[Effect of computer virtual technique combined with pelvic reduction frame in the treatment of type C pelvic fracture].

OBJECTIVE

To investigate the short-term clinical effect of the computer virtual technique combined with pelvic reduction frame in the treatment of complex pelvic fractures.

METHODS

Thirty patients with Tile C pelvic fractures treated by percutaneous minimally invasive pelvic reduction frame from April 2018 to April 2020 were retrospectively analyzed, including 21 males and 9 females, aged from 19 to 57 (39.40±9.85) years old. The patient's pelvic CT DICOM data were imported into Mimics software to reconstruct the virtual fracture model. Virtual reduction and nail placement were carried out on the fracture model, and then simulated fluoroscopy was carried out to record the ideal fluoroscopy orientation and angle to guide the correct fluoroscopy during operation. The operation time, fluoroscopy times and intraoperative blood loss were recorded. The quality of fracture reduction was evaluated by Matta image score standard, and the postoperative function was evaluated by Majeed function score standard.

RESULTS

All 30 patients achieved closed reduction and percutaneous screw fixation. According to Matta score, the excellent and good rate of fracture reduction was 93.3%(28/30). A total of 67 channel screws were inserted, and the excellent and good rate was 98.5%(66/67). The operation time was (173.54±79.31) min, fluoroscopy time was (90.81±41.11) times, intraoperative blood loss was (81.21±43.97) ml. All incisions healed at one stage without broken nails or re-displacement of fractures. All patients were followed up for 12 months. At the final follow-up, Majeed function score was 73 to 94(85.66±5.33) scores.

CONCLUSION

Computer virtual technology combined with pelvic reduction frame could rapidly, accurately and safely reduce and fix unstable pelvic fractures. Computer virtualization could help surgeons to recognition and understanding pelvic fractures, pelvic reduction frame could improve the surgeon's ability to manage complex and unstable pelvic injuries.
