[Comparison of three fixation methods for the treatment of tibial fractures in adolescents].
OBJECTIVE
To explore the fixation methods in treatment of tibial fracture in adolescents by comparing the results and complications of three fixation methods and to determine the factors related to those complications.


METHODS
From January 2007 to January 2012, 83 diaphyseal tibial fractures in 79 adolescents were treated with elastic stable intramedullary nail fixation, plate fixation, or external fixation respectively. There were 55 males and 24 females with an average age of 13.9 years (ranging from 11 to 17.6 years). Outcomes were compared in terms of the hospital stay,time to union, complications, and reoperation rates.


RESULTS
All patients were followed up for 15.8 months in average. The time to union was significant associated with the pattern of fixation, energy of the injury, multiple and open fracture. The time of bone union of external fixation group was longer than that of elastic stable intramedullary nail fixation and plate fixation groups. But complication rates of external fixation group were higher than that of elastic stable intramedullary nail fixation and plate fixation groups. Four patients were treated with elastic nail fixation underwent a reoperation (loss of reduction in 2 cases, delayed union and nonunion in each 1 case). Six patients were treated with external fixation required a reoperation (loss of reduction in 3 cases, malunion in 2 cases, and replacement of a pin canal infection in 1 case). Two fractures were treated with plate fixation required refixation following nonunion and malunion. A multivariate analysis with adjustment for baseline differences showed external fixation to be associated with a 7.56 times (95% confidence interval=3.74 to 29.87) greater risk of loss of reduction and (or) malunion than elastic stable intramedullary nail fixation. At the final follow-up,there were agreeable results among three groups and no significant differences among them in final therapeutic effect (P>0.05).


CONCLUSIONS
External fixation for treatment of tibial fracture in adolescents has the highest rate of complications than the other two fixation methods. Elastic stable intramedullary nail fixation can achieve the same effect of other fixed system and avoid most of the complications. Operation method choice depends on the experience of doctors and patients' basic situation and the fracture types.
