Abstract:
The principles for surgical treatment of femoral neck fracture are anatomical reduction, rigid fixation and reduction of iatrogenic tissue damage to maintain sufficient blood supply and reduce the risk of complications such as avascular necrosis of the femoral head. In the evolution of internal fixation structures for femoral neck fracture, a variety of new products have been developed, such as the neck-shaft angle stabilization structure represented by dynamic hip screw, the multi-screw structure represented by three cannulated screws, and the plate-screw structure represented by multi-screw structure combined with a locked plate. These internal fixation structures have their own advantages and disadvantages in terms of stability and reduced risk of complications. However, none of them can perfectly meet the requirements of all the surgical principles. Femoral neck system (FNS) was firstly applied in clinic practice in 2017 to further improve the internal fixation of femoral neck fracture. In recent years, its mechanical properties and clinical effects have been widely reported in an attempt to further improve the implantation of this internal fixation device. This article reviews the researches on the mechanical properties and clinical efficacy of FNS and the suggestions put forward by orthopedic surgeons to improve the implantation methods of FNS.
