Abstract

Background: In this study, we reviewed the results of conventional osteosynthesis combined with strut onlay allografts and autogenous bone grafts as the treatment for nonunion of the femur. Methods: We conducted a retrospective study of 18 patients with nonunion of the femur treated with internal fixation (eight 95° fixed-angled blade plates, 7 intramedullary nails, 2 dynamic hip compression plates and screws, and 1 condylar buttress plate) and autogenous bone grafts and cortical strut allografts. There were 1.8 operations on average before surgery. The average time from the initial treatment of the fracture or osteotomy to surgery was 32.5 months. The average follow-up was 32.2 months. Results: All 18 nonunions had healed by the time of follow-up. Positive intraoperative cultures (Staphylococcus epidermidis) in 2 patients were resolved by parenteral antibiotics with no additional treatment. Removal of implants was required in 5 patients because of screw irritation or bony union. One concomitant quadricepsplasty as well as 2 excisions of a protruding graft were required because of restricted knee motion or impingement. Conclusions: For difficult nonunions of the femur in the current study, strict adherence to the principles of the treatment of nonunion and the addition of strut allografts to enhance stability and repair potential proved to be a good alternative.
