Sectioning of the ATiFL results in mechanical instability of the syndesmosis. Of all trauma mechanisms, external rotation of the ankle resulted in the largest and most consistent displacements of the fibula relative to the tibia found at the syndesmosis. Based on our findings and the current literature, we recommend that patients with isolated PTiFL or AD injuries should be treated functionally when no other injuries are present. Patients with acute complete ATiFL ruptures, or combined ATiFL and AD ruptures should be treated with immobilization in a plaster. Patients with combined ruptures of the ATiFL, AD and PTiFL need to be treated with a syndesmotic screw.
Glucosamine sulfate was no better than placebo in reducing symptoms and progression of hip osteoarthritis. International Standard Randomised Controlled Trial Number: ISRCTN54513166.
Downtown pedestrian shopping was observed with the purpose of determining whether shoppers attempted to minimize walking distance, and, if so, whether, as has been suggested in previous research, they did that by successively choosing the closest locations. In downtown of an average-sized Swedish city (about 80000 residents), 150 shoppers were interviewed in a parking lot when they were coming back from shopping rounds. 69% of the shoppers visited more than one location, and 51% visited more than two locations. Of those who visited more than two different locations, 35 (69%) attempted to minimize walking distance. This was most frequently done by first choosing the location farthest away, then minimizing distance successively back to the parking lot. In this way shoppers probably attempted to minimize both the walking distance and the effort to carry goods. Some shoppers managed to choose routes which were shorter than if they had minimized distance successively. This finding was consistent with the results of laboratory studies demonstrating the role of maplike mental representations for distance-minimizing choices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
