BACKGROUND
Patellar dislocations are common, but superior-lateral dislocation with vertical axis rotation is rare and challenging to reduce.
CASE PRESENTATION
A woman in her 20s presented with left knee pain and deformity after minor trauma. Traditional reduction attempts failed due to a vertical rotational component. Reduction was achieved using a technique involving hip flexion, a modified varus-valgus force, and knee extension.
CONCLUSION
Emergency clinicians must recognize complex patellar dislocations and consider early orthopedic consultation to minimize complications.
背景
髌骨脱位很常见，但伴有垂直轴旋转的上外侧脱位很少见且复位具有挑战性。
病例报告
一名20多岁的女性在轻微创伤后出现左膝疼痛和畸形。由于存在垂直旋转成分，传统的复位尝试失败。通过一种包括髋关节屈曲、改良的内翻-外翻力和膝关节伸展的技术实现了复位。
结论
急诊临床医生必须认识到复杂的髌骨脱位，并考虑早期进行骨科会诊以尽量减少并发症。
