Multicenter Study Observational Study
Prediction of outcomes for symptomatic spinal cavernous malformation surgery: a multicenter prospective clinical study.
Clinical outcome of spinal cavernous malformation (SCM) varies because of its unclear natural history, and reliable prognostic prediction model for SCM patients is limited. The aim of the present study was to investigate potential factors that predict one-year neurological status in postoperative patients with SCM. ⋯ Admission size of the lesion, morphology, symptom duration, AIS grade and the presence of subarachnoid hemorrhage were strong outcome predictors regarding prognostication of neurological outcome in postoperative patients with SCMs. A decision to surgically remove a symptomatic SCM should be justified by systematic analysis of all factors potentially affecting outcome.

Multicenter Study
Pediatric cervical spine injuries-results of the German multicenter CHILDSPINE study.
The aim of this study was to provide epidemiological data of pediatric patients suffering from cervical spinal trauma in Germany, in order to integrate these data in future decision-making processes concerning diagnosis and therapy. ⋯ The upper cervical spine was more frequently affected in young children. Older children more often suffered from subaxial pathologies. The majority of cervical spinal column injuries were treated conservatively. Nevertheless, 15% of the hospitalized children had to be treated surgically.

Adult spinal deformity (ASD) surgery carries a higher risk of perioperative systemic complications. However, evidence for the effect of planned two-staged surgery on the incidence of perioperative systemic complications is scarce. Here, we evaluated the effect of two-staged surgery on perioperative complications following ASD surgery using lateral lumbar interbody fusion (LLIF). ⋯ Our study suggested that two-staged surgery was not associated with risk for perioperative systemic complications following ASD surgery using LLIF.

Does the use of postoperative brace help preventing mechanical complications following adult deformity surgery?
There is scarce information regarding the effectiveness of postoperative braces in decreasing mechanical complications and reinterventions following adult deformity surgery. ⋯ After controlling for potential confounders, our study could not identify the protective effect of postoperative braces preventing mechanical complications and reinterventions in the first two postoperative years.

Multicenter Study
The age-specific normative values of standing whole-body sagittal alignment parameters in healthy adults: based on international multicenter data.
To investigate the age-specific normative values of whole-body sagittal alignment (WBSA) including global balance parameters in healthy adults and to clarify the correlations among parameters based on the data from three international multicenter. ⋯ While several local alignment changes with age were found, changes in global parameters related to the center of gravity were kept relatively mild by the chain of compensation mechanisms including the lower limbs. We showed the normative values for a comprehensive WBSA in standing posture from large international healthy subjects' database.
