Pulmonary hypertension (PHT) is high blood pressure in the heart-to-lung system that delivers fresh (oxygenated) blood to the heart while returning used (oxygen-depleted) blood back to the lungs. Pulmonary versus systemic blood pressure.
Two types of surgery are used. 1  Hip repair (internal fixation). 2  Hip repair involves stabilizing broken bones with surgical screws, nails, rods, or plates. 3  This type of surgery is usually for people who have fractures in which the bones can be properly aligned.
There is an alternative type of surgery to hip replacement, known as hip resurfacing. This involves removing the damaged surfaces of the bones inside the hip joint and replacing them with a metal surface. An advantage to this approach is that it removes less bone.
