.... Artificial joints are used to replace diseased biological joints in hips, knees, shoulders, elbows, wrists, fingers, and so on. The typical hip joint implant is composed of four components: a stem, head, insert, and shell ( Fig. 1 ). Other joints have similar components but different geometries. A stem...
