Treatment of scaphoid fracture by closed reduction and internal fixation assisted by navigation robot

The scaphoid fracture is the most common type of wrist fracture. Delayed treatment after fracture often leads to nonunion. Because of its irregular shape, closed reduction and internal fixation is often difficult to achieve a good needle position and direction. With the rapid development of robotic navigation technology in recent years, it provides a better therapeutic effect for the treatment of scaphoid fracture with closed reduction and internal fixation.

There were 14 patients with scaphoid fracture (Herbert B 2) . From March 2020 to March 2023, all patients were closed reduction and internal fixation assisted by navigation robot. The time of operation was recorded, and the X-ray films were reexamined at 1,2,3 and 6 months after operation. The patients were evaluated with Cooney wrist score at 6 months after operation.

All patients were followed up. At 2 months after operation, 13 patients were healed, 1 patient was unhealed. At 3 months after operation, all patients were healed. The mean Cooney wrist score was 92.4 at 6 months postoperatively.

The navigation robot can locate and plan the direction of the needle and the point of insertion more accurately, and the operation time is shortened, and the fixation effect is reliable.
