Abstract
PURPOSE: To analyze clinical, radiographic and patient-reported outcomes of distal metaphyseal femoral nonunions treated with fixed-angle plates and screws. METHODS: All patients presenting with a distal metaphyseal femoral fracture nonunion repaired with fixed-angle plating from one urban level 1 trauma center and an orthopedic specialty hospital were identified. Baseline demographic, injury information, and outcomes (healing rates, Short Musculoskeletal Function Assessment, range of motion, and post-operative pain levels) at 12 months following nonunion repair were collected. Outcomes were evaluated between patients fixed with a blade plate and with a locking plate. RESULTS: Of these 31 patients, 27 (87.1%) healed after their index nonunion surgery, 2 (6.5%) healed after one reoperation, 1 (3.2%) healed after 2 reoperations, and 1 (3.2%) had a persistent nonunion but did not want further treatment. At one-year follow-up, the group demonstrated a significant improvement in functional recovery with a mean difference of 14.5 points (p = 0.007) when compared to status before fixed-angle fixation of the nonunion. There was also a significant change in patient-reported pain levels using the VAS scale with a mean difference of 2.0 points (p = 0.009). At one-year follow-up, 11 (39.3%) had full knee range of motion (0-130), 11 (39.3%) had flexion greater than 90 and less than 120°, and 6 (21.4%) had range of motion less than 90°. CONCLUSION: Patients who undergo fixed angle plating and autogenous bone grafting for distal femoral metapyseal nonunions demonstrate improved functional outcomes and VAS pain score at one year follow up.
