Abstract

Abstract:

BACKGROUND: Transpedicular positioning of the sacroiliac joint guider is more effective than traditional operation in the treatment of posterior pelvic annulus fracture. It not only shortens the operation time and intraoperative fluoroscopy, but also improves the surgical safety.

OBJECTIVE: To evaluate the clinical feasibility of the transpedicular positioning of the sacroiliac screw guider, and to provide basic data for clinical application.

METHODS: In five cases of human cadaver pelvis (10 sacroiliac joints), 10 sacroiliac screws were implanted into S₁through sacroiliac joint under the guidance of the self-designed sacroiliac screw guider. The safety of placement was confirmed by fluoroscopy.

RESULTS AND CONCLUSION: (1) All the sacroiliac screws were implanted accurately, and none of them broke through the anterior cortical bone or entered the spinal canal. (2) The pedicle screws were used to guide the sacroiliac joint guidance with stable screw placement, and satisfactory efficacy. (3) These results indicate that transpedicular localization of sacroiliac screws in the treatment of posterior pelvic ring fractures shows high accuracy, good fixation effect, and can decrease operation risk, significantly reduce intraoperative fluoroscopy, reduce the requirements for the operator, and shorten the learning curve, which can be widely used in clinical practice.
