Sven Olerud has passed away at the age of 96. Sven was the inventor of both of Anatomicas systems for instrumented spinal surgery (Olerud Cervical och Olerud PF). He had a long career within the orthopedic field in Bergen, at Karolinska and finally at Akademiska Hospital. He was one of the leading orthopedic surgeons. During the 1980s and 1990s Sven developed several implants with the help of his great knowledge of biomechanics. These implant systems are still sold by Anatomica. We remember Sven with warmth and we are very thankful for his efforts within the orthopedic field.
