CT with multiplanar reconstruction provides a clear multi-dimensional view of tibial triplane fractures of the ankle--a view that alters what is found in many medical textbooks and changes the way physicians understand these complex fractures, a new study shows.
The study included 51 young people, ranging in age from 10 to 17 years old. Triplane fractures, (fracture lines occur in three planes of the ankle) account for about 6%-10% of ankle fractures in young people, says Stephen D. Brown, MD, instructor in radiology at Harvard Medical School in Boston. They are generally sports-related injuries, he added.
All 51 cases showed bone separation along the front part of the growth plate of the tibia. There were 33 "classic" two-fragment fractures as seen in medical textbooks, but the "classic" three fragment fracture (which involves a separation at Kumps bump) "was not seen in this series," said Dr. Brown, lead author of the study. Three fragment fractures were seen, but they involved different fracture patterns than what has been previously described as most common, said Dr. Brown. In fact, the study found that fully half of the triplane fracture patterns described in the literature – some of which have been described as quite common - likely occur only very rarely or never at all. This is explained by the characteristic pattern of closure of the growth plate. In addition, "the medial malleolar variety of triplane fracture previously considered rare, was very common," he said. "In one-fourth of the patients in our cohort, fractures involved the medial malleolus, but spared the plafond," he said.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
