Risk Factors for Delayed Union of Tibial Shaft Fractures Treated with Unreamed Interlocking Intramedullary Nails Internal Fixation

Abstract：Objective? To investigate the risk factors of delayed union of tibial shaft fractures treated with unreamed interlocking intramedullary nails internal fixation. Methods? A total of 265 cases of tibial shaft fractures admitted to our hospital from January 2012 to December 2018 were retrospectively collected. According to the existence of delayed union after operation, all patients werewere divided into delayed group (N=82 cases) and control group (N=183 cases). The baseline data and treatment of the two groups were compared, and the risk factors of delayed healing were discussed. Results? Univariate logistic regression analysis showed that age, BMI, early activity, internal fixation quality, instability of fracture end and functional exercise were related to delayed union of fracture (P<0.05). Multivariate logistic regression analysis showed thatearly activity, internal fixation quality, instability of fracture end and functional exercise were still related to delayed union of fracture after age and BMI were excluded (P<0.05). Conclusion? For patients with tibial shaft fracture treated with unreamed interlocking intramedullary nail internal fixation, if there are early activities, poor internal fixation, unstable fracture end and no functional exercise after operation, the occurrence of delayed union should be vigilant.
