NASA's New Horizons flyby mission of the Pluto-Charon binary system and its four moons provided humanity with its first spacecraft-based look at a large Kuiper Belt Object beyond Triton. Excluding this system, multiple Kuiper Belt Objects (KBOs) have been observed for only 20 years from Earth, and the KBO size distribution is unconstrained except among the largest objects. Because small KBOs will...
Supracondylar fractures are the most common in children. A visible posterior fat pad is the best clue to their presence. Significant displacement is associated with neurovascular complications. Lateral mass fractures are not common but are easily overlooked with devastating consequences. Medial avulsion injuries can be subtle if displaced into the joint. The mnemonic CRITOL tells us that if we see...
Pluto and its satellites will be the most distant objects ever reconnoitered when NASA’s New Horizons spacecraft conducts its intensive flyby of this system in 2015. The size-frequency distribution (SFD) of craters on the surfaces in the Pluto system have long been expected to provide a useful measure of the size distribution of Kuiper Belt Objects (KBOs) down to much smaller size scales than presently...
