Outcomes of Distal Femur Nonunions Treated with a Combined Nail/Plate Construct and Autogenous Bone Grafting.

Abstract

SummaryIn this study, we sought to retrospectively evaluate union and infection rates after treatment of distal femur nonunions using a combined nail/plate construct with autogenous bone grafting. 10 patients treated at a Level I Trauma Center for nonunion of a femoral fracture using a combined nail/plate construct from 2004 to 2014 were included in the study. Union rate and postoperative infection rate were recorded.10 patients underwent treatment for nonunion of the distal femur. Mean interval from index surgery to nonunion repair was 12 months (range 4-36 months). All 10 patients achieved union at an average of 3.9 months (range 2.3-8 months) after initial nonunion repair. Treatment of distal femur nonunions with a combined nail/plate construct and autogenous bone grafting results in a high rate of union with a low complication rate. This technique combines two straightforward procedures familiar to orthopaedic trauma surgeons and offers distinct advantages including: availability of adequate bone graft volume, absence of donor site morbidity, and increased construct stability that may permit earlier weight-bearing.
