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.
The purpose of total hip replacement is to remove the two damaged and worn parts of the hip joint- the hip socket (acetabulum) and the ball (femoral head) â and replace them with smooth, artificial implants called prostheses, which help make the hip strong, stable, and flexible again.
