Casting, elastic intramedullary nailing or external fixation in pediatric tibial shaft fractures: which is the most appropriate treatment? A multicenter study.

The main objective of this study was to retrospectively evaluate and compare the outcomes and complications of displaced closed tibial fractures in children treated by CRC (closed reduction and casting), elastic stable intramedullary nailing (ESIN) or external fixation (EF). One hundred twenty-three consecutive children were treated for displaced closed tibia shaft fracture from July 2014 and January 2020 at two different institutions. Seventy-five of them met the inclusion criteria and were included in the study: 30 (40%) patients were treated with CRC, 33 (44%) with ESIN, and 12 with EF (16%). All clinical and radiographic outcomes and complications were registered and compared. The three groups did not differ with regard to gender, affected side, fracture site and associated fibula fracture. The age at the time of treatment in the CRC group was statistically lower than in ESIN and EF groups (8.43 ± 3.52 years vs. 10.39 ± 2.56 years vs. 11.08 ± 3.55 years, respectively). Immobilization time and time to partial and total weight bearing were significantly reduced in ESIN and EF groups compared to CRC group ( P  < 0.05). Overall, no statistically significant differences were found between the three groups regarding complication rate and clinical and radiographic outcomes between the three groups. However, in CRC group, 3 patients (10%) had secondary fracture displacement and underwent ESIN. Surgical treatment is not contraindicated in children with displaced tibia shaft fractures. EF and ESIN provide earlier mobilization and weight-bearing recovery than CRC. However, apart from that, nonoperative treatment was as efficacious as surgical treatment.
