A proximal fifth metatarsal fracture, or a fracture of the bone of the outermost side of the foot, can occur acutely, such as after a twisting injury, or gradually over time as a stress fracture.
This injury can occur in any patient population but is usually seen in young, active people. This fracture will induce pain and swelling of the lateral foot and difficulty with weight-bearing and may present like an ankle or foot sprain.
