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 new stem cell technique could make hip replacements âa thing of the pastâ for some patients, says The Independent. Traditionally, people whose hip joint becomes worn or damaged over time need a mechanical implant fitted in place of their damaged joint. However, scientists are currently working on ways to repair the bone using stem cells.
