The study consisted of ten professional soccer players, between the ages of 22-30, with no previous posterior ankle pain who underwent MRI and sonographically guided injection for clinical posterior impingement. According to the study, despite rehabilitation with resolution of anterior and lateral symptoms after an initial inversion injury, all players developed posterior pain that was resistant to conservative therapy 3-4 weeks after the precipitating injury. The pain limited the athletes' ability to sprint and strike the soccer ball and prevented them from returning to competition.
"In our practice, we see many professional athletes with this condition and we found that the majority of them were showing excellent response to this treatment," said Philip Robinson, MD, and lead author of the study. "We decided to analyze the imaging features and injection results more rigorously for publication."
All players underwent MRI of the ankle after clinical examination by a foot and ankle surgeon. Sonographically guided injection was then performed into the posterior capsule abnormality. Posterolateal capsule thickening and synovitis involving an intact posterior talofibular ligament (ligament located in the back of the foot) were present in all ten patients.
According to the study, all players tolerated the injection procedure with no immediate or delayed complications. All patients noted a marked decrease in symptoms and stiffness immediately after the injection of bupivacaine (anesthetic).
"For patients, the results of this study mean that they should have a faster recovery time and may not require arthroscopy. It also demonstrates that ankle impingement syndromes which appear predominately soft tissue based can respond to image guided injection treatment," said Dr. Robinson.

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...
