RESUMO

<p><b>OBJECTIVE</b>To further investigate the risk factors of cubitus varus in humeral condylar fracture after conservative treatment in children through Logistic regression analysis, so as to guide the clinical treatment.</p><p><b>METHODS</b>Children with humeral condylar fracture who were treated by manipulative reduction and plaster fixation in our hospital from March 2008 to December 2014 were studied. The clinical data including age, gender, BMI, time from injury to reduction, direction of displacement, rotation displacement, fixed position, and epiphyseal injury were collected. First, preliminary screen the risk factors through univariate analysis of the above data, then determine the risk factors of cubitus varus through multivariate Logistic regression analysis of the significant factors from univariate analysis.</p><p><b>RESULTS</b>Univariate analysis showed that time from injury to reduction, direction of displacement, rotation displacement and epiphyseal injury were significantly correlated with the cubitus varus. Multivariate Logistic regression analysis showed that time from injury to reduction which was longer than 8 h [=0.017, OR=3.303(1.243-8.774)], ulnar displacement [=0.001,=11.951(2.895-49.335)], rotation displacement [=0.003, OR=4.190(1.643-10.685)]and epiphyseal injury [=0.000,=7.092(2.557-19.671)] were independent risk factors of cubitus varus.</p><p><b>CONCLUSIONS</b>Time from injury to reduction, ulnar displacement, rotation displacement and epiphyseal injury are independent risk factors of cubitus varus. So it need corresponding treatment according to different risk factors.</p>
