Case Reports
Traumatic expulsion of T4 vertebral body into the spinal canal treated by vertebrectomy and spine shortening.
A case report. ⋯ Total vertebrectomy and spinal shortening are safe and replicable procedures applicable in few patients with paraplegia. A surgical procedure after 3 weeks makes a complete reduction and a perfect sagittal alignment of the spine difficult to be obtained.

Retrospective cohort study of 183 patients who underwent elective anterior cervical discectomy and fusion (ACDF) at a single institution during a 2-year period. ⋯ 3.

Multicenter Study
Association of postoperative shoulder balance with adding-on in Lenke Type II adolescent idiopathic scoliosis.
A retrospective, multicenter study. ⋯ The postoperative shoulder balance and postoperative distal adding-on were weakly but significantly associated with each other, and both shoulder imbalance and adding-on need to be prevented in Lenke type 2 curves.

Retrospective review of prospective database. ⋯ Extension of long fusions to the sacrum resulted in significant and sustained improvements in Oswestry Disability Index and Scoliosis Research Society scores and alignment during 5 years PO compared with baseline. Major surgical complications occurred in 30% and reoperations were performed in 20%, but outcome scores after treatment were similar to those without complications or reoperations.

Retrospective study. ⋯ It seems that upper cervical levels are more likely to degenerate and to have more advanced degrees of degeneration than the lower cervical levels. As expected, age correlates with worsening degeneration. The proposed computed tomographic grading system for cervical facet arthrosis seemed to be reliable.
