c. The fracture line is perpendicular to the bone. d. The fracture line is vertical to the shaft of the bone. ANS: B A transverse fracture occurs straight across the bone. A linear fracture runs parallel to the long axis of the bone. A transverse fracture runs straight across the bone, not perpendicular. A transverse fracture runs straight across the bone, not vertically. REF: p. 979 3. A 70-year-old female with osteoporosis fractures her leg at a location of preexisting abnormality. She reports that the fracture occurred following a minor fall. Which of the following best describes the fracture? a. Fatigue fracture b. Stress fracture c. Pathologic fracture d. Greenstick fracture ANS: C A pathologic fracture is a break at the site of a preexisting abnormality, usually by force that would not fracture a normal bone. A fatigue fracture is caused by abnormal stress or torque applied to a bone with normal ability to deform and recover. Stress fractures occur in normal or abnormal bone that is subjected to repeated stress, such as occurs during athletics. A greenstick fracture perforates one cortex and splinters the spongy bone. REF: p. 979 4. A 32-year-old obese male begins a jogging routine. A week after beginning, he fractures his leg. This is referred to as a what type of fracture? a. Comminuted b. Greenstick c.

A comminuted fracture is one in which a bone breaks into two or more fragments. A greenstick fracture perforates one cortex and splinters the spongy bone. An open fracture is a complete and incomplete fracture that breaks through the skin. REF: p. 980 5. Transchondral fractures are most prevalent in: a. Adolescents b. Older adults c. Infants d.
