Our Current Fellows

The SORI fellowship program is a key component of our clinical and research initiatives. We host up to three clinical research fellows and one research fellow at any given time, along with additional observerships, all from diverse backgrounds across the globe. These fellows gain invaluable skills and experience during their time at SORI, contributing to research advancements through publications and presentations. The knowledge they acquire strengthens orthopaedic practices in their home countries, enabling them to bring back innovative ideas and improved techniques that benefit their communities.
