Abstract:
Objective:To analyze the clinical efficacy of three-dimensional (3D) navigation-assisted percutaneous sacroiliac screw fixation in the treatment of Tile C1 pelvic fractures.Methods:A total of 12 patients with Tile C1 pelvic fractures who underwent percutaneous sacroiliac screw fixation assisted by 3D navigation in Liuzhou People's Hospital Affiliated to Guangxi Medical University from September 2019 to March 2022 were retrospectively analyzed. There were 8 males and 4 females, aged 43.08±16.93 years (range, 21-72 years). 24 patients with Tile C1 pelvic fractures who underwent fluoroscopy-assisted percutaneous sacroiliac screw internal fixation during the same period were selected as controls by pairing them according to age and sex in a ratio of 1:2. There were 15 males and 9 females, aged 45.75±11.69 years (range, 32-75 years). The operation time, intraoperative blood loss, number of screws, intraoperative fluoroscopy times, guide pin drilling times and pelvic function scores were compared between the two groups. The quality of pelvic fracture reduction was evaluated based on the Matta scoring criteria, the screw cut-out rate was calculated according to the Lonstein evaluation criteria, and the degree of postoperative heterotopic ossification was evaluated according to the Brooker grading system.Results:All patients were followed up for 18.1±4.7 months (range, 12-30 months). In the 3D navigation group, the operation time was 110.67±44.85 min, the number of intraoperative fluoroscopies was 24.42±9.94, and the number of guided needle drilling was 7.33±4.70, which was lower than 145.00±48.51 min, 75.75±29.47, and 13.92±5.78 in the fluoroscopically-assisted group, and the differences were statistically significant ( P<0.05). At the last follow-up, the Majeed pelvic function score of 3D navigation group was 89.08±3.89, and the excellent and good rate was 100% (12/12). The score of fluoroscopy-assisted group was 74.00±10.71, and the excellent and good rate was 79% (19/24). The difference was statistically significant ( χ2=10.23, P<0.001). The excellent and good rate of Matta grading was 92% (11/12) in the 3D navigation group and 79% (19/24) in the fluoroscopic assisted group, showing no significant difference between the two groups ( χ2=2.93, P=0.403). The screw cut-out rate and heterotopic ossification rate in the 3D navigation group were 17% (2/12) and 8% (1/12), which were lower than 71% (17/24) and 13% (3/24) in the fluoroscopy-assisted group, and the differences were statistically significant ( χ2=9.76, P=0.021; χ2=31.71, P<0.001). Conclusion:3D navigation-assisted percutaneous sacroiliac screw fixation for Tile C1 pelvic fractures can reduce the operation time and radiation exposure, improve the postoperative pelvic function, and reduce the incidence of screw cut-out and heterotopic ossification.
