Clinical registries are used for quality management and clinical research. Due to the importance and implications of both aims, completeness and high quality of data are of paramount importance. However, this remains uncertain, as none of these registries have implemented independent monitoring. The aim of this study was to determine the accuracy and completeness of registry data o the example of the German Spine Society (DWG) registry. ⋯ Due to the high inaccuracy, the high number of centers lacking mandatory entries at all and the number of false entries, these data alert us to advocate unannounced audits and further measures to improve the situation. Data should not be used for the time being, since wrong conclusion will be drawn. These slides can be retrieved under Electronic Supplementary Material.

Little is known about the qualitative results (postoperative upper/lower lumbar arches distribution and lumbar apex or inflection point positioning) of lumbar pedicle subtraction osteotomies (L-PSO) depending on the level of L-PSO. ⋯ The level of L-PSO influenced upper/lower lumbar arches distribution, and lumbar apex and inflection point positioning. The correct level should be chosen based on the individual assessment of each patient.

While the clinical impact of coronal and sagittal alignment in adult spinal deformity (ASD) patients (pts) is established, there is a paucity of data in terms of axial plane deformity and potential association between muscle degeneration and 3D deformity. The purpose of this study was to analyze spinopelvic muscles characteristics in association with the 3D deformity of ASD patients. ⋯ This study analyzed for the first time the relationship between 3D radiographic parameters and muscular characteristics in ASD. Sagittal malalignment is associated with increased FI and decreased muscle volumes with poor outcomes. These slides can be retrieved under Electronic Supplementary Material.

To investigate the psychometric properties of the Japanese version of the Core Outcome Measures Index-Back (COMI-Back), only recently published according to the established linguistic and cultural conversion guidelines, in patients undergoing spine surgery. ⋯ The Japanese COMI-Back was a reliable and responsive questionnaire in our Japanese patients undergoing thoracic/lumbar spine surgery. These slides can be retrieved under Electronic Supplementary Material.

Injury to the cervical spinal cord has been suggested as a mechanism that may underpin chronic whiplash-associated disorder (WAD). This study aimed to assess metabolite concentrations indicative of neuronal injury or pathology in the cervical cord in people with chronic WAD. ⋯ Findings are consistent with major metabolic changes not being present in chronic WAD.
