The International Perthes Study Group is a group of international specialists and researchers with a common goal of advancing knowledge and care of patients with Perthes disease. The IPSG unites specialists worldwide to gather and discuss varied experiences and opinions.

Perthes disease is a rare disease involving the loss of blood flow to the femoral head, or the ball of the hip joint. This disease affects children and can cause pain and deformation of the hip joint. Early intervention and specialized care from a pediatric orthopaedic surgeon can have a large impact on the outcome.

The International Perthes Study Group seeks to answer questions to help better understand and treat Perthes disease. We accomplish this by bringing many specialists and researchers together to collect and evaluate data. We also strive to engage patients, parents, and caregivers to ensure the research is relevant and evidence based.
