Stan is a 35 year old man who is a dedicated long distance runner. He spends hours every week running along neighborhood streets.

stress fracture

the ischium and pubis
This joint is a complex and weightbearing joint, and is the most frequently injured joint in the body. The articular surfaces of the bones do not have complementary surfaces, so the stability of the joint depends mostly on its ligaments and the muscles that move the joint.
the knee joint
