Abstract

Intramedullary screw fixation provides a less-invasive means of surgically managing metacarpal fractures. While there are advantages to using this technique compared to CRPP and ORIF, disadvantages of intramedullary screw fixation include loss of reduction intraoperatively due to sagittal and coronal plane translation. The blocking screw technique has been previously described as a solution for this problem in intramedullary fixation of long bone fractures. We describe the blocking screw technique as applied to aid intramedullary screw fixation of metacarpals.
