Cortical Bone Trajectory for Thoracic Pedicle Screws: A Technical Note.
A morphometric measurement of new thoracic pedicle screw trajectory using computed tomography (CT) and a biomechanical study on cadaveric thoracic vertebrae using insertional torque. ⋯ The detailed morphometric measurement and favorable screw fixation stability of thoracic CBT are reported. The insertional torque using thoracic CBT technique was 53.8% higher than that of the traditional technique.

Height restoration and preservation in osteoporotic vertebral compression fractures: a biomechanical analysis of standard balloon kyphoplasty versus radiofrequency kyphoplasty in a cadaveric model.
Biomechanical cadaver study. ⋯ On the basis of our results, the unipedicular RFK in osteoporotic compression fractures might represent a promising alternative for the clinical setting.

Comparative StudyEffective cervical decompression by the posterior cervical foraminotomy without discectomy.
A retrospective review. ⋯ Despite the surgical and anatomic limitations, PCF with or without discectomy is an effective treatment for cervical disk herniation.

Risk factors for L5-S1 disk height reduction after lumbar posterolateral floating fusion surgery.
This is a retrospective study. ⋯ In posterolateral floating fusion surgery, there was a higher risk of L5-S1 disk height reduction and consequent foraminal stenosis in patients with multiple-level fusion. Surgical methods and fusion levels should be chosen after considering their association with L5-S1 disk height reduction.

Review Meta Analysis Comparative StudyLumbar fusion versus nonoperative management for treatment of discogenic low back pain: a systematic review and meta-analysis of randomized controlled trials.
Systematic review and meta-analysis of randomized controlled trials (RCTs). ⋯ Despite the significant improvement in ODI in the lumbar fusion groups in 3 studies, pooled data revealed no significant difference when compared with the nonoperative group. Although there was an overall improvement of 7.39 points in the ODI in favor of lumbar fusion, it is unclear that this change in ODI would lead to a clinically significant difference. Prospective randomized trials comparing a specific surgical technique versus a structured physical therapy program may improve evidence quality. Until then, either operative intervention by lumbar fusion or nonoperative management and physical therapy remain 2 acceptable treatment methods for intractable low back pain.
