Functional and radiological outcomes in three-dimensional guided navigation percutaneous screw fixation of displaced pelvi-acetabular fractures: A retrospective review

Background The use of three-dimensional (3D) navigation percutaneous screw fixation has been reported in non-displaced or minimally displaced pelvi-acetabular fractures. For carefully selected displaced acetabular fractures, 3D navigation technique can be applied, which traditionally required open approach. Methods From 2018 to 2024, 29 patients underwent 3D-guided navigation percutaneous screw fixation. Various reduction techniques were used. Functional and radiological outcomes were assessed. Results Twenty-four patients were followed up after definitive fixation with average duration of 33 months. All patients showed fracture union with average union time of 7.3 months. The mean Merle d’Aubigne and Harris Hip scores were 14.3 and 86.2 points, respectively. Younger age, lower injury severity score and earlier definitive operation correlated with improved functional outcome. Percutaneous fixation demonstrates advantages in terms of operative duration, blood loss, length of stay. Conclusion This surgical technique safely and effectively manages pelvi-acetabular fractures, resulting in pain relief, early mobilization and favourable patient outcomes.
