ANS: A A stress fracture occurs in normal or abnormal bone that is subjected to
repeated stress, such as repetitive and strenuous activities that occur during athletics. A
greenstick fracture is one in which the outer surface of the bone is disrupted but the

pathologic fracture is one that occurs from force that would not usually break a bone.
There is usually an underlying lesion or abnormality at the site of the fracture.
