Case Discussion Case discussion from WST The Summit 2026 in which Stefan Hemmer presents a 14-year-old girl with severe double major adolescent idiopathic scoliosis (AIS): a 73-degree thoracic and 72-degree thoracolumbar curve, unbalanced shoulders and good flexibility on bending and traction X-rays. He summarizes how to choose the upper instrumented vertebra (UIV) by Lenke type and shoulder level

Surgical Demonstration In this session, Julian Leong and Stephan Hemmer present contemporary techniques for apical correction in Adolescent Idiopathic Scoliosis (AIS). Through case discussions and a live surgical demonstration, they explore direct vertebral derotation, differential rod bending, anterior growth arrest, sublaminar band technology, and pedicle screw strategies. The faculty shares pra

Case Discussion In this case-based discussion, Julian Leong presents the surgical planning and correction strategy for a severe, stiff thoracic scoliosis with marked hypokyphosis in a skeletally mature patient from one of his cases. The faculty discuss key decision points including fusion levels, restoration of thoracic kyphosis, anterior release, Ponte osteotomies, rod contouring, positioning, ne

Surgical DemonstrationPatient-specific alignment techniques in total knee arthroplasty are explored. The session discusses mechanical, kinematic, and functional alignment techniques, emphasizing the importance of balancing flexion and extension gaps. It details the surgical procedure, including robotic arm positioning and landmark marking. The efficiency of robotic systems and the future integrati

Surgical DemonstrationIn this session, a total knee arthroplasty (TKA) with the usage of a robotic-assisted system is shown. The system is designed to facilitate consistent, efficient procedures through improved cuts and patient specific alignment compared to manual total knee arthroplasty. This session was part of the DKOU 2023 and was featured by DePuy Synthes #alignment #arthroplasty #robotic #

Surgical Demonstration In this live demonstration, expert surgeons are discussing the retrograde nailing technique. They detail a specific C2 distal femur fracture case, covering incision preparation, exposure techniques, and the use of clamps and tools. The session emphasizes indirect reduction of fractures, anatomical reduction, and post-surgery care, including the use of hinged knee braces.This
