Effect of three cannulated compression screws combined with an obstructing screw on the biomechanical performance of pauwels type III femoral neck fractures: a finite element analysis

The combination of CCS and antishear OS demonstrated significant mechanical advantages and lower biological interference in the treatment of Pauwels type III femoral neck fractures. This method not only provides excellent mechanical stability but also ensures biological safety, offering benefits such as simplicity of operation, minimal invasiveness, and a low risk of complications. It holds great potential for widespread clinical application.
