Tips for using the site with students      

  1. Before using this activity in class (or at home with your kids) go through the activity once to make sure it works correctly on your computer(s). This activity is recommended for broadband internet access - expect load times between 15 seconds and 1.5 minutes depending on your internet connection. If the activity does not load after clicking the 'start' button, you may be asked to download a Flash Player from Adobe.com. Please click yes, as this allows you to view the Edheads Virtual Hip Replacement Surgery.

  2. If you are using an iPad or other iDevice, our games will not play without downloading an app or browser. We recommend the Photon browser available at: https://itunes.apple.com/us/app/photon-flash-player-for-ipad/id430200224?mt=8.

  3. Your computer(s) will need to have some sort of sound output. Either speakers or headphones will work well. The majority of this activity has voice audio. We highly recommend headphones in a classroom setting.

  4. Students in the target grade-range will take approximately fifteen minutes to complete surgery working individually or in groups of two to three. Some students can get queasy using this activity, particularly when looking at the photos of real surgery. We recommend closely monitoring students when they experience this activity for the first time.

  5. After students use the site, teachers may want to discuss with their class why certain steps of surgery occurred in the order they did, or why these steps were performed at all. Asking questions such as “Why do you think the Operating Room team asks the patient to do math (counting backwards by 7s) during the surgery?” will get students thinking about WHY various steps exist or why they are accomplished as they are. Teachers can also ask questions such as, “What do you think the FIRST brain surgery was like and how do you think it differed from today’s surgery?”

Answers to Quiz Questions 

Q1. Which hip do you think needs surgery?
A1. The patient’s right hip (the one on the left in the x-ray).

Q2. Why is it critically important to protect the sciatic nerve throughout this procedure?
A2. The patient won’t be able to use her leg again if this is severely damaged or cut. 

Q3. Why should we try to ream more towards the top of the acetabulum?
A3. The worn, or sclerotic, bone at the top of the cup is harder to ream than the bone at the bottom.

Q4. Why does the plastic liner offer more coverage at the top, back part of the cup?
A4. This extra coverage prevents the most common form of dislocation.

Q5. Why does the patient have osteophytes?
A5. The hip bones compensate for excessive wear by growing osteophytes.
