Differentiate the range of motion of hip flexion with the knee flexed and then with it extended. Passively flex the hip through its full range permitting the knee to flex. Then passively flex the hip with the knee straight. Note the differences in range and end feels. Why is there a difference in range of motion and what is this mechanical limitation called? What are the structures that limit hip flexion when the knee is in extension?

What bones, muscles, ligaments, and/or tendons do you think are affected? Why? Note: Since you are a physician, be sure to use the correct anatomical name(s) for muscles and bones (e.g. use "gluteus maximus" instead of "butt muscle").

Which type of diagnostic imaging will you use to determine if your prediction is correct? Why? Is there a known treatment for problem? If so, what would you prescribe?

Keep in mind that there may be multiple correct answers for each case study, as pain may be caused by a variety of factors. You are only required to describe one possible scenario and how you would proceed as a physician. Feel free to use any available resources to help you diagnose and treat your patients as accurately as possible.

Case Studies

Case Study #1 Age: 75 Sex: Female Report: The patient was admitted to the emergency room with complaints of severe right hip pain after falling down the stairs. The upper leg and hip area are swollen and bruised, and the patient is unable to put weight on the right leg. In addition, the patient has a family history of osteoporosis.

Case Study #2

Age: 23 Sex: Male Report: The patient was taken to the emergency room via ambulance after falling at a ski jump competition. The patient is describing severe pain in the back of the left knee with significant swelling. Onlookers reported hearing a faint popping sound when the patient fell.

Case Study #3

Age: 34 Sex: Male Report: The patient, a soccer player in the 2014 FIFA World Cup, is complaining of sharp pain in the back of the left thigh. The area is slightly swollen and tender to the touch, and the patient reports weakness in the left leg. Case Study #4 Age: 42 Sex: Female Report: The patient, a cyclist, fell off of her bike after hitting a pothole in the road. She extended her right arm to break the fall, then immediately had a sharp, persistent pain in her shoulder. Her arm and shoulder are sagging, and she is unable to lift her arm.

I need to answer questions ( very specifically ) 1. What did each of the bottles represent? What does the water represent? 2. What circulatory system structure do the check valves represent? What is their function in the circulatory system? 3. What do you predict would have happened if there were no valves present in the model? How would this affect the human body? Experiment 3: Modeling the Circulatory System In this experiment you will explore and model the structures and function of the circulatory system. Procedure 1. Use the permanent marker to label the plastic bottles 1 and 2. 2. Use a nail to carefully puncture two holes in the side of each bottle (approximately 3.5 cm from the bottom of the bottle) so that the holes are across from each other and at the same height from the bottom of the bottle. It is best to puncture the bottle with the nail straight through both sides. This will help keep the holes level. LAB SAFETY: BE EXTREMELY CAREFUL WHEN PUNCTURING THE BOTTLE. KEEP IN MIND WHERE YOUR HANDS ARE AT ALL TIMES. 3. You may need to maneuver the nail around the hole to make it large enough to fit the plastic tubing (Figure 7). The goal is for the tubing to fit tightly in the hole. 2 Check Valves 2 Drops of Dye Nail Permanent Marker 2 Plastic Bottles 60 cm of Tubing *Scissors *Water *You Must Provide Materials Figure 7: Maneuver the nail in a circular motion to enlarge the hole so that the tubing fits tightly. 386 The Circulatory and Respiratory Systems 4. Carefully cut the 60 cm tubing into four equal lengths of 15 cm. 5. Attach one end of one piece of 15 cm tubing to the OUT end of a check valve. 6. Attach one end of a second piece of tubing to the IN end of the check valve. 7. Repeat Steps 3 and 4 for the remaining check valve. 8. Construct a closed system by inserting the free ends of the tubes into the holes you created in the plastic bottles to create a loop. The tubes should be far enough into the bottle so that water can flow from tube to bottle to tube. The tubes in each bottle should not touch (Figure 8). Note: Properly assembled models should have the direction of the check valves facing in opposite directions. 9. Fill each bottle ¾ with water. The water level should be higher than the tubing. 10. Place the model on an underpad or paper towel to protect surfaces for the next step. This will also help catch water that leaks from the model. There should be minimal leaking if tubes are tightly in the bottles. 11. Place one drop of dye in each bottle and close the bottle by screwing on the caps. 12. Gently swirl the bottles to allow dye and water to mix. Be careful not to squeeze the bottles! 13. Note where the water is initially before squeezing the bottles and record your observations in Table 2. 14. Squeeze bottle 1 with both hands. Observe the direction of water flow and the water level in each bottle while you are squeezing and right after you stop squeezing. Record your observations in Table 2. 15. Repeat Step 13 for the bottle 2 and record your observations. 16. Squeeze one bottle and then the other back and forth.
