Objective:To explore the efficacy of the intelligent visualization system combined with pelvic unlocking reduction frame assisted reduction and fixation in the treatment of unstable pelvic fractures.Methods:A retrospective analysis was conducted on the data of 11 patients with unstable pelvic fractures who were treated with the Holosight intelligent visualization system combined with the pelvic unlocking and reduction frame in the Orthopaedics Department of Jinan Third People's Hospital from May 2023 to June 2024. There were 8 males and 3 females, with an age of 49.91±18.81 years (range, 15-75 years). Tile classification: 1 case of B1 type, 7 cases of B2 type, and 3 cases of C1 type. Among them, there were 10 cases of anterior ring injury, 9 cases of posterior ring injury, 1 case of pubic symphysis separation, and 4 cases of iliac bone fracture. The time from injury to surgery was 3.36±1.32 d (range, 2-7 d). Record the effective fluoroscopy times during the operation, single screw insertion time, operation time, blood loss, and relevant data during postoperative follow-up (including fracture reduction quality, fracture healing time, postoperative functional recovery, and complications). The Matta imaging scoring criteria were used to evaluate the quality of fracture reduction, and the Majeed scoring system was used to assess postoperative pelvic function.Results:All 11 patients successfully completed the surgery, with a duration of 115±5 min (range, 85-185 min); single screw insertion time 6.09±2.02 min (range, 3-11 min); the effective fluoroscopy frequency was 8.56±4.98 times (range, 4-20 times); the intraoperative blood loss was 20.45±12.74 ml (range, 10-50 ml). Three cases were fixed using an internal fixation system (INFIX), seven cases were fixed using anterior ring channel screws, eight cases were fixed using sacroiliac screws, and four cases were fixed using LC-II screws. All patients were followed up for 6.82±3.25 months (range, 6-12 months), and the fracture healing time was 4.36±1.12 months (range, 3-6 months). There were no complications such as internal fixation fracture, screw loosening or retraction, infection, nerve injury, or active bleeding. According to the Matta imaging reduction evaluation criteria, the results were excellent in 6 cases, good in 4 cases, and fair in 1 case. At the last follow-up, the Majeed score was 94.36±5.63 points (range, 83-99 points). The results showed that 9 cases were excellent, 2 cases were good.Conclusions:The intelligent visualization system and pelvic unlocking reduction frame assist in the treatment of unstable pelvic fractures, which have the advantage of visualizing the surgical process, improving the reduction efficiency and precise insertion rate of channel screws, with minimal trauma, less bleeding, low infection rate, fast postoperative recovery, and reduced radiation exposure risk for both doctors and patients.
