Effect of spaceflight on the human body for the astronauts. These joint torques and muscle forces could be used in conjunction with more fundamental computational simulations of bone remodeling and muscle adaptation in order to more completely model the end effects of such countermeasures, and determine whether a proposed exercise regime would be sufficient to sustain astronaut musculoskeletal health. The second effect of weightlessness takes place in human fluids. The body is made up of 60% water, much of it intra-vascular and inter-cellular. Within a few moments of entering a microgravity environment, fluid is immediately re-distributed to the upper body resulting in bulging neck veins, puffy face
Wrist arthroscopy patient's skin may be too fragile or atrophic. The traction brought about by the traction apparatus is then applied to three or even four fingers. The surgeon can either opt for dry arthroscopy or for wet arthroscopy. When performing a dry procedure the wrist can still, if necessary, be approached using open surgery. This may, for example, be required when a TFCC lesion is diagnosed. The latter is not possible when a wet procedure is performed, because the fluid that is used causes expansion of the tissue. To improve visualization within the wrist, an inflow irrigation system is used during
