Retrospective outcome measurement after circumferential reconstructive surgery with lumbar fusion in patients with chronic discogenic low back pain. ⋯ When using strict patient selection criteria that include independent determination of pain generators via pressure-controlled diskography and completion of a preoperative conditioning program for improving general health status, the number of levels in reconstructive lumbar surgery may not significantly impact overall clinical outcome.

This study retrospectively examines outcomes of unilateral transforaminal lumbar interbody fusion (TLIF) with posterior fixation using anterior carbon fiber cages and 360 degrees fusion in spondylolisthesis. ⋯ Interbody cages in spondylolisthesis are useful to increase neuroforaminal height, to facilitate reduction, and to improve the chances of achieving a successful 360 degrees fusion.

Comparative Study
Analysis of operative complications in a series of 471 anterior lumbar interbody fusion procedures.
This retrospective review compares the intraoperative and perioperative complications associated with the placement of threaded devices and nonthreaded devices used in anterior lumbar interbody fusions. ⋯ Placement of threaded devices, such as cages or bone dowels, was associated with a higher acute complication rate than was the placement of nonthreaded devices during anterior lumbar interbody fusion.

Clinical Trial
Nitrous oxide with propofol reduces somatosensory-evoked potential amplitude in children and adolescents.
A repeat measures design. ⋯ In our study, nitrous oxide use during low-dose isoflurane anesthesia supplemented with titrated propofol infusion caused a significant reduction in cortically recorded somatosensory-evoked potentials that was comparable with the 50% decrease observed in adults.

A retrospective clinical study with a follow-up of more than 4 years was conducted. ⋯ All the intervertebral bone fusion after PLIF occurred inside the cages and in the posterior intervertebral space. We suggest the complete removal of discmaterial and deep insertion of the cages to create sufficient posterior intervertebral space for bone growth. PLIF using cages impacted with laminar bone chips is a useful method when considering the time required for surgery and the morbidity of the autograft donor sites.
