Robot-assisted percutaneous cannulated screw treatment versus traditional surgical reduction fixation in the treatment of Hawkins type Ⅱ talus fracture: a retrospective study of an average two-year follow-up

This study aimed to evaluate and compare the efficiency, safety and accuracy of robot-assisted internal fixation and traditional freehand percutaneous screw in talar neck fracture treatment. This study included 23 patients in the robot-assisted group and 23 patients in the traditional group. Age, injured side, average post-operative follow-up time, time from injury to surgery, operation time, intraoperative blood loss, intraoperative fluoroscopic dose, fracture healing time, American Foot and Ankle Surgery Association (AOFAS) ankle-hindfoot score, Visual Analogue Scale (VAS) score and 12-item Short-Form Survey (SF-12) score were recorded and compared. This study revealed no statistical difference in baseline characteristics between the two groups, as well as the average post-operative follow-up time, injury to operation time, intraoperative blood loss, fracture healing time, VAS score, 12-item Short-Form Survey (SF-12) score and AOFAS score ( P > 0.05). A significant difference was found between the robot-assisted group and the traditional group at the time of operation and intraoperative fluoroscopic dose ( P < 0.05). Robot-assisted screw placement for talar neck fractures achieved clinical outcomes comparable to those of traditional surgery, with the advantages of significantly shorter operation time and lower intraoperative fluoroscopic dose. Robot-assisted surgery appears to be a safe, effective, and low-radiation alternative for selected talar neck fractures (Hawkins type II).
