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 aspiration of the ganglion with or without injection of a steroid. In some cases the ganglia are associated with serious loss of wrist function or weakness in the affected finger, which makes a surgical intervention highly indicated. Resection of dorsal ganglion are still widely treated with open surgery. However, recent studies show that treatment with an arthroscopic intervention is a reasonable alternative. Arthroscopic intervention has the advantages of smaller incisions, faster recovery of wrist function and less pain postoperative. Overall outcome of arthroscopy is not superior to the outcome in open surgery. Recurrence rates and final wrist function are similar.
