Abstract:[Objective] To introduce the surgical technique and preliminary clinical outcomes of robot combined with lifting pin for re- duction and cannulated screw internal fixation of refractory femoral neck fracture. [Methods] From January 2018 to December 2020, 15 pa- tients were treated with the above techniques for refractory femoral neck fracture. First of all, 3 cannulated screw guide pins were placed un- der the guidance of robot, without passing through the fracture line, and a lifting pin was placed into the femoral head. The reduction force was applied by the lifting pin and manipulations to achieve satisfactory reduction of the fracture. Subsequently, the guide pin for cannulated screw guide were driven to pass through the fracture line into the femoral head, and finally the cannulated screws was inserted to finish the internal fixation. [Results] All the 15 patients had operation completed successfully, without neurovascular injury and other serious compli- cations, and were marked Harris score of (88.67±14.04) one year postoperatively. Except a patient who failed fixation due to premature walking, all the patients returned to their pre-injury activity level at the latest follow-up. In terms of imaging, all patients achieved grade I reduction based on Garden alignment scale after surgery. Except the patient abovementioned, all patients achieved fracture healing without femoral head necrosis. [Conclusion] The robot combined with lifting pin for reduction and cannulated screw internal fixation does effective- ly treat the refractory femoral neck fracture, with advantages of low radiation exposure, high fracture reduction quality and accurate internal fixation placement.
