The results of isolated subtalar arthrodesis using a single screw for fixation are comparable to other fixation methods. Bone graft from local sites obviates the need for iliac crest autograft in most patients.
On the basis of experience, the authors recommend meticulous attention during the surgical technique. To prevent skin irritation and stitch abscess formation leading to osteomyelitis, the FiberWire loop is best cut with a knife at least 1 cm beyond the knot, allowing the sharp end of the FiberWire to lay flat adjacent to the fibula. Painful aseptic osteolytic reaction to the TightRope necessitates removal. To prevent rediastasis, a small medial incision is recommended for endobutton positioning directly abutting the tibial cortex without soft tissue interposition. Inserting the TightRope through a fibula plate prevents lateral button pull-through and rediastasis.
Recent advances in smartphone technologies have opened the door to the development of accessible, highly portable sensing tools capable of accurate and reliable data collection in a range of environmental settings. In this article, we introduce a low-cost smartphone-based hyperspectral imaging system that can convert a standard smartphone camera into a visible wavelength hyperspectral sensor for ca. £100. To the best of our knowledge, this represents the first smartphone capable of hyperspectral data collection without the need for extensive post processing. The Hyperspectral Smartphone’s abilities are tested in a variety of environmental applications and its capabilities directly compared to the laboratory-based analogue from our previous research, as well as the wider existing literature. The Hyperspectral Smartphone is capable of accurate, laboratory- and field-based hyperspectral data collection, demonstrating the significant promise of both this device and smartphone-based hyperspectral imaging as a whole.
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.
