Radiographic analysis of PEEK cage and FRA in adult spinal deformity fused to sacrum.
Retrospective radiographic study. ⋯ Both PEEK cages and FRAs can significantly increase disk space height and achieve similar clinical outcomes in treating adult spinal deformity fused to the sacrum. The radiographic results of PEEK cages were superior to FRAs in terms of an earlier solid fusion, and greater restoration of segmental lordosis.

Function-preserving reduction and fixation of unstable Jefferson fractures using a C1 posterior limited construct.
This is a retrospective, clinical, and radiologic study of posterior reduction and fusion of the C1 arch in the treatment of unstable Jefferson fractures. ⋯ C1 posterior limited construct is a valid technique and a feasible method for treating unstable Jefferson fractures, which allows preservation of the function of the craniocervical junction, without significant morbidity.

Mortality in elderly patients following operative and nonoperative management of odontoid fractures.
Retrospective matched cohort study. ⋯ There was no significant difference between 1- and 5-year mortality in patients treated operatively or nonoperatively. Regardless of treatment Charlson score had a significant impact on mortality. Age significantly affected mortality in patients treated surgically.

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.

Comparative StudySagittal alignment after lumbar interbody fusion: comparing anterior, lateral, and transforaminal approaches.
Retrospective radiographic analysis. ⋯ After lumbar interbody fusion, improvement of lordosis was significant for both the anterior and lateral groups, but not the transforaminal group. Intergroup analysis showed the anterior group had significantly improved lordosis compared to both the other groups. The anterior and lateral groups had significantly increased disk height compared to the transforaminal group. All the 3 groups significantly reduced spondylolisthesis, with no difference between the groups.
