应用时关节外侧小切口切开复位交叉克氏钟内固定治疗小儿肱骨踝上骨折８６例，获随访６７例，优良率８８％；发生肘内翻１１例，发病率１６．４％．认为肢骨踝上骨折后肘内出形成有２个主要原因：（１）骨折远端骨片内旋尺偏移位复位不良；（２）骨折复位后因固定使关节周围发生粘连，削弱了该处生物力学的作用，使该处承受较大的机械力学作用，提出了小儿肱骨髁上骨折切开复位克氏针内固定的适应证及其优点。
Application of lateral small incision and open reduction and internal fixation with Kirschner wire fixation in 86 cases of pediatric humeral ankle fractures, 67 cases were followed up, the excellent and good rate was 88%; elbow varus occurred in 11 cases, the incidence rate was 16.4%. It is believed that there are 2 main reasons for the formation of elbow in the fracture of the extremity and ankle: (1) the displacement of the internal rotation of the distal fragment of the fracture is poorly reset; (2) the adhesions around the joint are weakened due to the fixation after fracture reduction The role of biomechanics here, so that the Department to bear the greater role of mechanical, put forward pediatric supracondylar humerus fracture replacement Kirschner wire indications and their advantages.
