Developmental dislocation of the hip (DDH) is a major cause of disabilities in children. Open surgery is often needed to re-shape (osteotomy) the hip socket/femoral head and move the femur back into place. DDH surgery is complex and can cause avascular necrosis and re-dislocation. Improving accuracy of DDH operation is a major challenge in paediatric orthopedics. Our pilot work achieved precise osteotomy with a 3D-printed navigation template. This project will further explore precise osteotomy methods, which can lead to individualized precise surgical methods of higher success rates for DDH.
