The primary focus of Dr. Hodgson’s work is on computer-assisted orthopaedic surgery; the main goal is to improve the accuracy of performing surgical tasks (such as placing implants or reducing fractures) while minimizing use of and exposure to radiation and decreasing operative time. We are currently working in three main areas: 1. Using ultrasound to accurately locate bone surfaces in trauma and spinal surgery, 2. smart C-arm technologies to operate more accurately, efficiently and with less radiation exposure, and 3. bone-mounted robots for unicompartmental knee replacement surgeries.
