title: Articular fracture of the base of the thumb metacarpal: Comparative study between direct open fixation and extrafocal pinning.
abstract: The treatment of intra-articular fractures of the base of the first metacarpal bone should aim to anatomically reduce the articular surface, restore the initial length of the first metacarpal and preserve the opening of the first web space. These objectives appear to be achievable with a well-conducted surgical treatment. In a retrospective study, we reviewed a series of 38 cases, which compared open reduction and internal fixation (ORIF) and extrafocal pinning to determine which option provided the best reduction and functional recovery in young, manual workers. Direct fixation was better at restoring the configuration of the joint, regardless of the age and sex of the patients and the fracture type. This complete reduction is associated clinically with better function. Thumb opposition was statistically better in fractures treated by ORIF. Thumb retroposition was better in the cases treated by ORIF, but not significantly. ORIF appears the best technique for treating intra-articular fractures of the base of the first metacarpal, as it results in better functional recovery.
