| Patients undergoing foot/ankle joint surgery after March 2023 at Chiba University Hospital are eligible. On the day of surgery, the distance from the skin to the superficial/deep fibular nerve is measured using ultrasonography before surgery. Also measure the distance from the lateral edge of the third peroneal tendon for the superficial peroneal nerve, and the distance from the lateral edge of the extensor hallucis longus tendon for the deep peroneal nerve. After anesthesia, the same measurements are taken again, and the amount of change before and after anesthesia is calculated to determine the amount of nerve migration. | — |
