Risk Factors for Nonunion After Lateral Locked Plating of Periprosthetic Distal Femur Fractures
In this study of 218 patients undergoing lateral locked plating for a periprosthetic distal femur fracture, 9 out of 10 patients did not undergo reoperation to promote fracture union. Factors associated with reoperation included increased BMI, the presence of multifragmentary metaphyseal comminution, and varus malalignment with a lateral distal femoral angle of ≥84 degrees. The use of titanium plates was associated with decreased odds of reoperation although this finding should be interpreted in the context of varying plate designs and configurations. These results may help delineate indications for the selection of specific fixation constructs when treating periprosthetic distal femur fractures.
