为了积极有效地治疗儿童肘部损伤后发生的肘外翻畸形，对肘外翻发生的原因、预防和治疗进行讨论。本组共２６例，肘部损伤时年龄２～１４岁（平均７．５岁）。儿童肘部损伤为肱骨外髁骨析１４例，肱骨外髁骨折合并桡骨小头脱位１例，肱骨髁上骨折８例，肱骨内髁骨折１例，桡骨小头脱位２例。肘关节提携角２０～４５（平均２８）。合并创伤性尺神经炎１９例，创伤性关节炎７例。１９例合并创伤性尺神经炎作神经松解前移术，平均随访６．６年，优良率８８．２％。５例肘外翻作肪骨髁上截骨术，平均随访９．４年，肘关节外观及功能满意。结论：延误诊治、复位固定不良是儿童肘部损伤后发生肘外翻的原因。早期诊断、及时准确复位和确切固定是减少肘外翻发生的重要措施，对有移位的骨折的反复手法复位可加重骨骺损伤。８岁以上严重肘外翻畸形可作肱骨髁上截骨术矫正，合并创伤性尺神经炎应早期作尺神经松解前移术。
In order to actively and effectively treat elbow valgus deformity after elbow injury in children, the causes, prevention and treatment of elbow valgus are discussed. The group of 26 cases, elbow injury age 2 to 14 years (mean 7.5 years). Elbow injury in children was 14 cases of lateral condyle of humerus, 1 case of humeral lateral condyle fracture combined with radial head dislocation, 8 cases of supracondylar fracture of humerus, 1 case of humeral medial condyle fracture and 2 cases of radial head dislocation. Elbow lifting angle 20 ~ 45 (average 28). 19 cases of traumatic ulnar inflammation combined with traumatic arthritis in 7 cases. Twenty-nine patients with traumatic ulnar neuritis were treated with neurolysis and an average of 6.6 years follow-up. The excellent and good rate was 88.2%. 5 cases of elbow valgus osteotomy for supracondylar osteotomy, the average follow-up 9.4 years, the appearance and function of the elbow is satisfactory. Conclusion: Delayed diagnosis and treatment and resetting poor fixation are the causes of elbow valgus after elbow injury in children. Early diagnosis, timely and accurate reduction and exact fixation is an important measure to reduce the occurrence of elbow valgus. The repeated manipulation of displaced fractures can increase the epiphyseal injury. Elbow valgus deformity over the age of 8 can be used for supracondylar supracondylar osteotomy correction, traumatic ulnar neuritis should be early for the ulnar nerve lysis.
