为了分析儿童肱骨内上髁骨折保守和手术治疗的疗效,为临床治疗提供参考.随访了7～14岁肱骨内上髁骨折32例.随访时间3～6年.平均4.5年.21例保守治疗,11例手术治疗.X线检查发现保守治疗组有5种肱骨内上髁形态的改变:假关节、尺侧沟、双骨骺、过度发育及高或低位内上髁.这些畸形对肘关节的功能影响不大,但14例非骨性愈合中4例有活动后肘部不适,其中2例运动成绩受到影响,3例肘外翻不稳定,2例有尺神经症状,1例Tinel征阳性.手术组无上述并发症.因此,对骨折闭合复位后移位大于5mm、并肘外翻不稳定者应手术治疗.%Thrity-two children aged 7-14 years with fracture of humeral medical epicondyle were reviewed.All were followed up of 3 to 6 yrs (4.5 yrs on an average).21 cases were treated conservatively and 11 surgically.There were 5 types of deformities in the conservative group on X-ray features concluding:pseudarthrosis,ulnar sulcus,double epiphysis,hyperplasia and high or low position of epiphysis.None of the deformities impaired the elbow function,but pseudarthrosis developed in 14/21 cases.Of them,4 had elbow aches (2 had to abandon athletics),3 had abducent elbow,2 mild disorder of ulnar nerve,and 1 Tinel sign.However no such complications were found in the surgical group.The results suggest that valgus instability and displacement of fracture more than 5mm after close reduction indicate an open reduction should be performed.
