Abstract:
OBJECTIVE:To investigate the effectiveness of TiRobot-assisted minimally invasive treatment for fragility fractures of the pelvis (FFP) in elderly patients.
METHODS:A retrospective analysis was conducted on the clinical data of 176 patients with FFP who were admitted between July 2018 and July 2024 and met the selection criteria. Among them, 95 patients underwent TiRobot-assisted closed reduction and minimally invasive cannulated screw fixation (robot group), while 81 patients underwent traditional open reduction and plate screw fixation (control group). There was no significant difference in baseline data such as gender, age, fracture classification, disease duration, and preoperative visual analogue scale (VAS) pain scores between the two groups ( P>0.05). The following parameters were recorded and compared between the two groups, including operation time, intraoperative blood loss, intraoperative transfusion rate, volume of intraoperative blood transfusion, maximum incision length, hospital stay, maximum residual displacement, reduction quality, fracture healing time, incidence of complications, VAS scores, Majeed pelvic function scores, and functional grading.
RESULTS:All surgeries in both groups successfully completed. The robot group exhibited significantly shorter operation time, reduced intraoperative blood loss, lower intraoperative transfusion rate, smaller volume of intraoperative blood transfusion, shorter maximum incision length, and shorter hospital stay compared to the control group ( P<0.05). In the robot group, a total of 14 INFIX internal fixation frames and 280 cannulated screws were implanted, among which 250 screws were rated as excellent, 17 as good, and 13 as poor, resulting in a screw placement excellent and good rate of 95.36%. Radiological review revealed that the excellent and good rate of reduction quality was in 91.58% (87/95) in the robot group and 81.48% (66/81) in the control group, with no significant difference in postoperative maximum residual fracture displacement or reduction quality between the two groups (P>0.05). All patients in both groups were followed up 12-66 months, with an average of 28.9 months, and there was no significant difference in follow-up time between the two groups ( P>0.05). The fracture healing time in the robot group was significantly shorter than that in the control group ( P<0.05). At last follow-up, both groups showed significant improvement in VAS scores compared to preoperative values ( P<0.05); the change values of VAS scores, Majeed scores, and the excellent and good rate of Majeed pelvic function were significantly higher in the robot group than in the control group ( P<0.05). Regarding postoperative complications, there was no significant difference between the two groups in terms of gait changes, secondary surgeries, heterotopic ossification, incision infections, walking difficulties, internal fixation failure, or mortality rates ( P>0.05); however, the incidence of delayed wound healing was significantly lower in the robot group than in the control group ( P<0.05).
CONCLUSION:TiRobot-assisted minimally invasive treatment of elderly FFP is superior to traditional open reduction and internal fixation in terms of surgical trauma control, postoperative rehabilitation speed, and functional recovery.
