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.

Comparative Study
Disability in subacute whiplash patients: usefulness of the neck disability index.
Cross-sectional study. ⋯ The NDI showed excellent psychometric properties in a sample of subacute whiplash patients. Additional research is needed to replicate the NDIs factor structure.

Comparative Study
Biomechanical response of a lumbar intervertebral disc to manual lifting activities: a poroelastic finite element model study.
Determination of damage to a lumbar disc caused by lifting using a poroelastic finite element model study. ⋯ Asymmetric lifting involving lateral bending of the trunk produced large motions that might cause localized disc tissue injury. Stresses larger than the failure strength of the corresponding disc tissues were experienced during asymmetric lifting. Lifting that involves lateral bending of the trunk was the most hazardous type of loading with regard to damage to the disc.

Comparative Study
Baclofen pump implantation and spinal fusion in children: techniques and complications.
Retrospective clinical and radiographic review of complications related to intrathecal baclofen therapy (ITB) and posterior spine fusion (PSF) in patients with cerebral palsy. ⋯ The rate of ITB therapy complications is not increased despite PSF in any order of the procedures. There are technical details in each situation that require attention. With understanding of the appropriate techniques of catheter management, ITB pumps can be implanted and managed without an increased complication rate before, during or after spinal fusion surgery.

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.
