Research progress of cannulated screw internal fixation in the treatment of femoral neck fracture

Abstract

Femoral neck fracture refers to the destruction of the continuity of the femoral neck bone. Due to the special anatomical structure of femoral neck, the supply of blood vessels is often destructed after the fracture, which may result in fracture nonunion, femoral head necrosis, etc. How to choose a therapeutic method which can effectively avoid these consequences has been the focus of study in the treatment of femoral neck fracture. The therapeutic methods of femoral neck fracture include conservative treatment, internal fixation surgery, artificial hip replacement, etc. With the constant updating of internal fixtures and the application of artificial hip replacement, surgical treatment of femoral neck fractures has gradually replaced conservative treatment. To repair femoral neck fractures by internal fixation and try every means to keep the femoral heads is the mainstream of current surgical treatments. Hollow compression nail fixation is currently a well-recognized method of internal fixation. In recent years, further achievement has been scored on the basis of three hollow compression nails for the treatment of femoral neck fractures. In particular, the application of cannulated screw F technology has highlighted its advantages. It is expected to be applied in the future to treat displaced and osteoporotic femoral neck fractures. This article aims to review the new applications and related advances in the treatment of femoral neck fractures with three hollow compression nails.
