Abstract: ［Abstract］ Objective To investigate the effect of the treatment of the humeral lateral condylefracture in children under Elbow arthroscopy. Methods Sixty?four cases of the humeral lateral condyle fracture were randomly divided into open reduction group and arthroscopy group，each group of 32 cases. Results All the 64 patients were followed up for 12?24 months postoperatively，with average of 17.15±5.12 months. The amount of bleeding in the arthroscopy group and the open reduction group was 40.5±8.5 ml and 110.5 ± 15.5 ml，the length of incision was 0.95 ± 0.30 cm and 6.95 ± 1.50 cm，and the visual analogue pain score （VAS） was 3.85 ± 1.35 and 7.85 ± 2.05 respectively on the third day after the operation，and the differences were statistically significant. According to Mayo score，the total fine rate was 84.4% in the open reduction group and 96.9% in the arthroscopy group，and the difference between the two groups was statistically significant. In the open reduction group，there were 3 cases of elbow joint varus deformity，5 cases of nail path infection. However there were one case of elbow joint varus deformity in arthroscopy group. There was a statistically significant difference in postoperative complications between the two groups. Conclusion Arthroscopic reduction and percutaneous internal fixation for the treatment of humeral lateral condyle fractures in children has advantages of less trauma and fewer complications.
