Comparative study on femoral neck fractures treatment: partial threaded cannulated screw versus different combinations of partial threaded cannulated screw and fully threaded headless cannulated screw

Abstract

For the treatment of femoral neck fractures, both the use of three partial threaded cannulated screw alone and the hybrid fixation with two fully threaded headless cannulated screw combined with one partial threaded cannulated screw can yield satisfactory clinical outcomes. However, compared to the former, although the latter demonstrates certain advantages in reducing femoral neck shortening, improving HHS, and cost-effectiveness, these findings should be interpreted with caution due to the retrospective design of the studies and potential biases. Based on current evidence, hybrid screw configurations appear to be a promising alternative; nevertheless, higher-quality prospective studies are warranted to validate their clinical superiority and support broader application.
