There are few reports on the treatment of pelvic posterior ring injury with Sacral 1 - Sacral 3(S1-S3)sacroiliac screw fixation. This article reports a case of pelvic posterior ring injury with S1 sacral dysmorphism treated with S1-S3 sacroiliac screw fixation and reviews the relevant research progress.
A 72-year-old man riding e-bike was struck by a car at a high speed and diagnosed with pelvic fracture. 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. Follow up pelvic Majeed score of 96 at 11th month after surgery.
Preoperative CT scans of this patient showed that S1 segment was a dysmorphic sacrum with narrow corridor while S2 and S3 segments were wide corridors. S1-S3 sacroiliac screw fixation can be attempted.
For patients with posterior pelvic ring injury with S1 sacral dysmorphism, S1-S3 sacroiliac screw fixation may be a better choice.
关于采用骶1-骶3（S1-S3）骶髂螺钉固定治疗骨盆后环损伤的报道较少。本文报告1例采用S1-S3骶髂螺钉固定治疗的伴有骶1发育异常的骨盆后环损伤病例，并回顾相关研究进展。
一名72岁骑电动自行车的男性被一辆汽车高速撞击，被诊断为骨盆骨折。该患者成功接受了3枚骶髂螺钉（S1-S3）固定治疗。术后X线和CT扫描证实所有螺钉位置良好，位于骨通道内。术后第11个月骨盆Majeed评分为96分。
该患者术前CT扫描显示，骶1节段为发育异常的骶骨，通道狭窄，而骶2和骶3节段通道较宽。可尝试采用S1-S3骶髂螺钉固定。
对于伴有骶1发育异常的骨盆后环损伤患者，S1-S3骶髂螺钉固定可能是一种较好的选择。
