Comparative Study
Cervical spine imaging using standard C-arm fluoroscopy: patient and surgeon exposure to ionizing radiation.
A cadaveric cervical spine specimen is imaged with a standard C-arm fluoroscope during a simulated procedure. Patient and surgeon exposure to radiation is estimated by placing dosimeters at various locations in 3-dimensional space. ⋯ Care should be taken when working on both sides of the imaged subject. Considerable radiation exposure can be encountered when working with a C-arm fluoroscope if appropriate precautions are not observed. All appropriate radiation dose-reducing measures should be strictly enforced by the supervising physician to minimize risk to the patient and the medical team.

Case Reports Comparative Study
Comparing the clinical and radiological outcomes of pedicular transvertebral screw fixation of the lumbosacral spine in spondylolisthesis versus unilateral transforaminal lumbar interbody fusion (TLIF) with posterior fixation using anterior cages.
This study retrospectively compares the clinical and radiologic outcomes of unilateral transforaminal lumbar interbody fusion (TLIF) with those of transvertebral screw fixation of the lumbosacral spine in high-grade spondylolisthesis. ⋯ No significant differences in radiologic and clinical outcome were found, in either group. Both procedures appear to be safe and effective surgically and radiographically.

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
Correlation between centrally versus peripherally transduced venous pressure in prone patients undergoing posterior spine surgery.
Prospective clinical observational study. ⋯ CVP and PVP correlate well under conditions associated with prone spine surgery. With a high level of agreement found in this study, PVP may represent an attractive alternative to CVP monitoring to assess fluid volume trends intraoperatively.
