FIGURE 2.1. A 17-year-old man with mechanical right hip pain 2 years following closed treatment of a posterior column fracture of the acetabulum. (A) Anteroposterior (AP) radiograph shows evidence of posttraumatic degenerative changes with mild deformation of the femoral head. (B) A double-contrast iodinated contrast with computed tomography (Arthro-CT) scan confirms the presence of multiple loose bodies represented by the numerous filling defects (arrows) posteriorly on this image through the joint. (C) Arthroscopic view reveals several of the representative loose bodies between the femoral head and acetabulum. (C, from Byrd,34 with permission of Arthroscopy.)

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
