Hip arthroscopy is around the outside of the hip (greater trochanter), although inflammation of iliopsoas (the muscle which passes directly over the front of the hip) can also occur. As with all arthroscopic procedures, because the hip arthroscopy is undertaken with fluid in the joint, there is a risk that some can escape into the surrounding tissues during surgery and cause local swelling. Occasionally, this causes skin blistering. However, swelling usually resolves after 24 hours without intervention. Very rarely some of this irrigation fluid can track upwards into the abdomen. Should this occur, the patient may complain of back pain immediately after
Effect of spaceflight on the human body as with previous stations and spacecraft, and may not suffer from feelings of isolation in the same way. The sum of human experience has resulted in the accumulation of 58 solar years in space and a much better understanding of how the human body adapts. In the future, industrialisation of space and exploration of inner and outer planets will require humans to endure longer and longer periods in space. The majority of current data comes from missions of short duration and so some of the long-term physiological effects of living in space are still unknown. A round trip to Mars
