Risk factors and treatment methods of nonunion after intramedullary nailing of subtrochanteric femoral fractures:a review
The surgical reduction and fixation of subtrochanteric femoral fractures are challenging due to its particular anatomical and biomechanical characteristics.Intramedullary nailing is the golden standard for its treatment,but postoperative bone nonunion is a common complication,resulting in limb pain and decreased mobility,which requires a second operation and greatly affects the patients'life quality.At present,there are many studies on the risk factors of bone nonunion after intramedullary nail fixation,but the risk factors with strong correlation remain unclear and the subsequent treatment plans are diverse,without consensus.Further identification of risk factors can help to select treatment plans.To this end,the authors reviewed the research progress in the risk factors and treatment methods of bone nonunion after intramedullary nailing of subtrochanteric femoral fractures to provide references for its clinical treatment.
