Shadow zone is an area where seismograph can not be detect earthquake after the seismic wave have passed through the earth. When earthquake strikes, seismic wave radiate out spherically from the earthquake's epicenter. At the angular distances of 104 degree to 140 degree from the earthquake focus, any direct P waves are not received.
Questions about bending over after Hip replacement. I just read in another thread a reminder of not bending over for 6 weeks after surgery. It has prompted this question. I guess I should ask the PT, but I'd also like input from folks who have been there. First, let me tell you about my job.
After my total hip replacement, how long do I need to follow hip precautions (i.e. no bending greater than 90 degrees at the hips, no twisting, no crossing the legs)? You should follow hip precautions for 6 weeks after you leave the hospital. Surgery, particularly on the lower extremities, increases the risk of blood clots. You are taking Coumadin, a blood thinner, to decrease the risk of blood clot formation. You will take Coumadin for 6 weeks after surgery.
