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.
-
Retrospective. ⋯ Preoperative pain relief expectations were not associated with functional outcomes or satisfaction following 1-2 level primary ACDF or CDR at 12-month follow-up. Patients' dissatisfaction with their preoperative spinal condition was significantly associated with greater 12-month NDI improvement. Assessing preoperative satisfaction may help identify those most likely to benefit from surgery.
-
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.
