Boldface indicates statistical significance. P value calculated using a stepwise, multivariate Poisson regression with robust error variance evaluating age ≥ 60 years, male gender, interposed/incarcerated fragment, multiple fragments, ≥ 25% articular involvement, displacement ≥5 mm, and percutaneous fixation as potential risk factors.
