摘要先天性桡骨头脱位（congenital radial head dislocation, CRHD）是肘关节最常见的先天畸形。其临床特点早期不易发现，病理改变与创伤性脱位相似，易漏诊误诊。患儿常常合并其他畸形，尤其与各种综合征相关。其诊断方式以X线为主，CT、MRI、关节造影等方式可以提高诊断的正确率。治疗方式包括桡骨头切开复位、尺骨延长、桡骨短缩、环状韧带重建、桡骨头切除等。目前国内尚无系统性总结CRHD的研究，仅有少数病例报告报道。本研究通过复习国内外相关文献，对CRHD的相关研究做一综述，以期为临床提供指导。

abstractsCongenital radial head dislocation (CRHD) is the most common congenital deformity affecting elbow joint. Early detection is challenging, contributing to a high rate of missed diagnoses. Its pathological changes are similar to traumatic radial head dislocation, resulting in misdiagnosis in clinical practice. CRHD patients are often associated with other malformations, especially various syndromes. X-ray is the primary diagnostic method, and computed tomography (CT), magnetic resonance imaging (MRI) and arthrography can improve the accuracy of diagnosis. The treatment methods include open reduction of radial head, lengthening of ulna, shortening of radius, reconstruction of annular ligament, resection of radial head, etc. At present, there are only a few cases of CRHD reported in China, and a systematic review of CRHD is scant. In this study, by reviewing the relevant literatures at home and abroad, the related research on CRHD was reviewed in order to provide clinical guidance.
