Abstract
This article reviews the research progress of S1-S3 sacroiliac screw fixation for posterior pelvic ring injury, reports one case of S1-S3 sacroiliac screws fixation for posterior pelvic ring injury with S1 sacral dysmorphism. The clinical data, preoperative preparation, surgical procedure, and postoperative outcomes of a patient with pelvic fracture who underwent treatment of 3 sacroiliac screws(S1-S3) fixation on August 07, 2023, at Weifang City People’s Hospital were summarized. The patient successfully underwent treatment of 3 sacroiliac screws(S1-S3) fixation. Postoperative X-rays and CT scans confirmed that all screws were in good position and located in the bone corridors. For patients with S1 sacral dysmorphism, the traditional S1 corridor is often difficult to place nails, while the S3 is an alternative corridor to easily place sacroiliac screw.
