Surgical Outcomes of Internal Fixation Using Multiple Screws in Femoral Neck Fractures with Valgus Impaction: When Should We Consider Hip Arthroplasty? A Retrospective, Multicenter Study

We analyzed the surgical outcomes at two institutions after internal fixation using multiple screws in femoral neck fractures with valgus impaction to determine independent predictors and their cut-off values for nonunion and reoperation. Between January 2006 and December 2016, 104 femoral neck frac...

Description
Summary:We analyzed the surgical outcomes at two institutions after internal fixation using multiple screws in femoral neck fractures with valgus impaction to determine independent predictors and their cut-off values for nonunion and reoperation. Between January 2006 and December 2016, 104 femoral neck fractures with valgus impaction that underwent internal fixation using multiple screws from two institutions were enrolled. The multiple logistic regression model and receiver operating characteristics analysis were used to determine the independent predictors and cut-off values for nonunion and reoperation. There were 20 reoperations (19.2%) due to 11 nonunions (10.6%) and nine cases of femoral head osteonecrosis (8.7%). Multiple logistic regression analysis revealed that independent predictors of nonunion and reoperation were age and posterior tilt angle (
