Randomized Controlled Trial Comparative Study
A prospective randomized study of unilateral versus bilateral instrumented posterolateral lumbar fusion in degenerative spondylolisthesis.
Prospective randomized study on 82 patients with degenerative lumbar spondylolisthesis, having undergone posterolateral fusion with bilateral or unilateral instrumentation. ⋯ Unilateral instrumentation used for the treatment of degenerative lumbar spondylolisthesis is as effective as bilateral instrumentation when performed in addition to 1- or 2-level posterolateral fusion. The cost of this method is lower, saves time, and reduces possible risk inserting screws in only one side.

Randomized Controlled Trial
The use of curare during anesthesia to prevent iatrogenic muscle damage caused by lumbar spinal surgery through a posterior approach.
Prospective randomized study of patients undergoing lumbar arthrodesis. ⋯ The use of curare during anesthesia did not limit the muscle damage caused by surgery.

This was a retrospective cohort study using a previously matched convenience sample of 34 patients. ⋯ There was no statistically significant difference comparing the 2 groups, although a trend was observed toward better correction of the main thoracic curve in the all-screw construct group. The all-screw group demonstrated a significant decrease in kyphosis, which was not seen in the hybrid group. Hybrid constructs were comparable to all-screw constructs in the correction of coronal plane deformity and sagittal balance.

A retrospective study examining the clinical features, management, and treatment outcome of patients with spinal tuberculosis (TB). ⋯ Our results showed that a younger age and radical surgery in conjunction with anti-TB chemotherapy were significant favorable prognostic factors.

A cross-sectional observational study to determine the response distribution, internal consistency, and construct, concurrent, and discriminative validities of The Scoliosis Research Society-22 (SRS-22) Patient Questionnaire translated into Japanese as compared with the other language versions. ⋯ The Japanese SRS-22 is valid and may be useful for clinical evaluation of Japanese scoliosis patients, though the self-image subscale may need further assessment.
