Current Research:
Dr. Willis is involved in MRI assessment of femoral acetabular impingement (FAI) in children and adolescents. A pilot project has been completed, and his research team intends to continue the project over the next several years. The principal goals are to try to determine if adults develop FAI at a young age, and to predict if children with radiographic abnormalities will develop FAI as adults.
Biography:
Dr. Willis has been involved in various clinical projects for more than seven years while at CHEO. He continues to be associated with several clinical projects including evaluation of hip abnormalities in children and adolescents, post-traumatic deformities, and conditions of the foot and ankle.
