Association of Body Mass Index With the Pattern of Surgically Treated Ankle Fractures Using Two Different Classification Systems

Abstract The present retrospective cohort study assessed the association of body mass index (BMI) with the pattern of ankle fractures using 2 classifications systems. Of the 1011 consecutive patients who underwent surgery for ankle fractures in 2 hospitals from January 2009 to December 2011, 837 had...

Description
Summary:Abstract The present retrospective cohort study assessed the association of body mass index (BMI) with the pattern of ankle fractures using 2 classifications systems. Of the 1011 consecutive patients who underwent surgery for ankle fractures in 2 hospitals from January 2009 to December 2011, 837 had a classifiable fracture according to 1 of 2 classification systems and complete information available for covariates. The association of BMI, adjusted for age, sex, corticosteroid use, diabetes, and smoking status with having a more proximal fibula fracture (Weber class A to C) and an increasing number of malleoli involved (uni-, bi-, or trimalleolar) was assessed using multivariable ordered logistic regression analysis. The mean age of the patients was 50.9 ± 16.9 years, and 461 (55%) were female. On multivariable analysis, BMI and male sex were associated with having a more proximal fibula fracture using the Weber classification, with an odds ratio (OR) of 1.07 (95% confidence interval [CI] 1.04 to 1.11; p
