Objectives: This study aims to evaluate the success of plate augmentation over a retained intramedullary nail (IMN) against exchange nailing performed with autologous bone grafting in oligotrophic and atrophic pseudoarthrosis of the femoral shaft. Patients and methods: Between May 2005 and October 2020, a total of 42 of 56 patients (28 males, 14 females; mean age: 47.3±17.2 years; range, 19 to 84 years) with aseptic atrophic or oligotrophic femoral nonunion were retrospectively analyzed. The patients, 20 were operated with plate over a retained IMN, and the rest (n=22) by exchange nailing. Data including demographic and clinical characteristics of the patients, treatment success, duration of surgery, blood loss during surgery, infection rates, length of hospital stay, time to bridging of the nonunion site, and time to obliteration of the fracture line (solid union) were recorded. Results: The mean follow-up was 23.8±20.4 (range, 12 to 96) months in the plate over an IMN group and 34.7±27.4 (range, 12 to 90) months in the exchange nailing group. At the final follow-up, solid union occurred in all of the patients in the plate augmentation over a retained IMN group, and 21 of 22 (95.45%) patients in the exchange nailing group. Blood loss during surgery was significantly less in the plate augmentation over IMN group (p=0.027). There was no statistically significant difference in the other variables between the two groups (p>0.05). Conclusion: Our study results demonstrate that plate over a retained IMN is effective as exchange nailing in the surgical treatment of oligotrophic and atrophic pseudoarthrosis of the femoral shaft. However, it can be speculated that plate application over IMN is more advantageous in terms of blood loss during surgery.
