Fractures of scaphoid bone occur, as a rule, when falling on an elongated arm, with an emphasis on the wrist. Usually, the bone breaks into two parts of approximately the same size, only a fractured fragment will break down if the tubercle fractures.
Fractures of metacarpal bone account for 2.5% of all bone lesions in the skeleton. It should be noted that the mechanism of injury, the nature of the fracture and the type of displacement of injuries of the first metacarpal bone differ from the fractures of II-V metacarpal bones, so there is a need to consider these nosological forms separately.
