The sagittal profile of lumbar endplates is discrepant from current simplified disc replacement and fusion device design. Endplate concavity is symmetrical in the coronal plane but shows considerable variability in the sagittal plane, which may lead to implant-endplate mismatch. ⋯ The majority of lumbar endplates are concave, while the majority of sacral endplates are flat. An oblong and an ex-centric endplate shape can be distinguished, whereby the latter is more common at the lower lumbar levels. The apex of the concavity of ex-centric discs is located in the posterior half of the endplate and the concavity of the inferior endplate is deeper than that of the superior endplate. Based on the above, the current TDR and ALIF implant design does not sufficiently match the morphology of lumbar endplates in the sagittal plane.

To evaluate and address the safety of vertebroplasty (VP) and kyphoplasty (KP) in terms of rate and type of cement leakage in the treatment of Multiple Myeloma (MM) vertebral fractures. ⋯ KP procedure in these patients is slightly less risky but we suggest doing it with a monopedicular approach. It's mandatory to use an high viscosity cement and we suggest not to use an amount of PMMA over 2 cc and a previous treatment with bone marrow transplant is related to a lower risk of cement leakage.

The objective of this study was to evaluate the reproducibility of the cervical range of motion device when measuring both active and passive range of motion in a group of individuals with sub-acute Whiplash Associated Disorders (WAD). ⋯ The CROM device has proven to be a reproducible measurement method for a symptomatic WAD population using the measurement protocol described and can be used with confidence to differentiate individuals according to a single measurement.

Cervical degenerative pathology can produce pain and disability and, in case of failure of conservative treatment surgery is indicated. ⋯ Lordotic SSA angle can be considered a protective factor against adjacent-level degeneration.

To report the results of a cohort of patients treated with this technique high lighting radiological and functional outcomes, discussing also benefits arising from a gradual reduction procedure compared with other techniques. ⋯ This is an effective and safe technique which addresses the lumbosacral kyphosis and cosmetic deformity without the neurological complications which accompany other reduction and fusion techniques for high-grade spondylolisthesis.
