Therapeutic strategies for internal fixation of femoral neck fractures based on leverage fulcrum reconstruction theory / 中华骨科杂志

ABSTRACT

The objective of internal fixation is to preserve the hip and to reduce and fix the fracture. By reviewing the classifications of femoral neck fracture and the current status of internal fixation, we found that the existing internal fixation technology development cannot effectively avoid the occurrence of its related complications such as femoral neck shortening, nail withdrawal, screw removal, internal fixation fracture and so on. Multiple clinical classification methods are insufficient in guiding the selection of internal fixators. Meanwhile, the curative effects of sliding hip screw and cannulated compression screw in different fracture classifications are still controversial. Currently, there is a lack of appropriate theory to explain the occurrence of these complications and to prevent them. In this article, Based on the perspective of lever fulcrum reconstruction theory, Combined with the anatomical structure and biomechanical characteristics of proximal femur, the causes of complications related to internal fixation were revealed, and some suggestions were provided for the treatment of femoral neck fracture. The theory of lever fulcrum reconstruction explains the causes of internal fixation complications after previous treatment, and the treatment scheme recommended based on this theory has potential clinical significance, which provides a new concept for the treatment of femoral neck fracture.
