ABSTRACT
Objective:
To evaluate the clinical efficacy of percutaneous channel screwing assisted by the robot navigation positioning system combined with pelvic unlocking reduction frame for pelvic fractures.Methods:
A retrospective analysis was conducted of the 12 patients with pelvic fracture who had been admitted to Department of Orthopaedics, The First Affiliated Hospital to Anhui Medical University from January to October 2018. They were 7 men and 5 women with an average age of 42.3 years (from 25 to 62 years). The time from injury to operation averaged 5.1 days (from 2 to 10 days). There were 2 cases of type B1, 5 ones of type B2 and 5 ones of type C1 according to the Tile classification. After closed reduction using the pelvic unlocking reduction frame, the orthopedics robot navigation positioning system was used to guide the placement of percutaneous screws. The posterior rings were fixated with sacroiliac screws, and the anterior rings with pubis screws, pubic symphysis screws or external fixation. The placement time for each screw, fluoroscopy frequency, reduction quality, fracture union time, function of the affected hip and complications at the final follow-up were recorded.Results:
A total of 25 percutaneous screws were inserted in the 12 patients with a mean fluoroscopic frequency of 4.7 times (from 3 to 8 times) and a mean placement time of 14.9 min (from 12 to 20 min). According to the Matta rating system, the fracture reduction was rated as excellent in 7 cases, as good in 4 and as fair in one. The average follow-up time was 11.3 months (from 6 to 16 months). All fractures healed after an average period of 11.8 weeks (from 10 to 14 weeks). By the Majeed scoring, the pelvic function at the final follow-up was excellent in 8 cases and good in 4. The follow-ups observed no infection, nerve injury, deep vein thrombosis, heterotopic ossification, implant looseningor traumatic arthritis in these patients.Conclusion:
Percutaneous channel screwing assisted by the robot navigation positioning system combined with pelvic unlocking reduction frame can reduce operative time and risks and lead to minimal invasion for pelvic fractures.
