The annual Charles F. Gregory Memorial Lecture is dedicated to the memory of the first Division Chief of the Department of Orthopaedic Surgery at UT Southwestern Medical Center. He served as Chief from 1956 until 1976 and ushered in our first Academic Orthopaedic program that we follow today. This year's guest speaker is Dr. Regis O'Keefe, MD, PhD, Professor and Chair, at the Department of Orthopaedic Surgery, Washington University, St. Louis, MO. He is a well-known orthopaedic oncologist with a strong leadership and basic science background. The attendees will be able to understand the current role of the Orthopaedic Surgeon in terms of Patient-Reported Outcomes and the basic science of Periosteal tissue. One graduating resident and next years graduates will present their best scholarly activity while a resident physician. They will cover a number of current orthopaedic topics of interest to orthopaedic surgeons including Hip replacement in HIV patients, Pulmonary Embolism in Trauma patients and physeal bar resection in pediatric patients to help with limb length inequality.
