Device for fixation of metacarpal bone fractures

Fixation of metacarpal bone fractures is usually performed using metal spokes, either intramedullary or transaxially. During transaxial fixation, as a rule, spokes are inserted in transverse or oblique planes in relation to the axes of the metacarpal bones. The disadvantage of these methods is the possibility of migration of spokes, insufficient stability of fractures, especially with simultaneous fractures of three or four metacarpal bones of the hand. Bone defects along the length do not exclude the possibility of bone settling with a decrease in its length, angular and rotational displacements.
