Abstract
OBJECTIVE: To review the history, current situation, and progress of augmentation plate (AP) for femoral shaft nonunion after intramedullary nail fixation. METHODS: The results of the clinical studies about the AP in treatment of femoral shaft nonunion after intramedullary nail fixation in recent years were widely reviewed and analyzed. RESULTS: The AP has been successfully applied to femoral shaft nonunion after intramedullary nail fixation since 1997. According to breakage of the previous nailing, AP is divided into two categories: AP with retaining the previous intramedullary nail and AP with exchanging intramedullary nail. AP is not only suitable for simple nonunion, but also for complex nonunion with severe deformity. Compared with exchanging intramedullary nail, lateral plate, and dual plate, AP has less surgical trauma, shorter healing time, higher healing rate, and faster returning to society. However, there are still some problems with the revision method, including difficulty in bicortical screw fixation, lack of anatomic plate suitable for femoral shaft nonunion, and lack of postoperative function and quality of life assessment. CONCLUSION: Compared with other revision methods, AP could achieve higher fracture healing rate and better clinical prognosis for patients with femoral shaft nonunion. However, whether patients benefit from AP in terms of function and quality of life remain uncertain. Furthermore, high-quality randomized controlled clinical studies are needed to further confirm that AP are superior to the other revision fixations.
