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.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
