Write a letter to editors concerning: Comparison of cervical, thoracic, and lumbar vertebral bone quality scores for increased utility of bone mineral density screening by Razzouk et al. (Eur Spine J https://doi.org/10.1007/s00586-022-07484-5 , 2022). We try to compare the targeted article with a similar article to talk about cervical vertebral bone quality (VBQ). ⋯ We advised the targeted article's authors to try their research again in another way of calculation of cervical VBQ like the contrast article.

Combined flexion and compression negatively impact the mechanical integrity of the annulus fibrosus.
To observe the effect of static flexion, in combination with compression, on the intralamellar and interlamellar matrix properties of the annulus fibrosus. ⋯ The current findings suggest that the mechanical properties of the interlamellar and intralamellar matrices are sensitive to flexion, creating an environment that promotes an increased potential for damage to occur.

Conditional survival (CS) provides a dynamic prediction of patient survival by incorporating the time an individual has already survived given their disease specific characteristics. The objective of the current study was to estimate CS among patients after surgery for spinal cord compression or spinal instability, as well as stratify CS according to relevant patient- and disease-related characteristics. ⋯ Level IV (retrospective cohort study).

To compare the diagnostic value of curved planar reformation of MRI (MRI-CPR) and 2D MRI in determining the responsible nerve in patients with adult lumbar degenerative scoliosis (ALDS). ⋯ The clinical diagnostic value of MRI-CPR was better than 2D MRI in the determination of the responsible nerve root. Moreover, MRI-CPR sequence images can clearly show the route of lumbosacral nerve roots and their relationship with adjacent tissues. Therefore, MRI-CPR can be an important complement to conventional 2D MRI in the diagnosis of responsible nerve roots in patients with ALDS.

Astronauts returning from long ISS missions have demonstrated an increased incidence of lumbar disc herniation accompanied by biomechanical and morphological changes associated with spine elongation. This research describes a ground-based study of the effects of an axial compression countermeasure Mk VI SkinSuit designed to reload the spine and reduce these changes before return to terrestrial gravity. ⋯ The MkVI SkinSuit restores lumbar mobility and lordosis following 4 h of wearing during hyper buoyancy flotation in a healthy control population and may be an effective countermeasure for post space flight lumbar disc herniation.
