A prospective single-arm clinical study. ⋯ The 29% change in intended surgical plans suggested that SPSI was considered by spine surgeons as an adjunct metric in deciding whether to perform decompression only or to add instrumented fusion. This change exceeded the a priori defined 15% considered necessary to show the potential clinical utility of SPSI.

Prospective cohort study. ⋯ The 6MWD of CSM patients was significantly lower than that of the healthy population and correlated well with commonly used clinical scales. The 6MWD can potentially assist in the assessment of functional status in patients with CSM.
-
Retrospective study. ⋯ We found higher percentages of overall survival with R0 tumor resection and lower histologic grade, whereas development of metastatic disease was closely associated with local recurrence and poor survival. Despite the improvements in treatment paradigms, it is sobering that our findings largely mirror those of previous work considering patients treated between 1984 and 2006.
