A Bennett fracture is a common injury that involves an intra-articular fracture at the base of the first metacarpal. This fracture typically results in a dorsally and radially displaced metacarpal shaft relative to the well-anchored volar ulnar fragment. Most Bennett fractures are treated with operative fixation, including closed reduction and percutaneous fixation, open reduction and internal fixation, or arthroscopically assisted fixation. However, the optimal surgical approach is controversial. There is a paucity of literature comparing the outcomes of the various treatments, leaving the surgeon without a clear treatment algorithm. Moreover, there is no consensus on acceptable reduction parameters, including articular gap or step-off, with some series stating that up to 2 mm of displacement is acceptable.
