Original Paper



Navigation assisted minimally invasive percutaneous screw fixation (MIS) for pelvi-acetabular fracture was recently advocated.


We report 38 consecutive cases of pelvi-acetabular fractures treated with 3D navigation-guided MIS from 2015 to 2016. Ohe hundred and forty-three screws were inserted (59 sacroiliac, 45 retrograde anterior column, 34 supra-acetabular, three antegrade posterior-column and two subcristal). Navigation planning was mainly performed pre-operatively.


The mean operative blood loss and time was 179 ml and 141 mins, respectively. The distance (deviation) between the planned and executed screw entry and tip measured by the navigation computer were 1.91 and 1.94 mm, respectively. There were no immediate or early surgical complications. Patients were followed for at least 6 month; 79% had fracture healing at 4.3 months on average, and 53% walked unaided by the six month follow-up. The average visual analogue scale for pain was 2.69.


We believe 3D navigation-guided MIS is a safe and effective surgical alternative in most pelvi-acetabular fractures.
