ABSTRACT
OBJECTIVE@#To explore the operative method and clinical effect of lateral mini plate and Kirschner wire in the treatment of distal humeral metaphysis junction fracture in children.@*METHODS@#From January 2015 to December 2018, 21 cases of distal humeral diaphyseal metaphyseal junction fracture were analyzed retrospectively, including 12 males and 9 females, aged 2 to 10 years with an average age of 4.5 years, and the time from injury to operation was 6 hours to 7 days. The imaging data showed that the fracture line was located at the junction of the distal humerus and metaphysis. There were 10 oblique fractures, 8 transverse fractures and 3 comminuted fractures. The operation methods were open reduction, lateral mini plate and Kirschner wire assisted internal fixation, and the improved Flynn elbow joint scoring standard was used to evaluate the clinical effect.@*RESULTS@#All the 21 children were followed up for 8 to 24 months, with an average of 13 months. The healing time was 6 to 8 weeks, with an average of 7.2 weeks. There were no complications such as fracture displacement, cubitus varus and ulnar nerve injury. According to the improved Flynn elbow joint scoring standard, 19 cases were excellent and 2 cases were good.@*CONCLUSION@#The treatment of distal humeral metaphyseal junction fracture in children is different from that of supracondylar fracture of humerus.
