Patella fracture an MRI may be required. Treatment may be with or without surgery, depending on the type of fracture. Undisplaced fracture can usually be treated by casting. Even some displaced fractures can be treated with casting as long as a person can straighten their leg without help. Typically the leg is immobilized in a straight position for the first three weeks and then increasing degrees of bending are allowed. Patellectomy (in cases of comminuted fracture) is removal of the entire patella, whereas a partial patellectomy is removal of only a portion of the patella, while any ligaments or tendons that had
Effect of spaceflight on the human body reduce their aerobic capacity, and slow down their cardiovascular system. As the human body consists mostly of fluids, gravity tends to force them into the lower half of the body, and our bodies have many systems to balance this situation. When released from the pull of gravity, these systems continue to work, causing a general redistribution of fluids into the upper half of the body. This is the cause of the round-faced 'puffiness' seen in astronauts. Redistributing fluids around the body itself causes balance disorders, distorted vision, and a loss of taste and smell.
