Look Out Below: A Case Study on Bone Tissue Structure and Repair

Mrs. Debbie Morgan is a 45-year-old female who works as a stocking clerk for a local

home improvement store. While she was at work today a large box of metal rivets fell

from a 20-ft.-high overhead shelf, striking her outstretched arm and knocking her to the

ground. The ambulance personnel reported that she had lost quite a bit of blood at the

accident scene and was “knocked out” when they arrived. To minimize further

hemorrhage, the paramedics applied a pressure bandage to her arm.

You meet the paramedics as they bring Mrs. Morgan into the emergency room and begin

to assess her for injuries. She is awake and alert, but complaining of severe left arm and

back pain, plus she has a “killer headache.” To fully examine her injuries you remove

four blood-soaked bandages from her arm. You notice a large open wound on her arm

with what appears to be bone tissue sticking out of the skin. She also has bruises covering

her left shoulder, left wrist, and lower back. To determine the extent of her injuries Mrs.

Morgan undergoes several x-rays, which reveal the following:

1) fracture of the left humerus at the proximal diaphysis,

2) depressed fracture of the occipital bone,

3) fracture of the 3rd lumbar vertebral body.
