Abstract: [Objective] To introduce the surgical technique and clinical results of robot combined with interactive closed reduction of femoral head and shaft in the treatment of irreducible femoral neck fracture.[Methods] From January 2018 to December 2020, our department used robot combined with interactive closed reduction of femoral head and stem to treat 15 cases of refractory femoral neck fractures. Firstly, three guide pins in the femoral neck and one guide pin in the head are inserted with the assistance of robot, and then the rocker guide pin and the distal end of the fracture are interactively adjusted under fluoroscopy. When the fracture is satisfactorily reduced, the three guide pins are fixed through the fracture line, and finally the hollow screw is fixed. [Results] The average operation time was 59.60 min, the average fluoroscopy of patients and operators were 20.87 and 6.27 times, the average bleeding was 10.40 ml, and the average placement of guide needle was 6.0 times. The average included angle of any two screws on the X-ray film of hip joint: positive position 2.35 °, lateral position 2.53 °, the average included angle between each screw and the axis of femoral neck: positive position 3.85 °, lateral position 3.87 °. One patient had internal fixation failure, and the rest had no complications such as infection, internal fixation failure and femoral head necrosis. The average healing time was 6.29 months. One year after operation, the average Harris score of hip joint was 88.67, and the excellent and good rate was 93.33%. [Conclusion] Robot combined with femoral head and stem interactive closed reduction technology has successfully treated refractory femoral neck fractures. It has many advantages including low radiation damage, high fracture reduction quality, high internal fixation accuracy and good hip function.
