Abstract
BACKGROUND
Unstable pelvic fractures, especially vertical shear fractures, require surgery for correct reduction, rigid fixation, and improved postoperative outcomes. Herein, we assess the effectiveness of our minimally invasive procedure for the management of unstable pelvic fractures.
HYPOTHESIS
We hypothesized that this procedure would be useful for the management of unstable pelvic fractures.
PATIENTS AND METHODS
This study included 28 patients with unstable pelvic fractures (vertical shear injuries; AO types C1-3) treated using minimally invasive surgery for spinopelvic fixation (MIS-SP) between 2014 and 2020 (mean follow-up time, 15 months). The MIS-SP requires four percutaneous pedicle screws and four iliac screw insertions. Subsequently, reduction and fixation are performed.
RESULTS
The mean preoperative displacement of the posterior pelvic elements in craniocaudal correction was 17.6 (range, 9.0-32.2) mm. The mean length of the craniocaudal reduction was 16.5 (8.1-30.1) mm, with a mean reduction rate of 93.5% (78%-100%). The mean length of the mediolateral reduction was 11.3 (3.9-19.6) mm, with a mean reduction rate of 87.3% (76%-100%).
DISCUSSION
Our novel reduction and fixation procedure is a powerful, minimally invasive option for the treatment of unstable pelvic ring fractures.
