Retrospective analysis of prospective multicenter adult spinal deformity (ASD) database. ⋯ In Qui type A patients undergoing cMIS with LLIF for ASD, 27.9% develop coronal malalignment, which was associated with worse SF-36 PCS and SRS-22r function/activity. Despite radiographic malalignment, malalignment was not associated with higher 2-year complication rates including reoperations.

Retrospective cohort study. ⋯ RS patients are shown to have better outcomes to CP patients in terms of surgical, perioperative, and radiographic variables. Ambulatory status was identified as an independent risk factor for complications.
-
Retrospective analysis of prospectively collected data. ⋯ In this study of complex ASD patients, patients with worse spinal deformity were more likely to have concomitant knee OA. Knee OA was shown to be a predictor of knee flexion and ankle dorsiflexion angles, but was not associated with worse PROMs in this study population. Patients with knee arthroplasty, however, had comparable spinal alignment and PROMs relative to those with mild OA.
-
Retrospective observational study. ⋯ Most scoring systems exhibited low discriminative power, with only the SORG nomogram, OSRI, and modified Tokuhashi scores demonstrating moderate power for predicting long-term survival. In the most recent period, the OSRI demonstrated the highest predictive accuracy for both 1-year and 2-year survival.

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.
