; Review of Literature. ⋯ Retroperitoneal lymphocele is a rare complication after anterior lumbar interbody fusion. The different diagnosis should include infectious abscess, ureteral injury with urinoma, pancreatic injury with pseudocyst formation, and spinal fluid leak with pseudomeningocele. Diagnosis can be guided by serum and cyst fluid analysis. Although treatment options exist, surgical treatment may provide the most reliable results.

Comparative Study Clinical Trial
Minimum four-year follow-up of spinal stenosis with degenerative spondylolisthesis treated with decompression and dynamic stabilization.
Prospective clinical study. ⋯ In elderly patients with spinal stenosis and degenerative spondylolisthesis, decompression and dynamic stabilization lead to excellent clinical and radiologic results. It maintains enough stability to prevent progression of spondylolisthesis. Because no bone grafting is necessary, donor site morbidity, which is one of the main drawbacks of fusion is eliminated. However, the degenerative disease still is progressive and degeneration at adjacent motion segments remains a problem.
