In the treatment of Jones fracture, there is considerable variability in the literature regarding proper treatment of acute Jones fractures. The purpose of this study is to compare the outcomes of cast immobilization and intra-medullary screw fixation in the treatment of acute Jones fractures. Our results allowed us to demonstrate that in the treatment of Jones fracture type II and III by early intra-medullary screw fixation patients showed early union and return to their previous activity in shorter time than the conservative treatment.
