Abstract
OBJECTIVE: To investigate the application of modified elastic intramedullary nail and the outcomes between modified elastic stable intramedullary nailing and traditional elastic stable intramedullary nailing in children with distal tibial metaphyseal junction fracture. METHODS: A retrospective study was conducted. From January 2018 to January 2021, a total of 36 children with distal tibial metaphyseal junction fracture were treated in our hospital. All of them were treated with closed reduction and elastic stable intramedullary nailing internal fixation. A total of 18 children were treated by modified elastic stable intramedullary nailing and 18 children were treated by traditional elastic stable intramedullary nailing. Postoperative imaging, clinical efficacy, and complications were analyzed. RESULTS: The mean follow-up time was 20 (15-36) months in modified group and 22 (16-33) months in traditional group. There were no complications such as infection, loss of reduction, and unequal length of lower limbs in modified group while loss of reduction occurred in two cases in traditional group. In these two cases of loss of reduction, we preformed manual reduction and replacement of long leg casts, and there was no loss of reduction, and the patient achieved a good prognosis. In the last follow-up, American Orthopaedic Foot & Ankle Society score was used. In modified group, excellent outcome achieved in 17 cases, good outcome achieved in 1 case, and satisfactory therapeutic effect was achieved. In traditional elastic stable intramedullary nailing group, excellent outcome achieved in 14 cases, and good outcome achieved in 4 cases. There was no statistical difference in the scores between the two groups. CONCLUSION: It was concluded that modified elastic stable intramedullary nailing fixation is a safe and effective treatment.
