Early complications of preoperative external traction fixation in the staged treatment of tibial fractures: A series of 402 cases

BACKGROUND: Different external skeletal fixators have been widely used in preoperative traction of high-energy tibial fractures prior to a definitive surgical treatment. However, the early complications associated with this staged treatment for traction and soft tissue injury recovery have rarely been discussed. AIM: To analyze the early complications associated with preoperative external traction fixation in the staged treatment of tibial fractures. METHODS: A total of 402 patients with high-energy tibial fractures treated using preoperative external traction fixation at a Level 1 trauma center from 2014 to 2018 were enrolled in this retrospective study. Data regarding the demographic information, Tscherne soft tissue injury, fracture site, entry point placement, and duration of traction were recorded. Procedure-related complications such as movement and sensation disorder, vessel injury, discharge, infection, loosening, and iatrogenic fractures were analyzed. RESULTS: The mean patient age was 42.5 (18-71) years, and the mean duration of traction was 7.5 (0-26) d. In total, 19 (4.7%) patients presented with procedure-related complications, including technique-associated complications in 6 patients and nursing-associated complications in 13. Differences in the incidence of complications with respect to sex, affected side, soft tissue injury classification, and fracture sites were not observed. However, the number of complications due to hammer insertion was significantly reduced than those due to drill insertions (2.9% vs 7.4%). CONCLUSION: We found a low incidence of early complications related to the fixation. Furthermore, the complications were not significantly associated with the severity of the soft tissue injury and fracture site. Although relatively rough and more likely to cause pain, the number of complications associated with hammer insertion was significantly smaller than that of complications associated with drill insertion.
