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.

Clinical TrialIntraoperative computed tomography with an integrated navigation system in stabilization surgery for complex craniovertebral junction malformation.
This study was designed to report our preliminary experience with stabilization procedures for complex craniovertebral junction malformation (CVJM) using intraoperative computed tomography (iCT) with an integrated neuronavigation system (NNS). ⋯ iCT scanning with integrated NNS was found to be both feasible and beneficial in the stabilization procedures for complex CVJM. In this unusual patient population, the technique seemed to be of value for negotiating complex anatomy and for achieving more control over screw placement.

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.

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.
