Fixing of the lumbar vertebral column aided by simple radiological techniques facilitates the process and avoids complications. This technique has arisen as a result of the conclusion of the PhD thesis by Dr. Matías Alfonso, specialist in the Department of Orthopaedic and Bone Surgery at the University Hospital of Navarre, and has been based on research carried out on a pedicular screw method based on intraoperatorial anatomical references. The study has been applied to 44 patients attending the University Hospital.
The insertion of pedicular screws into the lumbar vertebral column is suitable for the treatment of fractures, problems of instability due to degenerative illness, tumours, etc. It involves a routine technique in orthopaedics and bone surgery. Nevertheless, lesion of the nerve roots can occur as a complication, a risk that can affect up to 3% of patients.
The University Hospital has evaluated a method to guarantee the pedicular screw system in a reliable way, avoiding the neurological complications. This system groups together a series of radiological projections by means of which we can see to the borders of the vertebrae, thus enabling the path of the screws to be ascertained with precision.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
