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 surgery may be necessary to correct some type of physical defect that has developed, or to repair damage sustained due to an accident of some type. There are several different types of hip surgery that are commonly employed today, ranging from repair to a full hip replacement. Some forms of hip surgery are aimed at repairing fractures somewhere on the hipbone. Hip pinning and hip fixation are two examples.
