Fatigue Performance of Cortical Bone Trajectory Screw Compared to Standard Trajectory Pedicle Screw.
Cadaveric biomechanical study. ⋯ The standard pedicle screw had a better fatigue performance compared with the CBT screw in vertebra with compromised bone quality. The proper insertion of the CBT screw might be prevented by the laminar anatomy depending on the screw head design. The CBT screw damaged the bone along its shaft by rotating around a fulcrum, located at either the pars, pedicle isthmus, or the junction of the pedicle and superior endplate, contingent upon the strength of the bone.

Retrospective cohort study. ⋯ Owing to pain limiting mobilization, a quarter of neurologically intact patients with thoracolumbar burst fractures and a TLICS score of 2 failed nonsurgical management. The greater the kyphosis, stenosis, and fragmentation of the fracture, the more likely patients required surgery. In addition to the TLICS classification, other radiographic and clinical parameters should be included in selecting appropriate treatment strategy. The cost savings with nonoperative treatment of intact burst fractures, when appropriate, are significant.
