Skeletal System Case Study: Broken Leg. DUE: Wednesday, September 30, 2015Main Issue: 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. Her immobilized leg was casted and 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:Answer each question with a well thought out answer. In brackets behind each question is a code for the outcome being assessed and the marks the question is worth. What does the term “tibial-fibular fracture” mean? (HB2 1 mark)What is a compound fracture? Provide a diagram. (HB2 2 marks)What kind of x-rays (radiographs) would have likely been taken? What angles of the injury would provide the most detail? Why is this likely? (Remember shadows) (DT1 2 marks)What kind of protection would have had to be worn by those doing the x-ray? (DT1 1 mark)What occupations likely were involved in the taking of the x-ray? (CE1 1 mark)What features of the knee joint structure help minimize friction between the thigh bone and the leg bone. (HB1 2 marks)Describe the changes a broken bone undergoes as it is healing. (HB2 3 marks)Why did Nicole’s bones heal much more quickly than her cartilage? (HB2 2 marks)Assignment total = 14 marksBibliography This work is adapted from: Sandmire, D. (2000, January 1). Case Study #5. Retrieved September 10, 2014, from ................
