Modern Concepts in Sagittal Curve Measurement: Comparison of Spline-based and Fixed Landmark Measurements in a Cohort of 1520 Healthy Subjects.
Retrospective multicenter study. ⋯ Our results suggest that the use of TK T1T12 and LL L1S1 is acceptable to assess spinal sagittal curvatures. However, TK T5T12 is not accurate for the thoracic curve and should be used with caution. LL L1S1 can be used to accurately assess the lumbar curve, except in Roussouly type 1.

Retrospective cohort. ⋯ After 1:1 exact matching, the results of this study suggest that ZP (stand-alone) implants have similar outcomes compared with grafts with plating systems, with no observed differences in all-cause surgical or medical complications profile.
-
Retrospective analysis of prospectively enrolled patients. ⋯ This study demonstrates that FI of the erector spinae and multifidus is significantly associated with less likelihood of clinically relevant ODI improvement after decompression and fusion. Further research is needed to assess the effect of interventions.

Retrospective case series. ⋯ The effects of posterior decompression surgery alone can still be observed at least 2 years postoperatively for patients with LSS and concomitant sagittal MA. Patients with sagittal MA may experience lower HRQOL than those without this type of MA.
