A retrospective review of 24 patients with congenital radial head dislocation and three patients with congenital elbow dysplasias was performed. Eight patients had only congenital radial head dislocations and no other anomalies. In these eight patients, a noted limitation of elbow and forearm motion was greatest in those with anterior dislocations. Limitation of wrist motion also was noted in all affected extremities. Unilateral congenital radial head dislocation as well as progressive subluxation to dislocation were documented. There was no increased loss of motion as growth occurred. Significant pain was noted only in adults. Radial head excision after age 15 relieved pain and improved cosmesis but failed to significantly affect motion. Excision performed prior to this age showed regrowth of the proximal radius. A finding of increased ulnar length in relation to the radius in wrist roentgenograms of affected extremities was a significant diagnostic sign.
对24例先天性桡骨头脱位患者和3例先天性肘部发育不良患者进行了回顾性研究。8例患者仅有先天性桡骨头脱位，无其他异常。在这8例患者中，肘部和前臂活动受限最明显的是前脱位患者。所有受累肢体均存在腕关节活动受限。记录了单侧先天性桡骨头脱位以及逐渐半脱位至脱位的情况。随着生长发育，活动度并未进一步丧失。仅在成年患者中出现明显疼痛。15岁以后进行桡骨头切除术可缓解疼痛并改善外观，但对活动度无显著影响。在此年龄之前进行切除术，可见桡骨近端再生。在受累肢体的腕部X线片上发现尺骨相对于桡骨长度增加是一个重要的诊断体征。
