Blocking Screw Technique for Maintaining Reduction during Intramedullary Screw Fixation of Oblique Metacarpal Fractures

Intramedullary screw fixation provides a less-invasive means of surgically managing metacarpal fractures. While thereare advantages to using this technique compared to CRPP and ORIF, disadvantages of intramedullary screw fixationinclude loss of reduction intraoperatively due to sagittal and coronal plane translation. The blocking screw techniquehas been previously described as a solution for this problem in intramedullary fixation of long bone fractures.
