Abstract:
Objective:To investigate the efficacy of biplane double-supported screw fixation in the treatment of femoral neck fractures in the middle-aged and young patients with the assistance of TiRobot.Methods:A retrospective analysis was conducted of the 28 young and middle-aged patients with femoral neck fracture who had been treated by biplane double-supported screw fixation at Department of Traumatic Orthopaedics, Puren Hospital from January 2021 to January 2022. According to the intraoperative use of TiRobot-assistance in the nail placement, they were divided into 2 even groups ( n=14). In the observation group where a TiRobot was used to assist nail placement, there were 6 males and 8 females, with an age of (44.1±8.7) years. In the control group where nail placement was monitored by conventional C-arm fluoroscopy, there were 7 males and 7 females, with an age of (48.8±8.0) years. The 2 groups were compared in terms of operation time, intraoperative fluoroscopy times, intraoperative blood loss, hospitalization time, fracture healing time, postoperative complications and hip function 6 months after operation. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The operation time, intraoperative fluoroscopy times, intraoperative blood loss and hospitalization time in the observation group were significantly less than those in the control group [(66.5±3.7) min versus (77.1±3.9) min, (12.8±1.6) times versus (18.7±2.5) times, 3.5 (2.8, 4.0) mL versus 26.0 (24.0, 27.3) mL, (9.4±1.2) d versus (11.3±1.2) d] ( P< 0.05). During the follow-up period, the fractures healed well in both groups with no obvious complications. The fracture healing time in the observation group was (6.1±1.2) months, insignificantly shorter than that in the control group [(6.3±1.1) months] ( P>0.5). The Harris hip score 6 months after operation in the observation group (92.6±2.7) was significantly higher than that in the control group (90.6±1.9) ( P< 0.05). Conclusions:In the treatment of young and middle-aged patients with femoral neck fracture, the biplane double-supported screw fixation assisted by a TiRobot can shorten operation time and hospitalization time, and reduce the intraoperative fluoroscopy times and intraoperative blood loss for the patients, more conducive to the functional recovery of the hip joint, leading to better surgical efficacy than the nail placement monitored by conventional C-arm fluoroscopy.
