Boxer’s Fracture Fracture to the 4th and/or 5th metacarpal(s). MOI - caused by punching something harder than the hand, such as a wall or another person's head. The end of the metacarpal bone takes the brunt of the impact, which usually breaks through the narrowest area near the end (the "neck"), and bends down toward the palm.
