There is limited literature reporting on sacral insufficiency fractures as a cause of lumbopelvic instability. We describe the presentation, treatment, and clinical outcome with a 2-year follow-up of a woman who sustained a low-energy spinopelvic dissociation diagnosed with magnetic resonance imaging. There was significant delayed displacement, and the patient was treated surgically with percutaneous iliosacral and trans-sacral screws.
U-type sacral insufficiency fractures may be subtle on advanced imaging and must be followed closely if nonoperative treatment is chosen. These patients may require surgical intervention. Iliosacral screws and lumbopelvic fixation are treatment options, each with advantages and disadvantages.
关于骶骨不足性骨折作为腰骶部不稳定的原因的文献报道有限。我们描述了一位女性的表现、治疗和临床结果，该女性因低能量性脊柱骨盆分离而接受磁共振成像诊断，其发生了明显的延迟移位，患者接受了经皮髂骨和经骶骨螺钉的手术治疗。
U 型骶骨不足性骨折在高级影像学上可能不明显，如果选择非手术治疗，必须密切随访。这些患者可能需要手术干预。髂骨螺钉和腰骶部固定是治疗选择，各有优缺点。
