Lateral compression type1 (LC-1) pelvic fractures represent a wide spectrum of heterogeneous injuries. These include both stable and unstable patterns; however, determining whether a LC-1 fracture is stable or unstable is a challenge, and the method used to evaluate fracture stability is complicated.
We prospectively collected and analyzed data from 22 patients with LC-1 pelvic fractures, who underwent ultrasonography and a pelvic compression and separation test, in order to evaluate the role of ultrasonography in determining fracture stability and assist decision-making for treatment strategy.
Twenty-two patients (15 men and 7 women) were included in the study. Following an ultrasound examination, 10 patients were classified into the stable group and 12 into the unstable group. In total, 13 patients received conservative treatment and 9 underwent surgery. At follow-up, there were no differences in fracture healing times or fracture-related complications between the two groups. The Majeed score was comparable between the two groups and most patients recovered well. There was a moderate degree of consistency in Kappa values (Kappa = 0.571, P = 0.01) between the classification of stability and the final treatment received. In addition, the sensitivity of ultrasonography was 66.67% and the specificity was 76.92%.
In conclusion, ultrasonography is a useful tool for diagnosing the stability of LC-1 pelvic fractures and assists the determination of treatment strategy. Left-right mobility ≥ 0.3 cm may be used as the criterion for determining instability.

LC-1 型骨盆侧方挤压伤（LC-1 pelvic fractures）表现出广泛的异质性损伤。这些损伤包括稳定型和不稳定型；然而，确定 LC-1 骨折是否稳定是一项挑战，评估骨折稳定性的方法也很复杂。
我们前瞻性地收集并分析了 22 例 LC-1 型骨盆骨折患者的数据，这些患者均接受了超声检查和骨盆压缩分离试验，以评估超声在确定骨折稳定性中的作用，并辅助制定治疗策略。
共纳入 22 例患者（15 例男性，7 例女性）。经超声检查后，10 例患者被分为稳定组，12 例患者分为不稳定组。共有 13 例患者接受了保守治疗，9 例患者接受了手术治疗。随访时，两组患者的骨折愈合时间和骨折相关并发症无差异。两组患者的 Majeed 评分相当，大多数患者恢复良好。Kappa 值（Kappa = 0.571，P = 0.01）具有中度一致性，表明稳定性分类与最终治疗之间具有一定的相关性。此外，超声检查的灵敏度为 66.67%，特异性为 76.92%。
总之，超声检查是诊断 LC-1 型骨盆骨折稳定性的一种有用工具，并有助于确定治疗策略。左右活动度≥0.3cm 可作为确定不稳定的标准。
