Urgent Advice • Around this time, you will be tempted to focus on lab. However, next month is the hardest test of the year: muscle lab exam. There are 75 muscle names, origins, insertions, and actions to learn in 3 weeks. That means you have to memorize 3 a day, 6 days a week, starting right after the bone lab exam. • If you are behind in lecture, you will want to focus on lecture and you will not memorize 3 muscle OIA’s a day. As soon as the lecture exam is over, there will only be 2 weeks until the hard lab exam, and you will have to memorize 6 OIA’s per day. That may seem easy, but 3 a day is challanging and 6 per day is very difficult. • The solution is to keep up in lecture, and start memorizing 3 OIA’s a day right after the lab exam.

Turning An Ankle Into A 'Knee' • Patient was a five-year-old girl with Ewing's sarcoma, a cancerous tumor, behind her left knee. Surgeons at The Children's Hospital of Philadelphia used a limb-sparing technique called rotationplasty to remove the diseased portion of bone, turn the shortened portion of the leg bone in a half-circle and reattach it, with the ankle joint functioning as a knee. • With a prosthetic attached to the mobile joint, the child, now 13, enjoys gymnastics and cheerleading.
