Retrospective clinical cohort study. ⋯ Translaminar screw fixation is a straightforward and effective technique for short-segment fusion in the lumbar spine. For patients with a strict indication for spondylodesis, intact posterior elements (lamina and facets) and a low preoperative disc height, translaminar screw fixation represents a successful fixation technique in the lumbar spine with good long-term results.

A biomechanical study with human cadaveric osteopenic lumbar vertebrae evaluating a novel method for cement augmentation of pedicle screw fixation. ⋯ This novel cement-delivery screw and injection technique provides a significant increase in resistance to pedicle screw motion, allowing placement of a standard screw that can be removed in revision surgery.

Randomized Controlled Trial
Anterior-only stabilization using plating with bone structural autograft versus titanium mesh cages for two- or three-column thoracolumbar burst fractures: a prospective randomized study.
A randomized, controlled follow-up study to review patients with acute thoracolumbar burst fractures treated by anterior instrumentation and reconstruction. ⋯ Anterior-only instrumentation and reconstruction with structural autograft or titanium mesh cages is sufficient for surgical treatment of thoracolumbar burst fractures with a load-sharing score of > or = 7 and even with 3-column injuries.

Randomized Controlled Trial
Efficacy of steroid and nonsteroid caudal epidural injections for low back pain and sciatica: a prospective, randomized, double-blind clinical trial.
Prospective, double-blind, randomized, case-control study. ⋯ CEI containing local anesthetic and steroids or WFI seems to be effective when treating patients with LBP and sciatica. CEI containing steroid preparations demonstrated better and faster efficacy.

A retrospective analysis of prospectively collected data of 102 consecutive adult patients who underwent intraoperative neurophysiological monitoring (IOM) during spinal deformity corrective surgery. ⋯ Multimodality IOM of spinal cord sensory and motor function during surgical correction of adult spinal deformity is feasible and provides useful neurophysiological data with an overall sensitivity of 100% and a specificity of 84.3% (67% and 98%, respectively in patients undergoing major deformity correction).
