Why did the vampire drive on the motorway? Someone told him it was a main artery!

OUCH... 

Now tell me which bones were involved in this little accident.

Daily Blog Thoughts Part I

Just wanted to CLARIFY where red blood cells are made.

Blood is Made in the Bone Marrow
All of the cells in the blood, red blood cells, all types of white blood cells, and platelets are made in the bone marrow. This happens primarily in the flat bones in your body such as the skull, the sternum, and the pelvis.

Blood Cell Development
All of the cells differentiate from one group of "master cells" called stem cells. The stem cells can become whatever kind of blood cell the body needs. They come under the influence of factors in their environment to become red cells, white cells, or platelets.

DAILY BLOG THOUGHTS - PART II

Chief Complaint: 14-year-old girl admitted with a broken left leg.

History: Nicole Michaelson, a 14-year-old girl, was skiing when she fell and broke her left leg. As she fell, her left leg got caught under the body of another skier who ran into her. An X-ray revealed that the fracture was a compound, tibial-fibular fracture just below the knee. The X-ray also revealed a torn meniscal cartilage in the knee above the fracture. The girl remained in the hospital for 14 days because of an infection of the leg in the area of skin breakage. Her immobilized leg was casted after the infection subsided. She remained in a full leg-length cast for 3 months, after which the upper portion of the cast was removed and she was allowed to start bearing weight on the leg. The bones ultimately healed, but the girl continued to have left knee swelling ("water on the knee") and pain made worse by walking. Arthroscopic examination of the knee revealed a meniscus that was still torn 6 months after her injury.

Questions:

1. What does the term "tibial-fibular fracture" mean?

2. What is a compound fracture?

3. Why was her injury more likely to become infected than a routine fracture of the leg?

4. Describe the microscopic features of osseous tissue that help long bones withstand lateral stress without breaking.

5. Describe the changes a broken bone undergoes as it is healing.

6. How does weight-bearing influence the bone repair process you described above? (i.e. what effect does weight-bearing have on the orientation of the Haversian systems?)

HOMEWORK
