Case Study 8
Appendicular Skeleton
Kelli Menard

Summary:
Nicole a 14 yr old sustained a fracture that was a compound, tibial-fibular fracture just below the knee. The x-ray showed there was a meniscal tear above the knee where the fracture was. Nicole stayed in the hospital for 14 days due to infection where the bone was through the skin. Once the infection subsided she was put into a cast. She was put in the cast for three month which then she was able to bear weight on her leg. Her leg healed but her tear in her meniscus did not heal, she had water in her knee. It is still torn after 6 months from her injury. Abnormal vs. Normal:

( Tibia (Shinbone) Shaft Fractures)
Water in the knee from meniscus tear (Meniscus Tear)
(Meniscal Tears)

Questions:
1.) The term tibial-fracture means a fracture or break on the upper part of the shin bone near the knee. These kinds of fractures may lead to tissue damage near the area of the injury. (Fractures of the Proximal) 2.) A compound fracture, also known as an open fracture is when there is a break in the skin around the fracture. A compound fracture to be classified as a compound is when the air, and bacteria must be able to get to the fracture site.( Compound Fractures) 3.) Her fracture is more likely to get infected than any other fracture because she sustained a compound fracture. A compound fracture is when a fracture occurs that breaks through the skin for air and bacteria to get into the skin. With a fracture like this the moment when the skin is broken open the bacteria can get into the skin causing an infection. 4.) The microscopic features of the osseous tissue that help long bones with stand lateral stress without breaking are: (Skeletal System) * Lateral stress- which causes compression on the leg

* Bony collar- experiences the most stress on the lateral impact. It withstands compressive crushing by hydroxyapatite crystals in its extracellular matrix, these are like weight...
