Explore the SORG Research Group

Overview

The SORG Orthopaedic Research Group (previously Skeletal Oncology Research Group) has grown beyond musculoskeletal oncology. SORG was founded and is directed by Dr. Joseph Schwab and co-directed by Dr. Hamid Ghaednia in the Department of Orthopaedic Surgery at Massachusetts General Hospital in Boston.

Our research group has developed some the world’s leading predictive algorithms for spine disorders and musculoskeletal oncology. Additionally, SORG manages Mass General Brigham’s Orthopaedic Registries (MGBOR) and develops biomedical devices and wearables (CPAI). Learn more about our ongoing research.

Our Current Research Projects

SORG Predictive Algorithms

SORG leverages technological advancements in artificial intelligence and data science to gain insight into patient outcomes of orthopaedic surgery. Our predictive models are recognized and accessed around the world. Access our models.

SORG Clinical Studies

Learn more about clinical studies currently underway at SORG.

Social Determinants of Health (SDOH)

Social structures and socioeconomic patterns may be the most powerful factors determining the recovery of patients with musculoskeletal impairments. These factors can be categorized into social determinants of health (SDOH) and include economic stability, living environment, educational attainment, access to care and social support. Learn more about our research into the social determinants of health.

The Center for Physical Artificial Intelligence (CPAI)

The Center for Physical Artificial Intelligence brings together cutting-edge technology and clinical expertise to develop groundbreaking devices that reshape the way we think about assessing health. Learn more about CPAI.

Mass General Brigham Orthopaedic Registries

SORG is responsible for managing the Mass General Brigham Orthopaedic Registries, incorporating both traditional and novel methods to drive new insights into patient outcomes in orthopaedic surgery. Visit the MGB Orthopaedic Registries website.
