Abstract:
Objective To explore the therapeutic effect of orthopedic robot assisted percutaneous cannulated screw internal fixation in the treatment of Tilt pelvic fractures.Methods A retrospective analysis was made on clinical data of 21 cases of Tilt pelvic fractures treated with"Tianji"orthopedic surgical robot combined with 3D C-arm fluoroscopy assisted percutaneous cannulated screw internal fixation from January 2020 to October 2023.The Tile classification included 11 cases of type B2.1,3 cases of type B2.2,2 cases of type B2.3,and 5 cases of type B3.Results The percutaneous insertion of cannulated screw was safe in all the 21 cases,with a total of 71 screws inserted,including 21 S1 screws,21 S2 screws,21 pubic branch screws(14 anterograde screws and 7 retrograde screws),4 LC-Ⅱ screws,and 4 modified LC-Ⅱ screws.The insertion time of a single screw was(31.1±10.8)min,the fluoroscopy time of a single screw was(5.9±1.7)min,the surgical time was(100.7±16.2)min,and the bleeding volume was(11.2±4.2)ml.According to the Matta criteria,8 cases had excellent fracture reduction quality,11 cases were good,and 2 cases were fair,with an excellent and good rate of 90.5%(19/21).According to the Gras classification,the quality of screw placement was excellent in 65 cases and good in 6 cases,with an excellent and good rate of 100%(71/71).The 21 cases were followed up for 4-18(mean,10.7±8.4)months.The bone healing was achieved in all the cases,with a fracture healing time of(12.7±1.8)weeks.At the last follow-up,according to the Majeed scoring system,7 cases were rated as excellent pelvic function,11 cases as good,and 3 cases as fair,with an excellent and good rate of 85.7%(18/21).Two cases of lateral femoral cutaneous nerve injury and two cases of intermuscular vein thrombosis were cured.Conclusion The use of orthopedic robot assisted percutaneous cannulated screw fixation for the treatment of Tilt pelvic fractures has satisfactory therapeutic effects,with accurate screw placement and no need for adjustment.
