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.
A hemiarthroplasty is an operation that is used most commonly to treat a fractured hip. The operation is similar to a total hip replacement, but it involves only half of the hip. (Hemi means half, and arthroplasty means joint replacement.) The hemiarthroplasty replaces only the ball portion of the hip joint, not the socket portion. In a total hip replacement, the socket is also replaced.
