Abstract:
Femoral head necrosis and fracture nonunion are common postoperative complications of femoral neck fracture. Currently, it is believed that the main causes of postoperative complications include impaired local blood supply after fracture, poor reduction quality, and inappropriate selection of internal fixation, etc. While the incidence of nonunion was significantly reduced after fracture internal fixation, the incidence of femoral head necrosis was not significantly reduced. The occurrence of complications makes it a difficult clinical decision to determine the surgical approach in the treatment of femoral neck fracture. The causes and scientific prevention and treatment strategies of postoperative complications of femoral neck fracture remain to be further studied and explored. From the perspective of leverage reconstruction balance theory and supporting stretch effect theory of proximal femoral fracture, the authors intended to analyze the causes of complications after internal fixation of femoral neck fracture and proposed scientific treatment options and an innovative internal fixation product — "dynamic compression anti-stretch nail", aiming to provide insights into effectively reducing the occurrence of postoperative complications after internal fixation of femoral neck fracture and improve its treatment strategy.
