The aim of this study was to quantify the stabilizing effect of the passive structures in thoracic spinal motion segments by stepwise resections. These data can be used to calibrate finite element models of the thoracic spine, which are needed to explore novel surgical treatments of spinal deformities, fractures, and tumours. ⋯ The anulus fibrosus defines the motion characteristics qualitatively, while the ligaments and the presence of the nucleus pulposus restrict the mobility of a thoracic spinal motion segment solely in a quantitative manner. The posterior ligaments do not predominantly serve for primary stability but for the prevention of hyperflexion. These slides can be retrieved under Electronic Supplementary Material.

To update evidence of diagnostic potential for identification of lumbar spinal stenosis (LSS) based on demographic and patient history, clinical findings, and physical tests, and report posttest probabilities associated with test findings. ⋯ Outside of one study that was able to completely rule out LSS with no functional neurological changes none of the stand-alone findings were strong enough to rule in or rule out LSS.

To validate the reliability of Berjano and Lamartina classification system of surgical planning in cases of de novo degenerative lumbar scoliosis (DNDLS) combined with degenerative segment disease and identify factors contributing to curve progression. ⋯ Selective decompression and short-segment fusion were effective for treating type I and II cases DNDLS. The Cobb angle increased relative to preoperative sagittal spine alignment. These slides can be retrieved under Electronic Supplementary Material.

The Core Outcome Measures Index (COMI) is a short and multidimensional scale covering all domains recommended to be included in outcome measures for patients with neck pain. The purpose of the present study was to translate and cross culturally adapt the COMI into Turkish and to test its reliability and validity in patients with neck pain. ⋯ Considering the analyses, it was concluded that the Turkish version of the COMI is a valid and reliable scale for chronic neck pain patients.

For ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine, anterior decompression is the most effective method for relieving spinal cord compression. The purpose of this study was to prospectively analyze the surgical outcomes based on our strategy in the treatment of thoracic OPLL. ⋯ Anterior decompression was appropriate for patients with localized spinal cord compression by a large OPLL in the kyphotic curve, and CDF via a posterolateral approach appears to be safe and effective.
