Forty-three patients with histories of fractures, arthrodesis (joint fusion) or spinal fusions who'd undergone MDCT and conventional radiography for the evaluation of bone healing were included in this study. Mutiplanar reconstructions and radiographs were analyzed by two musculoskeletal radiologists in consensus interpretation to determine bone healing.
According to the results, no evidence of bone bridging was shown in 14 patients, 23 patients showed evidence of partial fusion, and six patients showed complete fusion. In 27 patients (63%), MDCT and digital radiography were concordant with regard to the extent of bone healing, while in 16 patients (37%) the results were not concordant. In eight patients digital radiographs underestimated the extent of bone healing, while in another eight patients they overestimated the degree of fusion. "Most cases were dealing with bonehealing after spondylodiscitis, fractures or arthrodesis," said Christian R. Krestan, MD, lead author of the study. "However no scientific data were available concerning the value of MDCT in bone healing compared to radiographs, which had been used for decades in this indication," said Krestan.
"The results of this study have a considerable impact on orthopedic patients and lead to a substantial improvement in patient care," said Krestan. "The exact diagnosis or exclusion of bone healing provides a basis for decisions like mobilization or immobilization and even repeated surgery in these patients," he said.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
