Multicenter Study Comparative Study
Results of selective thoracic versus nonselective fusion in Lenke type 3 curves.
A retrospective analysis of a prospectively collected multicenter database. ⋯ Despite preoperatively smaller lumbar curves with less apical translation and lumbar prominence, most patients with selective fusions were out of balance postoperatively and had inferior radiographical outcomes as compared with their nonselective comparison cohort with similar patient-reported outcomes. Long-term follow-up is required to determine whether the trade-off of sparing motion segments at the expense of somewhat lessened radiographical outcomes is worthwhile.

Review Case Reports
Primary myoepithelioma of the dorsal spine: a case report and review of literature.
Case report and review of the relevant literature. ⋯ Primary myoepithelioma of spine is very rare. Gross total resection with wide resection margins in the paraspinal region should be used to tackle this rare entity as the role of adjuvant therapy is doubtful. Long-term follow-up is a must.

Simulate the progression of human disc degeneration. ⋯ Poor nutritional supply has a long-term effect on disc degeneration.

Prospective cohort study. ⋯ Patients undergoing elective lumbar arthrodesis reported relatively limited functional deficit due to stiffness at 2-year follow-up. Paradoxically, patients undergoing 1-level arthrodesis actually reported significantly less limitation due to stiffness postoperatively. Although the effects of stiffness did trend toward greater impacts among patients undergoing longer fusions, 91% of patients were satisfied with trade-offs of function and pain relief in exchange for perceived increases in lumbar stiffness.
