Objectives:
This study aims to investigate if pelvic mapping is applicable in iliosacral screw fixation to determine screw entry point and screw trajectory.
Patients And Methods:
Clinical files and images of 16 patients (10 males, 6 females; mean age 35 years; range, 20 to 57 years) who underwent iliosacral screw fixation due to sacroiliac joint injury and sacrum fracture were retrospectively reviewed. Pelvic mapping was performed using preoperative tomography images of the patients and appropriate screw entry point and trajectory were determined. Postoperative computed tomography scans of all patients were obtained and these were used to evaluate the accuracy of the screw position.
Results:
No intraoperative complications occurred. The entry points and trajectory of the screws were compatible for all patients pre- and postoperatively.
Conclusion:
Mapping of the pelvis is a method that can be used for preoperative planning of iliosacral screwing.
