Multicenter Study
Temporal Shape Changes of Pedicle screw-rod Constructs After Lumbar Interbody Fusion.
Retrospective multicenter study. ⋯ The temporal shape changes of screw-rod constructs following short-segment lumbar interbody fusion progressed up to 6 months after surgery but not significantly thereafter.
-
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.

Systematic review and meta-analysis. ⋯ In summary, our meta-analysis suggests that LSSE can potentially improve disability, especially when used as a single treatment. LSSE appears more beneficial in reducing disability than alleviating pain. Future research on different patient groups is needed to understand comprehensively LSSE's effects on other musculoskeletal disorders.

Systematic review. ⋯ Level IV.
-
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.
