Dr. Nicolae Mihailide, father of Catalina, grade 12, and an orthopedic surgeon based in Romania, visited Anita Chetty’s human anatomy and physiology classes on Jan. 3 to give presentations on his profession and offer insight into various surgical procedures. Using projected x-ray images from past procedures, Mihailide asked students to identify the problems with the patients in the images. He then explained the procedure, providing samples of prosthetics used in the operations.
